Picture communication equipment

Abstract

Abstract PURPOSE:To reduce the entire transmission time in response to the information compression rate without losing the effect of information compression by optimizing the quantity of information stored in a buffer memory in response to the compressed quantity of received picture information automatically. CONSTITUTION:Picture information outputted from a picture information generating source 11 is compressed by a compression means 12 in a sender side equipment 10 and stored sequentially in a buffer memory 13. Moreover, an information quantity notice means 16 integrates the quantity of information and the integrated information quantity is informed to a receiver side equipment 20 ahead the transmission every time the compressed picture information by one page is sent. Based on the informed information quantity, the buffer memory 22 calculates the time difference from the storage of the received picture information till the picture recorder 24 starts recording at the receiver side. Then after the picture information is initiated to be stored in the memory 22 and the said time difference elapses, the recording from the memory 22 to the picture recorder 24 is started.
