Abstract: A method and system are provided for synchronizing a digital video system that includes a transmitter, a receiver, and a decoder. A transport packet is received from the transmitter. At the start of receiving the transport packet, a system time clock timestamp is captured. A program clock reference timestamp is also obtained from the transport packet and is compared with the system time clock timestamp.

Abstract: A method and system are provided for processing a data transport stream. The transport stream is parsed to derive multiple elementary substreams, each of which includes a received media access control address. The received media access control address is then compared in hardware against several stored media access control addresses.

Abstract: A cache memory system in a computing system has a first cache module storing data, a second cache module storing data, and a controller writing data simultaneously to both the first and second cache modules. A second controller can be added to also write data simultaneously to both the first and second cache modules. In a single write cycle each controller requests access to both the first and second cache modules. Both cache modules send an acknowledgement of the cache request back to the controllers. Each controller in response to the acknowledgements from both of the cache modules simultaneously sends the same data to both cache modules. Both of the cache modules write the same data into cache in their respective cache modules.
