摘要： A moving picture encoding apparatus in which a minimum picture quality may be maintained even though the bitrate of an output encoded datastream is changed. A real-time distribution system for moving pictures 1 includes a frame rate conversion unit 11 for controlling the frame rate of input moving picture data, an encoding unit 12 for encoding moving picture data, having a controlled frame rate, in accordance with the MPEG-4, a frame rate calculating unit 16 for calculating a setting value of the frame rate, a transmission unit 13 for transmitting/receiving data over a network, and a receiving unit 14. The receiving unit 14 detects the state of communication on the network and, based on the detected state of communication on the network, calculates a target bitrate. The encoding unit 12 controls the bitrate of the MPEG-4 datastream responsive to this target bitrate. The frame rate calculating unit 16 estimates the picture quality based on the quantization scale of the encoding unit 12 and, in case of deterioration of the picture quality to more than a preset level, lowers the frame rate.

摘要： A reference frame block from a memory is supplied to a feature extraction circuit and a search frame block from a separate memory is supplied to a feature extraction circuit. Within the extraction circuits, the frame blocks are divided into minor blocks and the integration of all pixels for each minor block gives a matching element. A matching process with the matching elements from the extraction circuits provides a frame motion vector. Data division circuits divide the matching elements provided from the extraction circuits into odd- and even-field matching elements, and the matching process with the odd- and even-field matching elements provides odd- and even-field motion vectors. This eliminates the need for a feature extraction circuit when obtaining field matching elements.

摘要： A reference block is divided in the horizontal direction into small blocks, and is also divided in the vertical direction into small blocks. Feature values representing each of the small blocks formed from the reference block are obtained. Similarly, a check block is divided in the horizontal and vertical directions into small blocks and feature values representing the small blocks formed from the check block are obtained. The feature values in the horizontal direction of the reference and check blocks are compared, and the feature values in the vertical direction of the reference and check blocks are compared. The results of the two comparisons comprise an evaluation value by which the degree of matching of the reference and check blocks is evaluated. The check block is moved throughout a predetermined search range, and the process is repeated for each position of the check block. A motion vector is produced between the reference block and the check block position at which the check block best matches the reference block.

摘要： Initially, forward prediction reference block data which has been read out from a reference frame memory and retrieval block data which has been read out from a retrieval frame memory are used to detect forward prediction motion vector and its residual by a forward prediction motion detecting circuit to preserve (store) them into a forward prediction motion vector/residual preservation memory. Then, backward prediction reference block data which has been read out from the reference frame memory and retrieval block data which has been read out from the retrieval frame memory are used to detect, by a backward prediction motion detecting circuit, backward prediction motion vector and its residual, and to read out motion vector and its residual which have been preserved (stored) in the forward prediction motion vector/residual preservation memory to carry out encoding by using these motion vectors in both directions.
