Video Options
Video Codec: This selects the video compression standard used for this channel.
MPEG2 is the default. H.264 is optional on some models. Certain product models have
only MPEG2, or H.264 or both.
Resolution: This is the output resolution for the channel in horizontal x vertical pixel
units.
Standard Definition default setting is 720x480.
High Definition can be 1920x1080 or 1280x720. The default is 1920x1080, but you
may need to change this depending on your source.
Other resolutions are available which are smaller than HD or SD inputs. If you select
one of these smaller resolutions, the video signal will be down scaled.
Frame Rate: This is the output frame rate for the channel in frames per second (fps)
units.
Full: this will maintain the same frame rate as the input signal.
½ or ¼ : these will reduce the frame rate by these associated amounts.
o
For SD NTSC sources, the ½ setting will result in 15 fps, and the ¼ setting
will result in 7.5 fps.
o
For HD 1920x1080i, the ½ setting will result in 15 fps, and the ¼ setting will
result in 7.5 fps
o
For HD 1280x720p, the ½ setting will result in 30 fps, and the ¼ setting will
result in 15 fps.
o
Output Format: This is the output frame structure for the channel.
De-Interlaced: this setting will de-interlace the input signal to create a progressive
output signal. The de-interlacer is a high quality multi-frame motion compensated
de-interlacer.
Same As Input : Select Same As Input to keep the frame structure the same as the
incoming signal

Audio Options
Audio Codec: Several audio compression standards are available on different product
models. The default audio codec is AC3. Codecs available on certain models include
AAC-LC, AAC-HE, MPEG1-layer1/2, MPEG2-layer1/2, and MP3.
Bitrate: Several audio bitrate value options for the AC3 encoder are provided in Kbps
Stereo signals are typically encoded at 128,192, or 256 Kbps
If you have a model with HD signals, 5.1 audio is supported. Typical bit rates used for
5.1 are 384, 512, or 640 Kbps
