Abstract

The invention comprises a network TV adapter. The network TV adapter is used for receiving, filtering and demodulating a power line carrier signal through a power supply line, and then making signal conversion and decompression for it, and finally extracting the power supply provided for the TV as its power supply, the TV program signal provided for the signal receiving port of the TV and the TV control signal provided for the control signal receiving port of the TV. The invention can receives the network TV signals without a TV signal cable.

Description

Technical field [0001] The invention relates to a television device, in particular to a television device that only needs a power cord and no other signal lines are connected to a television access point. Background technique [0002] The existing television device has two external connection methods: the first one needs to be connected with a power cord, and at the same time, it needs to be connected with a TV signal access point through a signal line such as a coaxial cable or an Ethernet CAT-5 line. The second type needs to connect the power cord and configure a wireless communication interface (such as WLAN) to realize the information connection with the TV signal access point. [0003] For existing TV devices, if there is a certain distance between the TV device and TV signal access points such as set-top boxes, DVD / VCD and other players, such as not in the same room, it is not convenient to deploy dedicated signal lines such as coaxial It is not convenient for the user to s...
