Parameters
Description
Channel
 The channel quantity represents the supported max.
transcoding channels.
 For 2-channel transcoding module, channel1~channel2 are
available in this option, while channel1~channel4 are
available for 4-channel module.
 Each channel transcoding parameters can be set in
separated pages when selecting different channel.
Video Encoder Mode
Set the encode mode, options are available for: CBR/VBR.
CBR: the encoded program bitrate is a constant value.
VBR: the encoded program bitrate can be variable according to
the input program content
Video Encode Rate
Set the encoded video bitrate, range from 1.0 to 20.0Mpbs
Audio Encode Rate
Set the encoded audio bitrate, range from 64 to 384Kpbs
Total Encode Rate
Total bitrate automatically by the software which is not editable.
The bitrate is summed up by audio and video bitrate.
Volume (0~49)
Define the output channel volume after transcoding.
Level 0 means mute while level 49 is the Max. volume output.
Video VBR Max.
Encode Rate
This parameter takes effect only when the Video Encode Mode
is set to “VBR” on TC4 module.
Max. Encode Rate: base on the parameter set in “Video Encode
Rate”, it should be input a parameter from 1.75 to 2 times the
encode rate.
Video VBR Min.
Encode Rate
This parameter takes effect only when the Video Encode Mode
is set to “VBR” on TC4 module.
Min. Encode Rate: base on the parameter set in “Video Encode
Rate”, it should be input a parameter from 0 to 0.75 times the
encode rate.
GOP Struct
Set the GOP structure, options:
IBBPBBPBB/IPPPPPPPP/IIIIIIIIII/IBBPBBPBB
Latency Adjustment
To adjust the latency between input and output.
Aspect Ration
Conversion
Options are available for 4:3 and 16:9 aspect ratios.
Output Video
Resolution
Set the output Video resolution
After setting all the parameters, you should press ‘Set’ button to save the settings.
