Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
The present invention provides a kind of method obtaining electric program menu, and with reference to Fig. 1, in one embodiment, the method for this acquisition electric program menu includes:
Step S101, CAM card is set up with digital intergrated unit and is connected, and is stored from acquisition electric program menu data front-end server by described digital intergrated unit；
In the present embodiment, digital intergrated unit is connected by the hardware interface specified with condition reception (ConditionalAccessModule, CAM) card, it is possible to carry out data communication.Digital intergrated unit and CAM card can be realized respectively by different hardware and software platforms, and in practical service environment, digital intergrated unit can interact from the CAM card of different providers, it is necessary to process the complex situations occurred in work process.
Wherein, digital intergrated unit includes client and general-purpose interface (CommonInterface, CI) protocol stack, wherein, client is to communicate mutual background application with front-end server, and CI protocol stack is that digital intergrated unit is specifically designed to the part interacted with CAM card.
In the present embodiment, owing to CAM card does not possess network communications capability, therefore after CAM card and digital intergrated unit are set up and be connected, CAM card by digital intergrated unit from front-end server getting electric program menu data and storing.
In the present embodiment, CAM card obtains electric program menu data from front-end server in real time, these electric program menu data are according to obtaining time order and function sequence, because CAM card limited storage space, therefore, preferably, after arriving a time cycle, delete electric program menu data, and preserve newer electric program menu data.
In the present embodiment, digital intergrated unit obtains electric program menu data from CAM card, it is essentially and obtains up-to-date electric program menu data, be so easy to user and watch current program but it also may the electric program menu data according to the customer requirement retrieval correspondence time.
What deserves to be explained is that the digital intergrated unit of the present embodiment is for realize quick obtaining electric program menu based on Android operation system, is certainly not limited to Android operation system, other operating systems can also make similar scheme.
Step S102, after digital intergrated unit is again started up, when receiving the instruction obtaining electric program menu data of user, is sent to described CAM card by the instruction obtaining electric program menu data；
In the present embodiment, user is started shooting again by plug-in, or is again started shooting by power key by remote controller.User inputs the instruction obtaining electric program menu data on digital intergrated unit, after receiving this instruction, the client of digital intergrated unit sends the instruction obtaining electric program menu data to CI protocol stack, and CI protocol stack sends the instruction of these acquisition electric program menu data by ordering to CAM card.
Step S103, described CAM card obtains corresponding electric program menu data according to described instruction, acquired electric program menu data is sent to described digital intergrated unit, obtains the electric program menu data of needs for user in time.
In the present embodiment, CAM card beforehand through digital intergrated unit from front-end server getting electric program menu data and storing, after digital intergrated unit is again started up, the instruction that CAM card sends according to digital intergrated unit obtains stored electric program menu data, is then sent to digital intergrated unit.
In the present embodiment, particularly as follows: CAM card transmits EPG data to CI protocol stack, CI protocol stack sends the client of digital intergrated unit to EPG data.
Wherein, CAM card needs to issue the EPG data of front-end server with comms_send () APDU (minimum unit of low-speed communication) to the transmission of CI protocol stack, CI protocol stack is stored among the buffer memory buffer of corresponding phase_id (phase bit number) after receiving data, call socket_send () (pipeline transmission) and send EPG data, often distribute the data inside a buffer memory buffer, inform which buffer of CAM card is for empty and next available with comms_reply () (communication response).
Additionally, client adopts select (selection) to go to monitor front-end server according to the socket_fd (pipe handle) created, when the EPG data listening to front-end server, call socket_rcv () (conduit acceptor) and obtain EPG data, and be sent to CI protocol stack.After CI protocol stack receives EPG data, comms_rcv () (low speed communication receives data) is adopted to send EPG data in the buffer memory buffer of the corresponding available phases numbering phase_id of CAM card, CAM card sends comms_cmd (getnextbuffer) (receiving next buffer) message after having processed EPG data, inform that the EPG data of which buffer memory buffer of digital intergrated unit has processed and next available.
The present embodiment need not obtain EPG data from transmission stream, therefore the message of front-end server and PSI/SI message need not be carried out reciprocal monitoring, and transmission stream is carried out a series of process just can get EPG data, flow process is simple, it is not necessary to wait the longer time；The present embodiment can start in latter 2 seconds at digital intergrated unit and presents new EPG, is improved more than at least 6 seconds the waiting time of the prior art, is greatly improved the experience of user.
