IPC6023 - Advanced Diagnosis

Hi All,

 

IPC6023 is the youview error code for insufficient quality  on an Internet channel. This is caused by two possible scenarios:
  1) No multicast packets received for 5 seconds
  2) More than 5 packets per second lost (This Message can be enabled using "Picture Quality Alert for Internet Channels" setting)

 

Diagnosing this issue can be tricky as it is either:
  1) A network wide fault affecting all users (very rare)
  2) An exchange wide fault affecting users on the same cabinet (rare)
  3) An individual line configuration fault (rare but has been seen before)
  4) Network problems within the home
 
They are a couple of things you can do to prove the presence of multicast streams without the youview box even connected however they are not consumer friendly 🙂
  One way would be to attach a laptop to the BT Homehub and use a program called VLC to "Open Network Stream" on the "Test Channel" multicast stream (rtp://234.81.130.4:5802)
  Another way would be to use a program called "TS Reader Lite" with "RTPMulticast.dll" as the source to join the same "Test Channel" (234.81.130.4  port 5802) - This analyses the stream and give a "continuity error" count.

 

These methods can then be used for diagnosing in-home network configurations, power line adaptors etc 😄

 

PS: both these methods require that the laptops firewall is not blocking the above protocols/ports/programs

PPS: These are some of the tools I use personally and this guide is not an Official BT faulting guide 😛

Re: IPC6023 - Advanced Diagnosis

Might be good to make this a sticky (or whatever the correct terminology is here) as it gives a user an immediate & relatively simple check that multicast is being received OK.

Re: IPC6023 - Advanced Diagnosis

Thanks for the useful info Steve. Any customer self-diagnosis tools and tricks are helpful.

 

I already had VLC installed on my PC so just tried it. While it didn't play the picture/sound smoothly (just down to limitations or set up of my old PC I suspect) it is a very useful way of at least proving the multicast stream is still available to the router even if the BT TV box is not playing ball.

 

P.S. Just as useful to BT Vision+ multicast customers such as myself.

Re: IPC6023 - Advanced Diagnosis

Hi,

Hope you can help.

 

I get the error IPC6023 on BT sports channels 507 and 508 and no picture.

 

I have the BT/Humax Youview box cable to the router via an ethernet switch.

BBC iplayer works

The BT Sports ipad app works.

 

Tried your test with VLC player but nothing plays (turned firewall on BT Netprotect off to do this).

 

I use my own router (Buffalo WZR-HP-AG300H) (BT Homehubs 2 and 3 were short of features I needed)

 

Rebooted Infinity modem, my router and the youview box in that order.

 

I had connected my old BT Vision silver box to the network (wondered if this had upset things).

To get the silver box to work with my router I had entered the google public dns server addresses (8.8.8.8 and 8.8.4.4) in the router (DNS 62.6.40.162 is also shown).

 

Have run the BT Wholesale speed test and get 60Mbit/s down and 15Mbit/s up.

 

Infinity line is 01277 xxxxxx (Billericay Essex).

 

I tried the online chat system but got nowhere apart from doing the reboots.

 

I would be grateful if you could look into this please.

 

Kind regards

 

Alan

Re: IPC6023 - Advanced Diagnosis

Hi Alan,

 

The router needs to support multicast and IGMP v3 in order to pass the streams.

 

Have you tried it with the BT Homehub and laptop just to prove the streams into the home?

Hi Steve,

 

Thanks for quick reply.

Cannot ping 234.81.130.4

Direct cable to youview box.

Still get IPC6023

BBC player not playing

ITV player plays

Milkshake plays

Broadband speed still 60/15Mbit/s

Not sure where to go from here
