♦ Video Signal Conversion
Video reconstruction module converts the multiplexed data (ITU-R. BT601 Y/Cb/Cr) to the interlace
format of NTSC-M, PAL-M, PAL-B,D,G,H,I,N and other formats (ex. NTSC-4.43 and PAL60). The video
reconstruction format, the line number, the color encode way(NTSC or PAL) and the frequency of Color
Sub-carrier is specified by [Video Process 1 register(01H)]. (cf. Burst Signal Table) The frequency and the
phase of Color Sub-carrier are also adjustable by [Sub C. Freq. register(06H)] and [Sub C. Phase
register(07H)]. The Sub-carrier has a free-running mode and a reset-mode. In the reset-mode, the
Sub-carrier is reset automatically to the initial phase for every 4 fields (NTSC) or 8 fields (PAL).
