    摘要: A picture series is encoded so that a first type of decoder having only one frame memory and incapable of bi-directional decoding can decode the encoded bitstream, and a second type of decoder having multiple frame memories and capable of bi-directional decoding can decode the encoded bitstream to produce a higher quality decoded picture series. The encoded bitstream comprises three parallel channels of encoded picture data. The first channel includes every other picture and header information common to the second and third channels. The second channel includes the pictures not represented in the first channel and encoded by one of forward and backward predictive coding. The third channel includes the pictures not represented in the first channel and encoded by bi-directional predictive coding. The first type of decoder uses the first and second channels, while the second type of decoder uses the first and third channels.

    摘要: Only monitor side is caused to have decoding unit portion for bit stream, and reading unit portion for bit stream, decoding unit portion for bit stream and recording unit portion for bit stream are linked by digital network. Reproducing unit is caused to have a function to reproduce bit stream as it is, and recording unit is caused to have a function to record bit stream as it is. Bit stream reproducing unit and bit stream decoding unit of the monitor side, and such reproducing unit and bit stream recording unit are linked by high speed digital network. Thus, in the case where there is constructed a moving picture reproducing system such that a plurality of moving picture reproducing units are connected to one moving picture display unit to utilize source desired to see by selection of switch, cost can be reduced and degradation of the picture quality can be prevented.

    摘要: A picture type identifier, indicating one of intra-picture coding (an I-picture), forward or backward predictive coding (a P-picture) and bi-directionally predictive coding (a B-picture), is included with a picture signal when the signal is encoded and when the signal is decoded. Each of initial and subsequent encoding and decoding is a function of the included picture type.
