Endpoint Channel Retune

The Need for Channel Retune

TV channel signal quality can fluctuate due to variations in end-to-end delivery. During temporary degradations—such as packet loss—IPTV endpoints tuned to the affected channel may freeze or fail to display images correctly, even after the signal quality has recovered.

To address this, the “Endpoint Channel Retune” feature becomes essential. It ensures that endpoints can reliably resume proper channel display once signal quality is restored, making it a desirable—or in some cases, mandatory—capability for robust IPTV performance.

Examples include Amino H.200, Amigo, Google Chromecast, Onn Streaming Box, etc.

The process relies on monitoring the positionChanged event emitted by VLC Player during channel playback. This event typically occurs every 200 to 300 milliseconds.

A channel retune should be triggered if no positionChanged event is received within a predefined Retune Interval.

The Retune Interval should be adjusted based on the channel type: 2 seconds for IGMP channels and 10 seconds for HLS channels.

The retune process also applies to scenarios where Android endpoints stops playing a file-based IGMP channel upon reaching the end of the file.
