Subtitles on G 4305 DMP EtherDVB DVB - T channel

Hello world

Deakin Uni, we use EtherDVB (www.etherdvb.com) to take the public channels TNT and multicast them via the network.

To view these on our DMP of 4305G Cisco, we essentially have a playlist with the URL in the form udp://multicastipaddress:1234

This generally works well, and we have a minimum of audio/video synchronization problems.

These waterways using something like VLC, we can get the subtitles that go with the channel, but seem not to be able to have to show by the DPM (our firmware varies between 2.x and 5.1 on the DPM).

Our ultimate goal is to have access to the television channel shown on the DMP with subtitles for use in DMP facilities with significant background noise.

My (limited) research shows what may be something to do with the SRT files - IE how subtitles are broadcast with the audio and video streams in the transmission of DTT.

Does anyone have advice on how this can be done?

All assistance welcomed.

Kind regards

Kathy

Kathy,


Unfortuately, the DMP does not support flow incorporated for Closed Caption or subtitles

in a stream of multicast at the moment.  If the CC or subtitles were part of mulitcast video

flow then the DMP would be displayed to them.   A possible solution would be to

Cisco SA encoders or other encoders where you can add subtitles or CC to video

stream itself (using a text file or other formats) before transmitting on the DMP.

  • Creating a folder of music on g 4305 DMP

    Hi Tomas.

    We have just one of our g 4305 DMP improved since version 5.1 to version 5.2. I would like to test a mp3 music file.  In a previous post, you gave me the following instructions:

    "Using version 5.2 on a DMP - 4400G, I simply used a FTP client and copied the.

    music.MP3 remove DPM and placed in

    (self created) directory of the music.

    Once the file is successfully copied, I entered

    the following URL in the ACTIONS of the DISPLAY--> MEDIA URL

    Click START and the music plays successfully. »

    Can you please tell me what user id you used to create the music folder, I tried using the Web account and was awarded "of insufficient access privileges?

    I also tried to use:

    • my user id that I use to connect to the IAA DMM, because I put in place as an administrator

  • Can I have DVB - T and DVB - C channels in the same list?

    Toshiba TV have analog tuner, DVB - T and DVB - C.
    Can I use the same time channels DVB - T and DVB - C?

    My TV is connected to the cable operator with DTT and DVB - C signals and I would like to have channels on the same lists.

    Darek

    Hello

    I put t know what Smart TV you have but I n t think you can mix terrestrial (DVB - T) and digital cable (DVB - C) channels.

    My TV supports also DVB - T and DVB - C tuner and it is not possible to add DVB - T & DVB - C channels in the same list.
    However, I think in such cases its always recommended to read the user manual where these details and information are mentioned.

  • Music format for query DMP 4305 g

    Good afternoon

    Someone has already tried to copy music to a g 4305 DMP (internal storage or external USB) and do play music?

    If you have, can you please tell me what is the format of the music files should be and you add the files to the internal storage card or external USB?

    I am running with DMM version 5.1 and tried to add music (format .m4a) only, but can not get any music to play.

    If music should be in a play list, which should be the format?

    Also, if you have a playlist with say 50 pieces of music--the DMP play music randomly rather than the music of the parts in the order, if yes, can you tell me what I need to set up and how?

    I can play music if the playlist is created with a video, but I have a requirement to create the playlist with music only and not video.

    Thank you very much

    Linda

    Yes,

    I checked that it works on the DMP - 4305 G & DMP-4400 G running 5.2.

    For randomization, I just set up a playlist with all the mp3 files and

    Click the Randomize check box and the playlist mixture songs.

  • jpg made slow on g 4305

    I have a DMM 5.2.2.13 management 8 g 4305 DMP 5.2.1 running.

    The problem I have is some of the running jpg files in the playlist are rendering/loading slowly when they are displayed. More slowly load jpeg. Thus, for example, half superior image appears in a second or two the bottom half of the image is rendered for the full picture to display. jpg under about 260 k size images do not have this problem, but I have more than 260 k up to currently 800 k size JPEG.

    There are no tickers or other video, just the jpg file to fill the entire screen.

    Research on the question I made changes to the DPM who do not help. Changed the mode of access for read write memory, enabled caching and changing the syslog setting mode.  While I believe it was to help solve the problems with the 4400g I thought I'd try wouldn't them hurt.

    The playlist itself is 3 minutes in length with each slide showing 10 seconds, for a total of 18 slides. Total of 7.4Megs with a value of jpgs in the playlist.

    Jpg files are 1366 * 768 is the resolution of the screens and 72pixels/inch.

    If the jpg images files are to be smaller is there anywhere any documtation that indicates what size, if I can give to the people of design?

    I have seen from indicating that flash files must be less than 500 k, but nothing on jpeg files.

    Or is there another work around the rendering of images of slow?

    Thank you

    Mike

    Hi Michael,

    Are you by chance using progressive JPEG images? If this is the case, they are not officially supported on DMP 4305 such documented to:

    http://www.Cisco.com/en/us/docs/video/digital_media_systems/5_x/5_2/DMD/user/guide/media.html#wp1182846

    Try to convert the images to non-progressive JPEG and see if you see improvements.

    Another thing that you can use to improve the loading time of image is to use the preload feature. You can create a presentation of DMD with within a playlist, and then you have the option to set a time to preload for your image, as mentioned in the:

    http://www.Cisco.com/en/us/docs/video/digital_media_systems/5_x/5_2/DMD/user/guide/playlists.html#wp2150005

  • Qosmio F60 - L10 - how to set up the tv with integrated antenna tuner?

    Good evening
    I have a toshiba qosmio f60, I read your answer about tv tuner.
    My question is: how to set up the tv with integrated antenna tuner? Thank you

    The tuner is already configured!
    You must use Windows Media Center.
    Here, you have to choose the tuner and need to look for available DVB - T channels.

    Notes; Signals DVB - T depends on the country and region.
    In my area I needed an external antenna because the signal is too weak.

  • The DMP 5.0.2 to 5.2 reclassification issues

    I'm trying to migrate a DMM 5.0 box that runs on the old platform of hardware supported for a new DMM 5.2.1 box on hardware supported.

    Is it possible to upgrade ONLY the DMP and point them to a new DMM without upgrading the DMM?

    I'm having a time unable to get 4305 improved DMP from 5.0.2 to 5.2.1 due to the upgrade of the required core.

    I tried the upgrade of the first pit so that the DMP were still registered with the DMM 5.0 box. There no choice "is the kernel image" when creating the task of firmware tip dmp.

    I have advanced and updated the firmware to 5.2.1 on two 'test' DMP and keeps them on the DMM new performance 5.2.1 (changed DMM central IP mgmt and web account passwords). DMP are appearing, but fail to recover commands to reboot.

    I defined the core 5.1 as a medium on the new DMM and created the nucleus under tasks advance firmware upgrade.

    I start the upgrade of the core of the DMM 5.2.1.

    Under the "check status upgrade", it shows he's starting. The DMP eventually restarts, but even once, never recover.

    What I'm missing here?

    Any help is appreciated.

    Hooray!  Podcasts Connect has accepted my podcasts.  Unfortunately there are no subtitles.  In addition, my episodes on August 27 and 28 do not appear.  I have four episodes starting August 25.

    QUESTION 1: What do I do in order to get a subtitle to appear?

    Second QUESTION: Is there still a gap of two days in time?  If this is not the case, what I could do to ensure that my episodes are posted in a timely?

    It comes to my XML file.  http://www.nudge.online/protest/podcasts/hungerstriker_itunes.XML

    The episodes appear when you subscribe. It is quite normal that there are within 1 to 2 days before appear it episodes in the store.

    You have not; "melodies: subtitle ' tags that could fill in the"Description"column: iTunes and the store have used the content of the"itunes:summary"tag instead. The Description of the overall podcast in the store page comes from the 'itunes:summary' tag that once again you have. So it's not really important that the tag 'itunes:subtitle' is missing, unless you care to add it with some content you want.
