3.8.3
Line-Interleaved Mode Support (TVP5158 only)
The TVP5158 supports 2-Ch, 4-Ch, and 8-Ch line-interleaved modes. In the line-interleaved mode, the
video channels are multiplexed together on a line-by-line basis. Compared to the pixel-interleaved mode,
the line-interleaved mode significantly reduces the code complexity and MIPS consumption of the backend
processor. The 8-Ch modes require connecting two TVP5158 devices together using a video cascade
interface (see Section 3.8.3.3). The TVP5158 also supports different image resolutions (for example, D1,
Half-D1, and CIF) in the line-interleaved mode. All supported line-interleaved modes are shown in
Table 3-10. Output Ports Configuration for Line-Interleaved Mode

3.8.3.1
2-Ch Line-Interleaved Mode
TVP5158 supports 2-Ch line-interleaved mode at 54 MHz. The video output data with D1 resolution from
any two video channels is multiplexed together on a line basis. The output ports DVO_A and DVO_B are
used in this mode. The output clock OCLK_P is synchronized with both output ports.
3.8.3.2
4-Ch Line-Interleaved Mode
In 4-Ch line-interleaved mode, the video output data from all 4 channels is multiplexed together on a line
basis. The output resolution of video data can be D1, Half-D1 or CIF. For D1 and Half-D1 output
resolutions, the video output port can be configured to support 8-bit BT.656 or 16-Bit YCbCr 4:2:2 data
with embedded sync. Port DVO_A is used for 8-bit output. Ports DVO_A and DVO_B are used for 16-Bit
output. The output clock OCLK_P is synchronized with all four output ports.
TVP5158 supports multiplexing 4-Ch CIF and 1-Ch D1 data together and then output through DVO_A at
54 MHz. 1-Ch D1 can be from any one of 4 video channels. In typical surveillance applications, CIF
resolution is used for recording and D1 resolution is used for video preview.
