上の問題となっていた。However, since the VTR is a serial access type recording, recording cannot be performed at the same time while the video is reproduced. Therefore, during the playback time, continuous monitoring video recording will be interrupted, and part of the recording will be lost, so past images cannot be played back while recording in real time. It was a system performance problem.

Both writing and reading are performed in units of one block of storage area indicated by the number of addresses per unit time as described above.
For the reading, the compressed data stored in, for example, three addresses a, b, c are continuously read in the first unit time, and the next three unit addresses are read from the next three addresses. . In the writing, for example, the first unit time is continuously written to three addresses h, i, j, etc., and the next unit time is continuously written to the next three addresses. In the above example, the number of addresses is 1k and the storage area is one block. If the memory unit 3 is required to have a higher transfer rate, one of the methods is to configure the memory so that memory access (writing or reading) is performed in parallel, for example, 4 bytes at a time. The transfer rate may be increased four times as compared with the case of accessing in units of 1 byte.
