I found, that a new Panasonic's line up DMP BDT220/320/500 plays Sony's HDR-TD10 files perfectly in 1080-60i in my setup. They do not block third party TVs from displaying 1080-60i 3D content.
The SDXC card taken from HDR-TD10 has been treated as a Disk - instant 3D auto play.
Playback from BD-R/ BD-RE is not officially supported, but I burned a BD-RE disk using Play Memories utility and it did show up on the screen and played in 1080i 3D perfectly. The only difference from SDXC card - BDT 220 did not start autoplay of the disk, but showed the 3D content as a list of 3D files, grouped by date. You'll have to manually start the playback. It did not play in 3D files, placed in the root of the card or on the USB drive. 3D playback over the network did not happen as well. More investigations are to come, since the manual says - it supports AVCHD 3D playback for DVD-R/-RW media.
Only 40 min of the footage for a 8.5 GB disk, but it is just a matter of personal preferences.
I am considering the difference between the Sony S480 series bluray player and the Panasonic BDT220 series player, when used with TD10 3D files that are original 1080i60-3D.
Some TVs cannot display 1080i60-3D as a full resolution 3D signal which is a frame packed 1920x1080i60 x 2 eyes on the HDMI input. This type of signal is AVCHD 2.0.
3D TVs are sure to be compatible with 1080p24-3D and 720p60-3D, since that is the bluray 3D standard. Only some can do the AVCHD 2.0 signal that the TD10 produces, directly, which is not the bluray standard.
The question is - what does the bluray player do to the signal to make the AVCHD 2.0 from the TD10 compatible with a TV that cannot accept frame packed 1080i60-3D AVCHD 2.0 signal?
The choices are (1-3 below)
- Convert the signal to SBS 1080i60-2D, and let the TV display this as 3D. This is what the TD10 camcorder does with its own HDMI output for a TV that cannot accept AVCHD 2.0, when "auto" mode is selected in the HDMI output menu on the TD10. This reduces the horizontal resolution since the signal for each eye only gets half of the 1920 horizontal pixels.
- Convert the signal to 720p60-3D. This is what the Sony S480 series players is known to do.
- convert the signal to 1080p24-3D
I suspect that Sony is not "blocking" the other TVs, but instead the TV cannot directly
display a frame packed 1080i60-3D signal
Not sure if the Panasonic BDT220 series player is doing #1 or #3. My best guess is #1. Even though the user does not select SBS mode, 3DTVs can do this automatically.
Choice #3 would be great, since that's the highest resolution 3D signal (for non-AVCHD 2.0 TVs) , but it is more complicated to do smoothly, since it needs de-interlacing and down conversion of the frame rate from 60i to 24p. I suppose they could do it "not so smoothly," by simple 60i to 30p conversion, and then skipping 6 out of the 30 frames per second, to reduce the rate to 24p.
I wonder what the Panny BDT220 really is doing with this. Anyone take high speed photos of the frames?
