摘要： PROBLEM TO BE SOLVED: To overcome disadvantages in conventional compression systems of MPEG or those similar to MPEG, by limiting the minimum values of MPEG quantization scale factors or equivalents of non MPEG systems through incorporation of a circuit and/or software code, and not directly limiting bit rates of compressed video signals. SOLUTION: In a compression system including a quantizer 14 for quantifying a matrix of coefficients according to a matrix of quantization values, a quantization matrix is modified in response to occupancy of a rate buffer 24 to provide quantization scale factors 26. By incorporating an apparatus to impose limitation 28 on the minimum values of the quantization scale factors input to the quantization matrix, a significant channel capacity can be salvaged without significant loss of image quality.

摘要： PROBLEM TO BE SOLVED: To provide an adaptive trellis decoder (24) which seamlessly switches between multiple operational modes. SOLUTION: The trellis decoder employs a code sequence detection system (40) that detects codes in input interleaved packet data. The code sequence detection system processes video data in the form of groups of interleaved trellis encoded data packets and includes a traceback network (47) that identifies a sequence of antecedent trellis states, in accordance with a state transition trellis. The traceback network identifies the antecedent states for collocated interleaved packets in response to decision data associated with trellis state transitions. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an adaptive scan format converter in a transmitter, and to automatically convert a received scanning format to a desirable format so as to display it in an auxiliary image display device in a receiver, as a function to decide which format is desirable to encoding and transmission through an output channel.

A received sequential signal is transferred to the display device without performing a format conversion. As an automatic scanning conversion is continuously performed, the conversion, for example, between a television program material and an interlace commercial material is performed without artifact and basically invisible to an observer.
