Problems solved by technology
However, this transmission method has many obvious disadvantages, such as the transmission of TV signals in the air, limited spectrum resources, low carrying bandwidth, and fewer channels for broadcasting TV programs.
As the signal propagates in the air, it will be affected by weather, vehicles, and other radio services, and the image quality is poor; with the construction of high-rise buildings in the city, the signal is more and more blocked, and people gradually move into buildings, so it is inconvenient to install antennas

The invention provides a television live broadcast method, device and system, a readable storage medium and a intelligent television. The television live broadcast method comprises the following steps: a first server provides description information of each television live broadcast channel for a intelligent television in communication connection through the Internet; the intelligent television receives the description information of each television live channel and displays the description information; obtaining a target television live channel selected by a user, and determining a DTMB demodulation parameter corresponding to the target television live channel; the second server transmits audio and video data of each television live channel to the intelligent television through a cable television network based on a DTMB protocol; and the intelligent television receives the audio and video data of each television live broadcast channel, and demodulates the audio and video data according to the DTMB demodulation parameter, so as to obtain the audio and video data of the target television live broadcast channel from the audio and video data and play the audio and video data. According to the invention, the existing network infrastructure and terminal equipment are fully utilized, a third-party CDN (Content Delivery Network) is prevented from providing services, and the television live broadcast operation cost is saved.
Description
technical field [0001] The present invention relates to the field of live TV technology, in particular to a live TV method, device, system, readable storage medium and smart TV. Background technique [0002] Live TV broadcasting is a business form in which live broadcast channels are transmitted from the source (or server) to the user's receiving terminal TV through a specific transmission channel. According to different transmission channels, there are currently three main forms of live TV services: [0003] The first form is terrestrial television broadcasting. [0004] The TV signal source is a transmission method in which TV stations send and receive TV signals on the ground through a TV transmission tower with a relatively high geographical location (such as the Oriental Pearl Tower, etc.) or using a ready-made mountain to build a station, and the TV signal uses atmospheric waves. The user terminal receives the signal through the antenna, and plays it through the TV c...
