MOD-HDMI-Q : Operation Manual 1v0
2. Encoder Settings
In this category the user is able to adjust parameters of the H.264 encoder, as
described below:
2.1 Input source
– Select the primary input source
2.2 Video BR (Mpbs)
– Set the video bitrate
2.3 Audio BR (Kbps)
– Set the audio bitrate
2.4 Audio Encoding
– Select the audio encoding
2.5 HDCP ON/OFF
– Enables/disables HDCP
2.6 Output Video Res
– Select ouput video resolution
3. Multiplexer Settings
In this category the user is able to adjust parameters of the MOD-HDMI-Q
multiplexer, as described below:
3.1 Network Name + ID
– Enter the Network name + ID*
3.2 Program Name + ID
– Enter the Program name + ID
3.3 Provider Name
- Enter the Provider name
3.4 Original Net ID
- Set the Net ID (0-65535)*
3.5 TS ID
- Set the Transport Stream ID (0-65535)*
3.6 PMT PID
– Set the PID value
3.7 Video PID
– Set the Video PID value
3.8 Audio PID
– Set the Audio PID value
3.9 LCN No
– Set the LCN No (1-999) (must be enabled first)
3.10 LCN Provider
- Set the LCN provider
* TS ID must always be different between DVB-T modulators in the same network.
Caution!!!
• Modulation settings must be applied with care and in order to have adequate
output bitrate. The output bitrate (which can be calculated from the tables in
Appendix B) must be equal or greater than the total sum of the bitrate of the
encoders.
Example:
Assuming we select the following modulation settings:
Modulation:
8K
Constellation:
16-QAM
Code Rate:
5/6
Guard Interval:
1/32
Bandwidth:
8MHz
•
We have an output bitrate of
20.107 Mbps
according to Appendix B.
• This means that encoder’s bitrate must be adjusted in such a way that the
total bitrate of the encoder does not exceed the 20.107MBps limit, otherwise
artifacts may occur.
• For example, one valid selection in case of four encoders would be to set each
encoder bitrate to 5Mbps since: 4 x 5Μbps = 20Mbps < 20.107MBps
