8.5 Example TVP5158 Property Pages

Example property pages are shown in Figure 21 through Figure 24.

Some of the controls for the Output Formatter (OFM) page only exist for video decoder 1. Figure 21

shows the OFM page when Decoder 1 is the selected decoder. Figure 22 shows the OFM page when

Decoder 4 is the selected decoder (some of the OFM controls are not visible). They would also not be

visible for Decoder 2 and Decoder 3. To change the Port A selection, for example, Decoder 1 must be the

selected decoder.

The Audio property page only exists for video decoder 1. To access the Audio controls Decoder 1 must be

the selected decoder.
