发明名称 Interframe encoding system having a buffer simulator
摘要 According to the present invention, an encoding system has an interframe encoder for interframe encoding of video signals to supply predictive encoded signals, and a scan converter for converting the predictive encoded signals into predictive encoded signals of a predetermined block structure. A code converter converts effective picture elements in the block-structured predictive encoded signals into variable length codes and ineffective picture elements therein into run length codes. A buffer memory not only stores the code-converted codes but also calculates their occupancy quantity. The present encoding system is further provided with a buffer simulator for calculating, on the basis of the predictive encoded signals and the code-converted signals, the quantity of information stored in the scan converter, an adder for adding simulated information and the buffer occupancy quantity, and a control circuit for controlling generation of interframe encoding information on the basis of the added signals.
