The Program Service is responsible for:

• Play next program after current program ends.
• Change program when seek outside program boundaries.
• Fetch information of current playing program or asset (VOD)

PROGRAM_CHANGED or ASSET_CHANGED events on the player object are fired when the playback starts or when a program boundary has been crossed.

 myPlayer.on(empPlayer.Events.PROGRAM_CHANGED, function (event, data) {
    data.program // The program object from exposure
 });


 myPlayer.on(empPlayer.Events.ASSET_CHANGED, function (event, data) {
    data.asset // The asset object from exposure
 });

Program and asset (VOD) object can be accessed anytime during playback.

 myPlayer.getProgramDetails() //return current playing program

 myPlayer.getAssetDetails() //return current playing asset

You can go back and forward between programs for a channel.

 myPlayer.playNextProgram()

 myPlayer.playPreviousProgram(end) //If end is true, it play 30 sec from the end

You can always jump to the live edge when playing a channel.

 myPlayer.gotoLive()

The program service can be stopped and restarted.

  myPlayer.stopProgramService()

  myPlayer.startProgramService()

If program service don't receiving EPG when calling next-program endpoint, it start polling for EPG every 2-3 minutes.
Polling for EPG can be turned off with epgPollingDisabled options.
When playing a channel without EPG is't no meaning to poll for EPG.

 options['epgPollingDisabled'] = true; // Default is false
