专利汇可以提供Generating information control system for inter-frame forecasting encoder专利检索,专利查询,专利分析的服务。并且PURPOSE: To effectively utilize a transmission line buffer memory by providing a memory to compensate the delay quantity of an entropy encoder circuit, means to generate a warning signal and means to prohibit to write the output signal of the memory to a frame memory.
CONSTITUTION: An entropy encoder circuit 7 receives a quantization forecast error signal 3a and outputs an encoded signal 7a. When a warning signal 9a is received, however, the quantized forecast error signal 3a is encoded as zero until it is started to encode the next encoding frame. Then, the encoded signal 7a is written to a transmission line buffer memory 8 and speed is made smooth. Afterwards, the signal is outputted from an output terminal 10. When the transmission line buffer memory nearly approaches to overflow, the forecast error signal is made zero in an entropy encoding part and the writing of the frame memory is controlled. Thus, the transmission line buffer memory can be effectively utilized.
