摘要： To allow a finer quantization control according to the property of an image within a macroblock, quantization parameter values are allowed to be changed in units of sub-blocks equal to or smaller than the macroblock in a similar manner as in motion compensation and orthogonal transform processes. A finer-tuned quantization control is performed, for example, by selecting fine and coarse quantization parameters respectively for corresponding sub-blocks if a plurality of images having different properties coexist within the macroblock.

摘要： An encoding method, which achieves encoding efficiency, and good picture quality encoding even when there exists a picture in which a scene change occurs within an interlaced frame, is provided. A moving pictures encoding method treats a frame of interlaced image input signals as a picture, and performs prediction and encoding for this picture in macro-block units from a picture of both a forward picture, which is temporally in the past, and a backward picture, which is in the future. When performing encoding in accordance with the above-mentioned bi-directional picture, the method performs inter-field motion prediction, which treats as a unit a field, which divides each picture in macro-blocks into either odd numbers or even numbers of pixel scanning lines of this frame, and as a prediction mode, selectively switches in picture units between using prediction from a forward field motion vector for one field, and using prediction from a backward field motion vector for the other field, generates a predictive picture corresponding to the selected prediction mode, and encodes the input signal using the generated predictive picture.

摘要： A multi-point conference system includes a plurality of conference terminal devices coupled to each other, image information and voice information being transmitted among the plurality of conference terminal devices so that users of the plurality of conference terminal devices are in conference with each other. A coding process unit of a transmission side conference terminal device codes image information by switching an intra-frame coding operation and an interframe coding operation and transmit coded image information when the each of the plurality of terminal devices is specified by a speaker specifying information item. The coding process unit of the transmission side conference terminal device which is specified again by a speaker identifying information item codes image information by an interframe coding operation starting from a head frame. A decoding process unit of a receiving side conference terminal device which receives the coded information from the transmission side conference terminal device decodes the coded information by the decoding operation corresponding to the interframe-coding operation using reference image information last stored in a frame memory portion corresponding to the transmission side conference terminal device.
