Embodiment 1

[0034] refer to figure 1 , an IP-type intelligent set-top box of the present invention uses a main chip with advanced security functions inside, and integrates a live broadcast application module, a virtual tuner set on the system software hardware abstraction layer built in the set-top box, a demultiplexing module, and a demultiplexing module. Interference module, data processing center application module. The application module of the data processing center connects at least one of the live application modules and the front-end system platform to realize unified management of all live applications.

[0035] The live application module is used to obtain the IP data stream from the front-end system platform. If the IP data stream is encrypted, it will be sent to the virtual LNB. If the IP data stream is unencrypted, it will directly call the player to play.

[0036] Specifically, the acquisition of the IP data stream by the live application module from the front-end system pl...

Embodiment 2

[0042] Based on the same inventive concept, the present invention also constructs a video playing method, based on the IP-type intelligent set-top box of Embodiment 1, said method comprising:

[0043] S201: The live broadcast application module obtains the IP data stream from the front-end system platform, and if the IP data stream is encrypted, sends it to the virtual LNB, and if the IP data stream is unencrypted, directly calls the player to play.

[0044] Specifically, the live application module obtains the IP data flow from the front-end system platform, including:

[0045] 1) The live broadcast application module sends a playback request to the data processing center application module;

[0046]2) The data processing center application module sends an authentication request including set-top box information and playback content to the front-end system platform according to the playback request;

[0047] 3) The front-end system platform performs authentication according ...

Abstract

The invention discloses an IP type intelligent set-top box and a video playing method thereof, the set-top box comprises a live broadcast application module, a virtual tuner, a demultiplexing module and a descrambling module; the live broadcast application module is used for acquiring an IP data stream from a front-end system platform, and sending the IP data stream to the virtual tuner if the IPdata stream is encrypted; a virtual tuner which is arranged in a system software and hardware abstraction layer arranged in the set top box and is used for converting the encrypted IP data stream intoa transport stream and injecting the transport stream into the demultiplexing module; a demultiplexing module which is used for demultiplexing the injected transport stream and injecting CA information obtained by demultiplexing into the descrambling module; and a descrambling module which is used for descrambling the CA information and sending the descrambled audio and video streams to the livebroadcast application module for playing. In this way, the IP set top box can achieve smooth playing of the IP multicast streams encrypted by the CA.

Description

technical field [0001] The invention relates to the field of set-top boxes, in particular to an IP-type intelligent set-top box and a video playing method thereof. Background technique [0002] Live content security has always been the most important security broadcasting requirement in the broadcasting industry. With the current trend of the overall broadcasting industry converting to IP, the content protection requirements for IP live video are also becoming more and more urgent. With the help of the country's long-term promotion of commercial encryption technology development and implementation policies, some operators have begun or plan to adopt CA methods (such as DCAS, downloadable conditional access system) for the content encryption of current IP live video content. [0003] The specific implementation process of the CA method is to perform CA encryption on the TS stream (Transport Stream, transport stream) of the live program received from the satellite or cable, a...
