4.2.2 with skystar2 usb

**aikon0029** · 16-11-2006

Hi guys, can anyone advise me if 4.2.2 feeds can be received on skystar2 usb [ with progdvb] if yes, can they please let me know how to go about it. I have looked thru the threads on the board but cannot see anything. However if I have missed it please let me know where it was, or anyone using 4.2.2 do I need to add any extra software, your help would be very much appreciated, thanks.

that's indeed a good question...
would love to know that too.

For a 4:2:2 feed you need the Elecard codec installed on your machine. Personally I use DVBdream and simply select the Elecard video setting with overlay video to view 4:2:2 feeds. There is a elecard version of ProgDVB - which I assume allows 4:2:2 feeds to be viewed.

**Llew** · 21-11-2006

Yes, Elecard works fine on ProgDVB for resolving 4:2:2 feeds. Only downside is that many of them are now encrypted.

so does it definetly not work with cyberlink, nvidia, etc? that would explain why i never had any luck when trying to watch the odd 4:2:2 feed

(uninstalled all traces of elecard codec as my system can cope with better codecs)

**Llew** · 23-11-2006

Not a question of whether your codecs can cope with 4:2:2. If the feed is encrypted in a system that can't be resolved using methods available to the casual hacker, you will be out of luck.

Thank you for your reply sorry its a bit late, but now I know where I stand, thanks.

obviously mate, but my question is exactly if elecard can decode 4:2:2 FTA whilst other codecs (like the ones mentioned) can't

**Llew** · 25-11-2006

Your original question quoted 4:2:2 feeds in general, not specifically the FTA ones. So obviously I replied to the effect that many of the feeds are encrypted.

Dunno about other codecs. Don't use them.

**kamaleon** · 26-11-2006

gosh. never thought it could become this complicated...
when i mentioned codecs, i thought my question was clear and only referred to codecs, not encryption.
The reason why i ask this is because i've read that the 4:2:2 chroma subsampling used in professional video encoding couln't be properly decoded by most of the common codecs one uses on one's pc like cyberlink, nvidia, etc etc.
I take this info from
http://www.scaistar.com/guide/feed/feed08_e.htm
I tend to think that this guide might be a bit out of date, so that's the reason why i was asking this here on the board. It has nothing to do with encryption. I am perfectly aware that a lot of feeds can be FTA and a lot of them encrypted, whether it be viacess, RAS, BISS, or any other encryption system.

I tried out a few codecs last night, and the FFDshow codec also decodes 4:2:2 (tested on the Burnley / Leeds match). So if your elecard codec expires then I would suggest using FFDshow.

**Lancelot** · 29-11-2006

Strange......I use a very old version of ProgDVB with the supplied codecs, and have never encountered problems with 4:2:2 at all.What exactly are you thinking you should get but aren't, I wonder ??L.

***BGonaSTICK*** · 29-11-2006

Yes, but has anyone tried it with the Skystar USB, as asked by the original poster?

My USB is boxed up at the moment and all the drivers etc. uninstalled, otherwise I'd try it.

4:2:2 ceretainly works on my PCI SS2 with elecard, though sometimes a little pixellated due to my CPU not quite being up to the job (I presume).

Well that wouldn't be surprising, as AFAIK the default codec supplied with Prog is elecard...
I haven't tried getting the odd feed in 4:2:2 since a while ago, and i can't remember exactly which codecs i was using, but i know i haven't used elecard for a wee bit (me thinks it sucks big time)

Are you shure this would make any difference? dunno why but i always thought ss2 pci or usb were both using the same components...

**kamaleon** · 29-11-2006

well i tracked 7E a while ago, had a reinstall of elecard and dscaler codecs (they're reported to be able to decode 4:2:2 on scaistar.com's site), managed to tune to 2 feeds with my skystar usb on my lappie but image couldn't decode properly...

got all blocky and no sound as if i had really bad reception... though the level was 47%... so go figure out. I will try it on my skystar 2 pci nexte time, when i get my new cpu and ram.

***BGonaSTICK*** · 30-11-2006

My SS2 PCI is rock solid, but my SS2 USB is a bit sucky sometimes (pixilation, freezing, jaggy frame rate, whatever). Not to do with sig. strength or quality.

There's definitely a lot of differences in real world operation between the two devices, and they do have different drivers, so I'm not surprised. USB 1.1 don't like mpeg-2 HD either.

On 4:2:2 or just plain 4:2:0?
I can second that though, the tuner is definetly not as sensitive, and i do get a lot of times when i loose signal for 1 min or 2 (then it comes back). But i thought that had to do with the usb controller, not with the tuner/chip on the card itself.
Anyway, as you said, my pci ss2 is rock solid too compared to it.

they do have different drivers, so I'm not surprised.

do they really?

USB 1.1 don't like mpeg-2 HD either.

well yeah, usb 1.1's not enough bandwith for mpeg2 HD... apparently not for some high bitrate SD channels either (never had that problem myself though).

***BGonaSTICK*** · 01-12-2006

Never tried 4:2:2 on the SS2 USB.

4:2:2 on my SS2 PCI card is a bit glitchy sometimes.

4:2:0 on the USB can be a bit pants - I think this could be down to certain symbol rates (the Kiosk channels on 1W were the worst I seem to remember - that's how long it's been back in it's box!), but could just be due to overall USB bandwidth as you mentioned.

I think the chipset etc. is the same as the PCI version, so generally I would question whether the USB factor has a negative influence on overall performance. Clearly this is going to be a problem for HD.

It all adds up to a few differences though, that was really all I was trying to get across.

Yes, the drivers are different. The installer detects which device you have and responds accordingly. Haven't tried the latest drivers, but no reason to suspect that this has changed from the older driver sets I've played with.

There's a thread of mine on here from years back detailing the differences. I was having trouble getting a DiSEqC 1.2 plugin for the USB, which MiBi has subsequently released.

Which ss usb do you have BGona? the first version, 12v, metal, squared box, or the 5v, plastic, round edged one?

***BGonaSTICK*** · 06-12-2006

The first one. I'm an early adopter

**kamaleon** · 06-12-2006

ah! great! that's good to know. I might ask you some more stuff about your box at some point, to try to understand if there are any major differences between yours and mine (the 5v one)

**kamaleon** · 11-12-2006

Say, Bgona, can you watch mpeg2-HD with your elecard codec? I can't, it's unbearable. I'm asking 'cause the other day i was keeping an eye out for 4:2:2 feeds on satelliweb in order to test them and some of the claimed 4:2:2 were HD mpeg2 really but elecard couldn't display them. I don't think they were 4:2:2 just HD.

Another question: have you ever seen any HD around in 4:2:2? if so, is there any codec capable of doing this (whether mepg2 or 4)?

mikeysat · 11-12-2006

Kameloen,

I have just installed prod dvb and followed the big teds idiots guide. I am watching a 4-2-2 feed at the moment and its fine.

Is there a transport reader i can use with prod dvb?
