Abstract

The invention provides a video and audio playing device and a player which are suitable for the multimedia field. The device comprises a key unit, a control unit, an encrypting-decrypting unit and a playing unit. In the invention, the video and audio playing unit is provided with the encryption function, changes the prior condition that media data can only be encrypted in a media server and distributes the key which is originally preserved just in the media server of a seller to the video and audio playing device. The media server has no information safety problem, thus the seller can enlargesale network, which can promote the sale of media products.

Description

technical field [0001] The invention belongs to the field of multimedia, and in particular relates to an audio-visual playing device and a player. Background technique [0002] At present, the sales of media products are all made by media providers, encrypted by the media server of the seller, and then sold to consumers. Media terminals such as consumers’ audio-visual playback devices decrypt the media data and play them. . figure 1 It is a structural block diagram of an existing audio-visual playback device 100'. The control unit 102' in the playback device stores the media data downloaded from the computer 300' into the storage unit 105' through the interface unit 101'. These media data come from the Internet. The media server 200' has been encrypted by the media server 200', so these media data must be decrypted by the decryption unit 103' in the audio-visual playback device 100' before being sent to the playback unit 106' for playback. But because this audio-visual pla...
