摘要： An encoding apparatus adds delay time information DTI indicating initial delay time i_d and delay time d of each group data to a position to be read prior to frame data by a decoding apparatus in the group data of encoding stream data DBI and transmits the same to the decoding apparatus 3. Namely, the encoding apparatus does not transmit initial offset delay time i_of to the decoding apparatus 3. The encoding apparatus starts to read and transmit the encoding stream data DBI from a transmission buffer at a predetermined bit rate R at timing designated by the initial offset delay time i_of.

摘要： Video signal transmitting system in which digital video signal are divided into groups of predetermined frames. Digital video signals of at least one frame are intraframe coded and then transmitted. Remaining digital video signals are interframe coded with reference to the intraframe coded digital video signals, and intraframe coded digital video signals of a subsequent group of frames and are then transmitted. A motion vector from a predetermined reference frame is detected. Video signals are interframe coded by the motion vector to transmit the video signals. A motion vector from a first frame which is a plurality of frames away from the reference frame is converted to a motion vector for a one frame interval between the reference frame and the first frame. The motion vector is optimized, and is then transmitted.

摘要： In connection with compression-coding of video signals on the basis of inter-frame correlation, a single reference table is used for variable length encoding of inter-frame motion vectors established on the basis of various motion vector value ranges and degrees of accuracy. A reference table is provided for variable length encoding motion vectors based on a particular value range and degree of accuracy. In order to use the same table for motion vectors based on a larger value range than that for which the table was designed, the value of a motion vector to be encoded is divided to form a quotient and a remainder. An addition bit code is formed on the basis of the remainder and is appended to a variable length code which corresponds in the reference table to the quotient so that a variable length code value is formed for the motion vector based on the larger range. As to motion vectors based on a finer degree of accuracy than was provided for in the reference table, the motion vector value is multiplied by an appropriate factor and the resulting product is used to obtain a corresponding variable length code value from the reference table. Decoding is performed using the same table and by means of decoding operations that are the inverse of the encoding operations.

摘要： A video image data decoding apparatus includes a pair of buffer memories for storing decoded intra coded picture data or forward prediction coded picture data, a switch circuit for selecting either the decoded intra coded picture data or forward prediction coded picture data to be sequentially stored in the pair of buffer memories, and a generating circuit utilizing picture data stored in one of the pair of buffer memories for generating picture data to be stored into another buffer memory and also utilizing picture data stored in one buffer memory for generating picture data to be newly stored again into the same buffer memory. The generating circuit performs motion compensation by utilizing picture data stored in one buffer memory for generating picture data to be stored into another buffer memory.
