摘要： A video signal recording apparatus is capable of compressing the amount of information of a video signal sequentially containing a plurality of pictures correlated to one another. In this compression, the video signal recording apparatus can selectively assume an intrapicture coding mode for executing compression by using only a correlation within each of pictures of the video signal and an interpicture coding mode for executing compression by using a correlation between a plurality of pictures of the video signal. When a video signal the amount of information of which is compressed is to be recorded on a recording medium, the video signal recording apparatus starts recording with a video signal compressed in the intrapicture coding mode. When a video signal compressed by variable-length coding is to be recorded while sequentially forming a multiplicity of tracks on a recording medium, the video signal recording apparatus begins recording a picture to be recorded immediately after the start of recording, at the forefront of the tracks.

摘要： An MPEG2 encoded signal comprising intra-encoded pictures I and inter-encoded pictures B is decoded (70-74) to baseband and re-encoded (76) to I-pictures. The quantisation levels Q.sub.v and the motion vectors M.sub.v of the B pictures are retained unchanged and maintained in association with the corresponding pictures re-encoded as I-pictures. The I-pictures can be decoded to baseband, processed, and re-encoded as I-pictures without degradation. The I-pictures can then be re-encoded back to e.g. I, B pictures with minimal degradation. Alternatively, some of the I-pictures are decoded and converted to B pictures retaining unchanged the quantisation levels thereof.

摘要： A multimedia optical disc is provided. The multimedia optical disc includes a data area and a management information area. The data area stores a plurality pieces of video data. The management information area stores a channel table in which a plurality of logical channel numbers are respectively related to a plurality of physical channel numbers for each piece of video data. A piece of moving picture data and a plurality pieces of sub-data are interleaved in each piece of video data. The sub-data is either of audio data and sub-picture data as still pictures. The logical channel numbers are shared by pieces of video data. The physical channel numbers are used to physically identify the plurality pieces of sub-data. With this construction, it is possible to manage sub-data even when the sub-data is dealt with by a plurality pieces of video data.

摘要： The coded image information is divided into first and second groups in the same frame, and decoding information is added to the divided coded image information of the first and second groups. The first group of divided coded image information with the decoding information added in the recording unit is recorded in a first recording area of a recording medium, and the second group of divided coded image information with the decoding information added in the recording unit is recorded in a second recording area of the recording medium. It is determined whether a start-of-record frame or end-of-record frame of coded image information to be recorded agrees with an intermediate frame in the recording unit of coded image information recorded on the recording medium, in an editing recording mode in which the coded image information is recorded in superposed relation to the areas of the recording medium in which the first group of divided coded image information and the second group of divided coded image information are recorded.
