3 / 147 page  2004 Mar 03 3 Philips Semiconductors Product specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI data slicer and high performance scaler SAA7114 1 FEATURES 1.1 Video decoder • Six analog inputs, internal analog source selectors, e.g. 6 × CVBS or (2 × Y/C and 2 × CVBS) or (1 × Y/C and 4 × CVBS) • Two analog preprocessing channels in differential CMOS style inclusive built-in analog anti-alias filters • Fully programmable static gain or Automatic Gain Control (AGC) for the selected CVBS or Y/C channel • Automatic Clamp Control (ACC) for CVBS, Y and C • Switchable white peak control • Two 9-bit video CMOS Analog-to-Digital Converters (ADCs), digitized CVBS or Y/C signals are available on the expansion port • On-chip line-locked clock generation in accordance with “ITU 601” • Digital PLL for synchronization and clock generation from all standards and non-standard video sources e.g. consumer grade VTR • Requires only one crystal (32.11 or 24.576 MHz) for all standards • Horizontal and vertical sync detection • Automatic detection of 50 and 60 Hz field frequency, and automatic switching between PAL and NTSC standards • Luminance and chrominance signal processing for PAL B, G, D, H, I and N, combination PAL N, PAL M, NTSC M, NTSC-Japan, NTSC 4.43 and SECAM • Adaptive 2/4-line comb filter for two dimensional chrominance/luminance separation: – Increased luminance and chrominance bandwidth for all PAL and NTSC standards – Reduced cross colour and cross luminance artefacts • PAL delay line for correcting PAL phase errors • Independent Brightness Contrast Saturation (BCS) adjustment for decoder part • User programmable sharpness control • Independent gain and offset adjustment for raw data path. 1.2 Video scaler • Horizontal and vertical downscaling and upscaling to randomly sized windows • Horizontal and vertical scaling range: variable zoom to 1 ⁄64 (icon) (it should be noted that the H and V zoom are restricted by the transfer data rates) • Anti-alias and accumulating filter for horizontal scaling • Vertical scaling with linear phase interpolation and accumulating filter for anti-aliasing (6-bit phase accuracy) • Horizontal phase correct up and downscaling for improved signal quality of scaled data, especially for compression and video phone applications, with 6-bit phase accuracy (1.2 ns step width) • Two independent programming sets for scaler part, to define two ‘ranges’ per field or sequences over frames • Fieldwise switching between decoder part and expansion port (X port) input • Brightness, contrast and saturation controls for scaled outputs. 1.3 Vertical Blanking Interval (VBI) data decoder and slicer • Versatile VBI data decoder, slicer, clock regeneration and byte synchronization e.g. for World Standard Teletext (WST), North American Broadcast Text System (NABTS), close caption, Wide Screen Signalling (WSS), etc. 1.4 Audio clock generation • Generation of a field-locked audio master clock to support a constant number of audio clocks per video field • Generation of an audio serial and left/right (channel) clock signal. |
