Hi,

I am asking for advice how to solve following problem of one of my customers:

He has a full 1TB HD (perfectly working!) with recorded films out of this Panasonic
flat screen TV and wants to use it on a different TV from LG.

Looks like the recording from Panasonic is proprietory and I dont see files in
either Windows - nor with any the typical recovery software packages (R-Studio)

Has anyone delt with such "conversion" or can suggest a way ?

Thank you

+++

1. reverse engineer the format, I guess you guessed that one.

2. there is a guy in Australia that has been mentioned that was able to do similar work with DVR files. Its late and I am not able to search for it, but it is under one of my posts.

3. look at TV DVR hacking forums for anyone that has overcome it.

4. I would love to help and try and RE it if you can upload a disk image.. I thought TV in teenagers room was Panasonic, and it has those functions.. but its a Hitachi :(

sorry couldn't be more help.

Which model is that TV?

really strange, TV records to HDD and you cannot see it on a PC

@falther,

beside the proprietary format it will likely be locked because of Digital Rights Managements.
Other systems like STBs and other who use smart card based encryption save to HDD the stream "as is" and then it is agaim the scrambling subsystem that decode again the stream (in fact if you remove the smart card in the middle of viewing, it will stop playing).

Noth worth the effort, in any case. I would do do something different...

hi,
Does this help at all?
http://www.youtube.com/watch?v=kbFgVtsKQyg

also the files look like they can be mounted in Linux, maybe some compatible research here
http://www.avforums.com/threads/panasonic-viera-tv-usb-hdd-pvr-supported-drives-pc-access-to-recordings.1303759/page-5

though media looks not to be fully deciphered yet
Quote:
Working stages:
1-Fix de partition type
2-Mount the file system
3-Copy files into external system
4-See media files into Media Player

1-Fix de partition type:
System files are UFS2 used in FreeBSD. See them with Gparted (Ubuntu)

2-Mount the file system:
You can mount the file system from Ubuntu, using de command line (in graphic mode doesn't work):
sudo mount -t ufs -o ro,ufstype=ufs2 /dev/<partition> /media/<folder> (then you need to change file permissions.
In my case I activated a root account and I mounted:
mount -t ufs -o ro,ufstype=ufs2 /dev/sdb1 /media (see with GParted disk USB name, in my case sdb1)

3-Copy files in a external system:
Now you can work in graphic mode, You will find de mounted file system in /media, in a folder called "private", inside this folder are all files used by Panasonic. You can use Administrator files to change access permissions and copy them to everywhere you like.
For each recording will find four files with extensions: chp,aid,tts and vid.
Audio and video are in tts file.

4-See media files in a Media Player:
I STILL CAN'T PLAY MEDIA FILES. Only VCL Media Player recognize tts files, but don't find video. It would be some encryption, or I don't have correct codec

@ wow, thanks a lot - especially HaQue for that detailed input

Meanwhile customer got back the drive - but in a different USB enclosure.
The original is a Hitachi branded plastic box .... which I had to break to
get the hdd out of it.

... and guess what ... it doesnt recognise the data in this (different) USB
enclosure.

I think there is a kind of encryption related to the USB box - and after
conversation with customer its clear he is not prepared to invest in all
the necessary time for the conversion (or only for a try to do it).

I go with BlackST and forget that case ... customer should be able to see
his movies with the originally usb box on the Panasonic TV and just needs
to fight with his wife about who may use the TV set :roll:

Thanks again to all

Agree, some jobs best left alone to free up better paying ones and more important/fruitful ;)
