Fig. 2 among the present invention based on the process of analysis schematic diagram of IP data in the mobile phone TV services of DVB-H standard, as shown in Figure 2, this method comprises the steps:
Step 101: obtain TV and drive the IP data that report;
Be specially, after the user selects certain TV programme of determining by the UI layer, as mentioned above, IP address that the player of television services floor is selected the user and IP version number are notified to the IP data resolution module, simultaneously dispose described IP address to TV chip, TV chip receives the IP data from the TV programme of described IP address from digital TV broadcasting network, and the IP data that receive are sent to TV drive, TV drives at regular intervals, as 2s, report the IP data one time to the IP data resolution module, the length of the IP data that at every turn report is unfixing, as long as be no more than the maximum length of setting.The IP data resolution module receives after the IP data, begins to carry out parse operation.
Here, need to prove, because it is unfixing that TV drives the length of the IP data that report at every turn, therefore in the current IP data that report, can comprise one or more complete IP messages, the residual IP data that also can comprise the IP data place IP message that the last time reports, can also comprise and be about to more top IP data of IP data place IP message of reporting next time, for example, the current IP data that report of TV driving comprise: the residual IP data of the IP data place IP message that the last time reports, a complete IP message, and more top IP data of another other IP messages.Since TV drive report at every turn and to may not be certain be complete IP message, therefore, the IP data resolution module need become complete one by one IP message by resolving the IP data splicing that will receive, specific implementation such as following steps are described.
Whether step 102: judging has residue IP data, if having, enter step 103 in the last resolving, otherwise, enter step 107;
Be specially, the trace routine in the IP data resolution module detects in the data buffer zone of described IP data resolution module whether have the IP data.If there are the IP data in the described data buffer zone, illustrate that the IP data resolution module leaves residue IP data in last once resolving, enter step 103, if there are not the IP data in the described data buffer zone, illustrate that the IP data resolution module does not remain the IP data in last once resolving, enter step 107.
Step 103 judges that can residue IP data and the current IP data that receive be spliced into complete IP message, if can, enter step 104, otherwise, step 106 entered;
Here need to prove: the residue IP data in the last resolving are generally current more top IP data of IP data place IP message that receive, and promptly comprise the information of the IP head of IP message.For the IPv4 message, its IP head has 20 bytes, and for the IPv6 message, its IP head has 40 bytes.The IP head comprises the IP message length.For making residue IP data and the current IP data that receive can be spliced into complete IP message, the IP data that need intercept certain-length from the current IP data that receive are spliced.For ease of describing, the IP data length that needs are intercepted is designated as X.The length computation that X can be deducted residue IP data by the IP message length in the IP head of the residue IP data in the last resolving draws.After the IP data resolution module is skipped preceding X byte from the current IP data that receive, whether judge follow-up setting byte number, be legal IP head as the IP data of follow-up 20 bytes (at the IPv4 message) or follow-up 40 bytes (at IPv6), Rule of judgment is as follows:
The first, judge whether to comprise legal IP version number.
Here, need point out the preceding setting bit (bits) of first byte of IP message position, as the IP version of preceding 4 bit position assigned ip messages number.If the IPv4 message, then the value of preceding 4 bit positions of first byte is 4; If the IPv6 message, then the value of preceding 4 bit positions of first byte is 6.At this moment, the IP data resolution module is according to the IP version of player notice number, whether the value that detects preceding 4 bits positions of first byte after X the byte of the current IP data that receive is corresponding IP version number, if, the IP data that setting byte number after the X byte of the current IP data that receive then is described comprise legal IP version number, may be legal IP heads.
The second, judge the MTU whether the IP message length allows less than Ethernet.
Because the IP head the 3rd to nybble, i.e. the 17th to 32bits value representation IP message length.So the IP data resolution module is resolved X byte the 3rd value to nybble afterwards of the current IP data that receive.If the IP message length value that parsing obtains, then illustrates the IP data of the X byte setting byte number afterwards of the current IP data that receive less than the MTU that Ethernet allows and may belong to legal IP head; If the IP message length value that parsing obtains, then illustrates the IP data of the X byte setting byte number afterwards of the current IP data that receive greater than the MTU that Ethernet allows and does not belong to legal IP head.
Three, judge whether the IP address is correct.
Need to prove, in step 101, it is to make the IP data resolution module confirm whether the IP data of being resolved are the needed IP data of player that player will need the IP address of the IP data that receive and IP version number to notify described IP data resolution module, purpose.Because the IP address is left in four bytes of the 16th byte (at the IPv4 message) of IP message or 24 bytes (at the IPv6 message) beginning, therefore the IP data resolution module needs according to desired location after the X byte of the IP version number current IP data that receive of parsing, as the IP address that comprises in four bytes after the 16th or 24 bytes, whether the IP address that obtains is resolved in judgement correct, promptly whether identical with the IP address of player notice, if it is identical, the IP data that the X byte setting byte number afterwards of the current IP data that receive is described may belong to legal IP head, and the current IP data that receive are the needed IP data of player.
If the IP data of the setting byte number after current X byte of IP data that receives satisfy above three conditions simultaneously, the IP data that X the byte setting byte number afterwards of the current IP data that receive is described are legal IP heads, at this moment, residue IP data in the last resolving can be spliced into a complete IP message with preceding X byte of the current IP data that receive, and enter step 104.
If the IP data of the setting byte number after current X byte of IP data that receives can not satisfy above three conditions simultaneously, promptly as long as do not satisfy arbitrary condition in described three conditions, the IP data that X the byte setting byte number afterwards of the current IP data that receive then is described are not legal IP heads, at this moment, residue IP data in the last resolving can not obtain a complete IP message with preceding X byte splicing of the current IP data that receive, enter step 106 this moment, directly abandons the residue IP data in the last resolving.
Before whether the IP data of judging the follow-up setting byte number of residue IP data are legal IP head, can judge further whether residue IP data comprise legal IP head, promptly judge from the start byte of residue IP data and begin whether to comprise legal IP head, the concrete processing as described in first three Rule of judgment, if comprise, then continue to judge whether the IP data of follow-up setting byte number are the IP head; If do not comprise, can enter step 106.
Step 104: extract complete IP message;
Be specially, the IP data resolution module becomes a complete IP message with residue IP data splicing in the last resolving before the current IP extracting data that receives after X byte.
Step 105: the process IP message obtains the mobile TV data, and sends to player, enters step 108 then;
The IP data resolution module need be with the data content in the spliced IP message, be that the mobile TV data send to player, the IP head of IP message and User Datagram Protocol (UDP) head are nonsensical for player, so in this step, IP head and UDP head that the IP data resolution module need remove the IP message obtain the mobile TV data, and the destination interface information of extraction UDP head correspondence, because different port, can distinguish different mobile TV data from same IP address, when for example playing the TV programme of certain channel, though the mobile TV data are from same IP address, voice data wherein and video data are on different port.
When the IP data resolution module sends the mobile TV data to player, because the television services layer comes deal with data according to the ICP/IP protocol stack, if the ICP/IP protocol stack is not supported the multicast form, the television services layer is to handle the data of multicast form so, therefore, after the IP data resolution module removes the IP head and UDP head of IP message, by local winding mode the mobile TV data are sent to the television services layer with the clean culture form, be specially: the local loopback address that the IP address of IP message is replaced with the clean culture form, as 127.0.0.1, be the IP address of clean culture form with the IP address transition of multicast form promptly by local winding mode, afterwards, because the current IP address after the conversion is the clean culture form, therefore the IP data resolution module sends to player with the mobile TV data with the clean culture form according to the destination slogan information of current IP address and extraction.
In this step, when the IP data resolution module sends the mobile TV data to player, can also send mobile TV data by the readjustment mode to player according to the destination slogan information of extracting for: IP data resolution module, be that the IP data resolution module is not handled multicast address, but call the processing function interface of player, the mobile TV data are sent to this processing function interface, make no matter whether the ICP/IP protocol stack supports the multicast form, player can both correctly receive the mobile TV data that the IP data resolution module sends, and then the mobile TV data that receive are handled.
By above processing, whether the ICP/IP protocol stack that just can break away from the television services layer supports the restriction of multicast form, even the ICP/IP protocol stack is supported the clean culture form, also can realize mobile phone TV services.
Step 106: abandon the residue IP data in the last resolving.
Step 107: judge that can the current IP data that receive be spliced into a correct IP message, if can, enter step 109, if can not enter step 110;
