This program is Shareware. To encode your own MPEG Audio files, you need to buy the MPEG Audio Software Encoder program for Win3.1 . [ Look above. Get some freeware encoder in software, much better !] --------------------------------------------------------------------------- ~Subject: SUBSECTION - WINDOWS-NT --------------------------------------------------------------------------- ~Subject: mpeg2ply [The June 30 edition of mpeg2w11 does not contain encoder port] MPEG Software Simulation Group codecs for Windows 32s (MPEG-L@netcom.com) MPEG2DEC.EXE and MPEG2ENC.EXE are Windows 32s ports with integrated display functions of the MPEG Software Simulation Group's programs. MPEG2PLY.EXE is the port of mpeg2play---Stefan Eckart's variation of mpeg2decode which optimizes speed through fast decoding methods such as approximation techniques, loop unravelling, et al. All Win32s programs were ported with Microsoft Visual C++. Only the main() program and display files (mpeg2dec.c, mpeg2enc.c, or mpeg2ply.c) differ from the standard "Unix distribution." If you do not have a 32-bit Windows environment (e.g. Win 4.0 Chicago, Windows NT), but plain old Windows 16 (e.g. Windows 3.1), yet you do possess either a 386, 486, or Pentium-based PC, you can download the Microsoft 32-bit extension program, "Win32s" from the Microsoft FTP site: URL=ftp://ftp.microsoft.com/developers/DEVTOOLS/Win32SDK/ [198.105.231.1] (this is the latest edition--June 23, 1994) Win32s archive (mpeg2w11.zip): mpeg2dec: mpeg2dec.c Main() routine. Initiates application and display. mpeg2dec.r MS Visual C++ resource file. makefile MS Visual C++ project file. gui.h #include constants for MS GUI values. mpeg2dec.exe Speed-optimized executable grayleo.ico mpeg2dec.exe 32x32 4-bit System Palette icon About the windows icon: The 32x32 4-bit icon for MPEG2DEC.EXE and MPEG2ENC.EXE is a silhouette of Dr. Leonardo Chiariglione (CSELT, Italy), none other than our co-founder and exhaulted lifetime Convenor of MPEG. Acknowledgement: Many thanks to Sorin Papuc (sop@compcore.com) for porting these programs to Windows 32s. --------------------------------------------------------------------------- ~Subject: mpegplay [ This new version of it, is running now extremly nice, the subsystem ] [ is no harm at all. The file should be known as MPEGW32W.ZIP. ] From: michael@ecel.uwa.edu.au (Michael Simmons - division) MPEGPLAY V1.61 (c) 1993,1994 Michael Simmons Please READ ALL of this file! This is Release Version 1.61 of my port of the Berkeley mpeg player. Note this version requires the WIN32s V1.15a Windows(tm) Extender. Also this version will only work under (beta 612) of Windows NT(tm) V3.5 or later. Features added in this version include (1) Support for MPEG1 System Layer files (you don't have to split them now). (2) Support for the Microsoft(tm) WinG(tm) Windows(tm) gaming library. (3) Improved colours for the Ordered and 2x2 Order dithers. (4) "Save As" For all the Mosaic Users. (5) Improved Error handling for corrupt/non standard mpeg files. (6) Support for CDI(tm) and VideoCD Streams. Either as an extracted MPEG sequence or as a RAW CDROM grab. (7) Recompiled using the Microsoft Daytona(tm?) (beta 612) SDK Compiler. Please Email me with any suggestions you may have on improving the player! (See the section CONTACTING ME). This player can play standard mpeg files that include P and B frame encoding, and large 354x288 movie files. It has several display options including mono, gray scale, color dither and Full colour (for Hicolor graphic cards). 8MB of Ram or greater is recommended if large Image size MPEG files are played. This program is SHAREWARE Please read the REGISTER.TXT file for information on registering your copy. To install the player. If you don't have Win32s V1.15a installed, install it first. Unzip the file disk1.zip to a floppy disk. Then run the setup.exe file via the Progman File-Run Menu Item. Note: This will also install the Microsoft WinG(tm) extensions to Windows(tm) Should you wish to remove these extensions at a later date please refer to the section near the end of this Readme.txt file. Read the Disclaimer in the online Help before loading any mpeg movie files. The latest version of this software can be found first on URL=ftp://ftp.ecel.uwa.edu.au/users/michael/ UNREGISTERED VERSION LIMITATIONS: The unregistered version will display the About box at startup. IT WILL ALSO NOT HANDLE FILES BIGGER THAN 1MB! DISTRIBUTION: The Unregistered Version of the Player may be freely Re-Distributed so long as (1) None of the files are modified. (2) All files in this archive are re-distributed together. (3) None of the files are removed from this archive. (4) It is clearly stated that this program is Shareware, extended use of which requires payment to myself Michael Simmons as described in the players about box and the REGISTER.TXT file. (5) If any additional files are added it must be clearly stated which files have been added, who added these files and why!. It must be stated that I "Michael Simmons" am in no way responsible for these additional files. (6) None of the added files can instruct the user or modify the player in any way possible to enable the Unregistered Version Limitations to be overcome. The Registered Version may only be Re-Distributed with my written approval. KNOWN BUGS: The player does not like certain PD/Shareware desktop addons (Clocks etc). A small number of people are getting a GPF in POINTER.DLL. If you have this problem and solve it please contact me. So far I can not reproduce the fault. The player does not multitask while scanning a file to determine whether or not it is a system layer or straight video file. This is only a problem on large misaligned RAW CDI or VideoCD grabs. RAW CDI or VideoCD grabs have only be tested on 4 CDI Disks. Given the variation found between these disks I would not be surprised if there are problems with some disks. If you are having a problem with a certain CDI/VideoCD disk please send a copy (both original CD's) of it to me. If I don't already have it I will treat it as a registration fee. If you have a problem and are really stuck try and find a machine on which it works and compare the two configurations. If you really really get stuck then see the section CONTACTING ME.

Our last estimate was that over 60,000 copies of the decoder have been FTP'd since the first release in November 1991, and over 15,000 copies of the encoder have been FTP'd since it was released in July 1993. For other information on multimedia research at U.C. Berkeley, see the home page for the Plateau Multimedia Research Group. http://www-plateau.cs.berkeley.edu/plateau.html Further about the FTP site is included in INDEX. See ANNOUNCE for our posted announcement of the tools.

Rowe, Kevin Gong, Eugene Hung, Ketan Patel, Steve Smoot and Dan Wallach Computer Science Division-EECS, Univ. of Calif. at Berkeley This directory contains the freely distributed Berkeley MPEG-1 Video Encoder. The encoder implements the standard described in the ISO/IEC International Standard 11172-2. The code has been compiled and tested on the following platforms: DECstation 5000 and Alpha HP PA-RISC (HP/UX 9.X) (i.e., HP 9000/7XX and 9000/3XX) SGI Indigo running IRIX 5.0.1 Sun Sparc (SunOS 4.X) In addition, Rainer Menes from the Technical University of Munich has ported the encoder and decoder to the Macintosh. You can get that code directly from him (menes@statistik.tu-muenchen.de), or from the Berkeley FTP archive (mm-ftp.CS.Berkeley.EDU). If you decide to port the code to a new architecture, please let us know so that we can incorporate the changes into our sources. This directory contains everything required to build the encoder and run it. We have included source code, makefiles, binaries for selected platforms, documentation, and test data. Installation instructions are given in the file named src/mpeg_encode/INSTALL. A man page is given in the file doc/mpeg_encode.1. A detailed user manual is provided in postscript format in the file doc/user-manual.ps. The encoder will accept any input file format as long as you provide a script to convert the images to PPM, YUV, JPEG, or JMOVIE format. Input file processing is described in the file doc/INPUT.FORMAT. Options to control input file processing and compression parameters are specified in a parameter file. Very little error processing is done when reading this file. We suggest you start with the sample parameter file examples/template.param and modify it. See also examples/default.param. The convert directory of Mpeg-Tools contains utilities you might find useful including: programs to do PPM/YUV conversion and programs to convert Parallax XVideo JPEG files into PPM, YUV, or JPEG frames. The motion vector search window can be specified, including half-pixel block matching, in the parameter file. We have implemented several search algorithms for P-frames including: 1) exhaustive search, 2) subsampled search, and 3) logarithmic search. We have also implemented several alternatives for B-frame block matching including: 1) interpolate best forward and best backward block, 2) find backward block for best forward or vice-versa (called CROSS2), and 3) exhaustive cross product (i.e., go out for coffee and a donut!). The search algorithms are controlled by options in the parameters file. For tips on choosing the right search technique, see the user manual. The encoder can be run on one computer (i.e., sequential) or on several computers (i.e., parallel). Our goal is to produce a portable, easy-to-use encoder that we can use to encode large volumes of video material for the Berkeley VOD system (see paper VodsProp93.ps.Z on the FTP archive). The parallelism is done on a sequence of pictures. In other words, you can spawn one or more children to encode continuous runs pictures. The uncompressed data can be accessed either through NFS or TCP sockets. The goal is to allow you to encode using multiple processors, think spare cycles on workstations, to speed up the encoding time. Although performance depends on the speed of individual processors, the file system and network, and the P/B frame search methods, we have encoded 3.75 frames/second on 8 HP Snakes running in parallel as compared with 0.6 frames/second on 1 Snake. These are preliminary results. We are continuing to experiment with and tune the code. Instructions to run the parallel system are given in the man page and the parallel.param example parameter file. We have done some tuning to produce a reasonable encoder, but there are many more optimizations that we would like to incorporate. These extensions are listed in the file doc/EXTENSIONS. If you succeed in implementing any of them, please let us know! Send bug reports to: mpeg-bugs@CS.Berkeley.EDU Problems, questions, or patches should be sent to this address.

Rowe, Ketan Patel, Brian Smith, Steve Smoot, and Eugene Hung Computer Science Division-EECS, Univ. of Calif. at Berkeley This directory contains a public domain MPEG video software decoder. The decoder is implemented as a library that will take a video stream and display it in an X window on an 8, 24 or 32 bit deep display. The main routine is supplied to demonstrate the use of the decoder library. Several dithering algorithms are supplied based on the Floyd-Steinberg, ordered dither, and half-toning algorithms that tradeoff quality and performance. Neither the library nor the main routine handle real-time synchronization or audio streams. The decoder implements the standard described in the Committee Draft ISO/IEC CD 11172 dated December 6, 1991 which is sometimes refered to as "Paris Format." The code has been compiled and tested on the following platforms: HP PA-RISC (HP/UX 9.X, X11R5) (i.e., HP 9000/7XX and 9000/3XX) Sun Sparc (SunOS 4.X, X11R5) DECstation 5000 and Alpha Silicon Graphics Indigo MIPS RISC/os 4.51 If you decide to port the code to a new architecture, please let us know if there are any significant changes, so that we can incorporate them into our sources. This directory contains everything required to build and display video. We have included source code, a makefile, an Imakefile, installation instructions, and a man page. Data files can be obtained from the same ftp site this was located in. See the INSTALL file for instructions on how to compile and run the decoder. The data files were produced by XING. XING data does not take advantage of P or B frames (ie, frames with motion compensation). Performance of the player on XING data is significantly slower (half or less) than the performance when motion compensated MPEG data is decoded. We are very interested in running the software on other MPEG streams. Please contact us if you have a stream that does not decode correctly. Also, please send us new streams produced by others that do utilize P and B frames. Our future plans include porting the decoder to run on other platforms, integrating it into a video playback system that supports real-time synchronization and audio streams, and further experiments to improve the performance of the decoder. Vendors or other organizations interested in supporting this research or discussing other aspects of this project should contact Larry Rowe at Rowe@CS.Berkeley.EDU. Other Versions: There are three variations of the old mpeg_play: One added a very nice Motif interface (variously named mpeg_play-2.0.1 and xmpegplay). One was mpegvga.patch and let linux play straight to a VC. One was an X interface (mpegplayer.tar.gz on linux sites) We have notified the authors of those programs, and will have new versions of them here as soon as they can find the time to update them. Reporting bugs: If you find any bugs in this software, please send them to mpeg-bugs@plateau.cs.berkeley.edu. Since this software is unsupported, we make no guarantees about how long it will take to fix the bug, or if it will be fixed at all. Bug fixes will be cheerfully accepted.

Rowe, Doug Banks, Steve Smoot, and Sam Tze-San Fung Computer Science Division-EECS, Univ. of Calif. at Berkeley This directory contains a public domain tool to monitor and modify MPEG video streams. mpeg_bits takes as input an mpeg stream and presents graphical feedback on the distribution of bits in the stream, on a macroblock-by-macroblock level. mpeg_bits also provides a simple user interface to generate specifics files that can be used by mpeg_encode to re-encode a stream, modifying the encoding on a macroblock-by-macroblock level. [The present version of mpeg_encode does not support this..] This tool does not support system layer streams. mpeg_bits supports the standard described in the Committee Draft ISO/IEC CD 11172 dated December 6, 1991 which is sometimes refered to as "Paris Format." The code has been compiled and tested at least once on the following platforms: HP PA-RISC (HP/UX 9.X, X11R5) (i.e., HP 9000/7XX and 9000/3XX) Sun Sparc (SunOS 4.X, X11R5) If you decide to port the code to a new architecture, please let us know about important changes, so that we can incorporate the changes into our sources. This directory contains everything required to build and use mpeg_bits. We have included source code, a makefile, installation instructions, and a man page. See the INSTALL file for instructions on how to compile and run the analyzer. Our future plans consist of more fully supporting an interactive editor paradigm; specifying changes directly on the display, seeing the results of edits on the video stream immediately as they occur, etc. We would also like to port the code to run on more platforms, and add support for system layer streams. Vendors or other organizations interested in supporting this research or discussing other aspects of this project should contact Larry Rowe at Rowe@CS.Berkeley.EDU.

XMG has several options that modify its behaviour, but it also provides sensible defaults for most of them. The two switches that you'll use most of the time are -fps (or -fpm) and -frames. These specify the number of frames per second (or per minute) and the total number of frames to grab. Here's an example invocation : xmg -fps 1 -frames 20 This specifies that we want to grab 20 frames, one per second, and also that we want to see what's going on during the grabbing process. At this point the XMG window will appear : Click on the "Grab" button and then click with the left mouse button inside the window that you want to grab. Once you've done this, the grabbing process will begin immediately, displaying some progress information as it does it. It is possible to change a few parameters directly from inside the window, instead of specifying them on the command line. When all the frames have been grabbed, the MPEG encoding process begins: go off and make yourself a nice cup of tea and come back later. By default the program creates a file called xmgout.mpg in the current directory. This file can then be viewed with any MPEG player which supports I,P and B frames of any size (Xing for example, doesn't support them). You can specify a different name for the output file with the -output switch. For example, the command : xmg -fps 1 -frames 20 -output mympeg.mpg will create a file called mympeg.mpg. When XMG is grabbing the frames, it stores them in a temporary RLE compressed and archived format called XLA. This file can become quite large very quickly, especially if you're grabbing several frames of a certain size. This file will be created by default in the /tmp directory with the name xmgtmp.$$$. This can be changed with the -tmp option : xmg -fps 1 -frames 20 -tmp /empty/xmpeggrab.tmp which will create it in the /empty directory with the name xmpeggrab.tmp. Make sure you've got plenty of space on the device ! To actually perform the encoding, XMG requires a parameter file. By default this file is called xmg.param and has to be in the current directory. Don't worry if you haven't got one : XMG will create a default one for you and use that. A different parameter file can be specified with the -param switch : xmg -fps 1 -frames 20 -param flower.param This will use the file flower.param. A description of the possible contents of the paramter file is provided later on. SYNOPSIS ++++++++ xmg -help -display host:dpy -frames nframes -fps nfps -fpm nfpm -terse -output filename -tmp filename -param filename OPTIONS +++++++ -fps nfps : specifies the number of frames per second to grab. Even if the machine you're using is slow, XMG will grab the server during the grab, so that no other application can write to the screen at the same time. As soon as the frame has been grabbed, the server is released so that the other applications can redraw their client area. -fpm nfpm : specifies the number of frames per minute to grab. -frames nframes : specifies the number of frames to grab in total. -output filename : specifies a name and location for the generated MPEG stream. By default XMG creates a file in the current directory called xmgout.mpg. -tmp filename : specifies a name and location for the temporary storage of the grabbed frames. This file is deleted when XMG has completed the encoding process. The default is /tmp/xmgtmp.$$$ -terse : does not display the XMG status window during the grabbing/encoding process. The default is to display the XMG window. -param : specifies a name and location for the parameter file. By default the file is called xmg.param and has to be in the current directory. If one doesn't exist, a default one will be created for you. PARAMETER FILE ++++++++++++++ The parameter file MUST contain the following lines : PATTERN pattern --------------- pattern is a sequence of I's, P's and B's, that specifies the order of the frames in the MPEG stream. GOP_SIZE n ---------- n is roughly the number of frames in a Group of Pictures (roughly because a GOP must begin with an I-frame) SLICES_PER_FRAME n ------------------ n is roughly the number of slices per frame. Note, at least one MPEG player may complain if slices do not start at the left side of an image. To ensure this does not happen, make sure the number of rows is divisible by SLICES_PER_FRAME. PIXEL (FULL or HALF) -------------------- use half-pixel motion vectors, or only full-pixel ones RANGE ------ use a search range of +/- n pixels PSEARCH_ALG algorithm --------------------- algorithm must be one of {EXHAUSTIVE, TWOLEVEL, SUBSAMPLE, LOGARITHMIC}. Tells what kind of search procedure should be used for P-frames. Exhaustive gives the best compression, but logarithmic is the fastest. You select the desired combination of speed and compression. TWOLEVEL is an exhaustive full-pixel search, followed by a local half- pixel search around the best full-pixel vector (the PIXEL option is ignored for this search algorithm). BSEARCH_ALG algorithm must be one of {SIMPLE, CROSS2, EXHAUSTIVE}. Tells what kind of search procedure should be used for B-frames. Simple means find best forward and backward vectors, then interpolate. Cross2 means find those two vectors, then see what backward vector best matches the best forward vector, and vice versa. Exhaustive does an n-squared search and is EXTREMELY slow in relation to the others (Cross2 is about twice as slow as Simple). IQSCALE ------- use n as the qscale for I-frames PQSCALE ------- use n as the qscale for P-frames BQSCALE ------- use n as the qscale for B-frames REFERENCE_FRAME (ORIGINAL or DECODED) ------------------------------------- If ORIGINAL is specified, then the original images are used when computing motion vectors. To be more accurate, use DECODED, in which the decoded images are used. This should increase the quality of the image, but will take a bit longer to encode. The lines may appear in any order, except the following exceptions. NOTES +++++ If XMG was compiled with the -DMITSHM switch enabled, then shared memory will be used if available and will increase performance noticeably.

It is based on the Berkeley MPEG player v2.0, utilizing the Berkeley parsing and decoding routines for the MPEG data stream. MPEGSTAT is a useful utility for analyzing MPEG-I video streams. It is based on the Berkeley MPEG movie player. MPEGSTAT reads a video stream from a file or stdin and shows the frame type pattern as it is found while parsing. After the stream is completely parsed it displays the frame pattern as it would be displayed by a MPEG viewer. It then generates a summary of various mpeg format related statistics. MPEGSTAT works for MPEG movies that are Paris format compatible.

SCHLICHTER * * * ********************************************************************* Hello all. This is an announcing for all of those that have already been waiting on the release of my code for multiplexing one MPEG 1 Audio and one MPEG 1 Video Stream into a MPEG 1/SYSTEMS multiplexed data stream according to the ISO/IEC 11172-1 specs. Sorry for all of those that needed the code really bad and kept mailing me on it. I couldn't hold my promises because of copyright release on part of the University. But here it is: I uploaded the source code on URL=ftp://hpsystem2.informatik.tu-muenchen.de//pub/comp/graphics/mpeg/mplex/ [131.159.0.198] ftp.informatik.tu-muenchen.de .gz means it is compressed with GNU zip. Should somebody not have it, you can find it on our FTP server under /pub/comp/gnu/gzip/ else, just try get mplex-1.0beta.tar.Z Our FTP server will do an on-the-fly-compressing with the 'compress' (.Z) format. Now to the code itself: I have been kept really busy with my papers on multiplexing (they will shortly be available on the FTP server also, I will post on that), so sorry if I couldn'g tighten the code up a bit. There is no real docu- mentation yet, please try out the code. Feel free to email me for any further questions. As of now, this code will only run under standard UN*X-Style platforms providing a (K&R-Style) C compiler (GNU CC is fine). It tested fine on SUN's, HEWLETT PACKARD's series 700, SILICON GRAPHICS machine's. There is * NO DOS PORT AVAILABLE (YET) *. Contact me if you are planning such a thing. There will be better releases, and I promise to clean up the code soon. :) This Software is released under the terms of the GNU public license, see the tar archive for further details. Feel free to archive the code on other FTP servers or post it to newsgroups, if there is such interest.

The first, fully-featured MPEG-player with X11-interface. ] [ XMPLAY exists currently in Version 1.0, patches are available. The next ] [ Version 1.1 is currently in development. Thats the announcement ! ] XMPLAY [Version 1.1] - Sun Apr 10 14:51:22 MDT 1994 This distribution is the result of a project worked out at the Technical University (TU) Berlin, held in Winter 93/94 by Tom Pfeifer. The basic idea is created by Frank Gadegast, the programing work was then done by Juergen Meyer, Metin Cetinkaya and Frank Gadegast. This software is ftp-able from: http://www.powerweb.de/mpeg [ Just to remember .gz means, its compressed using GNU's zip, called ] [ gzip. Use gunzip to uncompress. ] XMPLAY [Version 1.1] <IMG SRC="xmplay1.gif"> <IMG SRC="xmplay2.gif"> XMPLAY is a very nice directory-browser under X11 to use XMPEG, the interactive X11-MPEG-player. MPEG is a video-format described by the ISO-standard ISO CD11172. This implementation here can handle MPEG-stream written down at the MPEG-group-meeting in Paris '92. It can handle IPB-frames but no system- nor audio-information. <IMG SRC="xmplay3.gif"> <IMG SRC="xmplay4.gif"> Additional you get a little utility called MPEGINFO, showing you, if called with the filename of a MPEG-file the most important parameter it can read dirrectly from its header, like size, picture rate or frame-style. It should work under nearly every system, 'cause it's programed without MOTIF, the X11-Toolit or other stupid things, that are always causing problems. It only needs the X11-library, no matter if you're using Release 3, 4 or Release 5. In addition it has lots of defines to let it run under BSD, SYSV, ISC, Solaris, SunOS, A/UX, SCO or XENIX and you don't have to hack a difficult Imake- or Makefile and you will not have trouble with build-in pathnames !!! It's specially made for those systems, that don't have super hardware or that have problems with the Toolkit or MOTIF. XMPEG [Version 1.1] <IMG SRC="xmpeg1.gif"> <IMG SRC="xmpeg3.gif"> XMPEG is a MPEG-video-player based on the MPEG-widget-implementation from Jim Frost and the MPEG-movie-player "mpeg_play" from the Portable Video Research Group at Berkeley. It just adds a few buttons and is normally getting called from XMPLAY, but can be used as stand-alone to include into other programs. Its programmed with the same methods than XMPLAY. <IMG SRC="xmpeg2.gif"> <IMG SRC="xmpeg4.gif"> You can download XMPLAY from http://www.powerweb.de/mpeg. If you get problems (not really possible) to compile it or if you have comments send them to the authors, reachable at: phade@powerweb.de (responsible for compiling and X11) jm@cs.tu-berlin.de (responsible for the mpeg-code) or brain@cs.tu-berlin.de --------------------------------------------------------------------------- User Contributions:Comment about this article, ask questions, or add new information about this topic: |

simply, Their ire is being provided to referee Pete Morelli, Whose officiating crew flagged the Eagles 10 times for 126 yards contrary to the Panthers while calling only one penalty for one yard against Carolina. It was a discrepancy of historic hordes:
This was the brand new in NFL history one team had over 120 penalty yards while the other had fewer than 10. It had pretty much 60,000 online signatures by stock exchange.
[Eagles sit atop Week 6 power evaluations, Supplanting the type of Chiefs]
"NFL Referee Pete Morelli has a clear and statistically obvious bias on the Philadelphia Eagles, Philbrick contributes. [url=https://ukrainianwomen.home.blog/]dating ukrainian women[/url] "during the last four games that he has officiated that the Eagles were playing in, The Eagles were flagged an overall of 40 times for 396 yards, though Eagles opponent in those games were flagged a mere 8 times for 74 yards. This is inappropriate and puts the Philadelphia Eagles at a disadvantage. Preventing Morelli from refereeing Eagles games will result in a more trustworthy and honest NFL. This will this entire league and keep all claims of conspiracy to a normal level,
Morelli's work comes under fire before. looking for string of officiating gaffes in the 2015 season, His crew was not selected to work the postseason and then was broken up after the season, A signal by the NFL otherwise enamored with Morelli's officiating team. once you get your squad, Morelli was extremely popular playoffs last year, around the other hand, Officiating the AFC second round game between Patriots and the Texans.
Since growing an NFL referee in 2003, Morelli has led the officiating crew in 15 games between Eagles (Three regarding playoff games). Philadelphia has gone 8 7 in those games, along with 2 1 in the postseason. nevertheless, The Eagles are 2 6 inside their past eight games with Morelli as referee, And the calls have not gone their way within the last few four: Philadelphia could be flagged 40 times for 396 yards over that span; Its opponents have drawn just eight fine for 74 yards.
Week 5 was not seen as a very strong one for NFL officials. apart from the Eagles' fans complaints about Morelli, The Jets had a touchdown and the ball taken away from them from the Patriots after the officials ruled that tight end Austin Sefarian Jenkins fumbled it out of bounds in the end zone, A decision that baffled just about everybody who saw replays of the play.
