[Network set-top box installation] How to install a network set-top box How to install a network high-definition set-top box
1. Local video resource input connection
For video resources stored in U disk or memory card, you can insert it into the USB interface of the set-top box as shown in the figure below. The USB ports are usually distributed on the left and back of the set-top box.
Tips: For the connection of the mobile hard disk, it is recommended to insert the two USB ports on the connecting line of the mobile hard disk into the USB ports on the set-top box to avoid the phenomenon of insufficient power supply.
2. Network cable signal input
For the cable network signal module next to the TV For families with routers or routers, it is strongly recommended to use a wired network to access the set-top box to provide video signal input. Obviously, the wired network signal is more stable and reliable than the wireless network signal transmission, which can make the TV picture clearer and smoother.
3. Signal output connection (HD cable connection)
For purchases within the past two years TVs have high-definition interfaces. Therefore, a high-definition cable can be used to connect an external device with a high-definition signal input interface, such as a TV, so that only one high-definition cable can output audio and video signals.
4. Signal output connection (AV cable connection)
For those without HD interface External devices such as old-fashioned TVs that only have AV terminal signal input can be connected by AV cables. However, since the AV cable has 3 connectors, it must be noted that the colors of the three cable ends should be in one-to-one correspondence, and are respectively connected to the corresponding interface of the set-top box and the rear of the TV.
Tips: Red, white, and yellow are divided into three color tables to represent “Right Channel”, “Left Channel”, and “Video”.
5. Signal output connection (color difference component line connection)
For the most drawing quality TVs without high-definition interfaces. If there is a color difference component line interface, you can connect the set-top box and the TV through the color difference component line. The color difference component line has 5 terminals, of which the green, blue and red terminals connect the Y, PB, PR output terminals on the set-top box with the corresponding three terminals on the TV to transmit video signals, and the other two red and white terminals. In the same way as the AV connection, the audio signal is transmitted.
6. Signal output connection (coaxial or optical output)
Some families do If the home theater has special decoding equipment such as power amplifier, you can use coaxial or optical fiber to connect the two, as shown in the figure below, the red box is the coaxial interface, and the yellow box is the optical fiber interface.
