Video: This read-only field displays the video stream information
(Video Streaming format and resolution).
• The properties of this incoming (detected) stream is given as: Video Codec
and Resolution .
• An example would be: MPEG2 720x480 . This means that the incoming video
is an MPEG2 video stream with resolution 720x480.
Codec
(Short for
en CO der/
DEC oder or CO mpressor/
DEC ompressor)
• Supported MPEG codecs: MPEG-2 or MPEG-4
• MPEG-2 is typically used to encode audio and video for broadcast quality
signals. The MPEG-2 is enhanced by using MPEG-1's audio (MP2)
component to allow the coding of audio programs with more than two
channels. Video quality is noticeably higher with MPEG-2 vs MPEG-4.
• MPEG-4 is currently used as a standard for the web (streaming media) and
CD distribution, conversational (videophone), and broadcast television. The
biggest difference between these two encoding types is that MPEG-4 uses
about 1/3 to 1/2 less bandwidth for the same quality of video.
Resolution
This relates to the display size/resolution used by the incoming video stream.
• Available resolutions: D1 (default) or SIF :
• D1 is a resolution standard. In the NTSC system, "Full D1" means 720x480
pixels @ 30 fps, and in PAL systems, full D1 is 720x576 @ 24 fps.
• SIF (Source Interchange Format) is a resolution standard defined as 352x240
@ 30fps for NTSC and 352x288 @ 24 fps for PAL.

stream into the following pixel resolutions:
