This is not how it happend with SD-HD transition. Blu-ray players were and still are able to take blu-ray movies and downscale them to 480i, 480p, 720p, 1080i. I have a blu-ray player hooked up to a 720p plasma right now. Before I had the plasma that blu-ray player was hooked up to a 27" SD CRT.
Blu ray players came with component video outputs for years until recently. Many still come with composite video outputs, and analog audio.
Many came with 5.1 or 7.1 analog outputs that were able to decode Dolby TrueHD and DTS HDMA for people that had older AV Receivers that did not have HDMI.
They did this so people can update their players and movies first, and then replace their TVs more slowly over time (since TVs are a much larger expenditure and get replaced less often).
Making Ultra HD Blu Ray movies/players completely incompatible with any older TV is a horrible idea and would probably kill the format, which is going to have a hard enough time surviving as it is since so many people are already transitioning to digital delivery/streaming.
Correct. 1080P doesn't have a content restriction and you can do whatever you want with it. 4K has a content restriction. 1080P was allowed to be down converted. 4K is not allowed the same luxury.
Don't get me wrong though, I have *not* found any link that says 100% that Type 1 will be enforced from day 1. That is just the common assumption.
The only piece of evidence we have right now is that 4K media players require HDCP 2.2. From a link I posted earlier, the Joey 4K has a single HDCP 2.2 output as well.
More evidence from some of the newer AVRs:
4K/60p and 3D video pass-through
- This receiver requires a free upgrade to the HDMI circuit board (see above) to be HDCP 2.2-compliant. Without it, it will not support copy-protected 4K video content.
4K/60Hz Pass-Through: The receiver's HDMI inputs and HDMI outputs support 4K/60Hz Ultra-HD, 4:4:4 Pure Color, and 21:9 video pass-through, a feature of the latest HDMI 2.0 specification for Ultra-HD content. They also support 1080p (24 or 60Hz) for playback of high-definition content from Blu-ray, satellite/cable, and gaming devices.
Note: The AV receiver's HDMI 2.0 jacks do not support the latest HDCP 2.2 copyright protection for 4K ultra-HD content, so it will not support 4K content from satellite/cable providers, online video services, and Blu-ray disc which are copyright protected with HDCP 2.2.
4K Video Upconversion: The Denon AV receiver's sophisticated video processor provides upconversion from standard definition (480i/480p) and high definition (720p/1080i/1080p) sources to 4K Ultra HD (3840x2160 pixels), which lets you connect all your analog (composite/component) or digital (HDMI) video sources to the AVR-X7200W and then connect to your HDTV with just a single HDMI cable.
So I can appreciate and respect the use cases that you and Slice are presenting. I don't want you to think I'm calling them "dumb" or anything . I do however think they are corner cases and that the hardware and content restrictions will not allow for that to happen. Nor do I think the manafacturers have any interest in supporting legacy stuff. They want to sell new models .
If you think about it... there hasn't really been anything cool out in terms of features for like the last 10 yrs. Now 4K is here. Time to move on. 1080P has served us well. RIP buddy .
