Everything depends on HTML5 <video> MSE EME and C-ENC format for encryption. ooVoo comes after it's in the browser, the rest follow in no order that I can determine over a very short time period compared to how long we have been waiting (since 2010).
1) Plans are for VR devices to display 3D TV.
2) UHD Blu-ray and digital bridge proposed by Sony-Panasonic-Fox uses the same standards as UHD TV and gets the industry ready for 4K TV.
2a) Skipping over DLNA 2 which should have launched in 2014 and is now outdated, Vidipath DLNA 3 uses the same standards the digital bridge and UHD IPTV uses
2b) DLNA 4 launches sometime in 2016 and is required for 1080P and IPV6 ** Sony may be waiting for this **
3) UHD TV is launching 2016 (tuners needed for older 4K TVs Network tuners?)
4) Korea plans to have UHD broadcasting Feb 2017 and to broadcast the Olympics Feb 2018
5) Likely the FCC will accelerate the adoption of UHD TV (ATSC 3)
6) Cell phones are likely going to be mandated to support ATSC 3 for Emergency alerts.
7) We are likely to get Antenna TV gateway/DVR boxes to support ATSC 3 in the home. (
Like NASNE)
8) 2018 Cable TV can have DSS so no cable box needed and the mandated FCC/DSTAC STB for Cable TV is a reality.
The world wide 4K TV that the US calls ATSC 3 has the main screen as a
web page using the C-ENC format for HTML5 <video>MSE EME delivery (page 6 and 18). ATSC 2 is just using a web page for XTV which requires an overlay. Both ATSC 2 and 3 have DRM beyond the copy-no copy flag which is a first for broadcast TV.
Commercial launch for ATSC 3 2016 page 34.
Korea wants to broadcast the Olympics in 4K Feb 2018.
The FCC has sold so much TV bandwidth that it's going to be difficult to have both the old standard and new standard supporting the same channels at the same time. As a result of this and Cell phones being able to reliably and robustly receive TV in a moving car, a PUSH for ATSC 3 and a quicker than normal phasing out of the older incompatible standards will happen (this in multiple papers). This may be alleviated with STBs like the PS4 and XB1 connected to Network tuners able to downscale 4K and receive multiple 1080P channels in a HEVC container. This downscaling and HEVC multi-view codec which is also required for 3D is part of the UHD Digital bridge and mentioned in Playready ND papers. The UHD TV signal is already IPTV with the C-ENC format which is used by Playready and HTML5 <video> MSE EME.
3D is coming to 4k TV (Virtual Reality devices), Phones, Pads, cars...it's already in the planning stages as seen in the underlying transport mechanism and W3C extensions.
