Due to breaks in transmission on Arq A at 0145hrs, I looked at the transport stream and could see a 10th stream being tested and null packets down from 9Mbps to 6Mbps. It stopped at 0200. Although now back to nine streams, the null packet rate has remained at about 6Mbps.

The Freeview EPG confirms an extension in price-drop TV hours from midnight to 2am from 29/6/12. This may be post DSO only as pre DSO Mux C is full.

None of the non BBC muxes literally timeshare streams any more. All non BBC services have a unique video PID. As long as the total number of video streams on Arq A or SDN does not exceed twelve at any one time there will be no problem. For ease of understanding though it is easier to represent the twelve streams as if channels were virtually timesharing especially if full capacity is reached.

So if this change is confirmed and price-drop tv continues past midnight to 2am, then there will be ten streams on Arq A between midnight and 2am; and at other times nine. This will be in post DSO areas only as pre-DSO Mux C is limited to nine streams in 16QAM.

Representing it graphically would place price-drop tv on a new 10th stream leaving its former virtual timeshares on their own stream.

Which reminds me, I haven't updated my multiplex graphs in a LONG time. I should do, I have all summer now.

Well I don't think 00:00-02:00 is a prime viewing time so that's OK. But for normal hours I really hope they don't try to squeeze in any more channels. 9 channels sharing 27 Mbps should be the maximum limit.

They have 9 channels carried in 18Mbps pre-DSO, so they wouldn't see a problem fitting 13 channels into 27Mbps.

Since when? The diagrams on the website I listed above shows 8 channels on the 24 Mbps muxes (teletext doesn't take up as much as an actual channel) and 6 on the 18 Mbps muxes*, both of which fit with the 3 Mbps per channel minimum.

*One 18 Mbps mux, Mux C, has 7 channels. This is naughty.

uk free is not known for its accuracy. Mux C has nine streams not seven. There is no 3Mbps minimum. Some video streams run at less than 1.5Mbps average.

Want accuracy?

Add www.ukfree.tv to your /etc/hosts file pointing to 127.0.0.1 so you don't accidentally visit it and assume it has even vaguely accurate information. If you're not a computer guy, this process makes it impossible to visit the site via its DNS address

Hmm. I know there is no "3 Mbps minimum", that was my own standard. No wonder Freeview looks like arse, glad I have satellite.

price-drop tv continued on past midnight and will be on until 2am and until then there are ten streams on Arq A. The channel stated on air that its live show would be on Freeview until 1.30am with no mention of exceptions in Tyne Tees & NI. 1.30am-2am is a recorded "highlights" segment.

Do you happen to no what time price-drop came on air this morning?

If price-drop can use the whole stream there will be spaces for a new channel that price-drop vacate.

If, like me, you are still running on Windows XP and not a Unix-type computer the file is at C:\WINDOWS\system32\drivers\etc\hosts (no suffix!). Other Windows versions may store this elsewhere.

On the other hand, visit the site and be sceptical.

It's still /etc/hosts, just relative to the drivers directory


Yeah, it was a joke - the site does occasionally have useful reference on it (eg the UHF channel numbers for a given transmitter, it's usually the most convenient to view compared to the official data), but even that reference stuff I don't really trust.

I don't think anyone trusts it do they? Its posted continual factually incorrect claims in the past, stood by them, then looked redfaced when they suddenly disappear because the owner finally realises what we already knew!

I guess the vacant streams won't be filled by ESPN in 24 hours a day transmission will they..

Ukfree.tv is mainly an easy reference for transmitter information and maps, there are a few errors, and sometimes speculation is presented more like fact, but it's still worth looking at.

Also I notice that whenever you search for a transmitter using Google, the ukfree.tv entry is almost always top, so their SEO is obviously very good. Like others I do find it useful for basic transmitter information, just cross-check everything.

Have any of these expressed the remotest interest in being on Freeview? I doubt it.
