APPARATUS AND METHOD FOR GENERATING ON-SCREEN-DISPLAY MESSAGES USING FIELD DOUBLING |
摘要 |
An apparatus and concomitant method for generating an OSD message by constructing an OSD bitstream defining a single field of OSD data. The OSD 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 including various pointers, that are used to provide instructions as to the treatment of the OSD data. If a top field pointer and a bottom field pointer are set to an identical value in the OSD header, then the OSD unit will repeat each OSD line in the other field for an OSD region. |
