摘要： In one embodiment, bridges in a computer network maintain a per-port mapping table for each of its ports, where each mapping table maps, for each virtual connection (of more than 4K) at a respective port, i) frame encapsulation fields that uniquely identify a particular virtual connection at the respective port to ii) a particular multiple spanning tree (MST) instance. The bridges may then compute a checksum of a particular mapping table for a particular port, and share the checksum with a corresponding port interconnected with the particular port (e.g., of another bridge). Upon determining that the mapping tables at the corresponding ports match in response to the checksums matching, frames may then be forwarded between the ports based on the particular mapping table.

摘要： A system and method of processing a digital video signal for display on a display device, includes decoding an encoded digital video signal to produce a decoded digital video signal having a video source format; extracting coding information from the encoded digital video signal; executing a video quality improvement algorithm on the decoded digital video signal having the video source format using the extracted coding information, to produce a processed decoded digital video signal having the video source format; and converting the processed decoded digital video signal from the video source format to a video display format suitable for display on the display device. The system and method enhance the quality and/or reduce video artifacts in a video signal after it is decoded and prior to display on a display device.

摘要： A MPEG-2 decoder receives an MPEG-2 video stream containing discrete cosine transform (DCT) blocks and generates linear contrast enhanced DCT blocks applied to an inverse DCT processor contained therein. Preferably, the MPEG-2 decoder includes a linear contrast enhancement processor receiving the DCT blocks and generating the linear contrast enhanced DCT blocks, and the inverse DCT processor coupled to the linear contrast enhancement processor. Additionally, the MPEG-2 decoder can include a microprocessor which controls the linear contrast enhancement processor and the inverse DCT processor. A method and a memory containing computer readable instructions permitting the microprocessor to control the MPEG-2 decoder are also described.
