Abstract

The invention discloses a file transmission system combining a broadcast and television net and an internet, aiming at solving the technical problems that data transmission efficiency is improved and bandwidth is avoided to be wasted. The file transmission system combining the broadcast and television net and the internet is provided with a database server, a file processing server, a front end system, a terminal device and a file server, wherein the terminal device is connected with the front end system through the digital broadcast and television net and the internet; the file processing server is connected with the database server, the front end system and the file server through the internet; the file server is connected with the terminal device through the internet; the to-be-transmitted file of the front end system is saved in the database server; and a file processing system is arranged in the file processing server; and a file receiving system is arranged in the terminal device. Compared with the prior art, the file transmission system has the advantages that a path for obtaining file data from the terminal device is added, the file data can be obtained through a broadcast link, and the file data can be obtained from the internet through network connection.

Description

technical field [0001] The invention relates to a data transmission system, in particular to a file transmission system using the broadcasting network and the Internet. Background technique [0002] With the continuous strengthening of TV terminal functions, the extension of applications, and the characteristics of low broadcast transmission costs, in TV broadcast data, in addition to traditional information such as audio and video streams and program guides, data of file type, such as text, will also be transmitted. Pictures, audio and video files, etc., to meet the application of music, movies, teaching image push and advertisement delivery. Compared with audio and video streams, files belong to block data and have higher requirements for data integrity. The lack of data blocks in files will rendering the entire file unusable. At present, there are already some applications for transmitting files in broadcasting, such as news, file downloading, etc., and the technology us...
