Embodiment
Describe cooperation drawings and Examples in detail embodiments of the present invention below, by this to the present invention how application technology means solve technical problem and the implementation procedure reaching technology effect can fully understand and implement according to this.
embodiment one
Please refer to Fig. 1, in general, when remote controller 2 needs what's new or repairs damage, just need to write upgrade file at remote controller 2, make remote controller 2 can control intelligent television 1 smoothly.Therefore, the invention provides transmission and method of reseptance upgrade file is transferred to the remote controller 2 with its pairing from intelligent television 1.The method of transmission of the present invention and reception upgrade file, can verify the integrality of received upgrade file.Below will be described in detail.
Please refer to Fig. 2, the flow chart of its display first embodiment of the present invention: the method flow diagram of transmission upgrade file, it comprises following steps.
Step S21: upgrade file is divided into multiple subfile according to preset rules.
Further, upgrade file can be sent to local intelligent television 1 by first distally server end, and this upgrade file is divided into multiple subfile according to the byte number of predetermined quantity by intelligent television 1.Preferably, this upgrade file is split into multiple subfile comprising 32 bytes (byte).Namely intelligent television 1 reads 32 bytes of upgrade file is a unit (subfile), sequentially reads upgrade file.But usually due to the multiple that the size of upgrade file is not 32 bytes, so when assigning to last subfile, data volume is not enough to reach 32 bytes, after filling up data, also leave a lot of rooms, at this moment these rooms are filled up with 0, finally obtain the subfile of 32 bytes.The cutting techniques adopted in the embodiment of the present invention can be usual in prior art dividing method, do not repeat them here.
Step S22: each subfile is packaged into respectively corresponding transfer of data bag.
In this step, each subfile can be packaged into a corresponding transfer of data bag, and multiple subfile then can be packaged into the transfer of data bag of multiple correspondence.
Step S23: by host-host protocol, is transferred to remote controller with its pairing according to Preset Transfer order from this intelligent television by each transfer of data bag, synthesizes described upgrade file carry out upgrading processing for described remote controller in this locality.
Preferably, this host-host protocol is 2.4G host-host protocol.Each transfer of data bag is transferred to remote controller with its pairing according to transmission sequence from this intelligent television with single-threaded.
For the ease of the verification (being described in further detail in the embodiment two of method receiving upgrade file below) during receipt of subsequent, the present invention is while being transferred to the remote controller with its pairing from intelligent television by each transfer of data bag, or before, or afterwards, first the information of upgrade file total capacity can be sent to remote controller from intelligent television.Also can send the information of the quantity of transfer of data bag to remote controller from intelligent television further.These two information can simultaneously or asynchronous transmission.In addition further, please refer to Fig. 3, each transfer of data bag 3 comprises capacity region, sequence area 32, one 33 and a data field 34; Further, each transfer of data bag 3 also comprises a tag slot 31.Sequence area 32, except having the sequence number of identification order, also includes discrimination bit.Whether the recognizable current transfer of data bag of discrimination bit is last transfer of data bag.
Tag slot 31 is used to identify this upgrade file, the unique identification of this upgrade file (normally the mark of 2 byte positions) can write in tag slot 31 when encapsulation of data transmission package 3 by transmitting terminal (intelligent television 1), transfer of data bag 3 is received like this at receiving terminal (remote controller 2), can first recognize tag slot 31, be confirmed whether the transfer of data bag into upgrade file.
The order of sequence area 32 each transfer of data bag recognizable, transmitting terminal (intelligent television 1) can be that each transfer of data is responsible for assigning sequence number according to sending order when encapsulation of data transmission package 3, and sequence number being write in the sequence area 31 of each transfer of data bag, such sequence number just can be used for differentiating these transfer of data bags.Because receiving terminal (remote controller 2) not necessarily order receives each transfer of data bag 3, after receiving transfer of data bag, can recognize whether the transfer of data bag that receives has repetition by sequence area, can also recognize whether lack transfer of data bag by sequence area in addition, can also be retransmitted to the transfer of data bag of transmitting terminal (intelligent television 1) request with regard to corresponding sequence number by the sequence number in sequence area if lacked.About the integrality of checking data transmission package, describe in detail in the embodiment receiving the method for upgrade file down below again.
33, capacity region is the amount of capacity of single transmission packet after record encapsulation, and this capacity region can be used for verifying the integrality of each single transmission packet.
34, data field is for storing the content-data of the subfile of segmentation, and the size of the content-data stored in this data field 34 is 32 bytes at the present embodiment.
The present invention, by the method for transmission upgrade file, makes upgrade file be divided into be convenient to the transmission packet of complete reception, and can be sent to remote controller from the transmission that intelligent television is complete, thus make remote controller can complete upgrade file smoothly.Further describe for the method receiving upgrade file below, and illustrate how to verify received transmission packet.
embodiment two
Next please refer to Fig. 5, second embodiment of the present invention---receive the method for upgrade file, it comprises:
Step S51: the transfer of data bag being received multiple host-host protocol transmission by presetting by wireless network.
Preferably, each transfer of data bag be by 2.4G host-host protocol from this intelligent television with the single-threaded remote controller being transferred to pairing.But multiple transfer of data bag of the present invention is not limited to the remote controller being transferred to pairing from this intelligent television, namely, multiple transfer of data Bao Yike is from smart mobile phone or computer transmission to the remote controller of pairing.The present embodiment preferably above-mentioned first embodiment of single-threaded received in sequence splits the transfer of data bag of rear package, namely each transfer of data bag is encapsulated by the segmentation subfile of 32 bytes (byte) to form, each transfer of data bag 3 comprises capacity region, sequence area 32, one 33 and a data field 34, its function is described above, therefore it is no longer repeated.
Next need to judge whether transfer of data bag receives complete.Here complete reception has two layers of meaning, the whether complete reception of the first each transmission packet, and it two is whether all transfer of data bags receive all.What first detect below is when receiving single transmission packet, the whether complete reception of single transmission packet.
Perform step S52: judge whether the transfer of data bag be currently received receives complete.
In this step, when receiving transfer of data bag, first the tag slot 31 of the transfer of data bag be currently received being detected, recognizing the transfer of data bag of the transfer of data bag that is currently received whether upgrade file.If detected by tag slot 31 and find that the transfer of data bag be currently received is not the transfer of data bag of upgrade file, illustrate that the transfer of data bag be currently received does not have complete reception, then perform step S58.
In this step, when receiving transfer of data bag, also to judge whether the capacity of nominal in the actual size of received transfer of data bag and the capacity region of transfer of data bag conforms to.Namely, transmitting terminal (intelligent television) before sending transfer of data bag can first calculated data transmission package capacity (size) and first write the capacity region of transfer of data bag, during reception, receiving terminal (remote controller) is also the actual capacity (size) first calculating received transfer of data bag, then compared with the capacity (size) of nominal in capacity region.If when judging that the capacity of transfer of data bag is not identical with the capacity (size) of capacity region, just represent that transfer of data bag is not intactly received, then perform step S58.
If detected by tag slot 31 and find that the transfer of data bag be currently received is the transfer of data bag of upgrade file, and the capacity of nominal conforms in the actual size of the transfer of data bag received and the capacity region of transfer of data bag, illustrate that the transfer of data bag be currently received is the transfer of data bag of upgrade file, and the transfer of data bag be currently received intactly is received, then perform step S521.
Step S58: the transfer of data bag (not being received if lack transfer of data bag, then without the need to abandoning) of not complete reception described in abandoning, and the transfer of data bag again transmitting not complete reception to transmitting terminal (intelligent television) request.The sequence number in this transfer of data packet sequence district 32 is carried, so that transmitting terminal (intelligent television) knows which transfer of data bag of this repeating transmission in the request sent.Then return step S51, receiving terminal (remote controller 2) receives the transfer of data bag of repeating transmission again.
Step S521: temporal data transmission package, and perform step S53.
In the temporary memory block of remote controller, the transfer of data bag of the temporary integrity authentication through step S52 received.
Step S53: judge whether to receive all transfer of data bags completely.
Sequence area 32 according to transfer of data bag 3 judges, namely, described sequence area 32 more comprises discrimination bit, is used for indicating last transfer of data bag.。Therefore, receiving terminal receives transfer of data Bao Kecong sequence area 32 to determine whether last.Utilize single-threaded sequential delivery, when received transfer of data bag is last transfer of data bag, just represent that all transfer of data Bao Douyi are done reception.
Certainly a kind of situation is also had, in single-threaded sequential delivery process, the situation having packet loss or make a mistake, in this case often need to retransmit, therefore cause transmitting is not likely in order, but upset, now wrap in last transfer of data of packing the record done sequence area 32 simply by virtue of transmitting terminal and go to detect whether complete transmission is inadequate, because the transfer of data bag whether not yet retransmitted in addition after this transfer of data bag can not be confirmed whether.Therefore need to receive and the transfer of data bag of keeping in detects all the temporary memory block of remote controller, whether the sequence number detecting these transfer of data bags is continuous whole, and to have the transfer of data bag of " last " discrimination bit in sequence area 32 as end.Such as, the discrimination bit of the sequence area 32 of last transfer of data bag is set to " 0 ", and the discrimination bit of the sequence area 32 of other transfer of data bags is set to " 1 ".If the sequence number of these transfer of data bags is continuous whole, then can guarantee to receive all transfer of data bags completely.Simultaneously by process that whether sequence number of these transfer of data bags of above-mentioned detection is continuous whole, the transfer of data bag that sequence number repeats can also be found out, and by verifying the data content of transfer of data bag thus the transfer of data bag duplicate removal that will really repeat.
If step S53 is judged as "No", do not receive all transfer of data bags completely, the transfer of data bag currently may not receiving and make to have " last " discrimination bit in sequence area 32 is described, obviously now transfer of data bag does not also transfer, although be also likely have received the transfer of data bag making to have " last " discrimination bit in sequence area 32, but lost some transfer of data bags by detecting discovery, now need to ask the transfer of data bag to losing to retransmit, then perform step S58.
If step S53 is judged as "Yes", guarantee to receive all transfer of data bags completely, then perform step S54.
Step S54: merge all transfer of data bags, forms upgrade file at this remote controller.
By the transfer of data Packet analyzing of keeping in memory block is corresponding subfile in remote controller side, and merging according to resolving all subfiles obtained, being combined to form upgrade file.
Step S55: complete checks is carried out to the upgrade file formed in step S54.
Except judging whether (verification) individual data transmission package has intactly received and all transfer of data bags whether to be intactly received, whether the present invention also verifies the upgrade file after merging all transfer of data bags further complete, and the content merged misses transfer of data bag.
In this step, receiving terminal (remote controller) is resolved the actual all transfer of data bags received, calculate the content-data in data field 34 in each transfer of data bag, reject in particular for 0 filling part in data field 34 in last transfer of data bag, then these content-datas are calculated summation.
In addition, before issuing transfer of data bag, receiving terminal (remote controller) has received the information of the total capacity of the upgrade file that need transmit from transmitting terminal (intelligent television).
Compare calculating the information of the summation of trying to achieve the content-data received with the total capacity receiving the upgrade file that need transmit, if both conform to (namely step S55 is judged as "Yes"), just illustrate and define complete, correct upgrade file, then perform step S56.If both do not conform to (namely step S55 is judged as "No"), just illustrate and do not define complete, correct upgrade file, then perform step S57.
Step S56: by complete upgrade file write remote controller, install in remote controller.
Step S57: the upgrade file that obtains will be merged and delete, and by the temporary memory block of remote controller the total data transmission package of keep in delete, return step S51, receiving terminal (remote controller 2) asks again to receive all transfer of data bags.
Because file of the present invention is split into the subfile of 32 bytes, during verification, only need comparison summation, therefore without the need to too many calculation resources.Verification can be completed faster, and then upgrade file.In addition, by the verification of twice, transmission of the present invention and method of reseptance can provide more accurately complete upgrade file, for user, can have simpler and easy and accurate experience.
