Your TV seems to access media over DLNA, a technology which allows you to stream media over the network. In order to have access to the videos, your computer needs to become a DLNA server, which the TV should detect automatically, once they are in the same network.
Step 1 – Install a DLNA server on your PC
You didn't specify your operating system, and there are many DLNA servers for Windows alone. That being said, I personally use TVMobili. It is freely available for almost all platforms and seems to support a large number of media formats and client devices.
Once installed, you need to tell it where your videos are. Add them to TVMobili's library.
Step 2 – Connect the TV to the DLNA Server
Once TVMobili has scanned your videos, you'll be able to access them over your TV. You will need to:
- Plug in the LAN cable and configure the TV so it can "see" the computer in the LAN
- Start up the DLNA Server (TVMobili) if you haven't done yet
- Connect to the DLNA Server. Consider reading the TV's manual for further details on how to do this.
- You should see an interface where you can browse your videos by name, date or folder. This interface can be configured within TVMobilis settings.
