Description
Technical field
The present invention relates to the reception of the business datum of Mobile Multimedia Broadcasting, relate in particular to a kind of method of reseptance and device of electron service instruction data.
Background technology
The mobile media broadcasting network user is when using mobile multi-media broadcasting service, by electron service instruction (ESG, Electronic Service Guide) or electronic program guides (EPG, ElectronicProgram Guide) navigation, understand the relevant information (comprising Business Name, reproduction time, content outline and price etc.) of mobile multi-media broadcasting service, and realize quick retrieval, preview and visit business.ESG is for user's TV reception and enjoy information service a good navigation mechanism is provided, and makes the user can find the program of own care, the additional information of checking program quickly and easily.In the CMMB mobile multimedia broadcast system, electron service instruction mainly is made up of following information or data:
(1) basic descriptor is used to describe the version and the ESG information transmitted of electron service instruction, just the data directory information of electronic program guides;
(2) ESG data message is used for as the key data of describing electron service instruction, promptly is used to the information of the business of describing, content and playing programs advance notice and Operational Visit parameter;
(3) program prompt information is used to predict current channel and is playing and be about to the programm name of broadcast and the information of duration.
During mobile multimedia broadcast receiving terminal work, need the working frequency points receiving multimedia broadcast signal of search mobile media broadcasting network, to use multi-media broadcasting service, electron service instruction also is one of them multi-media broadcasting service.Terminal equipment receives electron service instruction data when the user provides professional navigation, at first need to receive the basic descriptor of ESG, obtain comprising the content such as the network information, frequency point information, service identification of ESG business, find the transmission channel at ESG data message place then according to these contents, comprise multiplexed frame sign and multiplexed sub frame, the data message that receives ESG at last represents to the user.
Be illustrated in figure 1 as the system block diagram of the ESG information of CMMB Mobile Multimedia Broadcasting, this system is based on the CMMB network and constitutes.According to the CMMB technical system, the CMMB system and forms one or more independently mobile media broadcasting networks because the service geographic range is different with radiation pattern, wherein:
The basic descriptor of ESG is that the basic description list of ESG, service allocation list are encapsulated in the multiplexed frame 0 as the control information table respectively with the service configuration information of whole network, and is modulated at the control logic channel of each frequency, as shown in Figure 2; Wherein, basic descriptor comprises the network information (network number, network title and network-level) and ESG additional information; The network information is used to represent the network of current ESG work; The ESG additional information comprises: the data type and the version number of service identification information, ESG data message; Wherein, service identification is used to obtain multiplexed frame sign and Physical Broadcast Channel parameter (as: modulation parameter, coding parameter, interlace mode or the like); Service configuration information comprises: the corresponding relation of service identification and frequency.
The ESG data message is encapsulated in the data segment of specific multiplexed sub frame of non-0 multiplexed frame, and is modulated on the service logical channels of above-mentioned specific frequency and transmits, as shown in Figure 3.
Program prompt information and sound, video data are encapsulated in respectively in the data segment, audio section, video-frequency band of the multiplexed sub frame of non-0 multiplexed frame together, and the service logical channels that is modulated at each frequency transmits, as shown in Figure 4.
Based on said system, CMMB terminal ESG Data Receiving handling process referring to Fig. 5, comprises the steps:
Step 100b: the user selects or searches for a CMMB network by the CMMB terminal;
Step 200b: the frequency of user in the frequency of CMMB terminal selection current network work enters;
Step 300b:CMMB terminal selects the control logic passage of frequency to receive basic description list of ESG and service allocation list from the user;
From the basic description list of ESG, resolve and the basic descriptor of record ESG, comprise the information such as service identification of data place service logical channels of data type, version and corresponding these data types of ESG data message; From service allocation list, inquire about the certain tones dot information of carrying ESG data message according to service identification.
Step 310b:CMMB terminal switches to the service logical channels of above-mentioned specific frequency according to the parameters such as service identification of ESG data, handles ESG data message to receive (perhaps upgrading);
Promptly at first in service allocation list, determine the specific frequency of work by service identification, and switch to and receive multiplexing allocation list on the control logic passage of this specific frequency, in this multiplexing allocation list, inquire corresponding specific multiplexed frame sign according to service identification again and (wherein also comprise the multiplexed sub frame sign in each multiplexed frame, if no special instructions, the sign of multiplexed frame described in the application all comprises the multiplexed sub frame sign in this multiplexed frame), and, from this specific multiplexed sub frame data segment, extract the ESG data message in conjunction with this service identification corresponding physical broadcast channel parameter that receives.
Step 320b:CMMB terminal parses ESG data message also shows that the user navigates, selects to use the service of mobile multi-media broadcasting service in view of the above.
As seen above-mentioned reception flow process is the processing mode of serial, and the parameter of the service logical channels of ESG data is obtained in the reception of carrying out the basic description list of ESG of need taking time, and utilizes these parameters to receive the ESG data then.
Because the basic descriptor of ESG need receive on the control channel of Mobile Multimedia Broadcasting, and the ESG data message transmits on service logical channels, programs such as TV transmit on another service transmission channels, according to above-mentioned method of reseptance, when terminal equipment receives the ESG data, need between different receive paths, often switch, switch the meeting elapsed time, thereby can influence the inbound pacing of terminal equipment and normally watching of user, if avoid the influence of switching, usually need terminal can receive the data of 2 or above passage simultaneously, the requirement that can strengthen the disposal ability of terminal increases the cost of terminal.
