Abstract: A fine-grain scalable video data apparatus, system, method and data structure is disclosed. An encoder (110) for encoding input video data as minimum bitrate macroblock data to produce DCT data having DCT coefficients representing a minimum bitrate version of the macroblock data. The encoder (110) also encodes the input video data as intermediate bitrate macroblock data to produce DCT data having DCT coefficients representing an intermediate bitrate version of the macroblock data. An adaptive motion compensator (132) (whether incorporated within the encoder or externally) communicates with the encoder for predicting whether a decoded version of the intermediate bitrate macroblock data has an accumulated predicted error frame energy exceeding a maximum threshold (228).

Abstract: A minimal level of interoperability for exchanging audio/video (A/V) content and associated control between common consumer electronic (CE) devices is defined. This interoperability is based on the IEEE 1394 serial bus for the physical and link layers and makes use of AV/C or CAL as the control language. This invention provides for reducing the number of remote controls that the user might need by allowing remote control commands to always be received by a controlling device (e.g., digital television) and then routed to the appropriate peripheral device (e.g. digital VCR) after translation into a universal format.

Abstract: A fine-grain scalable (FGS) encoder, decoder, and corresponding methods are disclosed which utilize conditional replacement for selecting between a base layer prediction and an enhancement layer prediction. Processes include: encoding data as a plurality of discrete cosine transform (“DCT”) coefficients for each of a base layer and an enhancement layer, a first conditional replacement (“CR”) portion in signal communication with the encoder for selecting between a base layer prediction and enhancement layer prediction for each DCT coefficient of the enhancement layer to increase coding efficiency, receiving encoded DCT data from encoder, decoding the encoded DCT data to produce reconstructed data responsive to the selected prediction, and a second CR portion in signal communication with the decoder for selecting between the base layer prediction and the enhancement layer prediction for each DCT coefficient of the enhancement layer to reduce prediction drift.
