Multicast channels down

All Multicast channels including BT Sports are blank at the moment.
I believe it has been reported (see BT Vision topic).

Just been fixed - back to normal.

HD Multicast channels - 5.1?

I'm returning to BT TV after a stint with the enemy. Beforehand, I was trialling fibre multicast with the Vision box. The HD channels were sadly lacking any kind of 5.1 of either the Dolby or AAC kind. Now I know that the FTA HD channels on YouView will have AAC 5.1, but do the Extra TV HD channels come with any kind of 5.1 stream?

Hi, yes....some are better then others so there is still quite a lot of standard DD2.0 audio broadcast but some do send DD5.1 and it seems to be on the rise. The BT Sport channels do a fair bit and there are a couple of the extra channels that seem to do 5.1 quite a lot.
Not sure which ones of the top of my head but I will have a better look tonight when I am home and report back...

Multicast channels with optical sound output?

Success the channels have appeared finally. Ican not get sound through my sound system however which is connected via optical cable. The normal channels are fine but not the multicast. Obviously this is a pain in the backside meaning i have to turn the tv speaker on for the new channels and off for the freeview ones.
I think i read in a thread it was a known fault but can anyone confirm? Is it supposed to work but hasn't yet or is this the way it was planned to be?

id imagine given all the recent problems it will be delayed. Im not going to bother watching them until its sorted as i just cant be bothered switching the tv speaker on and off with every channel change
Hows about using the phono outputs in the meantime? It's not as if the box does 5.1 yet which would require the optical. It would save you switching.

LACP port-channel down but Individual ports up

I have setup an active LACP consisting of two members in each port-channel. As it is configured now the individual ports are operational but not participating as members of the LACP. Not finding any reference to exactly why this is. From what I can gather this may be related to the host configuration?
If anyone can enlighten me to such a situation it would be greatly appreciated. Would be even better if anyone had experience with the Oracle Database Appliance requirements for network configuration on the Cisco side.

Hi,
Putting the EtherChannel to the "on" mode will force the ports to become bundled unconditionally but the true problem, then, is truly seeing if it works. The Cisco switch will happily keep the ports bundled and will even transmit data over these ports but how do we know if Oracle is happy with that and does the same?
Personally, I would not recommend using the "on" mode precisely because of lack of any indication that things are operating just as they should, unless it can be shown without doubts that Oracle runs without LACP and uses a static EtherChannel.
Best regards,
Peter

Multicast Channels Sound Drop Outs / Picture Pixel...

Had this issue for months now and its totally unique to broadband channels. Its been a problem since leaving sky and joining BT in august.
Had around 5 engineers out who all say "Im the wrong type of engineer for this job, all i can do is check your broadband"
Sound just randomly drops out and picture quality on ondemand such as kids is getting noticeably worse.
Im on BT Infinity and get 79Mb DL which im told has no errors whenever an engineer checks however the guys on the phone tell me they can see my line is losing packets. line correction has been applied and my speed was halved to 35Mb! This did NOT fix the problem.
Watching channel 4 HD at the mo and if im being honest its like the kids have the remote and keep pushing Mute.
Had a REIN test and nothing is interfereing
Im at the end of my tether
Oh and Both Box AND router have been swapped out
Its a Black BT Vision Box and BT Home Hub 4
Anyone had this issue and got it fixed?

I wonder if the issue might lie with the HH4. Do you have an HH3 to hand or could you borrow one to try?
I know that is not very helpful. The only other thing might be to swap to a YouView box.
I assume you have tried different ports in the HH4?

Is it possible to turn down the D channel on a Qsig trunk

We're working with a mgcp controlled 3845 and a mgcp controlled 6608 blade in 6509 switch. We're connecting to a Nortel PBX using Qsig trunks.
We're testing failover for calls from the Nortel system over multiple Qsig trunks to the 3845 and the 6608, i.e. if the Nortel see the trunk is down it will hunt to the next trunk.
What the Nortel engineers are requesting us to do is to turn down the D channel on a trunk from the 6608 or the 3845 to the Nortel PBX to see if their equipment will hunt to the next Qsig trunk if it sees the D channel down.
Thanks,
Jim

On the 3845, go to the interface serial and do a shut down to bring down the D channel. For example, if the T1 is connected to port 1/0, then do the following
interface serial 1/0:23
shutdown
On the 6608, if you are connected to port 5/1, then disabling that port will bring down the D channel. Use this command
set port disable 5/1

BBC/ITV HD etc. down the Phone Line vs Over the ai...

Hi,
I've just had BT Infinity and prior to this I had and still have a Black BT Vision box and hadn't really realized I would get so many channels including HD channels down the phone line.
I'm curious though, how does the HD picture quality down the phone line compare to when compared to receiving through an aerial or satellite dish?
Which is best and which is worse?
Also, I upgraded to BT Infinity as Skype video calls would always drop out on my laptop after a bit when on BT Broadband using the HomeHub2. Sometimes I had to restart my computer as the dropout would also knock out the internet too and restarting it seemed to be the only way to bring it back. I experienced the same problems both with a wired connection and a wireless connection to my laptop.
Unusually if I try making a Skype video call using Wi-Fi using my mobile phone, the video call never dropped out.
Despite upgrading to BT Infinity and using the HH5, I'm still experiencing dropouts with Skype or receiving poor video and/or audio with it.
Could this therefore be a problem with my laptop or some settings or something?
If it could be laptop settings, could anyone advise me what settings I can change and how I can improve things?
Kind Regards and Thanks.

There are a few factors that determine picture quality. Resolution, aspect ratio and compression being three main ones.
Freeview SD channels have never all been equal. They all tend to transmit 576 vertical lines, but horizontal resolution can vary to save bandwidth, 720, 704 or 544. Some also use higher rates of data compression to save bandwidth which usually results in a more blurred or blocky picture at times. 4:3 aspect ratio pictures can actually be better defined than 16:9 ones as the latter still use the same transmission resolutions but are stretched out by the TV or box. Some sneaky channels at times use a 16:9 or 14:9 window in the centre of 4:3 picture as black bars compress very nicely and save more bandwidth. The box or TV then sometimes zooms in as appropriate. The resulting picture is usually pretty rubbish.
Freeview HD channels normally represent 16:9 pictures and initially were transmitted at 1440x1080 (4:3) and stretched out. However, I believe they are now transmitted at 1920x1080 which is proper 16:9 (maybe someone could confirm this)? They use more efficient data compression techniques and transmit at a high enough bandwidth to look pretty great.
BT TV multicast SD channels look to me as though they are transmitted at 720x576. Not sure if they still sometimes represent a 4:3 picture when appropriate, but most modern TV content is now 16:9. The compression rate seems low and as the previous post says, compared to Freeview SD they look as good as (if not better than) the best quality Freeview SD channels such as BBC 1. I used to get Sky Sports and ESPN in SD via the TV aerial and the multicast SD versions definitely look much better.
Note: When I view the test channel 475 on my PC using VLC Player it says that channel is at 544x576. I'm guessing this low resolution only applies to the test channel though I have no way of checking on the BT Vision+ box?
BT TV multicast HD channels look very good. Again I have no way of checking the resolution, but I'm guessing they are at 1920x1080 with an aspect ratio always set to represent 16:9 pictures. The compression rate seems as low as the Freeview HD equivalents. I can't really see any difference between the Freeview HD and multicast HD channels on my Full-HD TV. All very high quality.
In simple non-tech speak. SD pictures are better than Freeview, and HD pictures are just as excellent.

HD Channels freeze after 5 minutes

Since the launch of BT sport my HD channels including new BT sport freeze after about 5 minutes. Help suggests I restart Home Hub and BT vision box. This gets the system going for the next 5 minutes. Note this is the behaviour whether accessing BT sport or BBC1 HD. I can actually get the channel to unfreeze by simply changing channels so its not really necessary to reboot all the boxes. Unfortunately this approach does not work when trying to record your favourite football team.
Other details: BT Vision box is connected to Home Hub by powerline adaptors and I often get a message with error VMC999 complaining of a slow connection.
What is particularly irritating is that I have a new Samsung smart TV which displays all HD channels perfectly (via Freeview) and seamlessly streams HD on demand content by connecting wirelessly to the BT router.
I have made two attempts this week to contact BT (0800...) but abandonned them as there are'nt enough hours in the day.
So what I propose do is to "enjoy" my "free" BT sport channels (I have infinity account), cancel my BT Vision subscription (if BT ever pick up the phone) and subscribe to Netflix, Blinkbox, etc.
If anyone has any practical or technical suggestions please comment.
Mike

Did you manage to try using an ethernet cable rather than the power line adapters (PLA's)? Did this solve the problem? As others mentioned the PLA's are probably causing the VMC999 error. You need a reliable connection to the Vision+ box for the multicast channels to work smoothly. Being live channels they have to work in a slightly different way to on-demand content.
If after trying a cable you still get the multicast channels freezing after approx 5 mins every time you try to view/record them then you are not the only one. In that case I suggest you read this thread I created a while back. I got it fixed for my line, but it still seems to be affecting some customers now. Get your stopwatch out!

Lost HD & Sport channels on black BT Vision box

Hi, I was advised to do a factory re-set on my black BT Vision box because it was performing so poorly but since doing so I can no longer get my HD or sport channels (BT Sport 1 & 2, Sky Sports 1,2 & 5) back.
Prior to doing the reset I only had the HD & sport channels as I had such a poor aerial in the roof. Doing the factory re-set meant I had to have a functioning aerial to re-scan for all the channels so I fixed the aerial & whilst it means I can now get all the freeview channels I can't now get any of the HD or sport channels back that I pay for!
BT initially thought it was an issue at the exhange but having gone through several re-sets, re-scans, re-registers & re-boots they've finally agreed to get an engineer out.
In another two weeks time!
Anyone got any suggestions as to what might be causing this & therefore how I might be able to fix without waiting for the engineer visit?
thanks

Either the entitlements are missing or you are on the wrong version of the software. This can sometimes happen initially after a reset.
What does it say for Help & Settings > Settings > System Information > BT TV Release ?
If it ends in C (such as 8.7.1C) then you are on the version for using a viewing card.
If it ends in E (such as 8.7.1E) then you are on the version for multicast channels over broadband which is what you need.
If on the C version then try the following.
Help & Settings > Settings > System Information > Reset Registration
Help & Settings > Settings > System Information > Check for Upgrade
In my experience that usually encourages it to download and install the correct E version again.

Audigy 4 Pro - can only get 2 channel sound via SPDIF/optical connecti

I have two PC's, one with an Audigy 4 Pro and one with an Audigy 2 Platinum (A2P), I have my 5. speakers hooked up to the A2P and the A4P connected via the SPDIF to the A2P, I would expect to get 5. - both are setup to use 5. speakers, (I know that as a standard Digital coax/optical connections should handle multi speaker configs my entire A/V sound system (7. Dolby) uses optical and coax and it works fine).
If I run the channel test on the Audigy 4 I can get nothing but sound through the left and right speakers, if I run the test on the Audigy 2 (speakers direct connected) the sound is fine, if I reconnect the speakers to my Audigy 4 I get sound on all speakers so it looks like its an issue with the SPDIF and optical inputs (I tried both).
I have emailed tech support, I'm waiting for them to come back and tell me that the Audigy 4 cannot transmit more than two channels down the SPDIF/optical outs, thats my suspicion anyway, if that is the case then I'm not going to be a happy man and the Audigy will be going back to the store. Could be a driver problem of course as I cant believe they would implement Dolby and THX and only transmit two channels on the optical outs, that would be a bit dumb considering the primary use for digital connections is sound system interconnects.
Anyone with any ideas about this let me know, perhaps theres a hidden setting somewhere or a registry setting that switches the digital outs to carry all signals.

Just before everyone kicks off, heres a response I got from a tech guy at Creative themselves.
If you connect speakers to your sound card using a digital cable
(RCA/SPDIF or optical) then the software speaker test will only output
from two speakers. The reason for this is that the speaker test signal is
not in AC3 nor DTS format.
The signal on a digital connection is either
Optical SPDIF - which is either Stereo PCM signal or AC-3/DTS Bitstream
RCA SPDIF - which is either Stereo PCM signal or AC-3/DTS Bitstream
If you play AC3 (Dolby Digital) or DTS encoded signals, the amplifier
decodes this and outputs it to all 6 speakers (5 satellites & subwoofer)
discretely.
When playing back stereo signals (such as Wav/CD Audio or MP3/WMA files)
the amplifier may generate 5. output based on the incoming stereo PCM
signal, provided Dolby Pro Logic decoding is available and activated.
Therefore the speaker test should not be relied on when using RCA or
Optical digital connections.
This applies to all speaker systems equipped with RCA or Optical digital
connections.
This makes sense to me and I'm pretty happy with it, basically as the reply says above the speaker test does not encode to AC3 hence if you hook two Audigys together and run the test you only get 2 channel output, if you play a DVD which is AC3/DTS encoded on one Audigy and listen to speakers hooked up to the other when both Audigys are connected via SPDIF or optical you should in theory get full playback on all speakers. Hopefully
Cheers

Receiving channels 225 et al

Not sure if this question is related to the massive Multicast thread earlier (much of which is all g(r)eek to me, I'm afraid) but I'm surprised that I still can't receive the channels 225 and upwards. I still get a message saying that I do not have a compatible Freeview HD device. I do have a BT Youview box, Infinity and HH4.
I had assumed that this problem would be solved when my Youview box was enabled for multicast, which it was on Aug 1st. I can receive the BT Sport channels fine, in HD too, and the extra multicast channels are all listed (though I haven't subscribed).
So what's different about channels 225 et al? Are there already different multicast standards out there?
Solved!

Those are nothing to do with YouView, BT or Multicast. They're channels designed to work on internet connected Freeview boxes and use technologies not supported by YouView.

Dlsw using port channel

I have 2 dlsw router at head quater office, named dlswA and dlswB.
From branches router, dlswA is a primary peer and dlswB is a backup peer.
Both dlswA and B have 2 fast ethernet interfaces.
The current configuration of dlswA and dlswB are 1 port as IP port and other port as sna/bridge port.
With this configuration the problem is when SNA port at dlswA problem, then dlsw circuit will have the problem, because dlsw peer from branches still connected to dlswA.
if I configure 2 fast ethernet port become a port channel. And configure IP and bridge group at port channel interface (IP and SNA at the same interfaces), so when the port channel is down, then branches will connect to dlswB as a backup peer
Are the port channel configuration will solve the problem ? How about the stability of this configuration?

Thank Matthias for your reply.
Both of head end routers are on the same vlan and the host is using same mac address.
As far as i know if from branch have 2 active peer with cost setup, there will loops posibility because both head end routers are using ethernet with same vlan and same host mac address.
I test the port channel within my LAB using netbios, seem works as expected. when single port at port channel down, branch circuit still remain at dlswA router, when all port channel member down, the branch peering move to dlswB.
Here are the config:
hostname dlswA

Using "Channels" to extract

How does one use "Channels" to extract a portion of a photo for use in another piece? Thanks!

it all depends upon your image. When you use channels, you want to pick a channel that has the most contrast where you want to make the cut out. Drag that channel down to the new channel icon to duplicate it. Then you can use levels or curves to increase the contrase. Painting on the channle with a brush set to overlay with either black or white can also help refine the edge. Once you're happy with what you have, you cmd/ctrl click on the channel icon to turn it into a selection, which you can then use to create a layer mask.

Copper multicasting - what is actually going on

Hi my area is due to be upgraded to FTTP later this year thanks to BDUK. I've just been checking the BT Wholesale checker and over the last 72 odd hours since i last checked COPPER MULTICASTING has appeared to be active on the cabinet. Now i understand FTTC/P multicasting for stuff such as SkySports and the extra Vision channels but what will ADSL multicasting allow me to do or is this for some future unannounced service? At present i have Youview from BT but ovbiously i cant have BT Sport or the extra channels due to lack of infinity.
Thanks
Ben

Don't forget that the BT Wholesale Checker is showing which services are available through BT Wholesale to all ISP's. It is up to individual ISP's whether or not they pay BT Wholesale for particular services and package them up for sale to customers. One such service is TV Connect.
This article from early 2013 mentioned that as well as the fibre multicast version BT Wholesale were looking at launching an ADSL2+ copper multicast version of TV Connect as well. See paragraph 4.
http://www.thinkbroadband.com/news/5800-bt-tv-connect-service-to-carry-live-tv-channels-over-wbc-net...
So I would guess that the Copper Multicast for your line means that, in conjunction with OpenReach, BT Wholesale have made that service available to ISP's in your local area. Whether or not BT Retail pay for it and offer it to customers is another matter.
As has already been mentioned, a limited number of BT Vision+ box customers have been receiving the live Sky Sports, BT Sport and ESPN channels in just SD over ADSL. I believe it was only done where multicasting had been set up by OpenReach and they certainly had to upgrade their BT Vision+ boxes to the multicast version of the software. Does that mean that BT Retail are already using the TV Connect ADSL multicast service? I don't know the answer to that as BT tend to keep these things close to their chest, but it does seem likely. Of course that wouldn't mean they have to use the same service for any BT Sport solution for BT Youview+ boxes on ADSL lines.
I receive fibre multicast channels over FTTC Infinity. The results for my line now includes the following.
