User data information agreement (UDP) makes can directly transmit data packet between stream server 241,242,243 and the user by encoder 251,252 on IP network.
Multiple access transmits (Multicasting) and can allow content is sent to a selecteed group or several users, and for example, stream server 243 can comprise that several servers 243,244 send user 263 and 264 to multiple access.
Following narration provides the example of a further application of the invention.
The one multimedia producer prepares content of multimedia, content of multimedia may be to write down in advance or may be on-the-spot real-time, a multimedia supplier sets up or the required system architecture of combination distributing multimedia contents, the multimedia producer may be identical entity or different entities with the multimedia supplier, and multimedia supplier also prepares to help the user to programme or select channel about the channel information of content of multimedia.
In case system is established, the user can login or sign acquisition service and user and account information can be stored in lane database, user and multimedia supplier connection be and input authentication information after, their authenticity is if be proved, the user just can obtain programme information or program guide to select channel, stream server suitable when the user selects channel is also selected, content of multimedia can be begun crossfire to the user.
Because content of multimedia be with the crossfire mode in real time or near real time be transmitted, the user can produce interactive with content of multimedia, the user can have many modes to carry out this interactive effect, for example, if having seen through the internet, the user links, the user can import literal at the chat picture of computer interface, according to various channel suppliers, policy, perhaps manufacturer information, literal can occur automatically or optionally occur in a plurality of screen-pictures, this allows other user to see sender's suggestion, by this way on this channel all users each other real-time exchange information or with producer's real-time communication, so, can make contents producer change program according to user's feedback or discussion, when if those content of multimedia are film, the user can be in movie expression of opinion or the content of certain aspect of film is discussed; In another example, if content is a then educational programs, as a kind on a special subject, the user can be used as student and can be through asking or the mode of answering a question is participated in educational class.
Except that literal, the present invention can make the user with microphone or network camera provide image and voice signal to transmit, utilize this mode, those users can be as the partial content producer, as in above-mentioned then educational programs example, teacher's image will occur in the part zone of screen, individual student's image can show in the other parts of screen, make on a screen menu frame that can show a plurality of (multi-section) meeting simultaneously, comprise from a plurality of other students and teacher's image, by that analogy, can transmit sound from different users, so except the teacher, also can hear other student's sound, this virtual environment of on channel, being set up that makes just as oneself in person as for true as the scene.
The user also can see through and use the TV that a set-top box is housed to obtain similar result, perhaps, the user can utilize a cellular telephone, for example a 3G telephone receiver produces interactive effect, look the function decision that the user is equipped with, interactive effect comprises short message service (SMS) information, multimedia short message service (MMS) information, still photo, image and sound, and the user also can be through using a traditional phone to hear that the sound part of content of multimedia is to produce interactive effect in addition.

At another example, user 262 and user 263 wish to produce interactive effect with the content of multimedia of encoder 252, but, user 262 is connected different Internet Service Provider (ISP) with user 263, encoder 252 is encoded content of multimedia, see through 242 pairs of user's 262 crossfires of stream server, content of multimedia sees through stream server 242, stream server 243 crossfires to user 263, makes that so connecting heterogeneous networks ISP user shares identical interactive multimedia experience.
Expand from this example, stream server 243 comprises one group of server 243,244 again, and content can be sent to user 264 in group's mode via stream server 244.
Yet another embodiment of the invention, it can have various modification patterns among this embodiment, as can input characters or content is modified in proper order.
A multimedia producer, producer A, prepare one group of film, for example one group France film, film may be encoded and be stored on a server or the stream server, a multimedia supplier, supplier B, set up system architecture and comprised Core server, stream server, web page server and encoder, a user, user C signature obtains service, when user C wants to watch content of multimedia, and user C accessing system and their user data of input, authentication server confirms the data of user C input, in case obtain to confirm, user C connects web page server to check stored programme information, and wherein program can be via master server, available server, policy IP or other standard and layout form.
User C is interested in and select to check the content that producer A provides French film, and after selecting this channel and film, stream server begins the film crossfire to user C.
The example that more complicated again expansion is above-mentioned, producer A also provides French film to appreciate forum, a Movie Reviewers holds forum, many users: user C, user D, user E and user F, want to participate in forum, each user is connected network camera their computer with microphone, in case forum meeting begins, each user's sound and signal of video signal are encoded and crossfire each other between other user and those Movie Reviewers' computer, in addition, film is given each user by crossfire, all these signal of video signal can or be presented on the independent screen in a plurality of parts of screen, the layout of screen can be selected by the producer or quilt other user individual, in addition, the Movie Reviewers can control the signal of which sound and be heard by other user, for example, if user C wants to ask topic, the presider can allow user C audio frequency be listened to.
And when the film crossfire, each user can see through literal transmission connection with presider and other user and be, for example, when cin positive film was shown, those users and presider can propose about the suggestion of a special scene or movie contents is discussed.
In the above-mentioned whole session, master server sends the heartbeat package and keeps an available server directory to stream server with continuation, and by this way, if there is any stream server to reduce, the user can be changed to another stream server automatically.
For example, stream server in its present selected use of the user C of the U.S. is worked as machine, master server directs into another available stream server to user C automatically according to user C, policy or IP address, in this example, master server is selected one near near the available strings streaming server the user C.
Obviously, a lot of variations may be applied to above-mentioned example, and for example, content, number of users, supplier, location of content or the like may be changed or require and make an amendment according to adapting to.
The above is by characteristics of the present invention are described by embodiment, its purpose is had the knack of this operator and can Liao be separated content of the present invention and implement according to this making, and non-limiting the present invention's claim, so, all other do not break away from equivalence modification or the modification that disclosed spirit is finished, and must be included in the claim of the following stated.
