Embodiment 1

[0050] Example 1: as figure 1 As shown in the schematic diagram of the overall system, the system includes: DTMB receiving equipment, signal conversion equipment, information release terminal, cloud server; wherein the output end of the DTMB receiving equipment is connected to the signal conversion equipment; the output end of the signal conversion equipment is connected to the information release terminal ; The cloud server is connected to the signal conversion device;

[0051] Preferably, the signal conversion device communicates with the information distribution terminal in a WIFI manner.

[0052]Information release terminals include traditional display terminals, which can be commercial display devices such as advertising machines. Specifically, the display screen of the information distribution terminal displays live video content and several multimedia information in different areas. The display screen of the information release terminal supports multi-screen split pro...

Embodiment 2

[0073] Example 2: as figure 2 The flow chart of the system is shown, and its steps include:

[0074] S10: the DTMB receiving device receives the DTMB signal from the TV tower, and the received DTMB signal is demodulated by the channel demodulation module and then transmitted to the signal conversion device;

[0075] S20: the signal conversion device receives, stores and processes the live TV information sent by the DTMB receiving device and the multimedia information sent by the cloud server, and finally transmits to the information distribution terminal;

[0076] S30: The information distributing terminal receives the live TV information and multimedia information transmitted from the signal converting device, performs data processing and stores it, and then plays it.

[0077] This embodiment supports tabulation and visualization of information release terminal information, and each attribute of the information release terminal can display specific information, such as trac...

Embodiment 3

[0078] Example 3: as image 3 Shown, carry out embodiment 3 on the basis of embodiment 2 execution process;

[0079] Specifically, the above step S10 specifically includes the following steps:

[0080] S11: The DTMB receiving device receives the DTMB signal from the TV tower through the antenna;

[0081] S12: the high-frequency tuner obtains an intermediate frequency signal after performing frequency conversion processing on the received DTMB signal, and performs amplification and filtering processing on this intermediate frequency signal;

[0082] S13: The signal output in step S12 is transmitted to the channel demodulation module for demodulation, and the generated live TV information stream is transmitted to the signal conversion device.

[0083] Specifically, the demodulation in step S13 is mainly to perform deinterleaving, channel demodulation, descrambling and other work on the signal to generate a video or audio transmission stream and transmit it to the signal conver...

Abstract

The invention discloses a live television and multimedia information publishing system and method, and the system comprises DTMB receiving equipment, signal conversion equipment, an information publishing terminal, and a cloud server. The output end of the DTMB receiving equipment is connected with the signal conversion equipment; the output end of the signal conversion equipment is connected withthe information publishing terminal; the cloud server is connected with the signal conversion equipment; the signal conversion device communicates with the information publishing terminal in a WIFI mode. Meanwhile, the invention further discloses a live television and a multimedia information publishing method. According to the invention, WIFI communication is set between the signal conversion equipment and the information publishing terminal, and fourth-generation communication or higher-level wireless transmission standard communication is set between the cloud server and the signal conversion equipment. The technical problems of low live television information and multimedia information transmission rate, complex wiring process and high cost in the prior art are solved, and the beneficial effects of high transmission rate, easy wiring operation and low cost are achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to a live TV and multimedia information distribution system and method. Background technique [0002] DTMB (Digital Television Terrestrial Multimedia broadcasting), digital TV terrestrial broadcasting; [0003] With the development of network technology, the coverage of DTMB signals and the development of users have greatly promoted the deep integration of various communication technologies and the Internet, and people's demand for information is also increasing, which requires continuous business innovation and service model innovation , to drive growth with new technologies and new applications, and realize the upgrading of the entire industry. [0004] DTMB mainly transmits data in the form of broadcast, and only one-way transmission. In real usage scenarios, if the private protocol data of multimedia information is multiplexed and transmitted with the local DTMB signal sending equipme...
