APPARATUS AND METHOD FOR GENERATING ON-SCREEN-DISPLAY MESSAGES USING ONE-BIT PIXELS |
摘要 |
An apparatus and concomitant method for generating an OSD message by constructing an OSD bitstream having a plurality of "one-bit" pixels. The OS D bitstream contains an OSD header and OSD data. An OSD unit retrieves pixel control information from the OSD header which is programmed by a processor of a decoding/displaying system. The OSD header contains information that is used to program a color palette of the OSD unit and to provide instructions as to the treatment of the OSD data. If the "Compressed Pixel Mode" is enabled in the OSD header, then the OSD unit will treat each bit of the OSD data as a "one-bit" pixel. |
