with the development of network technology, the coverage of DTMB signals and the development of users, the deep fusion of various communication technologies and the Internet is greatly promoted, the information acquisition requirements of people are increased day by day, and business innovation and service mode innovation are required to be continuously carried out, so that the upgrading of the whole industry is realized by the dynamic growth of new technology and new application.
The DTMB sends data mainly in a broadcast form and only transmits data in one direction, and under a real use scene, if private protocol data of multimedia information is multiplexed with local DTMB signaling equipment, only lM to 2M of transmission bandwidth is provided generally. The 4G network divides a given channel into a plurality of orthogonal sub-channels in a frequency domain, one sub-carrier is used for modulation on each sub-channel, all sub-carriers are transmitted in parallel, a terminal can select to download required resources only, resource waste is avoided, and the transmission rate of 4G can be as high as 20Mbps, even 100 Mbps.
In the prior art, multimedia information is transmitted only by using DTMB, if the multimedia information contains more pictures or videos, the transmission rate of the DTMB is limited, so that the transmission time is long, the requirement of a user for uploading the multimedia information in real time is difficult to meet, the multimedia information cannot be updated in time, and the problem that all channels are occupied by multimedia information transmission is solved.

In addition, the effective distance is long, the bandwidth can be adjusted to 5.5Mbps, 2Mbps and 1Mbps under the condition of weak signals or interference, the automatic adjustment of the bandwidth effectively ensures the stability and the reliability of the network. In an open area, the communication distance can reach 305 meters, and in a closed area, the communication distance is 76 meters to 122 meters, so that the integration with the existing wired Ethernet is convenient, and the networking cost is lower. And the threshold for manufacturers to enter the field is low. Manufacturers only need to set a 'hot spot' in a place with dense personnel, such as an airport, a station, a coffee shop, a library, and the like, and access the internet to the place through a high-speed line, because the radio wave emitted by the 'hot spot' can reach a place with a radius of tens of meters to 100 meters from an access point, a user can access the internet at a high speed only by taking a notebook computer or a PDA supporting a wireless LAN into the area. That is, the manufacturer does not need to spend the capital to perform the network wiring access, thereby saving a great deal of cost, which is the effect that the DTMB can not achieve when performing the live television and multimedia information transmission.

s12, the high-frequency tuner carries out frequency conversion processing on the received DTMB signal to obtain an intermediate frequency signal, and the intermediate frequency signal is amplified and filtered;
and S13, transmitting the signal output by the step S12 to a channel demodulation module for demodulation, and transmitting the generated live television information stream to a signal conversion device.
8. The method for releasing live television and multimedia information as claimed in claim 6, wherein the step S20 specifically includes the following steps:
s21, the main control module converts the live television information stream transmitted from the DTMB receiving device into a live television transmission stream, controls the storage module to receive and store the live television transmission stream and transmits a multimedia information stream from the cloud server, and controls the communication module to read and transmit the multimedia information stream;
s22, the storage module receives and stores the live television transmission stream and the multimedia information stream transmitted from the cloud server;
and S23, the communication module reads the address in each information flow data packet and transmits the address to the corresponding information distribution terminal.
9. The method for releasing live television and multimedia information as claimed in claim 6, wherein the step S30 specifically includes the following steps:
s31, the main control module controls the relative work of the storage module, the video processing module, the audio processing module and the positioning module;
s32, the storage module stores the live TV transmission stream and the multimedia information stream received from the signal conversion device;
s33, the video processing module and the audio processing module carry out video and audio processing on the data in the step S32;
and S34, the positioning module collects the position information of the information release terminal, stores the result in the storage module, sends the position information to the signal conversion equipment through the communication module, and transmits the position information to the cloud server through the signal conversion equipment, so that the cloud server can manage the information release terminal.
