MPTS for choosing the right program

MPTS (MPEG transport stream) is used in broadcast systems and is designed to be used in terrestrial or satellite broadcasts, for example. It can carry multiple programs and each program contains a pack of video streams, audio streams and metadata (if present).

Comprimato Twenty-One Encoder has the support for receiving and processing the MPTS streams and detects all programs and allows its users to choose them easily.

Figure 30: CONFIGURING MPTS

When you wish to choose which program to use, you need to allow the Program number configuration in the Input stream configuration options. Once allowed, the user can select the program number from a dropdown menu. The current program informs about the current configuration, while the Configured program has to be applied first to take effect. If you will not set up anything, the first program in the list is selected. If a Configured program number is not present in the stream, Twenty-one encoder reports an error. Once you change the program number and apply the configuration, a video with another PID is detected (if present).
