Problems solved by technology

But the obvious disadvantage is that users need to wait for a long time to obtain the required information, waiting for the arrival of specific data (required data) cycle
To reduce the waiting time of users, it is usually achieved by shortening the data period in the data carousel, but this method greatly increases the consumption of network bandwidth, increases costs, and limits subsequent development; or reduces the amount of data sent in turn, Reduce the amount of information that can be provided, but this method is difficult to meet the needs of users

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] In the embodiment of the present invention, the index information of the information data is provided before the information data is transmitted, and the user selects the index information of the information data concerned according to the index information of these information data, and stores the selected index information in the digital terminal device . The digital terminal equipment automatically obtains the information data in the background when the user does not need to lock the frequency according to the information data acquisition method provided in the index information, and then...

Abstract

The invention belongs to a field of network data transmission, which provides a method and a device for sending and receiving information based on a unidirectional network. The information sending method comprises the following steps: the information data is generated to corresponding index information of information data and the index information of information data is packed into transport stream; the packed index information of the information data is sent to a digital terminal equipment; the information data is sent to the digital terminal equipment according to the index information of the information data. Based on the data carousel, object carousel or the expanding technology in the prior art, the invention adopts the method that first sending the index information of the information data, then necessary index information is selected by users and the corresponding information data with the index information is obtained in the back stage of the digital receiving terminal and stored in the digital receiving terminal so as to realize the effect of little occupation of bandwidth and a large quantity of effective information data can be sent to the users.

Description

technical field [0001] The invention belongs to the field of network data transmission, in particular to a method and device for pushing and receiving information based on a one-way network. Background technique [0002] The popularization and development of digital video broadcasting (Digital Video Broadcasting, DVB) makes it possible to obtain more information other than video, such as text information and picture information, through a digital television network. As a one-way, broadcasting network, the digital TV broadcasting network has no purpose in the way of information transmission. In this one-way transmission network, the server cannot obtain the information requested by the terminal when it needs specific information. The data is sent to the terminal, and the bandwidth is released after the data transmission is completed. Therefore, for the characteristics of this network, no matter whether the terminal needs specific data or not, the server needs to send data. ...
