GENERAL DESCRIPTION
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.
• 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)
The pure 3.3 V (5 V compatible) CMOS circuit SAA7113H,
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 CCIR-601 compatible colour
component values. The SAA7113H accepts as analog
inputs CVBS or S-video (Y/C) from TV or VTR sources.
The circuit is I2C-bus controlled.
• HIGH-speed VBI data bypass for intercast application.
