Any reason to keep standard def channels if you have HD version?

alright, can we talk about the elephant in the room, linux and cccam etc. or is that for another website?

Since you're talking about piracy (i.e. theft) that's not for any thread on here.

Yes, how long can it take for the regional news to buy a few Hi Def cameras and update. Its been at least 7 years now having to switch from BBC on 101 to channal 1 at 6.30 pm to receive local news in dull old non HD.

The issue isn't a few HD cameras but everything from the cameras to the mixers, to the links from the studio to the transmitters and the transmitters themselves needs to be updated or altered, which costs a huge amount and in some case simply isn't possible

From my understanding the BBC has been updating the regional/local studios but that still leaves the actual broadcast, and that leads to a bigger problem.

There isn't (from memory) space on the transmitters to do HD for BBC regional/local channels. and the cost/space needed to do it over satellite and cable is extremely high as it would require something like another 14 HD channels that could be picked up by existing sets (when the next generation of receivers comes in and we switch over to better encoding that might change).

IIRC we're still using MPEG2 for HD (certainly terrestrial DTV HD), which means that each HD channel takes up about the same amount of bandwidth as 4 SD channels, and there is a finite amount of bandwidth that can be used for each transmitter site without either clashing with other transmitters or being uneconomical to run as you need another transmitter (which is the reason some areas don't get the same number of channels as others, and some only get the "PSB" transmitter of BBC/ITV/C4/C5).

This is the explanation from the BBC

The transmitters are all capable now of transmitting local news in HD, it's the distribution network as well as the studios that need upgrading.

Only in the sense that there is a signal spread across a number of discrete frequencies from the satellite carrying a few hundred channels

The SD channels are split across 10733, 10788, 10803 & 10818 while the HD channels are on 10847 & 11023

I think you're talking specifically about the transmitting satellite - my comment was general, across Freeview, cable and satellite - in that whether HD or SD, it's all just ones and zeros. The original questioner thought they needed a stronger signal for HD - whilst it needs more bandwidth, that's not really true.
