SVR-HDT500 Audio Clicks & Pops

JustinN — Mon, 03 Nov 2014 14:52:23 GMT

Has anyone else noticed that the audio on all HD channels has recently acquired splats, clicks and pops?

I have had this problem on COM7 channels (BBC4HD, BBC News HD...) since they started in December 2013, but recently this problem has spread to PSB3 channels (BBC1HD, BBC2HD, ITVHD, Channel4HD), when they were fine before. The received signal is good, and there are no picture break ups to indicate that there is a reception problem.

The broadcasters have certainly changed something on the PSB3 multiplex mid-October, but what I am not sure about is whether the audio decoding software in my PVR is at fault, or whether it's the broadcaster at fault. Reading on other forums, I know this problem is affecting other makes of PVRs.

Thanks,

Justin.

Hi there

I have the same PVR recorder, however I have not used it in a while - I'll get back to you when I test it out and see if I also experience this issue (however it wont for a couple of days).

Also, you say about other forums - I dont suppose you know if everyone is on the same transmitter - as it could be a simple case of a 'rogue' transmitter.

Cheers

I receive my signal from Emley Moor transmitter. Other people who are now complaining about this problem, from at least one other transmitter and recorder make, are to be found here: https://www.avforums.com/threads/digital-stream-dhr-8203-5u-hd-pvr-master-thread-part-twelve.1686714/page-42

I made a thread of my own - https://www.avforums.com/threads/psb3-mux-audio-clicks-and-pops.1914401/#post-21319523 - in which I indicated that the problem has coincided with some form of transmission change on PSB3. On this thread I have also posted an example of what I hear, although I inadvertently reduced the clarity of the splutters and splats.

This problem is either a broadcaster or receiver software fault. If it's a receiver fault, I really think Sony should fix it because this problem first started when my recorder was only 2 years old, so I don't think I have had full use of it before it has been rendered obsolete by transmission changes.

Thanks,

Justin.

Hi there

I have had my HDT500 on HD channels for the last couple of hours now, with no incident. However no channels have been broadcasting 5.1 as of yet (only 2.0 stereo). So cannot test this on mine. However I have been reading the other threads that you linked to, and I can see that many are complaining across many different devices and manufacturers - therefore this is unlikely to be specific to Sony.

PS : Im on the Oxford transmitter.

Cheers

I don't know if 5.1 audio is a factor in this.

From the other threads, I gather that engineers for Vestel and Digistream recorders are looking into the issue. It'll be interesting to know their findings - either the broadcaster has violated the Freeview HD specification, or my PVR doesn't meet it.

Thanks,

Justin.

Hi there

As another person has also reported the problem:

http://community.sony.co.uk/t5/general-chat/svr-hdt1000-audio-dropouts-issues/m-p/1830063

I have reported this to Sony in the hopes that they can assist in resolving this.

Cheers

I have also noticed this. I did notice it some time ago but mainly on channel 4 HD. It seems to have spread to all HD channels. It is getting rather frustrating and putting me off using the device. Please fix Sony.

It appears the problem is being caused by broadcasters switching from Dolby Multistream 10 to MS11. Sony probably already know this.

Now, whether the fault is caused by the broadcaster poorly formatting the MS11 data, or the software in our recorders is faulty, always was faulty, and is not capable of ignoring the additional data when it should be able to, I don't know.

Hi guys

Received a message from Sony that they can confirm the problem, which means that they can replicate it too. So good news so far.

Ill keep you posted when more updates comes to light

I would also be interested in the (hopefully software) solution to this as it has started to dominate all broadcasts and is really annoying.

Hi all,

Just wanted to add that I also suffer these symptoms on my Panasonic Viera TV and likewise my Panasonic HDD/DVD Recorder. I only receive standard Freeview, not HD but same problems either way. I've always put this down to atmospherics, rain/wind etc etc.., even birds roosting on aerial perhaps?!

Hi guys

I have requested an update from Sony on this issue. Hopefully they have some insight in this problem.

Cheers

I think it's the broadcasters causing this issue or the transmitter stations. Earlier this evening I was watching my mother's Panasonic Viera TV, she has Freesat and we suffered the exact same trouble. We were watching BBC One News at the time and they were showing an outside broadcast filmed on location and we suffered several audio clicks and pops together with a picture breakup pixelization of faces.

Hi All

Received a little bit of feedback today in regards to this issue.

In a nutshell, SonyUK has been in discussion with DigitalUK and Arqiva who have provided Sony with information. This information has now been passed to the engineers in Japan in the hopes that they can find a solution. It does appear to be the encoding of the broadcast stream that is the problem - but know no technical details.

So, unfortunately its a waiting game at the moment.

Cheers.

Is there any news on a software update being developed or deployed for this PVR? I know of two other makes of PVR - Vestel and DigiStream - that have had updates to correct the ongoing audio problems on all HD channels.

Thanks,

Justin.

Hi @JustinN

Just to keep you informed, I received some feedback that a fix is in the process of being developed. Unfortunately there is no ETA on when this will be rolled out.

Cheers

Given the time that has elapsed, are we to assume that Sony have no intention of ever fixing this problem?
