Specific embodiment

Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure It is fully disclosed to those skilled in the art.

Referring to Fig.1, a kind of step flow diagram of according to embodiments of the present invention one video monitoring method, institute are shown The method of stating can specifically include following steps:

Step 101, the video stream data for being directed to monitored object is received.

Method described in the embodiment of the present invention is applied to the scene that there is the video stream data transmitted with streaming manner.

Monitored object can be for prison for the target object that user monitors in advance, the received video stream data of network server Control the data that object is recorded, the data specifically recorded for monitored object region, for example, preset monitored object is A certain safety cabinet within doors, video stream data are the data recorded for safety cabinet region.Network server receives video flowing It uploads the video stream data of end transmission and respective handling is carried out to it, called for Terminal Server Client.

Method described in the embodiment of the present invention can be applied to several scenes, such as apply in long-range monitoring scene, video Other scenes such as live scene, video transmission scene, different scenes correspond to different video flowings and upload end.

When being applied to long-range monitoring scene, monitored object can be static object, such as indoor article, and video flowing uploads end It can be the remote monitoring end with camera function, such as long-range monitoring camera；When being applied to net cast scene, monitoring pair There is the welcome guest of live streaming permission as can be after main broadcaster ratifies, video flowing, which uploads end, can be the client where welcome guest.

Step 102, judge whether to need to carry out slicing treatment to the video stream data.

Video stream data is recorded for monitored object, and monitored object is likely to be at normal condition, it is also possible to based on hair It gives birth to special event and is in abnormal condition.

The special event that monitored object occurs can be that special dynamic change, prison occur for the static scene where monitored object One of special dynamic change and other events or a variety of occur for control object itself.For example, in long-range monitoring scene, prison The special event that control object occurs can swarm into indoor gate for stranger, stranger opens safety cabinet etc.；In net cast field Uncivil behavior etc. can has occurred for welcome guest in Jing Zhong, the special event that monitored object occurs；In video transmission scene, monitoring The special event that object occurs can be a variety of, such as corresponding to monitoring scene, net cast scene or other scenes it is special Event.

When special event occurs for monitored object, it is that alarm operation is executed to monitoring user as early as possible, keeps monitoring user timely Know that special event has occurred in monitored object, network server is receiving the video for monitored object in the embodiment of the present invention After flow data, received video stream data can be analyzed, if it is decided that special event occurs for monitored object, it is determined that prison Control object is in abnormal condition, at this moment needs to carry out slicing treatment to the video stream data, and execute subsequent step；If sentenced Determine monitored object and be in normal condition, then caching or other operations is carried out to the video stream data.

It may include a variety of for determining whether monitored object occurs the method for special event according to video stream data, for example, working as When special event occurs for monitored object, instruction monitored object can be carried in the video stream data of upload, the pre- of special event occurs Bidding knows or instruction, after network server recognizes the default mark or instruction of video stream data carrying, determines corresponding monitoring Special event has occurred, in abnormal condition in object, further determines that needs carry out slicing treatment to the video stream data；Net Network server can judge whether monitored object has occurred special event by identifying the frame picture of video stream data, and then judge Whether need to carry out slicing treatment to video stream data.It can also include other applicable judgment methods, the present invention is not done herein Limitation.

Step 103, if so, being video flowing segment for the video stream data cutting and transmitting the video flowing segment To Terminal Server Client.

Determining monitored object generation special event, after needing to carry out slicing treatment to video stream data, network server Slicing treatment is carried out to received video stream data, correspondence obtains video flowing segment.It when specific operation can be according to preset rules Video stream data is sliced, such as preset video flowing piece size, video flowing clip durations etc..Network server later Resulting video flowing segment is sent to Terminal Server Client, checks user to special event in time.

After generating first video flowing segment, first video flowing segment is sent to remote client by network server End, at this moment user can start to check the special event that monitored object occurs, as video flowing segment is continuously generated, Video flowing segment is constantly sent to Terminal Server Client.Therefore, it is to be viewed special for occurring to substantially reduce user etc. for this method The time for the video content that the monitored object of different event is recorded, improve user experience.

The case where for network server better performances, can limit lesser video stream data size or duration, so The video flowing segment called and played for Terminal Server Client can be generated as soon as possible, shorten the video to be viewed such as user when Between, improve user experience.

Terminal Server Client can be the terminal for being equipped with video player, such as mobile phone, plate, computer, TV etc..Remote In range monitoring scene, Terminal Server Client can be monitoring mobile phone used by a user, plate etc.；In net cast scene, far Journey client can be other terminals used in live streaming terminal or main broadcaster used in main broadcaster, and main broadcaster can be according to video flowing The content of segment adjusts the permission of welcome guest, such as cancels welcome guest's permission and become ordinary user；When applied to video When relaying scene, Terminal Server Client can be live streaming terminal used in monitoring mobile phone used by a user, main broadcaster etc..

According to an embodiment of the present invention, the video stream data for monitored object is being received, determined according to video stream data After special event occurs for monitored object, judgement needs to carry out video stream data slicing treatment, and correspondence obtains video flowing segment, and Gained video flowing segment is sent to Terminal Server Client.The method Terminal Server Client is without waiting for video flowing through the invention Data upload terminates, the video ready to receive for occurring to record when special event to monitored object in video stream data upload procedure Flow data substantially reduces the waiting time of user, and efficiently solve video stream data checks delay issue, improves user Experience.

Referring to Fig. 2, a kind of step flow diagram of according to embodiments of the present invention two video monitoring method, institute are shown The method of stating can specifically include following steps:

Step 201, the video stream data for being directed to monitored object is received.

Step 202, whether judge in the frame data head of the video stream data received with the instruction monitored object hair The special instruction of raw special event, wherein if having special instruction in the frame data head, it is determined that need to the video flowing Data carry out slicing treatment.

In the embodiment of the present invention, video stream data is recorded for monitored object, and video stream data uploads end and will regard Frequency flow data is uploaded to before network server as unit of frame, special event whether can be occurred to monitored object and be analyzed, If it is determined that special event has occurred in monitored object, then addition indicates monitored object in the frame data head of video stream data The special instruction of special event, special instruction can be diversified forms, such as special identifier, be sliced to video stream data Action command etc., the special identifier in different frame data head can be the same or different.

By taking long-range monitoring scene as an example, write in advance for judging whether monitored object occurs the program of special event, and The program write is mounted in remote camera, when being monitored using remote camera to monitored object, if it is decided that prison It controls object and special event occurs, then it is special to add in the frame data head for the video frame that the initial time that special event occurs is recorded Video frame added with special instruction is sent to network server by instruction.In other videos recorded for the special event Special instruction is added in frame.

Correspondingly, network server can analyze video stream data after receiving video stream data, if it is decided that The special instruction of special event occurs in the data head of video stream data with instruction monitored object, it is determined that need to video flowing Data carry out slicing treatment.

Step 203, if so, being video flowing segment for the video stream data cutting and transmitting the video flowing segment To Terminal Server Client.

After determining and needing to carry out slicing treatment to video stream data, video stream data is sliced as video flowing segment, and And generate the broadcast address of the video flowing segment.In order to allow monitoring user to know that special event, net has occurred in monitored object as early as possible Network server notifies the broadcast address to Terminal Server Client after the broadcast address for generating video flowing segment.

Terminal Server Client can be shown or execute preset warning operation after receiving the broadcast address to it with logical Know monitoring user, can be with click play address, correspondingly if the corresponding video data of monitoring user's pre-review, network clothes Business device can receive the play instruction that Terminal Server Client is triggered based on broadcast address, and video stream data is sent to remote client later End, while video stream data can also be stored in corresponding server for subsequent calls and checked.If network server is not It receives the play instruction of Terminal Server Client, such as does not receive play instruction within a preset period of time, then it can be by video flowing Segment is stored in corresponding server.Wherein, it can be for saving the server of video flowing segment to the progress of video flowing segment The server for receiving and being sliced, is also possible to be specifically used to store the server of video flowing segment, can also be other servers, The present invention is herein with no restrictions.

Server can divide user gradation in advance in practice, and user gradation is higher, corresponding to video flowing segment exist Storage time in server is longer.For some private services devices, the use of user can be determined according to the purchase amount of money of user Family grade.Terminal Server Client has client identification, when server can be with pre-recorded client identification-user gradation-storage Between corresponding relationship check and use for subsequent.

It can be uploaded in video flowing and the long-range of specified transmission is stored in advance in end (such as remote monitoring end, net cast end) Given client end mark is added in video stream data in uploaded videos flow data, makes to regard by the client identification of client Frequency flow data carries the client identification of the specified Terminal Server Client sent.Correspondingly, network server is being received for monitoring After the video stream data of object, can according to client identification determine Terminal Server Client belonging to user class, further also Storage time prison can be carried out to the video flowing segment of storage according to the storage time being set separately for different user rank The video flowing segment for reaching setting storage time is deleted in control.

Video pictures group (Group of Pictures, GOP), a GOP are exactly one group of continuous picture.In MPEG In (Moving Picture Experts Group) coding standard, picture is divided into I frame, and (intra picture, inside are drawn Face), P frame (predictive-frame, forward-predictive-coded frames) and B frame (bi-directional interpolated Prediction frame, bi-directional predicted interpolation coding frame), the group for belonging to multiple continuous frames an of picture is collectively referred to as regarding Frequency picture group, such as IBBPBBPBBPBBPBBP.

As unit of video pictures group, video flowing segment can be made of at least one video pictures group.In slice video When flow data, received video stream data can be parsed as unit of video pictures group, by least one continuous view Frequency picture group is stored as video flowing segment.

Network server receives the video stream data transmitted by frame, is made based on reasons such as frame-skipping, network delays There may be timestamp offsets between received video frame, and timestamp offset, which will lead to multiple video frames, continuously to play, and lead Multiple video flowing segments are caused not play continuously, to reduce user experience.

To solve the above problems, guaranteeing that the multiple video flowing segments stored in server and multiple video frames can continuously be broadcast It puts, the embodiment of the present invention can also be handled to different video flow section and to the problems in video flowing segment video frame.

It specifically, can be to each video flowing segment during video flowing segment is stored in corresponding server Association identification is added, multiple continuous video flowing segments are associated with according to association identification, and associated video flowing segment is formed back Video file is put, playback video file is stored in corresponding server.Wherein playback video file may include one or more A video flowing segment.

For playing the Terminal Server Client for playing back video file after recognizing video flowing segment and carrying association identification, to pass Connection identifies corresponding video flowing segment and is unconditionally played, to ensure that the continuous broadcasting of multiple video flowing segments, guarantees The continuous broadcasting of playback video file.Wherein, association identification can be serial number, temporal information, associated previous video At least one of segment and associated latter video clip.

Video stream data is much information, such as temporal information to be carried in each frame, according to piece according to video frame transmission Segment identification is associated with before multiple continuous video flowing segments, is also based on the temporal information of video frame carrying, searches video flowing The problem of temporal information shifts in the video pictures group of segment video frame, later repairs problem video frame, thus It ensure that the normal play of video flowing segment.

Video stream data uploads end and presses frame uploaded videos flow data, and the time interval between two adjacent video frames is very It is short, for example, time difference between two adjacent video frames be less than 1s, if video frame is normal when uploading and in upload procedure, The problems such as there is no time migrations, then the time difference between the received two adjacent video frames of network server is constant；If Serious problems occur when upload and in upload procedure, cause video frame that biggish time migration occurs, then network server connects Time difference between the two adjacent video frames of receipts becomes very large；If occurring slightly to ask when uploading and in upload procedure Topic, leads to that lesser time migration occurs, then the time difference between the received two adjacent video frames of network server can become larger, But the amplitude that becomes larger is smaller.

The embodiment of the present invention can preset the time difference threshold value between two adjacent video frames.Work as two adjacent video When time difference between frame is less than time difference threshold value, it may be said that non-time of origin offset between bright two adjacent video frames, or Illustrate between two adjacent video frames that time of origin deviates, but the time migration occurred be within an acceptable range, will not be right Presentation of video frames causes to seriously affect；When the time difference between two adjacent video frames exceeding time difference threshold value, it may be said that bright Received video frame is problem video frame there are biggish time migration, rear received video frame afterwards.Therefore, video flow is searched It can be by searching for super with the time difference of a upper video frame the step of video frame the problem of time migration in the video pictures group of section The method of the video frame of given threshold is realized out.

It include at least one video pictures group in video flowing segment, the picture frame in video pictures group includes I frame and P frame, I frame in one video pictures group is adjacent with the P frame in a upper video pictures group, the last one in a video pictures group P frame is adjacent with the I frame in next video pictures group, different function and present position based on I frame and P frame, and the present invention is implemented Example uses different restorative procedures to I frame and P frame.Therefore, before being repaired to problem video frame, it is also necessary to decision problem The type of video frame is I frame or P frame.

For a video pictures group, if it is decided that problem video frame is P frame, since P frame is forward predicted frame, although going Except P frame picture will appear the main situation of card, but there is also blank screen, user still can continue to watch, then right to picture do not occur In the P frame that the restorative procedure of P frame can be contiguous therewith for deletion P frame and below.For example, a video pictures group is (I P P P P P P P P), if the 5th P frame is problem video frame, delete the 5th P frame and its subsequent continuous multiple P Frame, the video pictures group after reparation are (I P P P P).

It include multiple video pictures groups in one video flowing segment, in a video flowing segment, if problem video frame There is also other video pictures groups behind the video pictures group at place, then according to the above method deletion ask P frame and below with After its continuous P frame, in the presence of the I frame in the last one P frame and next video pictures group in the video pictures group after reparation Between deviate so that two video pictures groups can not normal play.

To solve the above problems, guaranteeing that the video pictures group after repairing and adjacent next video pictures group are normally broadcast Put, the embodiment of the present invention can to after reparation video pictures group and adjacent next video pictures group carry out slicing treatment, Obtain two video flowing segments；Association identification is added to video flowing segment later, player is after recognizing association identification, to two A video flowing segment is continuously played.
