Description

Display device combined with power line communication transmission

technical field

The utility model relates to a display device, in particular to a display device which obtains operating power and performs data transmission in combination with power line communication transmission.

Background technique

Present TV sets can also be connected with various video and sound machine systems through its video or sound input terminals except receiving TV programs. Due to the development of the Internet, televisions combined with the Internet have attracted even more attention. Taking the home network as an example, although the Internet is now mature, whether it is a cathode ray tube (CRT) TV or a liquid crystal display (LCD) TV, etc., unless the TV has a built-in Ethernet network (Ethernet), otherwise it cannot be directly connected to the home network. Therefore, it must be connected to the Internet through an external network conversion system. However, no matter which method is used to connect to the Internet, additional network cables must still be laid indoors, which is very inconvenient for users and will also affect the indoor landscape layout.

Therefore, a current one based on the HomePlug standard, through the power line network transmission (Power Line Communication, PLC) technology, came into being. Because the penetration rate of power wiring is much higher than that of Ethernet, telephone lines, and cable television. Therefore, many manufacturers have already invested funds in the research and development of devices supporting this power line network transmission technology and their peripheral products.

The so-called power line network transmission is a network transmission device that uses the mains power line system for network signal transmission. With the rapid development of network technology, the value of using power lines to transmit high-speed data has been paid more and more attention, because it has the characteristics of no need for rewiring, wide coverage, convenient connection and high transmission rate. As the transmission medium of broadband Internet access, the user only needs to plug the power line transmission device into the mains socket to directly access the Internet through the power line broadband.

Currently, the display device with built-in IPTV function obtains playback data via Ethernet or wireless network, please refer to Figure 1. If Ethernet is used, an RJ45 cable needs to be connected between the power line transmission device 130 and the IPTV 110. In the meantime, the IPTV 110 is connected to the network through the power line transmission device 130 to transmit data to each other, so that the IPTV 110 is not limited to whether there is a network transmission device in the Internet access location. However, the disadvantage of using this kind of power line transmission device at present is that the power line transmission device 130 needs to use the signal transceiver unit 133 and the signal conversion unit 132 to take out the network packet data from the AC power of the power line or transmit the network packet data to the network connection. Port 131 to IPTV 110. Similarly, the IPTV 110 also needs to receive network packet data through the network connection port 114 , and then transmit the received signal to a display 111 for playback through the signal converting unit 113 and the signal transceiving unit 112 . That is to say, the network packet data needs to be converted separately in the power line transmission device 130 and the IPTV 110 , which reduces the transmission efficiency. If the display device can provide the function of power line network transmission and Internet access, then only the power line of the display device can be used to access the Internet, which will be easier and more convenient to use.

Therefore, it is necessary to provide a display device combined with power line communication to solve the above problems.
