If someone enters this thread they could reasonably believe no, or limited, channels are likely to launch based on your false claims. It is entirely responsible that someone corrects you.
You admit you don’t know why ITV HD is in MPEG 2 or why those frequencies have less channels than others, yet we have to take the rest of your claims as gospel that for reasons unknown they are unavailable for use.

- TSID 101 has a number of different frequencies in each region. I did say that I was hoping that SP would see the post as he might be able to explain better than I can.
- If you dispute the fact that it is currently the policy of VM to only have a max of six HD channels per mux, take a look at the TSIDS on digitalbitrate. Each TSID has six HD channels on them apart from one which has five. I'm assuming that this will be used to add GOLD HD. When it is, if the system isn't recalibrated, there will be no more room for any more HD channels.
Nobody has suggested that VM can't or won't recalibrate their system in order to be able to add more HD channels, in fact, it's almost inevitable that they will do. What they will do though is not known at this point in time. Because the information from the scanners will no longer be being posted, this forum probably won't get to know either.
I note that you once told me that you were able to scan the system, are you still able to do so?
- As to whether unused frequencies could indeed be activated or re-activated, who knows, but at this point in time this has not happened. The trend has actually been to take away frequencies from DVB-C and reallocate them for broadband. It's believed that this is in response to Ofcom complaining that some users were getting poor broadband speeds at peak times.
If there were unused frequencies available, i'm sure that they would have used them instead of taking capacity from the cable TV service, which itself is fast running out of capacity under the current configuration. What makes me think that VM have something in the pipeline with regards to TV capacity is that they have reallocated resources to broadband, whilst knowing that cable TV capacity is also under pressure. Presumably they have a future plan in place that will see the current service need less resources to the extent that there will again be spare capacity to add further channels, despite broadband taking away some of its space.
- I have made it clear (as have you) that there are various things that VM can do to get more out of their existing TV capacity. I have never, ever said that there will not be any further channels added, merely that,
at this point in time capacity is almost full
under the current configuration . This is something that you don't seem to be able to accept or understand. If the capacity is nearly full, it's nearly full. What VM will do to deal with this problem is another matter entirely.
- I said that I have no idea why some of the ITV regions are still in MPEG2, because I don't, but it is a fact that they are and changing them over to MPEG4 would help the situation. Only VM know why they weren't (or if there is some technical reason that they can't be made so yet), but,
at this moment in time this is the situation. This is why I said that I hoped that SP would see the post.
- Verifiable proof has been provided with regards to the capacity issue, so it's not a case of people being expected to believe this based on trust. Me not knowing the reason why all the ITV regions were not changed over to MPEG4 is irrelevant to this.

If we take your stance to the extreme Virgin would never add channels except on a one in one out basis ... the “current configuration” would never allow it. That’s why the current setup is useless in projecting the future. That applies today just as at any point in the history of cable tv.
Sky would still have 4 channels on the Astra 1 satellite if the “current configuration” was set in stone.

But at no point have I suggested that the current set up does project the future....
All I have done is provide information with regards to the configuration set up at this point in time and that is that the system is nearing full capacity.
What VM can or will do to deal with this issue is another matter entirely.

And a minor benefit of 64-QAM for software delivery is it is a bit more tolerant of network noise, so we may as well stick with it until the bandwidth is needed for something else.
All transport streams are carried on a national network. The regional headends select the ones they need, and ignore the others. So they pick up all the national ones, plus whichever regional ones they need to serve their local users.

It's because they are acquired through some non-standard equipment, which is a consequence of the way ITV's distribution network works. It'll get sorted one day.

Many thanks for explaining SP, I had wondered why these apparent anomalies existed.
