Abstract: The present invention relates to a video decoder having means for compressing reference frame data (6) using a scalable compression method. The video decoder further having buffer means (8) for intermediate storing of at least the vertical aperture (range) of motion vectors plus one row (slice) of macro blocks in lines of video per reference frame. Further it includes means for decompressing reference frame data (7) for enabling means for motion compensation (10) of said decoder to reconstruct vector predicted pictures and macro blocks utilizing said decompressed reference frame data. The present invention also relates to a method to be implemented by such a video decoder.

Abstract: A method of decoding video data (ENC(VI)) in a video decoder (50) for regenerating sequence of images (VO) is described. The method involves arranging for the decoder (50) to include processing means (70) coupled to data memory (60). Moreover, the method involves: (a) receiving and then storing the video data (ENC(VI)) including anchor picture data; (b) processing the video data to generate luminance and chrominance block data; (c) processing the luminance and chrominance data to generate corresponding macroblock data (130); and (d) applying motion compensation to generate from the macroblock data (130) and one or more anchor pictures the sequence of decoded images (VO).

Abstract: A system (1) and method for extracting and detecting fingerprints and attaching an associated action to a first fingerprint. A signal comprising a data stream is captured by a fingerprint extractor (9). The fingerprint extractor (9) will extract the first fingerprint of user specified data within the data. An input device (20) is adapted to accept a first command to extract the first fingerprint and accept a second command to attach an associated action to the first fingerprint. A memory device (14) is adapted to store the first fingerprint and the associated action. A fingerprint detector (4) is adapted to capture the signal comprising the data stream, continuously extract a plurality of fingerprints from the data stream, and compare the plurality of fingerprints to the first fingerprint for a match. A control device (7) is adapted to execute the associated action upon detection of a match.

Abstract: The problem of increased power consumption due to infrared remote control false alarm handling by a main TV controller (88) and power dissipation due to leakage current is addressed by fully delegating standby tasks to a low power delegate controller (90) with minimal local resources and having high performance and many dissipating system parts disabled. In low power standby mode the delegate controller (90) validates autonomously a remote control (42) command, a keypad (34) press, a timer alarm, and external interrupt etc. The TV system is powered up only when a command is valid. Use of a switched power supply voltage (70) reduces the leakage current problem. The delegate micro-controller is included on the same integrated circuit (IC) package as the main micro-controller, advantageously on the same IC die.
