Embodiment
The embodiment of the invention provides a kind of method, system, terminal and server of Frame transmitting-receiving, and the image data frame is stored Yi Bian carry out data frame transfer on one side.Because the data frame transfer of gathering also is stored in server, can not take the memory space of local terminal in a large number, so can solve the time span of Frame collection and the restriction that capacity is subjected to terminal non-volatile memory device capacity, and after the Frame collection was finished, other terminal can not in time be shared.
The method, system, terminal and the server that the embodiment of the invention are provided below in conjunction with the drawings and specific embodiments are elaborated.
As shown in Figure 1, the method flow diagram for Frame in the embodiment of the invention sends comprises:
Step S101, be that unit encodes with the frame, form coded identification the data that receive.
Concrete, after terminal collects data, with described storage in buffer memory, when the full frame of data in buffer, to the Frame formation coded identification of encoding.
Step S102, add that in coded identification specific packet header is packaged into packet.
Concrete, on coded identification, add packet header, be packaged into packet, this packet header include file name, file type, file ID, check information etc.
Step S103, the grouping of described packet is sent.
Concrete, frame data form a packet after packing, and the plurality of data bag is one group, sends via data pack protocol.
By the data that will gather after special encapsulation forms packet, grouping sends to server, can make the data of terminal collection in time store server into, solves the problem of terminal storage finite capacity, and then prolong the time of image data, and the data of collection are shared with other-end.
As shown in Figure 2, the method flow diagram for Frame in the embodiment of the invention receives comprises:
Step S201, the packet that receives is detected.
Concrete, server detects it after receiving the packet of terminal transmission, mainly is that the correctness and the integrality of packet content are carried out verification and packet is carried out authentication.
Step S202, described testing result for by the time, resolve described packet and get access to initial data frame.
Concrete, utilize result that parity check or additive method carry out verification to the correctness and the integrality of packet content for by the time, packet is carried out authentication; The result that packet is carried out authentication for by the time, packet is decoded.After decoding gets access to initial data frame, judge whether decoding is successful, and this process is finished by encoder.
Step S203, judge described resolve successfully after, store described initial data frame.Concrete, after judgement is resolved successfully, storing and resolving result data in server hard disc.
Server is by detecting and decoded data packets, and the data that the acquisition terminal is gathered are also preserved, and the data of terminal collection are shared with other-end.
Be example to shoot with video-corder audio/video information and to upload to the webserver below, Frame receiving/transmission method provided by the invention be elaborated by specific embodiment.As shown in Figure 3, comprising:
Step S301, collection audio, video data.
Concrete, same as the prior art, utilize the first-class equipment of shooting to gather audio, video data.The audio, video data that collects is stored in the buffer memory.
Step S302, described Frame is encoded.
Concrete, when described audio, video data is filled with a frame, described audio, video data is sent to codec encode.A Frame forms the respective coding symbol behind the FEC coding.
Step S303, the Frame after described encoding process encapsulation is formed packet.
Concrete, as shown in Figure 4, add specific packet header in coded identification, be packaged into packet.This specific packet header comprises a file description table, and this document description list is used to be provided at the mechanism of transmitting the various attribute informations relevant with file in the file transfer session.In this document description list, comprise: filename, file type, file ID, check information.In the process of encapsulation process, every Frame will enter the initial data stack after arriving, and first in first out encapsulates successively, in the end add in the file in the packet and finish sign, be used to explain this data packet transmission and finish.
Step S304, described packet is sent via UDP (User Datagram Protocol, User Datagram Protoco (UDP)) grouping.Grouping can be set at one group with a packet when sending.
Terminal is set up with server and is connected, and after server received the conversation request information of terminal transmission, server end continued to carry out following steps.
Step S305, server receive the packet that grouping sends, and can once receive a packet.
Step S306, the content of packet is carried out verification.
Concrete, utilize method of calibration of the prior art, as the parity check method, the correctness and the integrality of packet are carried out verification.If verification is not passed through, then to abandon current data packet, and send the current data packet re-send request may to terminal, terminal can be arranged retransmission data packet may, execution in step S305; If verification is passed through, execution in step S307.
Step S307, current data packet is carried out authentication.
If authentication is not passed through, to abandon current data packet, and send the current data packet re-send request may to terminal, terminal can be arranged retransmission data packet may, execution in step S305; If authentication is passed through, execution in step S308.
Step S308, resolve packet by verification and authentication.Concrete, packet content is decoded, and the resolution file description list, get access to original audio, video data frame.
Whether step S309, judgement decode successful.This process is finished by codec, if the decoding failure, execution in step S310; If decode successfully execution in step S311.
Whether step S310, judgement decoding number of times be greater than default threshold value.
If greater than default threshold value, abandon current data packet, and send the current data packet re-send request may to terminal, terminal can be arranged retransmission data packet may, execution in step S305; If be not more than default threshold value, execution in step S311.
Step S311, send current data packet decoding successful information, and be the file of .3gp form according to the 3GP standard handovers, and this document is stored on the hard disk of server decoded Frame to terminal.After terminal receives current data packet decoding successful information, the deletion current data packet.
Whether step S312, the transmission of judgment data bag finish.Judge in the current packet to exist when finishing sign that then whole transmission course is finished; Otherwise return step S306.
The method that provides by present embodiment can with the data of terminal collection promptly and accurately send to server, and decode successfully at server that back deleted data bag prolongs the time of terminal image data to guarantee the available storage of terminal.
