Abstract

The embodiment of the invention discloses power line-based digital television signal accessing method. The method comprises the following steps of: receiving a power supply signal and a digital television signal by a power supply module in a digital television; separating the digital television signal; and sending the separated digital television signal to a central processing unit in the digital television for processing. The embodiment of the invention also discloses the digital television. The digital television comprises the power supply module and the central processing unit, wherein the power supply module is used for receiving the power supply signal and the digital television signal, and separating and sending the digital television signal to a modulation/demodulation module; and the central processing unit is used for processing the digital television signal separated by the power supply module. By using the method and the digital television, a user can watch related program contents of the digital television through a power line.

Description

technical field [0001] The invention relates to the technical field of power line communication, in particular to a method for accessing digital television signals based on power lines and a digital television. Background technique [0002] With the rapid development of broadband network technology, it has begun to play a huge role in people's work and life. Online distance education, online publishing, printing, online communication, and online TV have shrunk the world and shortened time and distance. [0003] At present, a new broadband access technology, that is, power line access, is emerging. Power line access technology, referred to as PLC, refers to a communication method that uses power lines to transmit high-frequency data and voice signals. The modem connected to the Internet through the power line is referred to as "power modem". One end of it is plugged into the user's computer, and the other end is plugged into any power socket in the home to achieve a transmis...
