    摘要： The present invention facilitates reading in advance information on addresses where data of each reproduction path to be reproduced is stored. Clip AV stream 1 to Clip AV stream 3 of angles forming a multiangle are managed by PlayList#1 to PlayList#3 for the different angles. Each of PlayList#1 to PlayList#3 is divided by angle change points. Each of the divided reproducing sections corresponds to a PlayItem. Correspondences between source packet numbers and presentation time stamps of the angle change points are recorded in an EP_map. The present invention is applicable to DVD recording and reproducing apparatus, for example.

    摘要： The present invention enables a stable signal reproduction without overflow or underflow of a buffer in a decoder system even if a transmission bit rate is changed. In particular, when coding and transmitting a digital signal at a variable bit rate, a size of an encoder buffer for temporarily storing a coded signal in an encoder system is controlled according to a coding bit rate from a terminal. The encoder buffer has a code buffer to be used for rate control by the encoder system. The size of this code buffer is determined according to a reception buffer size of a decoder system supplied from a terminal, a maximum value of a coding bit rate supplied from a terminal, and a current bit rate.

    摘要： An apparatus and a method of encoding a digital signal with which a transmission buffer (an encoder buffer) does not overflow even if recording of a signal on a recording medium is temporarily inhibited attributable to, for example, an external shock or even if transmission of a signal by broadcast or communication is temporarily inhibited because of unsatisfactory state of communication. In a case where recording on an optical disk is temporarily inhibited and an output of data from an encoder is interrupted attributable to, for example, an external shock during an operation for recording a bit stream obtained by encoding a video signal on the optical disk, an encoding bit rate is lowered. Thus, a fact that the encoder buffer overflows can be prevented.

    摘要： A moving picture is encoded into groups of video image pictures with each frame composed of fields of different field polarities including a predetermined field polarity. The polarity of the first field of a series of frames to be encoded into a respective group of image pictures is set to the predetermined field polarity. Alternatively, the polarity of the first field of the series of frames may be identified by data transmitted with the encoded moving picture. The encoded moving picture is decoded at a decode start time designated when the first field in each respective group of image pictures is of the predetermined field polarity. Alternatively, the decode start time is generated on the basis of the data designating the field polarity of the first field. A computer-readable medium provides a medium on which the encoded moving picture is recorded and directs a computer to decode the encoded moving picture when the first image picture in each respective group of image pictures is an encoded field of the predetermined field polarity or, alternatively, when the field read from the medium is the first field as designated by designating data.
