Abstract
A video compression/expansion apparatus for a digital VCR, having an analog/digital converter, a memory, a video compression/expansion device, a compressed data memory, a modem, an error corrector, a deformatter, a first buffer, a second buffer and a digital/analog converter sequentially connected and electrically coupled to one another. According to the invention, the apparatus comprises a first logic control circuit for controlling the video compression/expansion device and the compressed data memory to transform compressed video data of 32 bits from the video compression/expansion device into four 8-bit data and alternately ,store the transformed four 8-bit data into first and second memories of the compressed data memory, a formatter for reading the compressed video data from the first and second memories and formatting the read video data at a fixed rate, an error correcting code generator for detecting an error of the compressed video data formatted by the formatter and generating an additional code for correction of the detected error, and a second logic control circuit responsive to clock and vertical synchronous signals from the deformatter for storing and rearranging compressed video data from the deformatter and controlling transmission of the rearranged video data to the video compression/expansion device.
