Identifying content in a MediaConnect source
The content in an AWS Elemental MediaConnect source is always a transport stream (TS). The TS is made up of one program (SPTS) or multiple programs (MPTS). Each program contains a combination of video, audio, and optional captions.
Obtain identifying information from the content provider.

Information to obtain |
|---|---|---|
| Video | The source content might contain more than one video program. If two video programs are identical, look at the audios and captions in each program. Those might be different, in which case you should choose the video program that contains the audio or captions formats that you want. |
Obtain the PID or bitrate of the video program that you want. |
| Audio | You must work with the audio that is in the same program as the video that you chose. | Obtain the PIDs or three-character language codes of the audio languages that you
want. We recommend that you obtain the PIDs for the audio assets. They are a more reliable way of identifying an audio asset. |
| Captions | Embedded | Obtain the languages in the channel numbers. For example, "channel 1 is French". |
| Object-style captions, for example, DVB-Sub | Obtain the PIDs of the captions languages that you want. |
