摘要： In the speckled broadcasting of HDTV and SDTV, an encoding transmitting apparatus and a decoding receiving apparatus can perform a parallel multichannel transmission and reception of SDTV with a simple construction. When an HDTV video signal is encoded and decoded, each of the transmission buffer 30 and the reception buffer 80 is used as a single buffer. On the other hand, when a plurality of SDTV video signals are encoded and decoded, the transmission buffer 30 and the reception buffer 80 are divided into the number of SDTV video signals to use them as a plurality of divided transmission buffers and a plurality of divided reception buffers, so as to perform a encoding and decoding processing.

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： 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.

摘要： An improvement in solving the problem of the wraparound state. A moving image is coded in an encoder. The resulting coded data is supplied to a buffer through a multiplexor and stored in the buffer. The address used for storing the coded data in the buffer is generated in an address controller. The coded data supplied from the encoder is combined with the address in the multiplexor in a multiplexing manner.

摘要： A user interface system comprises a server having a scene description converting device for converting scene description containing input user interaction into converted scene description while leaving parts containing the user interaction and a scene description decoding device for decoding converted scene description into decoded scene description, a remote terminal having a scene description decoding device for decoding scene description and converted scene description sent from the server and a display device for displaying decoded scenes and a user input device for receiving user input according to this display, and a display terminal for displaying decoded scenes sent from the server. Thus, decoding can be enabled at terminals having inferior decoding capabilities and display capabilities.
