Patent ID: 8149329

Claim:
An image processing system comprising: a receiving module, for receiving a composite signal carrying a first display data and a vertical blanking interval (VBI) data, the receiving module comprising: a video decoding unit, for decoding the first display data to generate a first image data; a VBI data decoding unit, for decoding the VBI data to generate a VBI image data; and a first converting unit, coupled to the VBI decoding unit, for converting the VBI image data into a color index data; a transmission interface, coupled to the receiving module, for transmitting the first image data and the color index data; and an image processing module, coupled to the transmission interface, the image processing module comprising: an image processing unit, for receiving the first image data to generate a second image data; a second converting unit, for receiving the color index data and generating the VBI image data according to the color index data; and an image mixing unit, coupled to the image processing unit and the second converting unit, for mixing the second image data and the VBI image data to generate a second display data.
