3System Level Description

The system block diagram illustrated in Figure 2 provides an example of how the TVP5158EVM may be used for evaluation. Typically, the analog video/audio input is provided by a video source such as a pattern generator or a DVD player running a test DVD. The TVP5158EVM is configured with the 5-V supply and the USB cable provided.

The TVP5158EVM analog video output is standard definition component video (YPbPr). These outputs are then fed into a high-end or studio-quality NTSC/PAL monitor.

The user can also connect the TVP5158EVM to a DaVinci HD EVM and then output combined video from the DaVinci HD EVM to a 1080i HD monitor.
