The TVP5160 input-to-output processing delay depends on the operating mode and the video standard.
When 3DYC is enabled, the processing delay is approximately 1 frame and 2-1/3 lines. When 3DYC is
disabled, the processing delay is approximately 2-1/3 lines.
2.6 Fast Switches for SCART and Digital Overlay
The TVP5160 decoder supports the SCART interface used mainly in European audio/video end
equipment to carry mono/stereo audio, composite video, S-Video, and RGB video on the same cable. In
the event that composite video and RGB video are present simultaneously on the video pins assigned to a
SCART interface, the TVP5160 decoder assumes they are pixel synchronous to each other. The timing for
both composite video and RGB video is obtained from the composite source and its derived clock is used
to sample RGB video as well. The fast-switch input pin allows switching between these two input video
sources on a pixel-by-pixel basis. This feature can be used to, for example, overlay RGB graphics for
on-screen display onto decoded CVBS video. The SCART overlay control signals (FSS) are oversampled
at 4× the pixel clock frequency. The phase of this signal is used to mix between the CVBS input and the
analog RGB inputs. This improves the analog overlay picture quality when the external FSS and analog
video signals are generated by an asynchronous source. The TVP5160 decoder has two programmable
delays for component video to compensate for composite comb filter delays and two programmable delays
for digital RGB to compensate AFE and decimation filter delays.
If the overlay output is digital supporting 8 colors of data, the TVP5160 decoder can take digital overlay
inputs using terminals C6, C7, and C8. For this mode, output must be the 10-bit ITU-R BT.656 mode.
Figure 2-6 shows the block diagram of two fast-switches. Table 2-4 shows the fast-switch 1 and 2
controls.
