A video signal processing method applied for a TV system is disclosed. In this method, the received video signal is processed by a video decoding process, and then the decoded video signal is processed by a de-interlacing process. A still or corresponsively still image signal is generated and blended with the de-interlaced video signal to generate a blended signal which is displayed to make sure the OSD information can always be shown at the top layer of the screen of the LCD panel.

Television system and video processing method

A method and a device for processing digital image are provided. The processing method comprises a coding process and a decoding process. The coding process comprises the steps of: obtaining the background data of an image data; separating the foreground data from the image data according to the background data; generating a file header; coding and compressing the foreground data as data packets according to a compression type; and generating a coded image file by combining the file header and the data packets. Each packet contains the information about the foreground data, packet size and location of the foreground data. The file header contains the information about the background data, images width, image height, image type, coding type, and compression type. The decoding process comprises the steps of reading the coded image file; obtaining the file header from the image data; decompressing each compressed foreground data of the data packet according to the compression type to generate the foreground data; forming the original image data by writing the foreground data into the locations stored in the data packet and writing the background data into the background location which are not filled with the foreground data.
