摘要： A system and method is provided for generating and using multiple synchronized local program timestamps in a media processing system. The system includes an input processor, one or more local timestamp insertion modules, one or more parsers, and an input buffer. Each local program timestamp module includes a clock reference recovery module, a local program clock synchronized to the system time clock of a program source, and a timestamp generator. The system also includes one or more processing modules such as record modules, transmission modules, and display modules. When a data packet is received by the media processing system, the local timestamp insertion module appends a timestamp to the data packet. The timestamp is based on the synchronized local program clock for the program associated with the data packet. The processing modules utilize the synchronized local timestamps and their associated local program clock in a variety of applications.

摘要： In data processing applications, a method and system for a single data buffer and a data buffer controller for merging rate-smoothing and burst buffering functionalities to process incoming data streams in integrated circuits is provided. The data buffer controller may comprise a data processor and an output controller. The incoming data stream may be received by the single data buffer prior to processing or may be received by a data processor directly. The data processor processes data blocks from the incoming data, transfers the processed data blocks into the single data buffer, and notifies the output controller that the data blocks have been transferred to the single data buffer. The output controller selects data blocks to assemble a data block burst, arbitrates access to a memory bus with a bus controller, and notifies the single data buffer to transfer the data block burst when access has been granted.

摘要： Embodiments of the present invention significantly decrease the processing requirements as well as the cost of digital television receivers. In an embodiment, processing requirements of both hardware and software components in digital television receivers are lowered by generating the channel map without regard to channel map information present in a Virtual Channel Table (VCT). In another embodiment, significant recurring portions of an ATSC signal can be neglected with no processing power, cost, and time spent thereon. In another embodiment, processing typically used to process channel map information contained in the VCT portion of the ATSC signal is freed and may instead be used to process other information, thereby enabling further enhancements and features in digital television services.
