antdude Posted June 14, 2009 Share Posted June 14, 2009 (edited) Hello. United States' television stations shut down their analog yesterday so today I rescanned (ATSC) in DVB Viewers (Pro v4 and TE) earlier today. However, a lot of my new channels/stations have NO audio! Even DVBViewer Pro v4.0.0.0's status bar doesn't show anything aobut audio (no AC3). Some do work! I rescanned in old T.E. v4.5.1.28 and it had no problems on the same stations with no audio in Pro. I noticed v4.1.1 was out so I upgraded and rescanned. Same problem. I noticed all channels without audio showed audio ID at zero (0) in channels editor. What's up? I attached my exported channel list (renamed some station names since they said "service #" from Pro if it helps. Thank you in advance. Edited June 14, 2009 by antdude Quote Link to comment
antdude Posted June 15, 2009 Author Share Posted June 15, 2009 I tried to upload my 9 KB SupportTool.zip but it said it is too big. This thread doesn't have any file attachments so why is it saying "Select a file. Attachment space used 508.38K of 512K"? Quote Link to comment

Gioxy Posted June 16, 2009 Share Posted June 16, 2009 Have you already tried to scan with TransEdit? (you can find it in the Member Area...) It can do the work a lot more powerfully, especially you can set the time it spend to catch all parameters; my hypothesis is that DVBViewer (mainly sat oriented) analize the stream too quick for cable transmissions or your tuner take too time to tuning a channel (generally speaking this is the explanantion for the missing channels names...)...

I tried TransEdit v3.3.3.0 and a scan all. Same results (lots of missing channel names and no audio in a few) when I tried it in DVBViewer Pro v4.1.1. I attached the exported list as TransEdit333-America ATSC.ini FYI. Now what? Quote Link to comment
Gioxy Posted June 16, 2009 Share Posted June 16, 2009 I'm sorry for such a question, but you don't mention about it... have you tried to increase the Tuner Lock, PAT, PMT and SDT Timeouts to (at least) 5000ms? An excerpt from the Transedit's help: TunerLock Timeout (TechniSat and FireDTV devices only): Specifies how many milliseconds TransEdit waits for the driver to signal successful tuning, after the transponder data has been set. This applies to scanning, not to the Preview function. PAT Timeout: Specifies how long TransEdit tries to read the PAT. If the timeout is too short, TransEdit will receive no data from the transponder at all - the PAT (Program Association Table) is the base for everything else. PMT Timeout: Specifies how long TransEdit tries to read the PMT. If the PMT timeout is too short, TransEdit will get no information about the video-, audio and teletext-PIDs, so that TV and radio channels may be mistaken for data services. SDT Timeout: Specifies how many millisecondsTransEdit tries to read the SDT. If the SDT timeout is too short, TransEdit will not be able to detect a channel's name and its provider - the channel will be diplayed as "Service XXXX" with "Unknown" as provider. However, some channels carry no name, or it is not transmitted according to the DVB specifications. NIT Timeout: Specifies how many millisecondsTransEdit tries to read the NIT. If the NIT timeout is too short, TransEdit will not be able to detect additional transponders. The default values will be sufficient in most cases. However, there might be channels that are transmitting the data more slowly, or other conditions prevent TransEdit from reading the tables in time. In this case it may help to increase the timeout values. But have in mind that it may slow down scanning in general. On the other side you can try to improve the scan speed by lowering the timeout values. ...sure sound rather stange that TE scanning works flawlessy while Pro are so "blind"... BTW, I noticed in your .ini posted file that ALL the channels that have "APID=0" have also "Encrypted=8", but honestly dunno precisely what kind of problem it can indicate... Quote Link to comment

Kat-CeDe Posted June 16, 2009 Share Posted June 16, 2009 Hi, did you try to record a channel without sound and try to demux it or take a look at it with MediaInfo? Perhaps they use an uncommon format like AAC. Ralf Quote Link to comment

antdude Posted June 18, 2009 Author Share Posted June 18, 2009 (edited) I attached a copy of my exported DVBViewer TE's INI file. I entered the AID and set AC3 for a channel in Pro's channels and it worked. I also noticed Pro finds more channels than TE during scans. Sheesh! Edited June 18, 2009 by antdude Quote Link to comment
antdude Posted June 19, 2009 Author Share Posted June 19, 2009 (edited) So any other ideas? Or am I stuck? I also uploaded DVBViewer Pro v4.11 Source Properties if that helps (audio not enabled but that is because TransEdit and scan put audio ID as 0! Edited June 19, 2009 by antdude Quote Link to comment

hackbart Posted June 19, 2009 Share Posted June 19, 2009 Hmm, all my TS Testdumps here are working fine - okay they are quite outdated (made in 2006 when i was in Houston/TX respectively SF/Bay Area), but they work like they should. I'm quite unsure which might cause the Problems thats why i would like to need some informations: 1. load Transedit 2. extract the attached zip under Transponders in the userdata folder, 3. select America ATSC in the list and choose the frequency with the channel which does not play audio 4. press analyze If everything is "fine" you should see the following: What we need is the ES Information of each Service, you can dump the information via save as xml.

Christian I am doing KNBC with its frequency of 605000. I assume that 605 MHz since I couldn't find 605000 nor can I enter it manually. No AID seems to match. Attached. I hope I did it right!

hackbart Posted June 20, 2009 Share Posted June 20, 2009 Hmm, the format identifier is not set like it should. For AC3 it should be 0x332D4341, but in this case it is 0x41432D33. Which means to be correct it is more an 3-CA than AC-3 stream Should be fixed in the DVBViewer as well the other applications. Once the next beta is published you should check that out... I also found some smaller issue which caused a problem with identifying the channel name in the VCT table. The reason was that the serviceid value was not correct, so i compare a channel by using the program_number - which was working on all of my test streams here. Christian Quote Link to comment

Christian 4.2 beta did NOT fix the audio problem or maybe I did it wrong. Attached CSV and XMLs from KNBC4 again. I also included a channels for "service" name (allother channels appear to be correct -- yay, no more renaming). I am not sure who owns this one or maybe too weak since I saw a lot of missing values.

hackbart Posted June 20, 2009 Share Posted June 20, 2009 Can you create a small complete transponder dump (not more than 100mb are required)? You could upload the zipped file on rapidshare for instance. Christian PS: Did you have done a rescan of the channels and do you have a working AC3 codec installed (yes i know this is a dumb question, but we need to excluse possible other problems) ?

Christian PS: Did you have done a rescan of the channels and do you have a working AC3 codec installed (yes i know this is a dumb question, but we need to excluse possible other problems) ? Yes, I did a full rescan (found 42 channels). How do I make a small complete transponder dump? Need detailed instructions. Also, 100 MB is a bit big since my upload speed sucks so it will have to be overnight or something. I have AC3 Filter v1.61b installed from the K-Lite Codec Full Pack v4.9.0. It does work on channels with AC3 audio even though I only have a 2.1 speaker setup. I see the AC3 system tray icon when in used. FYI, I am going to work soon so I probably won't be able to get the dump or whatever other requests until tonight/tomorrow. Edited June 20, 2009 by antdude Quote Link to comment
Lars_MQ Posted June 20, 2009 Share Posted June 20, 2009 I have a better idea. We don't ready need the audio and video streams, just the data streams with all the tables. It should be around 1 maybe two MB compressed. I'll PM you a little plugin for this in a few minutes. Quote Link to comment

I did that already before the release, adopted the Pro code, found another bug in it, discussed the matter with Lars... unfortunately by copying the code a new bug slipped in, well hidden, and since the TransEdit scanner isn't able to read from a file source, it remained undetected. Ok, I'll prepare a new release, and I tell you, that one will be able to scan a file source! Quote Link to comment
