TV Resolution – SD, HD, 3D and now 4K

As with still cameras which have steadily increased in resolution, with have seen TV’s continually step up in recent years.

From CRT TV to Flat screen, then HD; in our consumer society there is always a need to make people upgrade. 3D was the next big thing, but while moderately successful in movie theatres was less so in homes. Now we have the next big thing 4K which has 4 times the resolution of HD.

I suspect we will see still cameras with 4K soon, we have already seen some mobile phones with 4K but I expect thats more marketing over usability.

One interesting aspect of this is going to be what happens with media and to broadcast. While Blue Ray can cope its likely we will need an updated format as we are close to its limits and that leaves no room for extras. Broadcast is even more of an issue, we would loose the majority of our channels as there is insufficient bandwidth to deliver 4K channels in the current numbers.

Interestingly Sony have come up with an interesting answer. Last year there first 4K TV coast $25,000, this year the current model is $5000. For deliver of content they have released a 4K media server at $700. Movies can come on either SD card or by download.

For many physical media is a thing of the past and it seems 4K may mean that for movies as well.
