Abstract

The embodiment of the invention provides a method for playing an encrypted multimedia file and a terminal, relates to the technical field of communications, and solves the problem that when a decryption system of a terminal is unmatched with an encryption system corresponding to the encrypted multimedia file, the terminal cannot play the encrypted multimedia file. The embodiment of the invention adopts the specific scheme that a first terminal determines a second terminal which comprises a target decryption system matched with an encryption system corresponding to a multimedia file to be played, and sends a decryption request to the second terminal; the second terminal parses the decryption request to obtain first decrypted data and sends the first decrypted data to the first terminal; and the first terminal receives the decrypted data and plays the multimedia file to be played according to the decrypted data.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and terminal for playing encrypted multimedia files. Background technique [0002] At present, the multimedia files provided by most websites are encrypted multimedia files (such as video, audio, etc.) based on a software encryption system. The network link information of the encrypted multimedia file to be played, and analyze the encryption system corresponding to the encrypted multimedia file from the web page corresponding to the network link information, and then use the encryption system corresponding to the encrypted multimedia file in the terminal device The matching decryption system decrypts and plays the encrypted multimedia file. [0003] However, since different multimedia websites have different encryption systems, and for a specific terminal device, its decryption system is fixed, and different terminal devices have different decryption systems. The...
