Configuring Live Profiles
A Live Profile is a set of audio and video settings configured to fit within specific broadcasting requirements. Live Profiles can be configured from either the Web Interface or on the Unit Front Panel.
The unit is delivered with three (3) default Live Profiles:
- DEFAULT
- LOW DELAY
- HQUALITY 10s
Recommendations when configuring a Live Profile:
End-to-End Latency | Broadcast over SST | For CBR, enter a value within 500ms - 10s range. | |
|---|---|---|---|
| Broadcast over SRT | |||
| Video Return | |||
| Broadcast (low latency mode) | For CBR, enter a value within 80ms - 10s range. | ||
| Bitrate Control Mode | CBR mode for streaming over managed networks. | ||
| Resolution | As source for encoding in the same resolution as source. | ||
| Live Bitrate (static resolution as source) | Video Resolution | Bitrate Range | |

The following Transport Stream settings are available if the Application type is set to Broadcast SRT:
| Bitrate Control | VBR CBR |
|---|---|
| TS ID | 1 - 1023 |
| Program Number | 1 - 1023 |
| PMT PID | 32 - 8183 |
| PCR PID | 32 - 8183 |
| Video PID | 32 - 8183 |
