1080/60P output via HDMI on HDTV

[jbartosh]

I own one of the Panasonic 1080/60P camcorders and in the manual it cautions against being sure your HDTV can playback 1080/60p through an HDMI port. This isn't a common spec that mfg's choose to advertise... Google search returns only a Sony Bravia that promotes 1080/60p capability (http://store.sony.com/p/KDL-40S5100/en/p/KDL40S5100). My thinking would be that any 1080p progressive scan capable TV with a minimum of 60hz refresh should be capable??? Any ideas here? I would think HDMI should be able to support 1080/60p (though finding out which standard a TV uses also is a deeply hidden fact) as HDMI 1.4 seems to promote something like 4k support. Just wondering if anybody can point to some hard facts to determine what hardware is actually needed to accomplish 1080/60p. Thanks!

all ntsc tv's refresh at 60hz or higher. hdtv standard of 1080i30 is 60 fields/second. 1080p60 is not part of the blu-ray spec and finding a tv that plays it is uncommon as you found. don't count on any tv doing so unless it's listed in it's specs.

hdmi specs have nothing to do with what a tv will play.

I'm just thinking that the frames per second shouldn't matter. The TV is not doing the encoding/decoding I shouldn't think - the camcorder when it's hooked up for playback or a connected PC is handling the video codec strictly is it not? I would think that any native 1080p TV wouldn't care if it's getting 30 or 60 frames and that it's not going to drop frames given 60p input but give full 1080/60p reproduction so long as the source is providing it and the input method (hdmi) is transferring all of the data. Could anybody confirm or deny that thought and fill in the details here? To clarify I'm not looking to get just any signal back, but full, zero loss 1080/60p back on my *future* TV.

just like a 1080i30 tv will refuse to play 1080p30 over hdmi the same is true for p60.

I could perhaps see a 1080i tv having trouble with any 1080p signal. But what about a 1080p TV handling the difference between 30p & 60p. The only difference is the framerate and perhaps bitrate (which should be the responsibility of the source (camera, computer, game console etc., cable used and the interface - correct?)). At least there is no change between interlaced or progressive scan going on in what I'm querying.

I own one of the Panasonic 1080/60P camcorders and in the manual it cautions against being sure your HDTV can playback 1080/60p through an HDMI port.

Where? I searched for every instance of 1080/60p in the TM900 manual and found no such warning.

Anyway, look for the HD ready 1080p in Europe if you want to make sure your TV supports any and every 1080p input source. Here in North America things are more of a hellish wasteland with regards to standardizing. Maybe the Full HD logo would be enough.

The opposite is true. Try to find a 1080p TV anywhere in the world that doesn't take in a 1080p60 signal over HDMI (even in Europe).

"HD ready 1080p" is a non existent techseller bla bla, really.
Either its "HD ready" or its "Full HD" alias 1080p... (common is 1080i for most DVB devices so far).

[Brad]

What are you talking about? Because I'm talking about standardized logos.

That is wrong. Many sets will not accept 1080p60 as input even though they display 1080i30 input as 1080p60. Their video processing hardware may not be able to keep up with 1080p60. That said, in my experience, most newer 1080p HDTVs will accept 1080p60 input, most older HDTVs won't. Even our two year old, ~$250, 1080p, 22" Vizio LCD accepts 1080p HDMI input.

[Brad]

Can you give an example? I've never heard of this. I bought my TV in 2007 and all the TVs that I looked at then had no trouble with 1080p60 inputs.

Well, you really need to update your current knowledge then.

I dont feel to repeat what I already wrote, so please read it again, carefully.

Thanks for wasting everyone's time then.

The case is different in the EU where there are terms defined by law. In the USA the terms are defined by marketers and mean whatever the advertiser wants them to mean.

Yeah, its a weird case.
