Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment belongs to the range of the application protection.
Refering to fig. 1, Fig. 1 is the flow diagram of the transmission method first embodiment of the application video, present embodiment packet
Include following steps:
S110: the network terminal is treated transmitting video data using setting agreement and is encoded, to obtain video counts to be transmitted
According to protocol data-flow.
In the present embodiment, the network terminal, need to be to be transmitted to this first before transmitting to collected video data
Video data handled so that it is converted to the data flow that can be used for being transmitted by standard network transport protocol,
So as to effectively be parsed and played.It will be appreciated that the network terminal treats transmitting video data, using presetting
Standard agreement encoded, can be used for being transmitted by standard network transport protocol to obtain the video data to be transmitted
Protocol data-flow.
In an optional embodiment, setting agreement can be H.264 high compression digital video coding-coding device mark
Quasi- agreement, the network terminal can transmit H.264 video flowing using RTP real-time transport protocol, then it will be appreciated that network
Terminal first carries out collected original video data to be transmitted using H.264 high compression digital video coding-coding device standard
Coding, to obtain corresponding H.264 code stream, to further RTP real-time transport protocol be used to be transmitted.
In the present embodiment, the network terminal can be the corresponding data processing terminal equipment of video capture equipment, can also be with
It is corresponding network server terminal etc., the application does not limit this.
S120: the correspondent time information of video data to be transmitted is inserted into the supplemental enhancement information list of protocol data-flow
Member, to generate the supplemental enhancement information with timestamp information.
In the present embodiment, by taking video data to be transmitted is encoded as H.264 video flowing as an example, H.264 video flowing is being adopted
When being transmitted with Real-time Transport Protocol, need unix millisecond timestamp when synchronous transfer each I frame acquisition video frame, then it is found that
To video data to be transmitted accordingly H.264 video flowing when, need further to believe the corresponding timestamp of the video data to be transmitted
Breath is inserted into H.264 video flowing, correspondingly, because H.264 the data Network Abstraction Layer NAL of video flowing includes to add enhancing letter
Interest statement member, SEI unit, thus supplement to data information in the SEI unit and modification can be effectively prevented from transformation RTP transmission association
View, to ensure effectively to transmit corresponding timestamp information under the premise of not changing the versatility of data stream transmitting.It is intelligible
It is that transmitting video data is treated using H.264 agreement in the network terminal and is encoded, and it is corresponding to obtain video data to be transmitted
H.264 when video flowing, the corresponding timestamp information of the video data to be transmitted is further inserted into the supplement of H.264 video flowing
Enhancement information unit, in SEI unit, to generate the supplemental enhancement information with timestamp information.
In the present embodiment, the network terminal is also needed the information in supplemental enhancement information unit according to standard transmission protocol
General Requirement is inserted into the general setting position of protocol data-flow, for example, to adapt to the general transmission of RTP transport protocol sequence,
SEI information in supplemental enhancement information unit need to be inserted into IDR (the Instantaneous Decoding of H.264 video flowing
Refresh, instantaneous decoding refresh) before information, so that subsequent be able to carry out effectively is transmitted and is decoded.
S130: the protocol data-flow for being inserted into timestamp information is sent to intelligent terminal, so that intelligent terminal is to reception
To protocol data-flow parsed, play video data to be transmitted after obtaining timestamp information.
