Abstract
A memory apparatus of a digital video signal for storing color compressed video data is disclosed, the color compressed video data being compressed video data that represents components of three primary colors, the memory apparatus comprising a memory portion for storing the color compressed video data and a color restoring portion for restoring the color compressed video data into original video data, wherein said color restoring portion is disposed on a semiconductor substrate that is used in common with said memory portion.
Claims9
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.
A memory apparatus of a digital video signal for storing input data that represents video components of three primary colors and luminance, the memory apparatus comprising:
- a memory portion for storing input data that has been obtained by adaptively selecting one of three primary color signals and a luminance signal;
- an address generation portion incorporating a counter for accessing the input data stored in said memory portion;
- and
- a restoring portion for restoring the original video data by decoding said stored input data,
- wherein said 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 input data passes directly from said memory portion to said restoring portion without passing through any elements external to said chip;
- whereby said restoring portion is responsive to said clock signal.
A memory apparatus of a digital video signal for storing input data, the input data being compressed video data and the compressed video data being derived from original video data representing a still image or a moving image and representing components of three primary colors and luminance, the memory apparatus comprising:
- a memory portion for storing input 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 input data stored in said memory portion;
- and
- a restoring portion for restoring the original video data by decompressing the stored input data,
- wherein said 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 input data passes directly from said memory portion to said restoring portion without passing through any elements external to said chip;
- whereby said restoring portion is responsive to said clock signal.
