Recording with USB stick on a Polaroid TV

[techmot]

I have a Polaroid TV (model P24RD0039E) and I'm trying to find a way of getting the recordings from the USB pendrive that I have used to record onto from the TV. Looking at the manual it just says it formats in the Fat32 system. I have played back the recording from the TV and the recordings are there, but when I plug the pendrive into my laptop the file is unreadable, the extension ends in a .ts. Anyone know what I need to do to get the files off and onto my laptop?. On my August TV recorder using the same pendrive I can just connect the pendrive to my laptop after recording a TV programme from the machine and it can read and recognise the file, but on the Polaroid TV it can't. I'm guessing I need to reformat the pendrive?.

Do you have VLC or MPC-HC installed on your computer, Attach a file from those recordings so members will take a look at, Or at least post Mediainfo information from the file, Don't expect an answer with no details given.

Are you sure that the recording is not encrypted? Many TVs nowdays do not allow their recording to be exported.

I'm not sure, it was recorded from terrestrial TV (freeview) so unlikely to be encrypted, and plus I have recorded from the same channel through my August TV recorder using the same UBS pendrive and havent this issue. It could be the TV system needs to USB drive to be reformated, but there's no mention of doing this on the TVs manual.
I opened up MediaInfo clicked the file but all it says is the channel it was recorded from, the date and time and ending in a .ts. That's it. On the TV it records in MPEG, that's all I know.

Not encrypted in broadcast, but by the TV while recording. My Samsung TV does that. I need a special hack to export the recorded files (SamyGO)

Oh right I didn't know that. Why would a TV need to this for?, seems abit stupid. It could be just because the pendrive hasn't been formatted, but it seems abit of a pain to keep doing this everytime I want to copy the files over to my laptop, and as I said, my August TV recorder doesn't do this. Strange that Mediainfo doesn't give any details about the file other than the .ts and timecode data.

The TV is a Polaroid, I couldn't imagine it having some encryption built in like a Samsung. Where do you get a hack for it?

[lollo]

Why would a TV need to this for?

Because "rights" on the programs and piracy . Unfortunately is very common today.

Here in Italy, most of the legal CAMs CI+ for subscribed pay tv channels (DVB-S and DVB-T) do not allow recording. All certified DVB-S set top box receivers encrypt their recordings as the Samsung TVs (but no hack exists).

I do not know if this is the case for your television. For Samsung TVs I use https://forum.samygo.tv/

Why would a TV need to this for?

Because they like not being sued for facilitating copyright infringement?

What about the old days with VHS? they weren't bothered then. Is there anyway of retrieving the files and playing them on laptop?. The recordings were recorded as they appear on the pendrive when I play the files through the TV, but they are unreadable/unplayable for some when I plug into a Windows PC. I just assumed that the USB stick hasnt been formatted properly. I don't understand why Mediainfo doesn't say anything about the file, just the timecode and the .ts. Someone mentioned a hack, how do you do this?. I plugged it into another TV but it says unsupported file.

[dellsam34]

How about posting a file from the USB drive as I suggested in post #2? Any file under 500MB should be attached here without problem, Without knowing what files you have no one is able to help you.

File attached, hope this is of any help
Maybe the files need finalising on the TV, but looking at the manual it doesn't mention this needs to be done, unless I've missed something.

If not corrupt for any reason, the file is encrypted and can be played only on the TV where has been recorded. I ignore if a hack exist for your specific TV:

What about the old days with VHS? they weren't bothered then.

Because the vhs recorded videos were lower quality compared to original.

Today you do not "record", with your TV or other devices just make a copy bit-by-bit identical to what is broadcasted, in full HD or 4K.

So there's no way of getting the files to play then?. Seems abit stupid if you can only play the files onto the TV it was record on.

If they are encrypted and there is no hack, no, they can only be played on the original device. Bad case. Worst situation is when you are not even able to record!

The file size of the recorded programmes seem pretty small for them to be bit for bit copies, though I can't see any loss, though the quality of the broadcast seems quite compressed with noticeable artefacts, and this is only a small TV. I'm guessing the broadcast is using a low bitrate.

There must be a hack somewhere, there's always a way around something. Would it be possible to connect the TV upto to a laptop and capture the recording onto something like Virtualdub?.

[lollo]

Do you mean an "analog capture" via VirtualDub and a capture card? In principle yes, but I doubt your TV has analog (or other) output to feed a capture card...

edit: in alternative, if you are expert in the domain (I am not) you could try a "brute force" attack to extract the key and do an offline decryption. We used to do that at the time of beginning of dvb-s pay TV, but the keys were easily and legally extracted from the smart card. Here the key is unknown, and only a brute force could retrieve it

I don't understand why the manufacturer of the TV has gone to so much trouble in encrypting recorded files. The key must be known somewhere.

It has been this way for at least 15 years. Your exact same scenario has been known to the world (and here at VideoHelp) for a VERY LONG TIME and what you are describing has been an INDUSTRY STANDARD for at least 15 years. All of your reposting WILL NOT CHANGE THIS.
I predict the usual....you will continue to refuse to accept this.....give up....then come back here a little later and LIE about finding/breaking the encryption, providing ZERO details of your secret miracle cure.
Any Bets?

It's already been explained to you. The TV manufacturer doesn't want to be sued by copyright holders for enabling copyright infringement. Or maybe they already have been sued, lost, and agreed to encrypt the recordings.

Yes, it's stupid and doesn't stop copyright infringement. But producers continue to pursue lawsuits like that. Manufacturers find it easier to acquiesce than fight.

Some people find that converter boxes like the one below that record from Freeview channels to a USB stick are fine for their purposes:
https://www.amazon.co.uk/Freeview-Set-Top-Box-Televisions/dp/B00BPAZGCG/ - This one records to NTFS-formatted USB drives which means file sizes over 4GB are allowed. Never mind. I spotted your other thread. You already have one of these.

There are TV tuners for a PC that will allow a computer running NextPVR or other PVR software to act as a DVR for Freeview. It is not as easy as using a TV or set-top box to record but people do find this method works well for them.

I have one of these:

https://www.hauppauge.co.uk/site/products/data_dualhd.html

and it works well for recording free-to-air TV on my PC in TS or MPEG format, which I edit later for display on my home network. Only hassle is getting a TV aerial cable to the USB stick (the supplied mini aerial is not very sensitive, I found).

I have a different Silicondust model but all the HDHomerun tuners have an Ethernet connection which can be used to connect them to a router or directly to a PC. When they are connected to a router, PCs on the network are able to connect to the tuners via a wired network connection. (I haven't tried using a wireless network connection from my router to access my Silicondust HDHomerun tuner but it may work if the wireless signal is strong enough and there is enough bandwidth.) The tuner must still be connected to an aerial cable but if it is connected to a wired network, the tuner can located be in a different room than the PC using it.

In case you're not aware: cases like this scare the shit of of manufacturers:

https://www.eff.org/deeplinks/2021/06/if-not-overturned-bad-copyright-decision-will-le...-lose-internet

In this case, the same court found that Cox (an internet service provider) was on the hook for the copyright infringement of its customers and upheld the jury verdict of $1 billion in damages—by far the largest amount ever awarded in a copyright case.

Only in America...

[dellsam34]

This has been going on for years, We keep voting like a sheep for the most two corrupted political parties in history enabling their wealthy donors to infiltrate our gov system and shape the laws for their benefit, Americans need a wake up call. Although I'm against piracy and copy right infringement, Such laws can hurt our freedom of choice and the quality of services we pay for.

[usually_quiet]

It could be worse than a TV's recordings being watchable only on the individual TV that made them. What if it wasn't possible for the TV to record at all? I can't remember ever seeing any US-model TVs able to record the output from their digital tuners on a USB stick.
