ABSTRACT:
The present invention relates to methods and devices for compression and multi-screen process of digital video signals by multi-thread scaling. The method comprises. (a) a step to scale the resolutions of digital video signals; and (b) a step to compress or process for multi-screens the scaled digital video signals. The device comprises: multi-channel analog/digital converters, a compression FIFO; a multi-screen FIFO; a CPU which initializes each channel's analog/digital converter, and a video processor which transmits to the video memory. The processor for compression/multi-screen process may conduct the compression and multi-screen process sequentially from the compression FIFO and the multi-screen FIFO depending on the even/odd fields of the signals Thus, the method and device uses N analog/digital converters for the same N channels while providing the same function as the conventional system.
