The application example of the invention is to unify songs in a cloud server of a KTV set-top box into torrent files, store the torrent files in the cloud server, compile LibTorrent (LibTorrent is a BitTorrent development library in C + + language and supports Linux/Unix system) into executable files inside the set-top box, then start a daemon process to control downloading and seeding, each set-top box calculates the seed number according to the memory/load of the set-top box, then download the corresponding torrent files like a server, the server takes the more recently downloaded hotspot songs to obtain the InfoHash of the song (the unique identification of the file in an InfoHash BT network, the specific attribute of the file, calculated during seeding and written into a torrent seed file), and continuously communicate with a Tracker server according to the InfoHash in the process of starting downloading roles and downloading BT of the Tracker server, to report its own information and obtain information of other download clients) to determine whether to continue to make seeds, if the number of make seeds is higher than a certain threshold, the file does not continue to make seeds in the set-top box, otherwise, the file is downloaded to make seeds, if the set-top box downloads the song, the set-top box pulls the seed file of the corresponding song from the cloud to download, if no connection is available within 10 seconds and the number of bytes downloaded is 0 or the average speed within one minute is less than 100KB, the P2P download is closed, and the CDN download is started.
Compared with the prior art, the method for acquiring the new song by the household KTV set-top box is downloading from the cloud server, and is low in downloading speed, high in cost, high in pressure on the server and required to be supported by a CDN manufacturer. According to the application example of the invention, LibTorrent and cloud Tracker are deployed in all set top boxes to form a private BT network to balance the seeding of songs, so that the server pressure is reduced and the bandwidth cost is reduced. The method can establish a private BT download network to carry out balanced seeding according to more downloaded hot songs, and the advantage of BT download is utilized to enable the song or MV download to be faster and more stable.
