Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] In the existing advertising data transmission, only DTMB is used for transmission. If the advertising data has a lot of content and occupies a large space, the transmission will take a long time, which is difficult to meet the needs of users to upload advertising data in real time, resulting in that the advertising data cannot be updated in time. , and the transmission of advertising data will occupy all channels.

[0027] Such as figure 1 As shown, in order to s...

Abstract

The present invention relates to the technical field of advertising data updating, in particular to an advertising data updating system and method based on DTMB and 4G transmission technology. Data download server; Client, including the DTMB signal receiving module remotely connected with the update message push server, and the 4G download module remotely connected with the update data download server. The present invention solves the problem that only DTMB is used for transmission in the existing advertisement data transmission. If the advertisement data has many contents and takes up a large space, the transmission will take a long time, and it is difficult to meet the user's demand for uploading advertisement data in real time, resulting in advertisement The data cannot be updated in time, and the transmission of advertising data will occupy all channels.

Description

technical field [0001] The invention relates to the technical field of advertisement data update, in particular to an advertisement data update system and method based on DTMB and 4G transmission technologies. Background technique [0002] DTMB (Digital Television Terrestrial Multimedia Broadcasting, digital TV terrestrial broadcasting) is suitable for mobile reception and can be used for vehicle video, 4G technology, fourth-generation mobile communication technology and IP-based core network. interconnected. [0003] DTMB mainly sends data in the form of broadcast, and only transmits in one direction. In real usage scenarios, it is necessary to multiplex and transmit the private protocol data of advertising data with the local DTMB signal sending equipment. Generally, only 1M to 2M transmission bandwidth. The 4G network divides a given channel into many orthogonal sub-channels in the frequency domain, uses a sub-carrier for modulation on each sub-channel, and transmits ea...
