APPARATUS AND METHOD FOR GENERATING ON-SCREEN-DISPLAY MESSAGES USING STORED BITSTREAMS |
摘要 |
<p>An apparatus and concomitant method for constructing a valid OSD message bitstream from a plurality of stored character bitstreams. Each character of the OSD font set is initially scaled into a fixed block size, e.g., a block size of 16 x 16 pixels. Each character is then encoded into a "character bitstream" using the intra macroblock coding syntax. The character bitstream is stored within a storage medium. When a frame of OSD messages needs to be encoded, the character bitstreams are read from the storage medium and cascaded to form a valid OSD message bitstream which represents the frame of OSD messages.</p> |
