摘要：
TVs and other consumer electronics devices like VCRs and DVD players use on-screen display of messages. For display together with MPEG encoded video signals the picture content of an OSD text or graphic is stored in a non-volatile memory in a specific format: the OSD text or graphic content is divided into macroblock units and the OSD macroblock data are stored in MPEG encoded form in the memory. The OSD macroblocks to be displayed are then handled as a slice.
