Is TV Channel API Deprecated?

I’m working on a Hospitality TV interface and would like to be able to show the TV channels within the app.

I can open a TV Window using the TVWindow API ( TIZENH GUIDE ) but I can’t find any info on how to change the channel.

This page shows a TV Channel API in the TV Controls section:

but it just goes to a 404 page.

Is the TV Channel API deprecated now? How should I be accessing the channels?

I’ve also tried to open a UDP channel with AVPlay, but it just hangs when it gets to the play command. I can play a hosted MP4 video with the same method, and the UDP channel shows correctly when I include it in the TV’s channel map, so I’m not sure what I’m doing wrong there.

Thanks in advance!

I’ve seen an older app use the b2bbroadcast API, but I can’t see anything in the documentation about IPTV/UDP channels: TIZENH GUIDE
