hello @all,
the "OOBE" with VOMP was very positive -
it's a quality product already!
i'd like to point out these possible bugs and wishes:
- the main-menu clock doesn't get updated
- pressing the green button and selecting "Standby" apparently doesn't
trigger the same event.
[my telly switches on and off with the SCART signal. however, it only
stays off if i select "Standby". with the green button the telly turns
off and then immediately back on again (while the MVP stays off)]
- a progress bar indicating how far a running (live TV) programme has advanced
would be _very_ nice (similar to this one
mvpmc.sourceforge.net/images/myth_osd.jpg but doesnt need to be alpha blended)
- EPG info is not scrollable if text doesn't fit into the box
- EPG info should include current time
- changing the channel via buttons 0-9 should accept one, two (timeout
controlled) and three digit entries
that's all for now.
i hope i'm not being presumptuous by posting this.
cheers
Harry
Hi Harry, I am thinking that you might like the next version of VOMP.... :)

Done, done and done. Currently it's in CVS only, but all will be in the next dongle.

Unfortunately this is really odd. Both of these ways of invoking standby run the same piece of code that shuts off the video signal. I have no idea at the moment how it could work with one but not the other.

I have been planning this for recorded programmes but I hadn't thought about live. Maybe this could be done...

Do you mean the programme summary? If so then this is listed as a bug against VOMP already, I will get around to this at some point.

Not at all. The more discussion the better.

What function should this progress bar have in live tv?
a) progress of the actual programme (e.g. 20/45 mins). -> My suggestion is to put that information into the epg-box. (cp. http://www.vdrskins.org/vdrskins/displayimage.php?album=41&pos=1 - posted a while ago here in the forum)
b) in the future a progress bar for the timeshift-buffer (how far behind live-tv?)
Just my thoughts to that.
Such a progress bar would be nice, but I suppose there are more important things to do first.
It is really fantastic to persecute the progress and improvement of VOMP. :-)
Thanks Chris!!! :)

thanks a lot!
i've already taken a look at the CVS repository and saw that there had been
made recent changes.
however... compiling a dongle is not that trivial (or so it seems).
[...sorry for ugly snipping...]

peculiar.
however.. it's not that important.

hehe. i have this feature on my HUMAX DVB-S receiver and have to say this
is _such_ a cool feature.

oops.. yes. you're right.
@Schnurps
yes... (@progress bar) that's exaclty what i had in mind.

A small problem with the current CVS. Tuning to a channel which is not currently transmitting, the MVP locks up and does not respond to any keys on the remote - a power-cycle is necessary to regain control. The previous version would return to the menu after a few seconds when the 'back' key was pressed.
Dave: You are using UK freeview? What channel did you try to tune to and at what time? I have looked through my channels at the moment and I can't find any that are totally off, I just get other channels that share the same space.
I would expect some problems like this at the moment, I have made big changes to the way the program does things so the odd lock up doesn't surprise me. I managed to lock it up on the main menu the other night, unfortunately I have no idea how I did it!
The most recent was "ITV News". OK it turns out I had two lines for that channel in my channels.conf and selected the wrong one - PIDs for that line were 2850, 2851 instead of 550, 551. The other was channel 302 around mid-day before the snooker started.
I have the same problem with Dongle 16.
The German Music-Channels "Viva" and "Vivaplus" seems to be not reachable via DVB-S at the moment, and I have to power down the MVP to get it working again after accessing one of those channels.
I think the same is with our "Kinderkanal" in the night. (not completely sure).
Is it possible to check this and to respond with this "Chanal not reachable"-Box?
VIVA:12670:v:S19.2E:22000:309:310:311:0:12732:0:0:0
VIVA PLUS:12552:v:S19.2E:22000:171:172:179:0:12120:0:0:0

I think I have found this bug now. It seems that because VDR initially claimed that it could provide the channel, vomp was happy to sit in a loop of continuing to request the data. Current CVS code now stops and displays the "channel unavailable" message.

Yes that works fine now, thanks.
hi again!
is it possible to pass the data that is sent during VBI to the telly so one
can browse teletext?
cheers
Harry
I don't think VBI data exists for digital TV ?
it does.
how else would i get teletext over a "normal" dvb-s receiver? *g*
cheers
H
Old style black screen with 1980s (?) look text and blocky graphics?
i see.
you don't think it would be worth implementing.
well... it was only a question. *g*
cheers
Harry
No no, it's not that! I am surprised it's transmitted on DVB. I'm at a loss as to how it is done, or how any of this stuff *could* support it! If you play the vdr file in something like mplayer, can you see the VBI data at the top of the picture? Or is it transmitted some other way?
oops...*gg* i completely misunderstood you..hehe.
to be honest.. i have no idea how the teletext is extracted from the dvb stream and
put into the VBI.
i have to investigate that.
cheers
Harry
Hi,
as far as I can remember it is in a (private) stream of the .vdr. One should have a closer look at the osdteletext plugin to get more details. If you use a card supported by the ivtv-driver (analog!) the teletext can be saved into the TS/PS stream.
In DVB teletext has its own pid-number. This can be easily seen in channels.conf of the vdr.

I know how the new digital DVB teletext system works, with graphics, nice fonts, more interaction, not necessarily page numbers etc etc works. We are definitely not talking about that here?
that is correct.
we're talking 80's block-like screens with a total of 96 letters, digits and special chars.
(transmitted between line 577 and 625 AFAIK)
there's a new form of text embedded in the DVB stream?
didn't know about that.
The teletext transmitted via DVB-T looks the same as the analog one via cable. It is the 80's block like screen. But there exist different versions of teletext. It was extended over the years. What you'll see depends on the teletext decoder of your tv-set or your vdr respectively.
So I'm of the opinion that we did talk about the same.
Over the weekend I'll try to have a closer look on that.
Yours
Torsten
Hi again,
did you think I was talking about MHP? I wasn't.

Torsten
Hi,
here is a snapshot from my vdr.
Torsten
thanx 4 the info.
hmm.. my VDR ist positioned in the cellar... i use it solely for streaming to MVPs.
so , even if VDR is able to decode and display teletext... question remains whether
vompserver can interface with that.
Hah, incredible. As far as I know nothing like that is transmitted on UK-DVB-T. We have MHEG streams which is as I described before, nicer looking fonts, backgrounds, proper graphics etc. So, I would imagine the old teletext data has it's own PID in the TS streams, that could easily be sent to the MVP, possibly easily demuxed by the demuxer (but that would require some work) and then not so easily rendered on the MVP. As they don't transmit it here errr.... someone else could write the renderer ? ;)
renderer?
so... back at the beginning... this text data can _not_ be put into VBI line space?
Well I have no idea how it is transmitted at the moment, but I would hazard a guess that if that data is not in the VBI to start with then no, it can't be put back in. It would involve decoding the MPEG for the picture, making the frame bigger, somehow inserting graphical dots into the top and re-encoding it for the MVP. Then, would the tiny dots of VBI data survive MPEG compression? That is beside the point of not taking all that CPU power on the vdr server.
But, how was that screen shot made? That can't have been the TV rendering the text because you can't take a screenshot of that unless you resort to taking a camera to the TV. So however it is done in VDR could be the way to do it for VOMP.
Hmm, also, another conceptual way of doing it would be to transmit the teletext data as a digital stream to the MVP and have the MVP render the dots using the OSD system. But I very very much doubt the MVP would be fast enough to do that.
I think the problem here is that there are several different systems in use around the world, and everyone assumes that their system is *the* system.
AIUI (and please correct if wrong!) the text systems currently used are:
MHEG-5, used on DVB-T in the UK and Finland. This is an object-oriented approach, using something like XML but encoding the data stream using ASN.1.
MHP, used for DVB-T elsewhere in Europe. Simpler XML-based system.
Teletext as used on DVB-S in Europe excluding UK. This I presume is the one being discussed.
Hi,
the screenshot was made via the xine-plugin from my vdr.
In fact the teletext analog and via DVB-T are identical. Additionally there is a MHP Stream on the DVB-T Channel.
BTW
The osdteletext plugin uses a kind of teletext server which caches the pages on the vdr. So you are able to read a teletext page of a different channel or access the pages very fast. Unfortunatly there is no TOP videotext implemented.
Couldn't we use this server too?
Yours
Torsten
