Application data-downloading method, digital television receiving terminal and system

Abstract

The embodiment of the invention discloses an application data-downloading method. The method comprises: sending a request for application list version numbers to application download proxy servers in digital television systems; receiving a latest application list version number returned by the application download proxy servers in the digital television systems according to the request for application list version numbers; performing analysis and comparison to see whether a local list version number is identical with the latest application list version number; sending application download requests to different digital television systems if the local list version number is identical with the latest application list version number; and sending a request for acquiring updated application data to application download servers in the digital television systems if the local list version number is different from the latest application list version number. The embodiment of the invention also discloses a digital television receiving terminal, an application management system and a digital television system. The load of networks and application download servers is reduced by implementing the invention.

Description

technical field [0001] The invention relates to the communication application field, in particular to a method for downloading application data, a digital TV receiving terminal, an application management system and a digital TV system. Background technique [0002] Existing digital TV receiving terminals generally download the application list from the application download server in the digital TV system through the Hypertext Transfer Protocol (HTTP), and compare the application list with the local application list to determine whether to update the application or upgrade. figure 1 A flow chart of a method for downloading application data by a digital TV receiving terminal in the prior art is shown, which specifically includes the following steps: [0003] S101: The digital TV receiving terminal requests an application list from the application download server through a timing loop mechanism; [0004] S102: The application download server returns application list data to t...
