20130329781 | TECHNIQUES FOR ADAPTIVE VIDEO STREAMING - A vide coding server may code a common video sequence into a plurality of coded data streams, each coded data stream representing the video sequence coded using coding parameters tailored for a respective transmission bit rate. The coding may cause a set of transmission units from among the coded data streams to include coded video data from a common point of the video sequence, and a first coded frame of each transmission unit of the set to be a synchronization frame. A manifest file may be built representing an index of transmission units of the respective coded data streams. The coded data streams and manifest file may be stored by the server for delivery to a client device. During download and decode, the chunks may be decoded efficiently even when switching among streams because the first frame in each chunk is a synchronization frame. | 12-12-2013 |
20140029663 | ENCODING TECHNIQUES FOR BANDING REDUCTION - Video encoders often produce banding artifacts on areas with smooth gradients and low levels of detail/noise. In this disclosure, a video encoding system identifies the banded areas and adjusts coding parameters accordingly. The video coder may include a pre-coding banding detector and a post-coding banding detector. The pre-coding detector may identify regions in the input picture with smooth gradients that are likely to have banding artifacts after encoding. The post-coding detector may identify regions in the reconstructed picture with visible banding. Usage of pre-coding detector and/or post-coding detector depends on how an encoder operates. In a single-pass encoding or during the first pass of a multi-pass encoding, the pre-coding detection maps are used. During picture re-encoding or during later passes of a multi-pass encoding, the post-coding detector maps are used. | 01-30-2014 |

20140241415 | ADAPTIVE STREAMING TECHNIQUES - Systems and methods are presented for minimizing the suddenness and immediacy of changes to the video quality perceived by users due to bandwidth fluctuations and transitions between different bitrate streams. A method may include identifying an upcoming bitrate change in a bitstream and a nearest scene cut boundary from sync frame scene cut tags included in the bitstream. The method may include calculating whether waiting until the identified nearest scene cut boundary before changing the bitrate will cause the buffer to drop below a threshold. When the buffer is calculated to not drop below the threshold, the method may postpone the upcoming bitrate change until the identified nearest scene cut boundary. | 08-28-2014 |
20140269932 | CODEC TECHNIQUES FOR FAST SWITCHING - A video streaming method for transitioning between multiple sequences of coded video data may include receiving and decoding transmission units from a first sequence of coded video data. In response to a request to transition to a second sequence of coded video data, the method may determine whether a time to transition to the second sequence of coded video data can be reduced by transitioning to the second sequence of coded video data via an intermediate sequence of coded video data. If the time can be reduced, the method may include receiving at least one transmission unit from an intermediate sequence of coded video data that corresponds to the request to transition, decoding the transmission unit from the intermediate sequence, and transitioning from the first sequence to the second sequence via the decoded transmission unit from the intermediate sequence. | 09-18-2014 |
20140321534 | VIDEO PROCESSORS FOR PRESERVING DETAIL IN LOW-LIGHT SCENES - Video coding systems and methods are provided that protect against various artifacts (e.g., banding artifacts) in decoded frame content. The embodiments to protect against introducing artifacts include pre-processing the input video frame, controlling the encoding parameters and/or post-processing the decoded video frame.

The frame may be filtered based on the altered filtering parameters and encoded. | 10-30-2014 |

20160073106 | TECHNIQUES FOR ADAPTIVE VIDEO STREAMING - In a video coding system, a common video sequence is coded multiple times to yield respective instances of coded video data. Each instance may be coded according to a set coding parameters derived from a target bit rate of a respective tier of service. Each tier may be coded according to a constraint that limits a maximum coding rate of the tier to be less than a target bit rate of another predetermined tier of service. Having been coded according to the constraint facilitates dynamic switching among tiers by a requesting client device processing resources or communication bandwidth changes. Improved coding systems to switch among different coding streams may increase quality of video streamed while minimizing transmission and storage size of such content. | 03-10-2016 |

20090285307 | Video Concatenation for MPEG-4 and H.263 Bit Streams - A method for concatenating MPEG-4 or H.263 segments is provided. The method includes extracting and comparing the VOL or picture header information of each segment. If the two segments have the same VOL or picture header information, the method merges the two segments directly by appending one segment to another to form a new bit stream. If the two segments have the different resolution, the method completely decodes and re-encodes the segments and then merges the segments. Otherwise the method takes the VOL or picture header information of one segment as reference to produce the new bit stream. The method parses the other segment frame at a time, re-encapsulates it according to the reference VOL or picture header information, and appends it to the one segment. During the process, the method only uses VLD to parse the other segment without using the tools of DCT, IDCT, ME, and MC. | 11-19-2009 |
