Problems solved by technology

[0002] Ordinary playback device or claim playback terminal, specifically as: multimedia player, multimedia public playback terminal, player all does not have security protection function to the program that will play, because usually the program of playback terminal itself exists in the open FLASH ( FLASH is a memory that can be read) and can be read at will, which makes the playback terminal itself unable to prevent pirated copying, that is, under the premise of imitating the use of the same circuit, just copy the FLASH chip and put it on the circuit board.
[0003] As for the programs to be played by the players, they are mainly protected by encrypting the program data on the disc at present. Once they are copied or decrypted, they can be played unlimited times and indefinitely on all corresponding players. Free download and playback on the Internet will disrupt the operation of the entire market and cause huge losses to program developers and operators

Abstract

The playing back equipment includes one or more intelligent terminals as well as one or more intelligent keys in use for security. At least one intelligent key is as a security module, which is not possible to be replicated completely. Intelligent keys are divided into user type intelligent keys to denote usersí»ID and / or internal intelligent keys to denote ID of intelligent terminals. At least one intelligent terminal is connected to one or more intelligent keys. In condition of intelligent key is presented, intelligent terminal can process, transfer data or plays data of program. Intelligent key controls playing program. Content server has designed perfect methods for controlling display of local program, display of down loaded networked program, and display of online network program. The invention provides technical safeguard for further networked programs in multimedia.

Description

technical field [0001] The present invention relates to a playback device, in particular to an intelligent digital content playback device provided with an intelligent key, and also to a controllable and safe playback method for program data by the above playback device. Background technique [0002] Ordinary playback device or claim playback terminal, specifically as: multimedia player, multimedia public playback terminal, player all does not have security protection function to the program that will play, because usually the program of playback terminal itself exists in the open FLASH ( FLASH is a kind of memory that can be read) and can be read at will, which makes the playback terminal itself unable to prevent pirated copying, that is, under the premise of imitating the use of the same circuit, just copy the FLASH chip and put it on the circuit board. [0003] As for the programs to be played by the players, they are mainly protected by encrypting the program data on the...
