3 System Level Description

The system block diagram illustrated in Figure 2 provides an example of how the TVP5160EVM may be used for evaluation. Typically, the analog input is a CVBS signal provided by a video source such as a pattern generator or a DVD player running a test DVD.

The TVP5160EVM itself is configured with the provided 5-V supply and the parallel port cable. The analog output is typically YPbPr to reduce the number of artifacts caused by backend processing or re-encoding. These outputs are then fed into a high-end or studio-quality display monitor such as a Sony Trinitron.

At the same time, the CVBS output from the encoder may also be fed into a video test measurement system such as the Tektronix VM700. This allows various tests to be run and also allows the user to analyze the video waveform or vectorscope.
