  • The overnight scan showed changes to NIT linkage. These changes will, most likely, have occurred during Friday but there wasn't a Friday evening scan this week. I'll post a summary table later this weekend.

  • There's gaps in the Factual channel numbering at 248-249, 253-255 and 262-264. Assuming the new Sky channels take up 4 (2 HD, 2 SD) and the existing channels don't want jumped over, I can see a reorganising of this and a knock-on reorganisation of Lifestyle after. Though the slates for Lifestyle appearing first seems odd if it was that.


    Another possibility is Lifestyle may be merged into General Entertainment numbering or moved closer. 231-244 is empty.

    I think they'll go after 230 too.

    I will post the NIT linkage summary at some point. I've been getting bogged down in the radio project for a while, figuring out reference codes to link all of the tables together. Station names have changed frequently over the years, as has ownership details and service areas, so a massive task. Also, a lot of the earlier stuff has never been digitised. I can't even cheat and use IBA records as they haven't been digitised either. Fun times...

  • One of the analysts asked why the new level 3 configuration for Uddingston didn't show up in the same way as the updates for other regions. The answer, it probably did but the system hasn't picked it up. So a note about the updates.


    At the moment, only 28 of the 68 regions monitored have level 1 updates. All 68 networks have a level 1 configuration but, clearly, not all of them update. So, it's possible that the configurations of those not updating redirect to the configuration of another region. Or, they may simply not require regular updates.


    As of the last update, only TTA Knowsley DMC (Hayes_RHE) and 9 other networks have regular level 3 updates. For level 3, only 32 of the 68 networks have a level 3 configuration, so something that isn't required in all areas (unless another level of the configuration redirects elsewhere).


    For Uddingston, the new config version is 12. In line with other updated regions, it will have been rolled over to the latest "version 11" before updating to version 12. However, Uddingston had been running a legacy config version 11 and the system cannot pick up a change from a legacy config to newer config with the same version number. This isn't a problem with the analysis routines, it is simply because config version numbers are reused. The version numbers cycle through a range of numbers, when the end of the range is hit, it loops back to the beginning, so this type of thing will happen occasionally.


    There are still no plans to look beyond the configuration and into the actual data streams, so the full nature of these changes will continue to be a mystery.


  • The overnight scan shows that channel code override flags for the above have now been removed. There will be no obvious change for customers.

    This post was deleted by the author themselves ().
  • Some convoluted changes overnight so the scanner's analysis has gone off to the analysts for them to work their magic.


    In the meantime, lifestyle channels have moved and this has appeared in the old slots:


  • The mysterious Channel A HD and Channel B HD have been given legacy XL/Full House pack flags and flags for the new Full House Extra tiers - consistent with channels operated by Sky.

  • Food Network moves from 278 to 285

    HGTV moves from 279 to 286

    Home & Health moves from 280 to 287

    Discovery Shed moves from 281 to 288

    Travel Channel moves from 282 to 289

    HGTV+1 moves from 283 to 290

    Home & Health+1 moves from 284 to 291

    GOD moves from 287 to 292

    Horse & Country moves from 298 to 293

  • ...and, if the many service related changes weren't enough to cope with, VM has also updated qutie a lot of frequencies on the Brighton and Hersham networks...

  • Thanks for the info JJ.


    Looks like those mysterious A & B channels indicate we maybe getting the Sky factual channels next week when they launch.

    VM seem to have been a little overkeen to copy the config over from the "Channel update" slates.
  • At this point I noticed that VM had tried to allocate 12 pack codes to SID 1402 "Lifestyle Slate" on the early overnight scan and I couldn't paste the analysis data into the summary as there was a buffer overflow - the analysis was set up for a maximum of 10. The database had trapped and commented the error but the analysts hadn't picked it up. Understandable as they aren't actually trying to use the data. A later scan showed that VM reduced the number of pack codes, so 12 perhaps also caused errors for VM. The rest of the data will be posted later, after the coders have increased the number of fields available for pack codes.

  • Don't know why VM are still masking the names of those new channels, when it's almost obvious what they are.

    If my post is in this colour, it is a moderator decision. Please abide by it.

  • Ok, the number of fields has been increased to 12 for this update. The extra code resulted in a smaller database file size, the oddities of compression when handling larger volumes of data. One to think about next time a Freeview multiplex squeezes in an extra stream...


    12 is a strange number and this will be reviewed at a later stage and possibly increased.


    VM had used legacy pack codes with both the SD and the 4K versions added. The 4K ones being redundant as 4K boxes are able to use the SD code. The morning update removed the SD codes, leaving the 4K codes. All of this was redundant as 1) the (FTV) override flag is set, 2) the slate isn't accessed directly but via SDT linkage from other SIDs, so the other SID's pack code will apply and 3) the slate is unencrypted. So yeah, welcome to the Twilight Zone!!!


    The coders didn't change the pack code lookup in line with this madness, the lowest resolution detected will continue to trigger the pack code. Eg. XL/Full House will be listed as XL/Full House SD, even if the HD and/or 4K versions are also present

  • Don't know why VM are still masking the names of those new channels, when it's almost obvious what they are.

    No clue, there's more of that in the other summary tables but they are held back while the analysts hunt for other VM spanners found in the works...


    "Rekrap Yeson": the SID for the "nosey parker" app has been extended to the NIT configuration of all regional networks.

  • The remaining tables carried over from yesterday should be posted by this afternoon.


    The most recent overnight scan data was far less chaotic. Sky Greats HD morphed into Mission Impossible, there were NIT linkage updates on internal networks and VM has corrected a couple of things picked up on a couple of yesterday's reports (which haven't yet been published).


    The overnight summary will be posted with the rest of the updates from yesterday, other than NIT linkage changes, which will be added to the weekend update.

    It is worth noting that the "Channel Update" services don't exist in the PAT/PMT so don't behave quite like normal channels. The SID number allows these channels to link to specific EIT (EPG) details. All of the channels are mapped to SID 1402 "Lifestyle Slate" using SDT linkage with the Active Hours redirecting the channels to the slate at all times.


    Because of the complexities of the recent changes, auto-matching has now been enabled for these sections of the Scanners Analysis - usage is (currently) optional, with manual matching still in place for analysts who prefer this method. Auto-matching does save a lot of time but, to get at the SDT linkage analysis, the Scanners Analysis now needs to go through 3 processing stages.


    # The tables indicate that SID 1209 "Dummy 1209" shouldn't need to have SDT Linkage or Active Hours set. These both of these sections had been removed by the time last night's scan was taken.


    A summary of the CDS / Frequency changes and of last night's changes will be posted by the end of the day.

  • What's the TRIALS JJ20X?

    I don't know how many of the trials networks are active, if any. They seem to update things such as NIT Linkage data more slowly that the regular networks and regions. The frequencies will change, regardless of whether it is in use or not, along with other networks fed from the same headend.


    They don't seem to be used to test new services, which are only added to the NIT of a few specific internal networks. If I remember correctly, the Manchester TRIALS network carried a few of the new / test services but it was rolled up into the new Wrexham network, so won't in future. I think the NID of the former Leeds TRIALS was used to create the VM Hammersmith internal network at Hook.

  • What's the TRIALS JJ20X?

    It was one of the areas that they tested new software etc before releasing onto the wider network, but Spiderplant on Cable Forum would know for sure as that's directly his thing.

  • JJ, question from me. In your latest info, it says HD version for the new A and B channels, have you noticed any SD versions of these?

    Almost the same thing I was wondering. JJ20X, you mentioned seeing the SD versions or A and B a month or so ago and when they reappeared they seemingly weren't there. (At least that was my interpretation of what you wrote.)
