Problems solved by technology

[0007] However, although the above implementation method quickly displays the channel list, the user does not need to wait for a long search, but if the ESG data in the current network changes, the user may still be able to operate the channel list displayed on the handheld device. The selected TV channel is played, or the next day's program preview displayed on the handheld device is wrong, and the user must still wait for the ESG data to be fully received

Embodiment Construction

[0025] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] The present invention provides a solution for how to quickly obtain ESG data under the DVB_H network. Its core idea is: most of the current DVB-H handheld devices are mobile phones based on 3G or 3.5G networks, and the 3G network can provide 384k / s download rate, and the 3.5G network can provide a download rate as high as 3.6M / s.

[0027] Under normal circumstances, the ESG data in the DVB-H network is only more than 200k bytes in total. Even if the subsequent ESG data will increase, due to the bandwidth limitation of the DVB-H network, it is impossible to add many TV channels, and the ESG data will only increase at most. Hundreds of Kbytes. Due to the high ...

Abstract

The disclosed E-service guide data transmission method comprises: step S102, setting a data server in core side of the network, and monitoring all used ports; step S104, when starting TV with hand-hold device, detecting current network signal and accordingly transmitting data.

Description

technical field [0001] The present invention relates to the field of digital video broadcasting-handheld (Digital Video Broadcasting-Handheld, hereinafter referred to as DVB-H for short) wireless communication field, and more specifically, relates to a data transmission method and system for an electronic service guide. Background technique [0002] With the popularization of the third generation mobile communication (Third generation, hereinafter referred to as 3G) technology in the world, more and more users start to watch mobile TV through the 3G network. Soon, operators discovered that more users watched TV on 3G networks, which not only took up valuable 3G bandwidth, but also brought high charges to users. [0003] DVB-H is a terrestrial digital TV broadcasting technology with low network construction cost, one-way broadcasting, and does not occupy the two-way bandwidth of the mobile communication network, allowing users to watch TV anytime, anywhere, at a very low pric...
