摘要： When a quantized DCT coefficient and a quantization parameter are input from an entropy decoder, a controller outputs them to a switch and gives a load detector an instruction to detect system load. The load detector requests system load information from OS. If the system load is light, the load detector controls the switch to execute first inverse quantization of general load by a general processor and obtain a DCT coefficient. If the system load is heavy, the load detector controls the switch to execute second inverse quantization whose processing load is lighter than the first inverse quantization by a specific processor and obtain a DCT coefficient.

摘要： A communication terminal performs a discrete cosine transform and a quantization process in accordance with a selected coding mode so as to reduce loads caused by these processings and suppress degradation of picture quality. When performing coding of a moving picture inputted through a picture input part, a control part determines which coding mode among 4×4 intra prediction coding on a luminance signal, 16×16 intra prediction coding, intra prediction coding on a color-differential signal, and inter prediction coding is performed. In accordance with the selected coding mode, and in view of a predictive error, the processing content in the discrete cosine transform and the quantization process is switched.

摘要： An encoding section can perform moving picture compression processes by intra-coding and inter-coding. In accordance with an instruction from a code production amount control section, the encoding section divides an input VOP to MBs according to one of the moving picture compression processes by intra-coding and inter-coding, and subjects the divided MBs to encoding processing. A code production amount count section counts the code amount of a produced bit stream. A quantization scale mean value calculation section accumulates the quantization scale instructed by the code production amount control section, and calculates a mean value of the quantization scale for each VOP. The code production amount control section switches the encoding process to be carried out by the encoding section to the intra-coding process, on the basis of the code production amount, the mean value of the quantization scale and the frame skip number.

摘要： When stored stream data is deleted/edited, the packet sequence completely included in a deletion range is deleted from the stream data, and the stream data is segmented into first stream data before the start point of the deletion range and second stream data after the end point of the deletion range. First and second stream management data corresponding to the first and second stream data are generated. The index value of the packet including the start point of the deletion range is written in the header of the first stream management data. The index value of the packet including the end point of the deletion range is written in the header of the second stream management data. In addition, an index base value for correcting the index value is written in the header of the second stream management data.
