摘要： De-jittering a transport stream, at least some transport packets of the transport stream carrying audio-video data and at least some of the transport packets of the transport stream containing Program Clock References (PCRs). A data buffer receives the transport packets and stores the transport packets. Pacing counter clock circuitry produces a pacing counter clock and adjusts the pacing counter clock based upon a pacing counter clock adjust signal. Pacing control circuitry produces the pacing counter clock adjust signal based upon receipt of the transport packets. PCR packet pacing circuitry receives the pacing counter clock, based upon the packing counter clock, retrieves transport packets from the data buffer, and transmits the retrieved transport packets as an output transport stream. The pacing counter clock adjust signal may be based upon data buffer fullness or based upon an estimated program clock generated from the PCRs.

摘要： Aspects of fast channel change of programs are presented. Initial pictures of a program may be decoded earlier and displayed longer than what is indicated by corresponding clock references. Additional pictures of the program may be decoded and displayed at time indicated by the clock references. Within the time period of the initial pictures, decoding timing advances of initial pictures may be reduced and corresponding picture displaying rates may converge to an intended constant frame rate used for additional pictures displaying. Pictures may be decoded and displayed when the corresponding data are available in a coded data buffer (CDB) and a decoded picture buffer (DPB), respectively. Depending on the implementation, the respective previous picture may be displayed when a decoded picture is available in the DPB.

摘要： A 3-dimensional (3D) video transmitter may be operable to determine a modification process to be utilized for modifying an enhancement layer of a 3D video frame before encoding of the enhancement layer. The modification process may provide increased compression efficiency during the encoding. The enhancement layer may be modified utilizing the determined modification process. The modified enhancement layer may then be encoded by the 3D video transmitter. The 3D video transmitter may transmit the encoded base layer and the encoded enhancement layer as well as modification information associated with the modified enhancement layer to a 3D video receiver. The 3D video receiver may decode the transmitted encoded base layer and the transmitted encoded enhancement layer. The 3D video receiver may then modify the decoded enhancement layer, based on the transmitted modification information, so as to recover an original image of the enhancement layer of the 3D video frame.

摘要： A 3-dimensional (3D) video transmitter may be operable to encode a 3D video to generate a scalable video coding (SVC) base layer and a SVC enhancement layer. A first half-resolution view and a second half-resolution view of the 3D video in the SVC base layer may be packed in a first single frame. A first view such as a first high-resolution view and a second view such as a second high-resolution view of the 3D video in the SVC enhancement layer may be packed in a second single frame. The high-resolution may comprise a resolution that may be greater than half resolution. The first single frame in the SVC base layer may be used as a base-layer reference for the second single frame in the SVC enhancement layer for inter-layer prediction of spatial scalable coding.

摘要： A scalable encoder is enabled to crop received video content to form multiple resolution video layers comprising a base video layer and one or more enhancement video layers in different spatial resolutions. The base video layer and the one or more enhancement video layers are successively encoded and combined to generate composite video to be communicated to one or more video reception units. Coding information of the base video layer is utilized for encoding each of the one or more enhancement video layers. A video reception unit is operable to decode first the coded base video layer followed by the coded enhancement video layer based on device requirement. The video reception unit adjusts resolution of the decoded base video layer to improve video quality based on corresponding decoded enhancement video layers. A logo inserted at a desired position inside a cropping window is processed accordingly at the video reception unit.

摘要： Aspects of a method and system for PSI handling to improve channel change time. A MPEG-2 transport bitstream (TS) received using a MPEG-2 decoding system may comprise program specific information used for a desired program reception. In instances where signal acquisition or a channel change occurs, the received MPEG-2 TS may be gated or buffered for processing at least a portion of the PSI. The portion of the PSI in the received MPEG-2 TS may be detected and extracted from the buffered MPEG-2 TS during the PSI processing. After the PSI processing, the buffered MPEG-2 TS may be split into video, and/or audio, and/or data components based on the extracted PSI and may be decoded, accordingly. In instances where signal acquisition or a channel change does not occur, the TS buffering may be bypassed.

摘要： Systems, methods, and computer program products are described to determine and present proper decoding information to ensure correct decoding in digital video recording applications, and in other applications. For example, decoding and display of certain video units in a compressed bitstream may require the correct header information corresponding to the video unit to be also presented to a decoder along with the video unit. Since, however, the location of the corresponding header information in the compressed bitstream may not be adjacent to the video unit, the described header locating systems, methods, and computer program products may be used not only to index the header information in a bitstream, but also to determine when and what header information needs to be presented to the decoder.

摘要： One or more methods and systems of indexing an AVC video stream are presented. In one embodiment, the method comprises identifying one or more fields within a picture of an AVC video stream. In one embodiment, a field of the one or more fields indicates the beginning of each picture. In a second embodiment, a field of the one or more fields indicates a picture type of a picture. In a third embodiment, a field of the one or more fields indicates whether a picture is a reference or a non-reference picture. By determining that a picture is a non-reference picture, the picture may be discarded, thereby reducing the memory required to implement the indexing system while increasing the available memory size. In one embodiment, a system of indexing an AVC video stream comprises a control processor, a memory, and a set of instructions resident in the memory.

The first high-resolution view in the SVC enhancement layer may be an intra-layer reference for the second high-resolution view in the SVC enhancement layer for intra-layer prediction of temporal scalable coding.
