1. processing an equipment for graph data, described equipment includes:

  • Coded data buffer, receive when coding and cushion the graph data including subtitle graphic data or navigation graphic data, described graph data includes page composition section, ending segment, one or more object display segment, and except described page composition section, the independent section including color table information outside described ending segment and the one or more object display segment, each object display segment includes graphic object data, size information and a PTS information, described page composition section includes defining the page composition information of the page composition of described graph data and when Drawing Object is output to the 2nd PTS information of display device,Decoder, decodes graph data;

    First buffer, according to the graphic object data in the graph data that object identifier storage is decoded by decoder;

    Page composition buffer, the page in the graph data that storage is decoded by decoder forms information;

    Second buffer, before graphic screen is output to display device, receives the Drawing Object used in composition diagram shaped screen in the graphic object data being stored in the first buffer, the graphic screen information of storage reference page composition information composition;

    Image controller, control the first buffer based on the page composition information forming buffer output from the page and select graphic object data necessary to composition diagram shaped screen, the graphic object data of selection is sent to the second buffer from the first buffer, and the page composition information forming buffer output from the page is sent to the second buffer, thus composition diagram shaped screen.
