摘要： An apparatus encodes a video signal for providing a scalable video coded (SVC) signal comprising a base layer video coded signal and an enhancement layer video coded signal, wherein the base layer video coded signal has more random access points, e.g., Instantaneous Decoder Refresh (IDR) slices, than the enhancement layer and in those access units where the enhancement layer has an IDR slice, the base layer has a non-IDR slice. Transmission of the SVC occurs in packet form using the Real-time Transport Protocol (RTP) such that non-random access point slices are conveyed in Simple Time Aggregation Packets (STAP), each Simple Time Aggregation Packet comprising a Payload Content Scalability Information (PACSI) Network Abstraction Layer (NAL) Unit.

摘要： A method and apparatus for fast channel change when changing the channel from a channel being viewed full screen as a main picture to a channel being viewed in a secondary channel program display window (e.g., a picture-in-picture (PIP) window). In one implementation, during the channel change, a secondary video stream (135) for a secondary channel program is up-sampled and displayed full screen while receiving the corresponding regular video stream (133) for the video program, of which program contents are identical to those of the secondary video stream. The program contents of the up-sampled secondary video stream is then be replaced seamlessly with those of the corresponding regular video stream (133) at the time when an instantaneous decode refresh (IDR) frame of the corresponding regular video stream (133) is received. In another implementation, the last GOP packets of the corresponding regular video stream (133), corresponding to a secondary video stream (135) being viewed in the secondary channel program display window, are buffered without being decoded. Upon a request for the channel change, the buffered GOP packets are decoded and displayed immediately while the decoder starts receiving the following frames in the corresponding regular video stream (133).

摘要： Methods for concealing Scalable Video Coding (SVC) decoding errors. Lost pictures in the target layer are replaced with up-sampled pictures from a lower layer, such as the base layer. In multiloop decoding applications, lost pictures in the target layer are replaced with corresponding up-sampled pictures from the lower layer. Subsequent target layer pictures in the same Group of Pictures (GOP) are either replaced with corresponding upsampled pictures from the lower layer, or they are decoded with up-sampled pictures from the lower layer used as reference pictures. For single-loop decoding, the bit stream of each layer is buffered, for each GOP, and inspected for errors. If an error is detected in the target layer, the pictures of the highest level layer without an error are decoded and up-sampled and used as the output pictures for the current GOP.

摘要： There are provided methods and apparatus for fast channel change when changing the channel from a channel being viewed full screen to a channel being viewed in a secondary display window (e.g., picture-in-picture (PIP) window). In one implementation, the base layer stream of the SVC encoded stream is used as the secondary stream for the secondary display and the corresponding enhancement layer stream is used as the corresponding regular stream. Upon channel change request, the decoded base layer picture of the SVC encoded stream is up-sampled, and the up-sampled base layer picture is displayed full screen while receiving the corresponding SVC enhancement layer stream. Then, the up-sampled base layer picture is replaced by the decoded enhancement layer picture upon confirmation of successful receiving and decoding of an enhancement layer instantaneous decode refresh (IDR) frame. In another implementation, the last GOP of enhancement layer stream corresponding to a base layer stream being viewed in the secondary display window is buffered without decoding, and upon a channel change request to the secondary video display window channel, the buffered packets are decoded and displayed immediately while the decoder continues to receive and decode all frames in the corresponding base and enhancement layer streams.

摘要： A traffic optimizer facilitates communication of data packets using a unicast protocol between a server and at least one of a plurality of clients through a multicast network. The traffic optimizer includes a communication processor and a packet processor. The communication processor receives both data including association data and the data packets using the unicast protocol from the server. The association data includes IP addresses of the server and IP addresses of at least one of a plurality of clients available for communication. The packet processor processes the data packets to optimize data transfer in response to an analysis of the data packets, and forwards the processed data packets to at least one of the plurality of clients at respective ones of the received IP addresses through a multicast network using the unicast protocol.

摘要： This invention relates to methods and apparatus for partitioning a data word into a protected region and an unprotected region in the link layer, forward error correction of a DVB-H module to provide unequal error protection of frames during forward error correction of the frames. IP-datagrams are encapsulated for coding after a pre-loading stage is initiated so that the reliability and importance of data in data frames corresponding to the IP-datagrams can be determined. Unequal error protection is further achieved by padding zeros in the unprotected region.
