ENCODING TRANSMISSION APPARATUS OF PICTURE IMAGE |
摘要 |
A picture signal encoding and decoding apparatus which transmits a digital picture signal by encoding, and receives and decodes an incoming encoded signal comprises a configuration in which a condition not to make a receiving buffer overflow can be controlled on the transmitting side, and a plurality of quantizers are prepared and a proper quantizing characteristic is selected and used according to the sequence of transformed coefficients and the size of a motion vector. Therefore, it is not necessary to prepare a receiving buffer of a large capacity or a high speed decoding circuit, so that the apparatus can be manufactured at a low cost and the stability of operation is improved and also a signal can be compressed efficiently owing to the realization of quantization corresponding to a statistical characteristic of an input signal. |
