The invention discloses a system for processing ultralong caption rendering, which is characterized in that includes determining module, used to determine the value of the memory size and N play according to the size of the screen and the caption data; distribution module for caption image memory allocation; adjustment module, used to adjust the memory image content subtitles in storage, the memory is always stored on screen display area and caption image to be displayed caption image. The invention adopts a plurality of memory blocks of fixed size for the caption image memory is allocated, the large memory needed for ultralong caption can be achieved by a plurality of memory blocks to update the stored image; image are stored in different memory blocks, reduce the image rendering time, the real-time dynamic subtitles broadcast smoothly.
