CASSETTE HAVING MEMORY AND CASSETTE PLAYER

摘要

PURPOSE:To realize high speed still picture communication by providing two types of cassettes, i.e., one cassette having a large capacity memory for storing both content information and still picture information and the other cassette having a small capacity memory for storing only the content information. CONSTITUTION:A non-volatile RAM 31 and a RAM controller 32 are built in a tape cassette 1. When the cassette 1 is loaded to a VTR 14, connecting terminals establish a communication path between a microcomputor 33 of the VTR 14 and the RAM controller 32. When a still picture display is requested, the microcomputor 33 delivers a command for reading the still picture data at high speed to the RAM controller 32 along with a start address and end address. The RAM controller 32 reads out a designated still picture data from the RAM 31 and transmits the still picture data to the VTR 14 at high communication rate. Upon finishing the communication, the RAM controller 32 returns back to low communication rate.
