Changing the Video Input/Output Methods

A.1 Changing the Video Input/Output Methods

The EVM can input video using the following methods:

❏Composite [default]

❏S-Video (best quality)

In addition, there are three types of video output:

❏Composite [default] (lowest quality)

❏S-Video (medium quality)

❏Component (best quality)

There is a significant quality difference between the different inputs and outputs. However, the cables in the DVEVM kit support only composite video. You will need to get S-Video or Component video cables from another source.

A.1.1 Using S-Video Input

To switch to higher-quality S-Video input, follow these steps:

1)Connect your S-Video connector to the S-Video input port, which is directly to the left of the currently-used composite video input port.

2)Select S-Video input on the command line when you execute the encode or encodedecode demo using the '-x' flag.
