Description

Distribution method and device, equipment and storage medium

Technical Field

The embodiment of the invention relates to the technical field of Internet Protocol Television (IPTV), in particular to, but not limited to, a distribution method, a distribution device, equipment and a storage medium.

Background

At present, a content provider of Internet Protocol Television (IPTV) has a very strict requirement on protecting content injected into an IPTV system, and the content injected into the IPTV system must be encrypted and decrypted when a user plays the content. Using conventional Digital Rights Management (DRM) encryption technology and players is expensive, increasing the cost for the operator. The Google (Google) video optimization software (widget), the Apple (Apple) video optimization software (Fairplay), and the Microsoft (Microsoft) video optimization software (Playready) have free DRM and corresponding open native players, which are integrated in various terminals and browsers, such as International Organization for Standardization (ISO) related devices, Android related devices, video game machines (XBOX), web page (Chrome) browsers, web page browsers (Internet Explorer, IE), and web page browsers (Enhanced Rate for GSM Evolution, EDGE). This can significantly reduce the cost of the operator and the cost of the user. However, since these DRMs are independent DRM mechanisms of three manufacturers, each DRM can only support a corresponding device or browser, and cannot support ISO-related devices, Android-related devices, XBOX, Chrome browser, IE, Edge browser, etc. that are mainstream in the market. Meanwhile, the DRM cannot perform security control on the terminal accessing the system and the right to view the content, which may cause illegal access of the terminal and illegal playing of the content.

EXAMPLE six

The embodiment of the invention can enable the IPTV system to simultaneously support various mainstream terminals or browsers in the market, and can safely control the terminal accessing the system and the permission watching the content.

The embodiment of the invention is based on three DRM mechanisms of Widevine, Fairplay and Playready, and integrates the three DRM mechanisms into a Multiple Digital Rights Management (MDRM) so as to support various mainstream terminals or browsers in the market; the security control can be performed on the terminal accessing the system and the right to view the content. When playing the content, the terminals of different types judge whether the content is encrypted, if the content is encrypted, the MDRM system requests a playing License (License). The MDRM system can authenticate whether the request is initiated by the authorized terminal or not according to the request message. If the request is initiated by the authorized terminal, whether the MDRM system has access capability or not and whether the ID allows the MDRM system to access the system or not are judged according to the terminal address (ID) information. And if the MDRM system has access capability and is a legal terminal ID, authenticating the content viewing authority to the IPTV middleware system according to the terminal ID. If the authentication is passed, generating playing License according to the request message, and if the terminal is a Widevine type terminal (such as a mobile phone, a pad, a set-top box and the like of an Android system), generating corresponding playing License through a Widevine plug-in; if the terminal is a Fairplay type terminal (such as a mobile phone, a pad and the like of an ISO system), generating a corresponding playing License through a Fairplay plug-in; if the terminal is a Playready type terminal (such as IE, Edge browser, etc.), a corresponding Playlicense is generated through a Playready plug-in. And if the License is successfully generated, returning the corresponding License, and playing the encrypted content by the terminal through the integrated corresponding DRM plug-in and native player.

Through the embodiment of the invention, the IPTV system can support various terminals and browsers, such as ios equipment, safari browser, android equipment, chrome browser, IE, Edge browser and the like, which are mainstream in the market, and the terminals accessing the system are ensured to be authorized and have the authority to watch related contents.

here, the format of the authorization information is BASE64(AES ("authorization code | device ID | timing", key)), BASE64 is one of the most common encoding modes for transmitting 8-Bit byte codes on the network; advanced Encryption Standard (AES); device ID refers to device address; a timestamp (timestamp), a complete, verifiable piece of data that can represent a piece of data that existed before a particular time, usually a sequence of characters, uniquely identifying the time of a moment; the key refers to a key.

Step S604, the copyright license server determines whether the authorization information passes the authentication according to the authorization information;

here, if the authorization information authentication is not passed, an invalid License is returned; if the authorization information passes the authentication, go to step S605.

Step S605, if the authorization information passes the authentication, the copyright license server manages the current access capability according to the equipment address and the multiple digital copyright, and checks whether the terminal allows the access to the system;

if the system is not allowed to be accessed, returning an invalid License; if the access to the system is allowed, go to step S606.

Step S606, if the terminal allows to access the system, the copyright license server network element authenticates the terminal watching content right to the network protocol television middleware;

if authentication fails, returning failure information to the terminal; if the authentication is passed, the required data is taken out from the request message, the content and the decryption key information are inquired from the memory database (Dcache), if the inquiry in the memory database is not available, the inquiry is carried out in a data management (Postgres) database, and if the inquiry is not available, the failure information is returned. The queried data is used to generate a play License (License).

Step S607, the copyright license server uses different digital copyright management plug-ins to generate play license according to the types of different terminals;

here, if the terminal is a widget type terminal, generating a corresponding playing License through a widget plug-in; if the terminal is a Fairplay type terminal, generating corresponding playing License through a Fairplay plug-in; if the terminal is the Playready type, the corresponding Playlicense is generated through the Playready plug-in.

Step S608, if the generation of the playing license is successful, returning the generated license to the terminal;

and step S609, the terminal plays the encrypted content through the digital copyright management plug-in and the native player integrated by the equipment by using the returned license.
