As shown in Figure 3, for the beholder, the implementation method of fast wireless network remote control of the present invention sports system comprises the steps:
(1) authentication: the user submits identity information to controlling on the computer, and this identity information is sent to central server, and central server carries out authentication to this identity information;
(2) application is watched in submission: the user watches application to controlling the computer submission, central server carries out spectators' registration, if the spectators of registration are that (all spectators need registration and login to senior spectators VIP, whether and to distinguish according to its paying situation in login process be senior spectators VIP), the authority of subscribing to video is arranged, then the place server is subscribed to video, and direct broadcasting room carries out subscribing notification;
(3) on-the-spot broadcasting: remote-control toy is dispatched first visual angle audio frequency and video (first visual angle, be called subjective visual angle again, the first visual angle audio frequency and video promptly by camera in remote-control toy emulation driving cabin, visual angle with the emulation driver is taken, and the audio frequency and video that obtain), camera scheduling place, place audio frequency and video, direct broadcasting room carries out audio frequency and video integration adding and separates the related data of mediating a settlement, and will integrate audio frequency and video and be uploaded to the place server, the place server carries out the audio frequency and video buffering, central server carries out the audio/video flow distribution according to subscribing to authority, controls computer and watches relevant audio frequency and video, finishes.
By browser interface, the user can be real-time see many group audio/video informations (directly by the camera collection on the remote-control toy to audio/video information, the audio/video information that the place collects, and the field data that the host explains orally in the direct broadcasting room).
There are attendant, judge, the live personnel of explanation in the scene, for various services are carried out in athletic competition.
It is limited that each play can be participated in the number of sports, and much other users can watch athletic competition by the mode of internet video live broadcasting.
Adopt following technology in the inventive method:
1. the server video is cut apart and splicing
Transmission of video signals need take massive band width.For the conserve bandwidth that can try one's best, so that more user can onlinely be watched, the present invention adopts multi-channel video to integrate splicing.The user can see three kinds of video informations according to the role, is respectively: by the camera collection on the remote-control toy to video information, the video information that the place picture pick-up device collects, and the live video information that the host explains orally in the direct broadcasting room; Control the player, the video-splicing mode that can own setting need see, for example, can set only see by the camera collection on the remote-control toy to video information, also can set by the camera collection on the remote-control toy to video information as main video, the live video information that the host explains orally in video information that the place picture pick-up device collects and the direct broadcasting room is as embedding video or auxiliary video; General Visitors are merely able to see the splicing scheme of several videos that direct broadcasting room is set; Senior spectators VIP can limited subscription oneself wish the video information seen, and splice.
As shown in Figure 4, video of the present invention adopts many shot segmentation technologies, is divided into main video, embeds video and auxiliary video.The present invention adopts video splitting scheme freely, can make up needed various video information freely at the diverse location of screen, also can open a unsteady window on main video window, embeds the embedding video that is only second to main video on some importance.According to common video location attention rate, the video of most critical normally is placed on the position of main video, and being placed on of next embeds in the video window, the auxiliary video zone that then is placed on periphery that it is wanted again.The people that authority is arranged can freely select the form cut apart and the content of each block.There is the people of authority to refer to: the instructor in broadcasting and senior spectators VIP that control player, direct broadcasting room the inside.
All collect, the video source information that the someone subscribes to, and just the information that directly arrives by camera collection is all passed through the signal broadcasting that Video service (special services that the place server is provided) is carried out multiple precision.When client received the information of these broadcasting, the preferential signal that receives low precision under the situation that bandwidth allows, re-used high-precision signal and further plays up on the basis that low precision is played up.Set according to the picture splicing that this locality is set, the precise information of the big viewing area of an acceptance video, the divided video picture of those less area coverages, only the video packets of precision is hanged down in acceptance.
The online transmission means of existing video is carried out subpackage according to time slice substantially and is handled.Promptly, video is divided into a lot of time slices, each time slice is by diverse network transmission means (server to client end P2S, peer client P2P or server client mixing P2SP) be delivered to client, client is carried out assembly unit and buffer memory, and when downloading, the part of having received is played to the client.The present invention can adopt the mode of carrying out burst according to time slice, video area and quality.Be the extra fine quality of the specific region of special time period, the burst transmission.The preferential low precision content that transmits main video area or generation particular event zone, transmit the high-precision signal of main video area then, transmission has the high-precision signal of particular event generation area again, client is after receiving these information, play in real time, some regional information quality is not high or imperfect, directly hides with low precision video, original picture or certain alternative picture.Guarantee under the situation that lowest-bandwidth needs, main video information, or have the video of particular event generation area to be seen as early as possible by the client.
2. multichannel voice frequency mixed transport
According to user's needs, multipath audio signal according to weight, is organized on the different distance and position.Audio-frequency information can be set on the different virtual locations by the different delayed time of volume and left and right acoustic channels.After a plurality of sources of sound were gathered, these signals can carry out set positions according to importance, the position of source of sound collecting device itself and the specific incident of user's setting, video information that audio frequency is relevant.The a plurality of sound that make the user to hear to send on the diverse location, and the user can also pass through the position, judges a specific audio-frequency information, by which source of sound is sent, and the concrete implication of its representative.The people be by about two ears hear time difference of same sound, judge the source of sound particular location.As shown in Figure 5, the present invention uses the surround sound technology, the source of sound that difference is collected, be rendered into different positions and get on, when allowing the people can hear these sound, the source of telling alternative sounds, and when some source of sound has particular event to take place, amplify its volume.Accomplish to allow the people who listens as far as possible, can hear the auditory tone cues that all are important.
3. authentication and control instruction and encrypt
Because this is the sports entertainment selection that numerous Internet users are given in an opening, have a large number of users and pay close attention to, but have only small number of users just can reach the standard grade and control.User's authentication and control the encryption of instruction just seems particularly important.The data volume of controlling information should be unable to be very big, can adopt the higher enciphering and deciphering algorithm of relative safety to handle.After these orders were received in the website, the website was to the transmission between the server of place, and the place server has carried out complicated encryption to the transmission between the remote-control toy with regard to not needing.All audio frequency and video feedback informations do not carry out encryption and decryption and handle.
Have a lot of informational needs to carry out encrypted transmission, current three kinds of encryption technologies commonly used all have obvious defects.The HASH method, most economical, the most quick, but can only carry out unidirectional conversion.Can't realize the dual work of encryption and decryption, normally standby be used as password when preserving unidirectional verification instrument use.The symmetry encipher-decipher method, fast, employed key is consistent during still owing to encryption and decryption, when needing deciphering, just key must be propagated, this process is difficult to the safety of assurance key.And symmetric encipherment algorithm also has a drawback, and that is exactly that whole data segment adopts same key to encrypt, as long as key has been cracked, then the fail safe of whole data segment has not just all ensured yet.Asymmetric encipher-decipher method, encryption and decryption use public-key respectively and private key.Wherein PKI can only be used for encrypting, and private key can be used for encryption and decryption.When needing encrypted content, only propagate PKI at every turn.Even PKI has been blocked, also can't be decrypted enciphered message.This method is to carry out in the distributed encryption and decryption calculating process a kind of relatively fail safe at present than higher method, and still, the speed of this mode and cost be unusual height all, is difficult to just promote on a large scale.Usually be used on the high security, small data quantity business of bank.The key of asymmetric encryption, generative process, and the initial key transmission and the mode of disseminating have determined the asymmet-ric encryption method fail safe, if this step can't effectively ensure the safety of data transmission of entail dangers to integral body then to safety.
Current most cryptographic algorithm all is that these three kinds of modes are merged, and uses different modes to encrypt for the different step or the process of transfer of data.The present invention adopts the higher cryptographic algorithm of relative safety, and it is higher to refer to relative cost, and efficient is relatively poor, but the asymmetric preferably enciphering and deciphering algorithm of fail safe.
This is a kind of new sports entertainment way, by the minority player, directly controls at the remote-control toy of sealing in the place by the Internet.Explanation, work service personnel and judge by the scene carry out various auxiliary cooperations at the scene.A large amount of spectators by the net cast of the Internet, watch participation.
The present invention can be applied in the various remote-control toy recreation, for example:
1. online entity racing car
