| 20090201805 | FORWARD ERROR CORRECTION BASED DATA RECOVERY WITH PATH DIVERSITY - A media source sends media packets over a first media path. Repair packets are encoded from the media source packets and sent over a second different media path. Sending the source packets and repair packet over different media paths is referred to as Forward Error Correction (FEC) spatial diversity and reduces the amount of repair packet overhead required for repairing the media source packets in case of a network outage or packet loss. To provide load balancing, a first set of media streams may be sent over the first media path and a second set of media streams may be sent over the second media path. If a fault is detected on one of the media paths, then the repair packets may no longer be transmitted and the one or more media streams from the disabled media path are transmitted over the working media path. | 08-13-2009 |

| 20110072148 | Distributed Coordination of Network Elements for Packet Encapsulation - In one embodiment, each of a plurality of encapsulator devices receives a source stream of encoded packets in a first transport format to be converted to packets of an output stream in a second transport format for communication over a data network. Each encapsulator device generates a one or more fundamental identifying characteristics for the output stream based on information contained in one or more fields of a packet in the source stream so that the packets in the output stream generated by each of the encapsulator devices from the source stream are coordinated with respect to each other. | 03-24-2011 |
| 20110075997 | DECODING EARLIER FRAMES WITH DTS/PTS BACKWARD EXTRAPOLATION - In one method embodiment, receiving a video stream comprising a first compressed picture without associated time stamp information and a second compressed picture having associated first time stamp information, the second compressed picture following the first compressed picture in transmission order; deriving second time stamp information based on the first time stamp information; and processing the first compressed picture based on the second time stamp information. | 03-31-2011 |
| 20110119546 | RTP-BASED LOSS RECOVERY AND QUALITY MONITORING FOR NON-IP AND RAW-IP MPEG TRANSPORT FLOWS - In one method embodiment, transmitting a transport stream formatted according to a defined coding specification to a receive-and-process (RP) system, the transport stream format further comprising a non-Internet protocol (IP) format or a raw-IP format; providing a mapping stream, the mapping stream correlating the transport stream to a Real-time Transport Protocol (RTP)-formatted data stream that encapsulates the transport stream, the mapping stream comprising identifying information corresponding to the transport stream and second identifying information corresponding to the data stream; and transmitting the mapping stream to the RP system over an IP connection to enable RTP capabilities at the RP system. | 05-19-2011 |

| 20100254673 | SUPPLEMENTARY BUFFER CONSTRUCTION IN REAL-TIME APPLICATIONS WITHOUT INCREASING CHANNEL CHANGE DELAY - Embodiments may be disclosed herein that provide systems, devices, and methods of processing a program stream, the program stream comprising a video and an audio stream. One such embodiment is a method comprising: initializing an audio reference clock to a value associated with a presentation timestamp for a decodable audio frame which is the first audio frame capable of being decoded in the audio stream; initializing a video reference clock to a value associated with a presentation timestamp for a decodable video frame which is the first video frame capable of being decoded in the video stream; storing audio frames received prior to receipt of the decodable video frame which is the first video frame capable of being decoded in the video stream in an audio frame buffer; starting audio and video reference clocks after a video preroll delay, which is the difference between the first decodable video frame PTS and the value of PCR at the time that PTS is received, has elapsed; decoding the audio stream in accordance with the audio reference clock; and decoding the video stream in accordance with the video reference clock. | 10-07-2010 |
| 20110051607 | CAPACITY/AVAILABLE BANDWIDTH ESTIMATION WITH PACKET DISPERSION - Consistent with embodiments of the present invention, systems and methods are disclosed for estimating at least one of a capacity and an available bandwidth of a communications path. Methods may be disclosed comprising: sending a measurement request to a computing device on a network and receiving data responsive to the measurement request. At least one of a capacity and an available bandwidth of a communications path from the sender to the computing device may be estimated based on the received data. The estimation may be sent to the computing device and stored. Transmission settings may be adjusted based on the estimation. | 03-03-2011 |

| 20100005360 | IMPORTANCE-BASED FED-AWARE ERROR-REPAIR SCHEDULING - Particular embodiments generally relate to providing retransmission that is forward error correction (FEC) aware. In one embodiment, information is received that defines a plurality of missing packets for a media stream for a receiver. The plurality of missing packets may define FEC packets and source packets that are missing at the receiver. A retransmission server determines one or more retransmission packets for retransmission based on the FEC packets and source packets received at the receiver. In taking into account the FEC packets and source packets received at the receiver, retransmission of all missing source packets may not be necessary. The one or more retransmission packets are then sent to the receiver and the receiver can use the one or more retransmission packets to recover the plurality of missing source packets. The retransmission server may take into account the FEC and source packets received at multiple receivers and perform error repair such that a maximum total number of source packets can be repaired at all receivers. | 01-07-2010 |
| 20100111108 | Systems and Methods of Reducing Delay in Decoding - In one embodiment, a method includes inserting a packet containing an interpolated timestamp into a burst media stream. The insertion is responsive to a channel change request. The burst media stream includes a series of cached frames. | 05-06-2010 |
| 20100188989 | MONITORING OF REAL-TIME TRANSPORT PROTOCOL (RTP) PACKET FLOW ALONG RTP PATH - Techniques are provided herein to enable monitoring of a real-time transport protocol (RTP) packet flow in devices along the path that the RTP packet flow traversed from a source to a destination. A device that is a source or destination of a RTP packet flow transmits a monitor request message that requests one or more other devices along a path of the RTP packet flow to monitor the RTP packet flow. The device that is the source or destination of the RTP packet flow receives one or more monitoring reports from the one or more other devices along the path of the RTP packet flow. This allows a device that requested monitoring of the RTP packet flow to analyze the monitor reports in order to determine a location of a cause of reduced performance in the RTP packet flow. e.g., missing packets, overly delayed packets, etc. | 07-29-2010 |

| 20100153252 | PROOF OF MAILING - Methods and systems for providing a proof of mailing service include receiving from a user a designation of a recipient to receive an item to be mailed, and receiving a free-form description of the item. Postage indicia is printed bearing an amount of postage for a mail piece containing the item. In response to the mail piece being processes by a postal authority, a transmission from the postal authority containing a scanned image of the mail piece is received. The recipient is then sent a notification that the item has been mailed, and the notification includes the free-form description of the item and access to the scanned image. | 06-17-2010 |
