Accessibility settings might be able to filter out the DVS if embedded into any audio track, because that’s how Samsung TVs watching their PLUS TV service managed it to work around the issue and if embedded into a 2nd audio track you simply flip back and forth between English/Spanish.
Also I watch a video suggested fysabking the DTS and MTS in Dolby Surround Sound neutralized DVS in feeds that listen to it on Dolby 7.1 Surround Sound
so three software options were found DVS:
1) Accessibity text to speech
2) disable DTS, audio 2 and MTS
3) flip language support
So if it’s hard embedded like hard subtitles then these work around options are useless, and obviously it’s only affecting IPTV not subscribed legit devices like Netflix, Samsung TV plus who can stream content that is not infected or embedded this way.
This raises the question:
can the IPTV provider automatically purge such hard embedded DVS LIVE channels from being delivered?
Remove the channels if so infected by DVS?
