DVB-T Closed Captions Appearing A Word at a time
« on: June 01, 2020, 06:02:33 pm »
I've recently moved over from Mediaportal to JRiver due to the quality of playback on movies, but I'm having a little issue with watching live TV with Closed Captions.

The captions will display a word at a time and clear the previous word when the new one arrives, but when I watch the same program on my Panasonic TV via DVB-T tuner each new word will appear but will remain on screen until both lines of text are complete and then clear ready for the next set of captions.

I have been able to record a TS file and it plays back the captions all ok, just on live TV.

I did try to record it in JTV format but couldn't figure out how to play it back outside of JRiver.

If it helps I am using a HDHomeRun Quatro Tuner.

I've attached a copy of the Filter Graph Info (TV graph) in case that helps.

Your graph info indicates that you were playing live TV in non-time-shifting mode.  Did you try time-shifting?  Would the result be different?

Apologies for the delay.

Attached is the graph info where JRiver is now Time shifting.

Your graph info file still is just for non-time-shifting.  With time-shifting on, the graph info file should look like the following (two graphs are involved, ."Filter Graph Info (Time-shifting writer graph)" and "Filter Graph Info (Time-shifting player graph)").

You do not need to send me another graph info file.  What I meant to say in my last post was that you should try playing in time-shifting and see if the situation gets better.  To turn on time-shifting, there are two ways:

  • Start viewing a TV channel live.  Then right-click in the video screen and choose TV Options > Start time-shifting.  Or
  • Without starting to play, click "TV Options", or Tools > Options > Television, and scroll down to Time-shifting section, and click "Start digital devices (including CableCARD devices) in time-shifting mode:", choose Yes.  This way each time you start viewing, it will be in time-shifting mode

Let me know how it goes.  Later on I may ask you to provide log files.  Click this link to read the wiki article on logging.

I followed the instructions about enabling the time-shifting, which I did and sadly it didn't make any difference.
I've tried to upload a clip on here to help demonstrate the issue but it failed to upload, so I've put it on YouTube https://youtu.be/g8iKatsj_A4

If you need me to send you some log files to help diagnose the issue, let me know.

Yes, please send logs.  With Logging turned on, run a TV channel in time-shifting mode, with subtitles on.  Then collect the logs.  email to me, yaobing at jriver dot com

Sorry, I have not yet.


I found the log file.  I will read it tomorrow morning.  It's good that you asked.  For some reason I accidentally deleted the email.

Please install the latest MC build, MC26.0.94, and then download these files and unzip, and copy JRTelevision.dll into the MC installation folder (64 bit), and copy MJTSFileReader.ax into the "TV" subfolder.

Let me know whether there is any improvement.

Thank you for those files, I have put them in the folders you've suggested and restarted the computer before watching live TV, which I'm sorry to say  hasn't resolved the Close Captions issue.

Please try this again.  This time there is only one file to update: JRTelevision.dll.  Copy it into the MC installation folder.

I've put the new file in as suggested and while it has helped with the Closed Captions completing over 2 lines before being replaced with new ones.

Here is a video of live TV (unscripted speech) https://youtu.be/6rjVNo2pkwI as you can see still has an issue.

Thanks for the feed back.

I think I understand the issue, but I don't yet have a solution right now.

Could you make a couple of recordings on a channel you are seeing the issue?  One recording should be in TS format, the other in JTV format.  Record them in MC for 30 seconds on a program you know closed captioning exists.  Please share the files with me using a file server.  Thanks.
