MPEG-4 Compatibility

As Nilex said that should not be the case. I’ve went through the process of getting guide data added myself. The channel appears and you can watch it without guide data until it gets added. This is likely something Tablo will need to investigate.

Thanks Jim and Nilex for the feedback. I just reached my 2 month anniversary as a new Tablo owner. WAPT 16.6 is the first subchannel to be added or modified since my Tablo went live. I wasn’t sure how the channel addition process worked, but figured that it should add the channel and show a “To Be Announced” or some similar message until guide data is properly mapped to the subchannel.

Given that @RD4 reports he receives MPEG-4 channel WVEN 43.7 and he has a network DVR, I figured that this subchannel should at least show up in my channel scan, even if the MPEG-4 video can’t be decoded.

I got a response from Tablo support and responded with the specific problem I am having, which is the channel scan not picking up WAPT 16.6 in the first place.

Granted Kyle from Tablo Support support access to my Tablo Quad just now. Hopefully, Kyle finds out why WAPT 16.6 is not showing in the channel scan…

We’ve received your session and have begun some testing to investigate. At the moment, we believe it’s possible (though not certain) this particular broadcast could be misconfigured - at least compared to the one @RD4 appears to be receiving without issue. We’d like to get a look at this channel as well, if possible, to gather more data.

I will leave my Quad in support access mode for as long as you need. Thanks for looking into it.

I am receiving

36395	23-10	Comet TV 	WUCW 	MINNEAPOLIS, MN 	720x480 (w)	DD2.0

When I scan with my SiliconDust HDHR Quatro, it finds the channel just fine and I can play and record.

When I scan with my Tablo Duo Lite (Tablo Device: 2.2.40, HTML Application:1.9.9 build 227 [202107161457]), channel 23.10 is not displayed as discovered. I will DM you with my contact information.

Supposedly channel 4.7 out of Milwaukee is GRIT-2. I’m already getting GRIT with channel 4-3. I just did a channel scan on my 11 year old Vizio and it did not find a 4-7. And it is not a channel in my Tablo. I’m not going to rescan Tablo currently because I don’t want to lose any channels.

I believe WVEN 43.7 has recently actually switched to 4, just noticed it disappeared after last scan (about 3 weeks ago). I scanned with a Zinwell ZAT-970A I dug out to use for signal meter (also has quality) it gets it but audio only.

RD4, thanks for the followup. I was curious as to why you could receive WVEN 43.7 MPEG-4 audio. With this information, it makes sense now.

Now that there are quite a few subchannels using MPEG-4, I hope that Tablo developers can modify the firmware to recognize and process that codec.

Are there that many channels or sub-channels broadcasting popular content in MPEG-4?

Apparently WKMG 6.6 RF 26 a new local Fl news channel is MPEG4.

Hooked up the Zinwell to check something last night, was flipping around noticed WKCF 18.2 RF 23 Tru Crime, was audio only. Looked at Tablo it had disappeared at same scan 43.7 did, another MPEG4 channel.

Is Tablo working on this?

You mean, “working on this”, as in the release of a totally new set of Tablo (new tuner hw) devices?

Software update new model or whatever. So simpler answer to question, yes.

With several years of ATSC 1.0 now expected is there any update on this from Tablo for development for the network connected devices?

I can add that the Tablo HDMI does not appear to support it either. Or at the minimum, when I did a scan, the Tablo service blocked the one channel that is MPEG 4 here in the Chicago area.

Is MP-4 support something that is possible to be incorporated with a firmware or software upgrade to the networked Tablo devices?
