摘要： In the video data compression apparatus 1, the host computer 20 controls the operation of the constituent parts of the video data compression apparatus 1. Further, the host computer 20 receives the amount of data of the compressed video data generated by preliminarily compressing and coding the noncompressed video data VIN by the encoder 162 of the simplified two pass processing unit 16, the value of the direct current component (DC component) of the video data after the DCT processing, and the power value of the alternating current component (AC component) via a control signal C16 and calculates the difficulty of the pattern of the compressed video data based on these received values. Further, the host computer 20 allocates the target amount of data Tj of the compressed video data generated by the encoder 18 via the control signal C18 for every picture based on the calculated difficulty, sets the same in the quantization circuit 168 (FIG. 3) of the encoder 18, and adaptively controls the compression rate of the encoder 18 in units of pictures.

摘要： The present invention employs a statistical multiplexing method to enable suitable assignment of a target code rate to each program data. A controller (3) acquires encoding difficulty (Di) of each program from each of image encoders (2i). In accordance with an equation for transforming the encoding difficulty (Di) into a bit rate, the controller (3) calculates a temporary bit rate (Tmp_Ratei). Moreover, the controller (3) causes the sum of the target bit rates (Target_Ratei) to satisfy a predetermined allowable value by correcting the temporary bit rate (Tmp_Ratei) so as to determine a final target bit rate (Target_Ratei) and inputing the final target bit rate (Target_Ratei) to each of the image encoders (2i).

摘要： A video data compression apparatus with which compressed video data of suitable amounts of data can be produced and the time required for processing is short. The apparatus approximates a real difficulty data Dj indicating the difficulty of the pattern of each picture by the ME residual, flatness, and intra AC and further calculates the target amount of data Tj of the compressed video data from the approximated real difficulty data Dj. An encoder performs compression and coding so that the amount of data of the compressed video data becomes substantially the target amount of data Tj.

摘要： A residue code amount is calculated. A threshold act_thrsh corresponding to the residue code amount is obtained. A variable mb that designates a macro block is initialized to zero. The variable mb is compared with the total number of macro blocks. When the variable mb matches the total number of macro blocks, the process is completed. Otherwise, the rank of the activity information of the macro block designated by the variable mb is compared with the rank of the threshold act_thrsh. When the rank of the activity information is lower than the rank of the threshold act_thrsh, since there is a possibility of which q_scale can be decreased, q_scale is calculated with the activity information of the macro block mb and min_qq. q_scale of the macro block is subtracted from the total code amount. The subtracted resultant data is stored in a variable tmp. Thereafter, the variable tmp is compared with a target code amount GEN_TGT. When the variable tmp is equal to or smaller than the target code amount GEN_TGT, since the quantizing step can be fined down, the quantizing step of the macro block mb is decreased by one.

摘要： Encoding parameters of picture and higher layers of importance to a number of applications, and encoding parameters of slice and lower layers of no importance to all applications are converted into auxiliary packets inserted respectively into a V-blanking area and an H-blanking area of a video-data signal output by a history-information-multiplexing apparatus employed in a video-decoding system. On the other hand, a video-encoding system extracts back the auxiliary packets superposed on the V-blanking area and the H-blanking area from an input base-band video signal. As a result, a technique of superposing information on data can be changed in accordance with the importance of the information and required information can be fetched with ease.
