Combines the individual programme streams from the encoders into one transport stream, which is what the modulator and the distribution side actually consume.
Getting this stage right is what stops the commonest complaint in a new installation — channels that exist but cannot be found on the receiver.
Key features
- Multiple transport stream inputs
- PID remapping, automatic or manual
- Accurate PCR adjusting
- Automatic PSI / SI table generation
- Single combined transport stream output
- Web-based configuration
- Rack mounted, front access
- Presets for common channel line-ups
