Connecting the television with satellite/ cable/ antenna:
Firstly, connect the in port of the satellite receiver or cable box with the coaxial cable coming out from the wall. Then, take the second coaxial cable and connect one end with the out port of the satellite receiver or cable box and the other end into the ‘in’ port of the television. In case you are connecting an antenna, just insert the other end of the antenna cable into the 'antenna in' or 'cable in' port of the television.
Connecting the video switcher with the television:
The next step is to connect the video switcher with the television. There will be various types of video switchers available, with each having a different number of ports. However, irrespective of this fact, these ports will be grouped as either out ports or as in ports. Keep in mind that the in ports are meant for connecting the external devices while the out ports are meant to connect to the television. For this reason, there is usually a single set of out ports on a video switcher.
For ease of installation, the cables and ports on the video switchers are coloured coded in order to help people insert the right cables more easily. The yellow colour of the cable is meant for the video while the white and red ones are meant for stereo and audio streaming.
So, insert the yellow coloured video cable into the same coloured out port on the video switcher, and connect the red-white RCA stereo audio cables to the same coloured out ports on the video switcher.
Now, take the other end of each of the cables and insert them into the corresponding coloured A/V in ports on your television.
Connecting the video switcher and external devices:
Now, locate the out ports on the external device and insert the audio and video cables into these ports. This can be a DVD player, a VCR, a gaming console, or a digital camcorder. Then, insert the other ends of these cables into the video switcher. So, first locate the in ports on the video switcher, then insert these cables into the same coloured ports.
Verifying the connection:
Now that you have connected the devices, verify the connection by turning the tv on and selecting the A/V button. If it is not working fine, then you might have inserted the wrong cable into some port.
Connecting more devices:
Repeat steps 2, 3 and 4 if you want to connect more devices.
