I have a Laptop and a 'TV with a USB enabled Set-Top-Box'.
Laptop: Intel i3, Linux 17.2.
The Set-Top-Box: Cable MPEG-4. Component video, Three-wire standard. Linux The Set-Top-Box has the USB facility [2Gb-7TB] on which programs can be recorded for later viewing.
What I am attempting to do is;
I want to copy other videos from other sources like Laptop, to the USB and view them on my TV.
What I tried is;
I disconnected the USB from the Set-top-box and mounted it on to the Laptop. However I could not open the contents, may be because of lack of an appropriate software that can read the files and also could not copy, paste files from-to the USB may be because of system permissions or File system differences. Since I am not well versed in computers, I do not understand much of what could be the problem.
What I found was; after a bit of my tinkering here and there was that the file system on the USB is Ext3. On the Gparted it shows that the software embedded on the USB i.e the Set-Top-Box is Linux. Here below is the information got from issuing the 'fdisk -l' command.
What I want to make possible is;Disk /dev/sdb: 7951 MB, 7951351808 bytes
1 heads, 62 sectors/track, 250483 cylinders, total 15529984 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0002e374
Device Boot Start End Blocks Id System
/dev/sdb1 2048 15529983 7763968 83 Linux
Can the USB somehow be accessed and the videos from my Laptop converted to appropriate formats [I read that Set-Top-Boxes use the .trp formats] and copied to the USB, so that they can be viewed on the TV.
I would very much appreciate any guidance towards achieving this.

Can you mount the /dev/sdb in linux? Or does that not work at all? Or empty?
You need to able to copy the files to the hdd without messing up the USB partition/file structure. But I guess it will be even harder to get your files in correct format so it plays on your set-top-box....so just get a chromecast or appletv.
Can you play the rec.pvr with for example VLC Media player? Or try open the rec.pvr with mediainfo and see if it can see any video details. If not I guess it will hard to get your files in similar file format.
Does the set-top-box manual mention anything about USB video-playback? Some boxes can play mpg, avi/divx/xvid files.
Most laptops have video output ports (composite, HDMI) these days. Connect that to your TV. Or get a standalone media player designed exactly for this.
Thanks for coming, Jagabo.
My argument here is; the STB anyway is a video player in itself, besides other things, and I just want to see if we can make it play, my videos.
Take for example the Canon printer. They came with cartridges that don't last longer. Then people modified it by fixing a Ink-Tank on it. Now the Canon company adopted the same thing. Now the newer Canon printer comes with an Ink-Tank fixed on it, on demand.
Just exploring the opportunities available, if there were any.
Thanks again Jagabo, for your input.
Given the proprietary nature of these files, it is very unlikely that you will find any software able to reproduce the trp container and encryption (if there is any) used by your STB. It would have to be custom written. Not only that, but the information required to create the custom software isn't public knowledge and readily available. It would have to be gained by analyzing the files themselves. Anyone who has the skills to do all that normally has better things to do with their time.
Thanks for coming, Usually_quiet.
And I would like to ask one more thing, just for knowledge sake;
Isn't it possible to entirely remove the OS on the STB and replace it with a free open source one, and still make the STB do what it does, plus do what I want it to do. Like I did it to my PC. Replaced Windows with Linux.
Thanks for your painstaking teachings, Usually_quiet.

Just get a media player, as others have recommended. I have seen some inexpensive players priced between $35- $40 sold online here that are still able to play a variety of video and audio formats and a fair number of container file formats.
An example: http://www.amazon.com/AGPTEK-Player-Remote-Optical-output/dp/B00NXODS4K/
There may be better devices available for a little more.

Can I watch the videos from my Laptop on the TV, by connecting thus? Would it require a converter in between? If so; how bout converting the HD video to NTSC, with the help of conversion software in my Laptop and then relaying it to the SDTV? Though the quality of the video would be degraded, but still I would prefer it because I can watch it on a bigger screen.
Thank you for being with me.
Unscrupulous sellers advertise cables like that knowing you're not going to demand your $5 back when you find it doesn't work. You need an HDMI to composite/audio converter box like this:
That device accepts a digital HDMI signal and converts it to analog composite video and stereo RCA audio signals. The device also requires power from a USB port. I believe there are some devices that siphon power from the HDMI signals
What is it a dvd recorder box, a cable tv box, a satellite box
Every one of these has encrypted files, you will not be able to play these on the pc or the tv
You will need to play them and capture them real time with another device
Thank you for being there, Jagabo.
What if I use a 'Video converter' to convert my video, to NTSC and then play it on the VLC-MP and then use the above discussed HDMI to RCA-AV cable to transmit that signal to the SDTV? Why would that not work?
And then there is another option I suppose. [I don't know whether I can mention this here, or have to start a new thread.] I have heard and read that, TVs, whether HD or SD, can be connected to the Laptops as an additional Monitor. And whatever is displayed on the Laptop monitor, is also displayed on the SDTV. I also have a slot on my Laptop, whose description in the manual is as below.
"Monitor port: A port used to connect a monitor, TV or projector supporting a 15 pin D-SUB interface."
The 15 pin D-SUB interface, refers to the projector I suppose, and not the TV. Or does the TV also, has to have it?
How about this?
How would that work? There is no mention of the requirement of a Converter here. Or is it understood?
Thank you for your painstaking explanation and the links, Jagabo.
You need an external VGA to composite converter to connect an analog TV to a PC's VGA port.
The best converters of this sort are more expensive.

Thank you for being there, Usually_quiet.
There is a software called "Plex". A media organiser that organizes audio and visual content from personal media libraries and streams it to mobile devices, smart TVs, and streaming boxes.
Now how about installing this application on my Laptop and then streaming the AV content to the STB, which would then transmit and display it on the SDTV.
Is that possible?
Are there appropriate cables available that can connect my Laptop HDMI or USB [whichever is needed for Plex streaming to materialize.] and the Coax? I searched the net for HDMI/USB to Coax cable, [Because that is what takes the input signal on my STB] I couldn't find any.
Thank you for the informative post, Usually_quiet.
Please post the make and model number of your TV.
This will allow the forum members to ascertain what is or is not possible.wake up this planet is dying!
Regarding the HDMI/composite cable: it's possible (though not likely) your laptop has the ability to convert to composite and output at the HDMI connector. You'll have to check your manual. And you will probably need to buy the cable from the manufacturer as there is no standard for this.
Beware of those cheap VGA to composite converters. They have tearing problems. And picture quality is pretty low (expected of composite video, of course).
https://forum.videohelp.com/threads/289827-Projector-Problem-Some-videos-smooth-motion-...=1#post1758608 (see second image)
I've never used any of the cheap HDMI to composite converters. They may suffer from the same problems.
Also be careful about mirror mode on the laptop (ie, where the external monitor/TV is mirroring what's on the laptop's screen). HDMI (or VGA) to composite converters are usually limited to certain resolutions and refresh rates. So they may not work in mirror mode.

There's an old saying
Putting the cart in front of the horse
In other words doing things backwards
Just buy a cheap media player, put your files on USB stick, or USB hard drive
Play it like a dvd etc.. Sony.. Roku etc.. There are many brands
Your recorder setup box is only going to play certain formats, and they might be proprietary
Not going to play your mkv and mp4 . Videos etc..
Couple of years back I bought a Homeworx PVR, it records over the air broadcast hi deff tv in mts format
It also play's back other formats, mpeg mp4 vob etc..
$49 then now on sale for $35
Even if you didn't use the record function, you get a good media player for a cheap price
HDMI and composite video outputs
And all the recorded files can be played and edited on my pc
Nothing is encrypted

There used to be some video graphics adapters that could be configured to output composite on one pin of their VGA connection, and would allow the computer to connected to an analog TV using a special cable obtained from the manufacturer. ...and some video graphics adapters had a dedicated TV-out port that would allow a computer to be connected to an analog TV using a special cable obtained from the manufacturer.
However, none of these features are likely to be available on a recent laptop because there isn't enough demand for them in a world where the use of analog TVs is dwindling.
Thank you Hamilton accie, for coming.
Model: FHR 15HA1, 53cms
Television System: CCIR B/G
Colour System: PAL, AV-NTSC
Channels: VHF E2-E12, UHF21-69, X-Z+2, S1-S41, CATV Hyperband Channels.
There is a page in the manual book in which a diagram is given under the heading, "Connecting other equipments". I am reproducing the page here below.
Thanks again Hamilton accie, for your compassion.
Thank you for being there Jagabo.
Plex, installed on the Laptop would transmit/stream AV signal to the STB, the STB should accept it as it would accept the regular incoming TV signal, without any problem? Or is there a catch there [The DLNA stream being different from a regular incoming TV signal, so the STB cannot accept it!]?
I thought when Plex streams AV to STB, the STB would accept the signal like it does with the regular incoming TV signal and transmit it to the TV.
If not; is there any other PC Application that would transmit the HD AV from the Laptop by converting it into a form that the STB would readily accept like it accepts the regular incoming TV signal?
Hey guys, this was a very informative discussion. Thank you all wizards, for imparting me this education. Love you all.
How to know, whether my laptop has the ability to convert to composite and output at the HDMI connector?
Thanks for, the concern and staying with me, Jagabo.
never mind. The STB is an IPTV box.
Though my TV does not have 15 pin D-SUB interface, can I use a '15 Pin VGA to 3 RCA Composite AV Cable Adapter', [like the one in the link given below] and connect my Laptop to the SDTV?
If this is possible, will the AV played on the Laptop be displayed on the TV, where both Audio and Video are available. I ask because, I read that the VGA transmits only video and one would need a separate audio cable to get the audio. But my TV does not have an exclusive audio input slot.
Is the 15 pin Monitor port available on my Laptop, actually a VGA slot or something else? If it is the VGA, then by connecting the above mentioned adaptor, will the audio also be available on the TV? I have given the image of the slots on the Laptop below.
Thanks for staying with me, Usually_quiet.

Plex is a DLNA server.
Face it, you're going to need a standalone media player that supports a connected USB drive, SMB (Windows network shares), or DLNA.
You can probably use a Vga breakout cable to supply a video signal to the TV
But you will need stereo audio cable with headphone jack on one end and rca plugs on the other end to get sound from notebook to tv, just like using a VCR
The tv had rca audio input jacks on it just for that reason
Monoprice's descript of their VGA to composite cable is the most honest I've seen:
Your video card MUST be able to support s-Video or Composite out through it's VGA port. This is known as a TV out function. If you don't know if your video card can do this, then call the card manufacturer and ask them "Does my video card support S-Video or Composite Video out through its VGA port?"IT IS NOT COMPATIBLE WITH NETBOOKS OR ANY CURRENT GRAPHIC CHIPSET.
jagabo and I already covered the problem of getting composite video from a laptop's VGA port.
