Embodiment Construction

[0030] figure 1 Shown is a kind of on-board audio-visual file transmission system of the present invention, and this system comprises:

[0031] Air video server 1 and wireless playback terminal 2;

[0032] Described air video server 1 comprises:

[0033] The caching module 12 is suitable for caching data processed by preset data processing rules to reduce the space occupied by the data;

[0034] The server receiving module 11 receives the request for accessing data from the wireless playback terminal 2;

[0035] The data search module 13 is adapted to call the cache module, and according to the request, find whether there is corresponding response data processed by the preset data processing rules in the cache module;

[0036] The encapsulation module 14 is adapted to encapsulate the response data to generate a response message if the corresponding response data exists in the cache module;

[0037] The wireless output module 15 is adapted to return the response message to ...

Abstract

The invention provides an encryption transmission method of onboard audio and video files. The invention has advantages and beneficial effects as follows that (1) aerial rapid and massive audio and video data transmission is realized basing on a wireless WLAN technique, aerial individual entertainment demands of passengers are satisfied; (2), an audio and video file server caches the resource data of processing the response data according to a preset data processing rule so as to reduce the data occupied space through a cache module in advance; the aerial audio and video server can directly provide response data to the client through the cache module, the client access speed can be clearly improved; (3), a user can conveniently and visually play various audio and video files at various terminals, the problem of copyright protection of television contents is solved through DTCP encryption, the copyright owners such as content merchants can share the charged audio and video files safely; (4), the safety and privacy of the entertainment system can be promoted through portal authorization.

Description

Technical field [0001] The invention relates to the field of the Internet, in particular to a method for encrypting and transmitting video and audio files on a machine. Background technique [0002] Air vehicles (such as airplanes) are usually equipped with data communication equipment to enable passengers to watch video movies, listen to music or surf the Internet during the journey. Conventional passenger entertainment systems typically include overhead cabin video systems or seat-based video systems with individual controls so that viewing content can be selected by the passenger. Viewing content may include audio content and video content originating from a variety of content sources. Internal content sources (eg, audio players and video players) installed on the vehicle can provide pre-recorded viewing content (eg, movies and music). [0003] Due to the limited bandwidth allocated by the current in-flight entertainment system, multicast transmission is adopted for ord...
