The quality of the video output from the S-Video video output interface is better than that output
from the CVBS video output interface. Therefore, it is recommended that you use the S-Video

To ensure the quality of the video output from the terminal, the resolutions of the videos input
to and output from the terminal need to match each other. For example, if a video with a resolution
of 1080p and a frame rate of 30 is input to the terminal, set the resolution of the output video to
1080p and the frame rate to 30 Hz or 60 Hz. If a video with a resolution of 1080p and a frame

This specifies whether to adjust the aspect ratio of a video to fit the video
into the screen.
l Stretch: The aspect ratio can be changed.

For example, to change a wide-screen video to a narrow-screen video,
the system cuts the left and right sections of the wide-screen video, and
then stretches the video to the full-screen mode.
