摘要： An encoder considers a frame representing a picture as comprised of areas. For each area, the encoder decides which of frame-based or field-based orthogonal transformation will be most efficient at reducing spatial redundancy in that area. For each area, the encoder decides which of frame-based or field-based predictive encoding will be most efficient at reducing temporal redundancy in that area. The encoder encodes each area of the picture frame using the most efficient orthogonal transformation technique and using the most efficient predictive encoding technique to produce an encoded signal. A decoder decodes the encoded signal. The encoded signal is recorded on a recording medium, transmitted over a transmission channel, or broadcast.

摘要： The invention provides a recording and/or reproduction apparatus and a recording and/or reproduction method by which information can be recorded or reproduced accurately onto or from any of a plurality of record layers of an optical disk. In the recording and/or reproduction method, after an optical disk is started, an optimum focus offset position for a predetermined record layer of the optical disk is searched for. This searching is performed by varying an offset value stepwise and searching for an offset value with which the amplitude of a tracking error signal exhibits a maximum value. After an optimum focus offset position is searched out, the value of it is stored. Similar processing is performed also for any other record layer. When an instruction to reproduce a predetermined record layer is developed in step, focus jumping to the record layer is performed. Then, an optimum focus offset value searched out and stored in advance is read out and added to a focus error signal.

摘要： A motion detecting apparatus in which when pixels within a search range formed of a predetermined number of pixels and pixels within a reference data block the number of which is smaller than the predetermined number of pixels in the search range, are compared on the basis of the arrangement state thereof, a processing circuit processes sums of difference absolute values of respective pixels within the reference data block and corresponding pixels within the search range formed at every search range, to thereby detect a motion state on the basis of the sums. Respective pixels within the search range are input to the processing circuit at a set time and pixels within the search range are input to the processing circuit at the set time, thereby being sequentially processed with corresponding pixels within the data block.

摘要： The invention provides a recording and/or reproduction apparatus for a record medium in the form of a disk by which the necessity for adjustment of an inclination of a head with respect to a disk upon production of the apparatus is eliminated and correct reproduction of data can be assured irrespective of a variation with respect to time. A control circuit controls an offset generation circuit to generate a predetermined offset signal. A skew servo circuit drives a skew motor in response to the offset signal to adjust the relative angle of an optical head with respect to an optical disk to a predetermined angle. A level detection circuit detects the amplitude of the tracking error signal then and outputs it to the control circuit. The control circuit adjusts the offset signal to be outputted from the offset generation circuit so that the amplitude of the tracking error signal may be maximum.
