SatcoDX Satellite ChartColumn Explanation |
| V-Pid | Video Program Identification |
|
The Video PID defines the data substream containing the video signal. Radio signals, which by definition don't contain any video signal, carry the value 8191 (this means empty) in the Video PID. The SatcoDX charts do not carry this 8191 value to make the charts clearer, and because receivers will anyhow shut down the video when there is none. |
