Abstract
A video processing method utilized in a video data processing device for processing video data is disclosed. The video data includes at least a first video data set, and the video data processing device has a memory and a video decoder. The method includes utilizing the video decoder to decode the video data for generating a display data set, driving the video decoder to select a specific video data set from the first video data set wherein the display data set does not have display data corresponding to the specific video data set, and utilizing the memory to store the display data.
Claims16
A video data processing apparatus for processing video data, the video data comprising a first video data set for driving a displayer to display a first picture, and the video data processing apparatus comprising:
- a memory, comprising a first memory block and a second memory block, wherein the first memory block stores the first video data set;
- a video decoder, coupled to the memory, for decoding the video data from the first memory block to generate and output a display data set, wherein the video decoder selects a specific video data set out of the first video data set stored in the first memory block according to a display area of the displayer, and the display data set does not comprise display data corresponding to the specific data set;
- and
- wherein the display data set outputted by the video decoder is stored in the second memory block of the memory.
A method for processing a video data, the video data comprising a first video data set for driving a displayer to display a first picture, the method comprising:
- utilizing a memory to store the video data set into a first memory block of the memory;
- selecting a specific video data set out of the first video data set stored in the first memory block according to a display area of the displayer;
- utilizing a video decoder to decode the video data from the first memory block to generate and output a display data set, wherein the display data set does not comprise display data corresponding to the specific data set;
- and
- utilizing the memory to store the display data set outputted by the video decoder into a second memory block of the memory.
