Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0027] Such as figure 1 As shown, the embodiment of the present invention provides a data receiving method for a satellite user terminal, including:

[0028] Step 101, the ground server sends the file data to be pushed to the satellite, and the ground server records the original file information of the file data;

[0029] Step 102, the satellite receives the file data, and broadcasts the file data to the ground through broadcasting;

[0030] Step 103, the ground monitoring terminal receives the file data, and at the same time the ground monitoring terminal records the received file information of the file data, the ground monitoring terminal connects with the ground server through the Internet, and sends the received file information to the ground se...

Abstract

The invention discloses a data receiving method for a user terminal of a satellite. The method includes the steps that firstly, a ground server sends file data needing to be pushed to the satellite and records primary file information; secondly, the satellite receives the file data and broadcasts the file data to the ground; thirdly, a ground monitoring terminal receives the file data, records received file information, is connected with the ground server and sends the received file information to the ground server; fourthly, the ground server obtains file information which is missed alone by comparing the primary file information with the received file information; fifthly, all file information which is missed alone is compared, file information which is missed together partially is obtained, and files which are missed together partially are determined according to file information which is missed alone; sixthly, the ground monitoring terminal which receives the files which are missed together partially sends the files to the other ground monitoring terminals which do not receive the files which are missed together partially.

Description

technical field [0001] The invention relates to satellite communication technology, in particular to a data receiving method for a satellite user terminal. Background technique [0002] Satellite digital distribution is a new publishing model, which uses satellite networks to directly deliver digital products such as audio and video, electronic books (newspapers, magazines, books), games, software, and industry information to user terminals with receiving and playing capabilities. service, and conduct copyright authentication and management when users use it. [0003] The existing satellite digital distribution process is that after the legally published digital publications are encrypted, the data is first sent to the satellite through the ground server, and then the satellite pushes the data to the user terminal in the form of broadcast. After authentication and decryption, Users browse applications through computers, TV screens, portable terminals and other devices. Sat...
