Channel 4 HD - Lip sync improvement?

**Llew** · 15-07-2008

Since today's pid changes on CH 4 HD (kingofsat updates) doing a preliminary check on this channel there appears to be a distinct improvement in lip syncing. I'm using version 1.00.11 firmware.

Can anyone confirm this?

I can't BTW find which pids have changed, the apid is still the earlier one.

Update - I have loaded v.1.0016 and now have video with synced audio on CH4 HD too - absent before the pid update. Should be OK with v.15 too. Audio though seems to need half a minute before the lag 'catches up' with the video.

Some picture jerkiness at first (I'm using a Dragon cam). Going to another channel and back again seems to cure it.

I don't believe it, I still had sound but no picture last night.
I put my $ky card back in my $ky box to update it earlier this evening, then put it back in my Humax and I now have picture with perfect lipsync.

I'm we'll chuffed

Phew, that's a relief Michael

As you had sound, don't know what updating the card acheived. All a mystery to me, particularly regarding the pid change episode.

The PCR PID (clock reference) is now the same as the video PID i.e. the clock is embedded in the video stream. I don't know why Sky have done this, but it has the side effect of bypassing the bug in the Humax software, getting rid of the lipsync problem and giving a picture on V15/V16.

Cheers David, that makes sense

Audio on C4 hd is good. No delay. Was watching Deserate Housewives today. 100% good audio
