Picture Quality rules for TV

Picture quality (including size) was and remains the #1 selling feature for TV. Second and third were always design and sound quality.


This article claims people like navigation options and controllablity; but in the USA settop box world that seems awkward. Maybe people do like more choice than there single STB and TVs can play a prime role in making it accessible.




Video codec with 2x the performance of HEVC?

A private company from the UK called V-nova claims to have developed a new codec called PERSEUS that is at least twice as efficient as HEVC. It is licensing the codec, similarly as with other codecs. The article from Videonet provides more information.

Keep in mind HEVC compression today is not mature yet: there is a lot of improvement possible. So a side by side comparison now is not a “full story”. Nevertheless: if the codec performs significantly better today than HEVC will do in the foreseable future it may make serious impact in the industry. A factor 2 bandwidth gain is worth billions in the fast growing OTT industry for example.

An intrinsic property of the codec is that it seems to be “hierarchical”; a property often aspired to but never deployed. Practical value is low – the bold statement and comparisons presented from the hierarchical advantage perspective by V-Nova degrade confidence.

Update: April 10, 2015

V-net has gathered opinions from the industry. Key issues for PERSEUS to overcome:

  1. Proving the claim of 2x+ compression gain holds up under a broad set of content inputs and compression rates
  2. Gaining traction with consumer decoder silicon manufacturers in firmware/hardware.
  3. Ensure the third party patent situation is clarified: the compression field is littered with patents; lawsuits may come to V-Nova and their customers if PERSEUS implementations violate those patents.

In view of the problems of (2) and (3) broad consumer product implementation will take quite a while even if the compression rates prove to be robust.

UHD and watermarking

According to movielabs watermarking sould be used on UHD content, though it is not too specific on how it should be deployed. Herewith a public announcement of such a new deployment. Watermarking needs a (big) push from the content industry: the incentive for distributers and aggregators to deploy watermarking to trace leaks is too weak.

VOD and UHDTV: ideal package

A practically ideal marriage: Netflix and SuperHD. Content is hard to come by so a on-demand VOD or subscription VOD service like Netflix are the ideal ways of bringing the scarce, often quite premium content to the customer. If the internet connection can sustain the streaming of course: some offline HEVC compression may be helpful there.
