I'm pleased to announce a new service for UK Free TV: the Knowledge Base

This service has replaced the all "Diagnostics" section.   There was a problem with the logic with the old service that didn't allow new help to be added to the original data.

The new service can very easily be extended to include new issues and problems as they arise.  The current design maps the most popular questions to have easily reached answers.  It also takes you directly to the page with the answer on it, cutting the number of clicks required. 

I have left the old Diagnostics pages up - with the content grayed out and crossed out - as there are many useful comments on those pages.   I will, eventually, migrate these to the new system.

As ever, please let me know what you think can be added.

To do that would require every frame to be uniquely identifiable so that matching HD frames can be paired with their 4k counterparts. As the system currently used does not have that unique identifaction ability there is no way to combine them without serious visual artifacts that would be even more disturbing that the pixilation we already see.

The ability to store numerous frames is not so much of a problem these days, memory is relatively cheap for large amounts (that is for RAM memory and not hard disk type) and the electronics needed to control it all should not be an insurmountable problem, it's the lack of ID per frame that is the 'stumbling block' currently.

Some years ago, the firm I worked for wanted to make a 'video wall' before they became commercially available. The main problems we found were that digitisation was far too slow in those days (1980s) and data storage was not only slow by extremely expensive! We even discussed the ideas with both BBC and Central TV (I worked in the East Midlands) and they were interested in the ideas as they were trying to develop the same for theiur studios - but they were finding the same problems. Modern electronics has overcome the speed and cost so we now have video walls all around. But they have not solved the interleaving problem yet either.

Charles Stuart: Your idea is an interesting one, but its perhaps a difficult solution to a problem that doesn't really exist. 4K via broadband is quite possible - Netflix is already supplying House of Cards in 4K, and it needs about 15Mbps Netflix 4K streaming requires double the bandwidth of U.S. average | BGR - which is certainly fine for my connection, and many other people with fibre. However, if your not on fibre, or we all want to stream at the same time, then yes, that is a problem.

Likewise, using a dish or even an aerial to deliver 4K is also perfectly possible, and the standards have finally been agreed for Europe 4K TV channels on the way as DVB-UHDTV standard is approved | News | TechRadar . The big problem is getting all the kit in place, but its not hugely difficult.

Combining the two together sounds like a nightmare, so I suspect we will get fibre feeds first, with perhaps transmission at a later date.

Tony: Two cables in each room points to the previous occupier using either Sky+ boxes or alternatively Freesat PVR's (twin channel recorders) in each of the rooms in question

Try connecting your old Sky box into both cables in "each" room, as these cables are completely independent of each other even although they all go into (or should do) the LNB on the dish, which by the fact of having six cables connected into it must be of the type known as an "OCTO" (8 output) block, although obviously only six of the eight ports are being used.

If the result of the test is "no signal" on all six cables, then one of the following reasons has to apply.

(1) The dish having moved slightly out of alignment, e.g: through being blown by high winds or accidentally knocked against.

(2) The cables in question having been damaged.

(3) The LNB has failed, albeit this being unusual, a more likely bet being that your old Sky box is defective.

Freesat boxes can also be used to test dish leads, as Freesat boxes are 100% compatible with Sky dish installations. As far as Sky boxes are concerned, all Sky boxes nomatter whether Sky+ or not (such as yours) can receive non subscription channels without any card being used, although Sky+ devices are only able to record / playback previously recorded programmes when a subscription is in force.

Further advice dependant on feedback.
