Re: TV Station Launches Multiple 4K Broadcasts OTA on ATSC 1.0

It's both. Video codec will have a major impact on image quality. Better video compression codecs allow the same or better quality while using less bandwidth. It's possible to still lowball the bitrate too much, but AVC is roughly twice as efficient as MPEG2, and HEVC is roughly twice as efficient ...

Re: TV Station Launches Multiple 4K Broadcasts OTA on ATSC 1.0

I wish more channels would do this. We have three sub-channels that broadcast in AVC in Chicago, and you can see the quality difference. At the same time, it saves bandwidth. Quality is based on the bit rate and resolution, not the encoding format (although there are good and bad encoders too). All...

Re: Recording metadata - TPeterson

Shows up" where? Does the app look in a particular folder for recordings? What syntax did you use, if not a dedicated folder? Also, what utility did you use? It shows up in Recordings in the HDHR app on all platforms. I placed the mpg file in the default recording folder which was C:\Users\Pub...

Re: Recording metadata - TPeterson

Unless this is new behaviour, I've use a utility to add the metadata from NextPVR to an NextPVR created ts file and the file with metadata shows up so check the logic and the mpg file you are using.

Re: Encryption

with the signal of the ATSC 3.0 channel being encrypted the broadcasters are in violation of both the emergency alert system and educational/informational rules established by the FCC. Old analog TV's and capture cards don't receive ATSC 1.0 so that rule would apply to compatible TV receivers not a...

Re: No Sound On Roku - tsberry901

The Panasonic ATSC receiver logic will have the antenna, video and audio AC-3 decoder. The Roku is just passing audio and video through HDMI, totally different circuitry.

Re: No Sound On Roku - tsberry901

Low end Roku sticks don't have AC-3 decoding so you need to pass through audio to an amp not a TV to get sound.

Re: Use HDHomeRun when there's no Internet??

The tuner is available, the API that some applications use may not be. With ATSC 3.0 there are more restrictions though, another reason DRM should not be considered in the public interest.

Re: Samsung Tizen AC-4

Ok thanks, too bad, in a remuxed mp4 container recordings play nicely on the Samsung. I will have to see if I can script the extraction and remux process.

Samsung Tizen AC-4

I am developing a Tizen client for NextPVR which plays HDHR sourced files in Tizen but I get no audio on AC-4 tracks, same issue with Silicondust sourced mpg files. When I extract the tracks and remux to mp4 then it works. Does anyone know if that is expected behaviour or just the monitor I am testi...

Re: List of Supported devices

Both Emby web and Emby Theater do use the unreleased ffmpeg AC-4 patch. If you are getting 7.1 I think there is something wrong in their transcoding options.

Re: List of Supported devices

ms12 is the Dolby transcode library. You pass AC4 audio to the audio output device as if it were AC4 passthrough and this library converts it to AC3 for AC3 passthrough (or PCM for PCM output). So will this go to your transcoding server or will it always go through passthrough, independently from t...

Re: List of Supported devices

I just tried a player Rocktek G2 and it seems to support AC-4 via ExoPlayer. My device is against 103B4218 and 10529531 but I played from a DVR test and would be interested in know how AC-4 is played back on this device.

GuideName differences

Shouldn't the GuideName in legacy lineup match the lineup.json? They are different here.

"GuideName": "CBOT",
vs
"GuideName": "CBOT-DT",

Re: XMLTV guide data

They did give direction in this thread viewtopic.php?t=77340 although I don't know if they will have an account based solution by early 2024.
