10 months ago Added preliminary test item with a high video bitrate, static manifest at the moment. Manifest has just 2160p video resolution, audio is a normal AAC-128Kbit-stereo.
Smaller HbbTV(1080p only panel) devices may not able to downscale this track so only audio track may be played.
Playready2: 2.19 HEVC 2160p high bitrate Playready CENC, h265(2160p hvc1 Main@5.0 32Mbit)
Widevine: WV.7 HEVC 2160p high bitrate Widevine CENC, h265(2160p hvc1 Main@5.0 32Mbit)

10 months ago Dashjs+Windows+EdgeBrowser+HEVC high bitrate multiperiod gives an error, see this ticket. https://github.com/Dash-Industry-Forum/dash.js/issues/4304
4K + HEVC + live + DRM may raise unique issues not raised by our existing streams. We should consider whether it would be helpful to add such a stream to the reference app. It should be noted that live streams are expected to have significantly higher bandwidth than on-demand, potentially 30-35 MBit/sec. A VOD stream to be used with livesim for such a test should be encoded at the higher bitrate.
