摘要： The present invention relates generally to the processing of multiple data streams with common resources. More particularly, this invention relates to a technique for time-multiplexed processing o, for example, multiple digital video programs. In one embodiment, an exemplary method provides for time-multiplexed processing of a set of digital streams includes storing each received packet in a random access memory. For each stream, the deadline for the arrival of the next packet at the receiver is determined and a priority based on the deadline is assigned. The stream with the highest assigned priority is identified as an identified stream. In some embodiments, the processing state of the identified stream is then restored. One or more packets of data corresponding to the identified stream are retrieved from random access memory to produce retrieved packets. The processing state is saved after the retrieved packets have been processed.

摘要： An advanced multiplexer designed and optimized for next generation on-demand video distribution is described. Features and capabilities include auto-discovery, channel-staggering and compatibility with static Virtual Channel Tables (VCTs). The multiplexer system facilitates auto-discovery by inserting identifiers into MPTSs (Multi-Program Transport Streams). These identifiers are echoed back to the multiplexer by the client set-top thereby indicating correspondence between modulators, service groups, and clients. When modulating multiple channels, FEC frames (Forward Error Correction frames) are staggered across channels to reduce correlation and clipping in the IFFT processor.

摘要： Methods are provided for inserting advertisements or the like and/or to perform grooming functions for a video, audio and/or data stream. Video programming is received in a network stream. Alternate content, such as advertisements, is received in content stream. The content stream is preconditioned to provide an entrance point therein for splicing the network stream to the content stream.

摘要： An SDRAM convolutional interleaver with two paths. Symbols are assigned to a given one of the two paths, then are sorted to minimize (to one) a number of breaks in a sequential Interleaver write address. After sorting, the symbols are stored staggered in SRAM and burst written to SDRAM. Before writing to SDRAM, data is accumulated for four symbols at a time, and the data is written four symbols wide to optimize SDRAM access time. 8 bit symbols are written 32 bits at a time to SDRAM.

摘要： The present invention provides a balanced video distribution system, as well as corresponding methods and apparatus, which utilize feedback from the channel multiplexers as well as rate estimation and predictive rate control. Packets of a video stream are received at an input buffer. A transmission deadline is determined for the packets. A fullness level of the input buffer is also determined. A future time at which said packets can be transmitted may be estimated based on the buffer fullness level. A bit rate of the video stream can be adjusted based on the estimated future time and the transmission deadline. For example, the bit rate may be adjusted in proportion to a difference between the estimated future time and the transmission deadline.

摘要： A video stream is transcoded to provide a plurality of primary profiles. Individual frames of the video stream have a Presentation Time Stamp (PTS). A PTS is used as a token to identify particular frames to be encoded as Instantaneous Decoder Refresh (IDR) frames in each profile. An IDR frame period is determined, indicative of a desired number of video frames between two IDR frames. An IDR frame is inserted into each profile every IDR frame period. The IDR frames of each profile are aligned with the same IDR frames of the other profiles. The PTS of each IDR frame in each profile is monitored. Upon determining that a PTS is out of alignment, the next PTS of the affected profile is aligned with the corresponding PTS of remaining profiles. Backup transcoders produce backup profiles that are maintained in alignment with each other and with the primary profiles.
