BV7-40 MKIII - what happened to the SD pixelisation fix?

38 replies
Moxey, i have had the same problems with my BV7MKIII, ie. white flashes etc. which i have had since Dec 07. I have informed my dealer who is looking into the problem for me. You mentioned that since your software upgrade the curtains take longer open when tuning into Sky. On my set the curtains only open when turning on to DVD or digital freeview, when turning on Sky the curtains do not open but the picture just appears in one go. Was the same thing happening to your set before the upgrade or is this a fault with my set.

No, that wasn't happening. On Sky HD the curtains appear. However, it does take a LOT longer for a picture to appear, after switching on the TV (ie. pressing 'V.MEM'). Sometimes I think there's a problem as it takes a lot longer to appear. It's the same on Sky as it is on the DVB-T, although Sky takes longer to appear on-screen. It's about 12 seconds from pressing 'V.MEM'! It feels longer.

So, white flashes on DVDs, gone. White flashes on PS3 in 1080p mode, present. However, this is a 1080p TV, so it's going to auto-default to 1080p mode and I don't want to view it in a lower resolution simply to avoid the white flashes. That was a reason for purchasing the MKIII.

On a sidenote though, Sky HD never showed the curtains on my old BV7-32. The picture went straight on and off.

Cheers, will have to call my dealer in the morn. I also had a BV7 32 which the curtains did not operate on sky, however on my new set they only work on Sky when switching off. Also the STB controller is not switching the Sky box off. Have tried all settings but no joy, looks like my dealer will be busy!

I don't bother getting the controller to turn off the Sky box....as often it doesn't turn it on, either! Often I'd have to manually switch the STB back on and, now it's situated on the wall behind the TV, it's almost impossible to turn on/off manually, without knocking in to the TV.

Best let the box auto-manage it's own sleep and it will sleep after a period of time, then come back online when required.

BTW, sorry if I wasn't clear....when I said 'a LOT longer', above, I meant since it has been upgraded to sw 4.01. Sky HD used to start immediately - within a couple of seconds of pressing the button on the Beo4. Now it's around 10-12 seconds!

You didn't read the thread - it's from the Playstation 3. Others experience the problem with Blu-ray playback.

Also, the other problem isn't HDCP handshaking as before the sw update Sky was displayed in around 2 seconds, wheras it's now around 10 seconds.

If the set top box is connected to the TV using an HDMI cable, the connection time is longer because of the handshaking protocol required. Concerning the pixelisation problem, no software upgrade in the TV will be able to solve it, as this is clearly a symptom of overcompression of the original signal by the cable company. An image processing algorithm cannot recover information that was not present at the beginning.

Customers should complain to the cable company, especially for sports channels where compression issues are clearly visible. A properly encoded digital SD signal should be of DVD quality.

Why is the connection time longer? and why is it that with every other product  that uses HDMI there is no issue. The 'handshake' takes about 1 second! 

 

If the pixelisation is the fault of the cable company why is it other brands dont suffer to the same degree??

355f, that's exactly what I've said above (ie. we know it's only an issue with the B&O BV7-40 MKIII).

One thing may help: If the set top box has a pass-through option for the output resolution, it is better to select it and let the TV do the upscaling. Standard resolution channels will be sent to the TV at a resolution of 720x480 pixels and the Beosystem-3 will do the upscaling itself. Upscaling done by the STB is usually very poor: when you look closely at the picture, you can still see the original definition scan lines (more visible on text). When it is done by the Beosystem 3, the text is continuous without lines.

 Regards,

Jean
