The 9-bit video input processor is a combination of a two-channel analog preprocessing circuit including source selection, anti-aliasing filter and ADC, an automatic clamp and gain control, a Clock Generation Circuit (CGC), a digital multi-standard decoder (PAL BGHI, PAL M, PAL N,combination PAL N, NTSC M, NTSC-Japan, NTSC N and SECAM), a brightness, contrast and saturation control circuit, a multi-standard VBI data slicer and a 27 MHz VBI data bypass; see Fig.1.
The pure 3.3 V CMOS circuit SAF7113H, analog front-end and digital video decoder, is a highly integrated circuit for desktop video applications. The decoder is based on the principle of line-locked clock decoding and is able to decode the colour of PAL, SECAM and NTSC signals into ITU-R BT.601 compatible colour component values. The SAF7113H accepts as analog inputs CVBS or S-video (Y/C) from TV or VTR sources. The circuit is I2C-bus controlled.
The integrated high performance multi-standard data slicer supports several VBI data standards:
· Teletext [WST (World Standard Teletext), CCST (Chinese teletext)] (625 lines)
· Teletext [US-WST, NABTS (North-American Broadcast Text System) and MOJI (Japanese teletext)] (525 lines)
· Closed caption [Europe, US (line 21)]
· Wide Screen Signalling (WSS)
· Video Programming Signal (VPS)
· Time codes (VITC EBU/SMPTE)
· HIGH-speed VBI data bypass for intercast application.
