Abstract
Compression and decompression with high image quality is applied to reduce the data rate of transmitting an image results in high efficiency image transmission between TV and display device is presented. An LVDS bus is hooked between the TV side and display device with this invention of image compression apparatus in the TV side to reduce data rate and image decompression in the display device to reconstruct the image to be displayed.
Claims19
An apparatus of image data transmission between television subsystem and display subsystem, comprising:
- a TV chipset unit functioning at least features as program tuning and selection, video and audio decompression, and in the video feature:
- de-interlacing and frame rate conversion from the received number of field or frame to the predetermined frame rate per second, constructing the frame images by referring to the accessed adjacent filed/frame pixels;
- an image compression unit embedded in the TV side reduces the data rate of the decompressed and processed video images;
- a pixel bus with transmission unit embedded in the TV side to submit the compressed image to the display device;
- a pixel bus with receiving unit embedded in the side of display device to receive the compressed image;
- An image decompression unit embedded in the display device reconstructs the received images previously compressed in the TV side and temporarily saves the decompressed image into a frame buffer storage device and waits for the predetermined right timing to be sent to the display unit;
- and
- a display unit with pixel driving unit for accurately driving out the corresponding pixels to the predetermined points of a display unit.

- a pixel bus with transmission unit embedded in the TV side to submit the decompressed and processed images to the display device;
- a pixel bus with receiving unit embedded in the side of display device to receive the decompressed and processed images sent from the TV side;
- a control unit in the display device determines the timing of presenting the corresponding pixels to the display driver with an image compression and decompression unit, compressing the image before temporarily saving to the pixel buffer and decompressing the frame pixels accessed from the temporary pixel buffer before sending to the display driving devices;
- and
- a display unit with pixel driving devices for accurately driving out the corresponding pixels to the predetermined points of the display unit.

- a pixel bus with receiving unit embedded in the side of display device to receive the decompressed and processed images sent from the TV side;
- a control unit in the display device determines the timing of presenting the corresponding pixels to the display driver with an image compression unit which compresses the image before temporarily saving to the pixel buffer;
- and
- a display unit with pixel driving devices with image decompression unit embedded in each corresponding display driving device to decompressing the corresponding lines of pixels for accurately driving out the corresponding reconstructed pixels to the predetermined points of the display unit.
