4:3 stretch to 16:9 based on WSS (1 Viewer)

TV Server TsWriter and TVService log files. Please also specify the names of the channels that you want me to look at. All I would do is check whether those channels have VBI sub-streams which might contain WSS signalling.

OK, thank you. TsWriter and TVService log files are attached.

There are names of channels I would need to check:

• CT1 HD
• CT2 HD
  
• CT sport HD
• Nova HD
• Nova cinema HD
• Prima HD
• Prima cool HD
• Prima ZOOM HD
• FANDA HD
• Barrandov TV HD
• CS film / CS mini / Horor film
  
• AXN HD
• HD+
• Ocko Expres HD

Sorry, for the slow response... and also I think I wasn't clear. I have to see a tune attempt in the log in order to be able to say whether the channel could have WSS signalling. So far I can say...

Maybe:

• CT1 HD
• Nova HD

No:

• Nova cinema HD

Can't check (not tuned):

• CT2 HD
• CT sport HD
• Prima HD
• Prima cool HD
• Prima ZOOM HD
• FANDA HD
• Barrandov TV HD
  
• CS film / CS mini / Horor film
• AXN HD
  
• HD+
• Ocko Expres HD

By the way, over the last few days I learned a bit more about VPS and WSS. I implemented pass-through support for VPS and WSS for TVE 3.5's TsWriter (digital channels) and TsMuxer (analog channels).

I am sorry for delay with answer, as the HTPC is on life operation, I did not have chance to do this sooner. I deleted all TV/radio channels and tunned them again, new log files are attached.

What exaclty means "a bit more"?[DOUBLEPOST=1426120141][/DOUBLEPOST]

Really!? This is very fast development So you dont need any more IFC in TV3.5 for channels with VPC and WSS signals, right?

Just that I read the standards and improved my understanding of how the information is passed.

Really!? This is very fast development

This speed is what is possible with TVE 3.5, because the code structure is much cleaner.

So you dont need any more IFC in TV3.5 for channels with VPC and WSS signals, right?

Wrong. TsWriter will include the information in timeshift and recording files now (it didn't do that before), but TsReader will still need to be modified to find and interpret the information before I.F.C. could be removed.

 

[mm1352000]

...new log files are attached.

Sorry, the new log files are no use to me. I can see that you scanned, but what I needed was for you to tune each channel (timeshift or record).

I see, so you can put information about the screen resolution into the stream via TsWriter, but somebody else has to add functionality to the TsReader (automatic TV zoom mode / or stretch), right?

Sorry, the new log files are no use to me. I can see that you scanned, but what I needed was for you to tune each channel (timeshift or record).

Aha, no problem, here is new one with timeshift.

Right.
...and also possibly some changes in MP on the C# side. I'm not sure.

Aha, no problem, here is new one with timeshift.

Thanks.

CT1 HD = maybe
CT2 HD = maybe
CT sport HD = maybe
Nova HD = maybe
Nova cinema HD = no
Prima HD = maybe
Prima cool HD = no
Prima ZOOM HD = no
FANDA HD = no
Barrandov TV HD = no
CS film / CS mini / Horor film = no
AXN HD = maybe
HD+ = no
Ocko Expres HD = no

If you want to check a channel for yourself then you can do it as follows:
1. Find the tuning entry in the TV service log, and note the date/time. For example:

[2015-03-12 08:30:24,713] [Log ] [19 ] [INFO ] - dvbc: TuneVBC:tv:upc Ocko Expres HD Freq:594000 ONID:1 TSID:124 SID:2401 PMT:0xF10 FTA:False LCN:10000 SymbolRate:6900 Modulation:Mod256Qam

2. Find the tuning process in the TsWriter log. For the above example, it is:

[2015-03-12 08:30:25,102] [9e820a0] [1398] - Recorder: TIMESHIFT got pmt - tableid: 0x2 section_length: 47 sid: 0x961

[2015-03-12 08:30:25,103] [9e820a0] [1398] - Recorder: TIMESHIFT pcr pid:0xf11
[2015-03-12 08:30:25,103] [9e820a0] [1398] - Recorder: TIMESHIFT SetPcrPid clear old PIDs
[2015-03-12 08:30:25,103] [9e820a0] [1398] - Recorder: TIMESHIFT add video stream pid: 0xf11 fake pid: 0x30 stream type: 0x1b logical type: 0x1b descriptor length: 3
[2015-03-12 08:30:25,103] [9e820a0] [1398] - Recorder: TIMESHIFT add audio stream pid: 0xf12 fake pid: 0x40 stream type: 0x3 logical type: 0x3 descriptor length: 9

Note "stream count: 2" and the stream types 0x1b (h.264 video) and 0x3 (MPEG 1 audio).

This channel does not have WSS encoded in a VBI sub-stream because it has no sub-stream with stream type 6.

Another example...

[2015-03-12 08:22:06,999] [9e820a0] [d04] - Recorder: TIMESHIFT PMT parsed - Pid 0x7a0 ServiceId 0x4b2 stream count: 5

This channel has 2 sub-streams with stream type 6 (private data). Note that such sub-streams are not guaranteed to carry WSS. Type "private data" is generic. For example, it could be AC3 (DD) audio, E-AC3 (DD+) audio, DVB subtitles, teletext... or something else. A teletext sub-stream could also carry the WSS.

Hope that helps your understanding.

Right.
...and also possibly some changes in MP on the C# side. I'm not sure.

And do you know, who can do this? What exaclty means "MP on the C# side"?

Hope that helps your understanding.

Thank you for very nice description

For channels where in "no" - does it mean this channels dont have WSS or VPC signals, right? Or they can use some other signals?

 

[mm1352000]

And do you know, who can do this?

Maybe @Owlsroost

What exaclty means "MP on the C# side"?

C# is a programming (code) language. C++ is another language.
TsReader (and TsWriter) is written with C++.
The control (main) part of MP (and TV Server) is written with C#.
So, I simply mean the control/main part of MP.

For channels where in "no" - does it mean this channels dont have WSS or VPC signals, right? Or they can use some other signals?

It means they don't have WSS or VPS signals carried in an MPEG 2 TS private data sub-stream. Perhaps that information can be encoded as part of the video stream. I don't know.
