Abstract:
A memory apparatus of a digital video signal for storing compressed video data, the compressed video data being derived from original video data representing a still image or a moving image and being compressed video data that represents components of three primary colors and luminance, the memory apparatus comprising:a memory portion for storing compressed video data obtained by adaptively selecting one of three primary color signals and a luminance signal; an address generation portion incorporating a counter for accessing the compressed video data stored in said memory portion; and a color restoring portion for restoring the stored compressed video data into said original video data, wherein said color restoring portion, said memory portion and said address generation portion are arranged on a single integrated circuit chip, wherein said counter counts pulses of a clock signal generated external to said chip and is reset by a memory control signal, and wherein upon restoration said compressed video data passes directly from said memory portion to said color restoring portion without passing through any elements external to said chip; whereby said color restoring portion is responsive to said clock signal.
