Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
The invention provides a kind of traditional network television direct broadcasting system that is different from, this system can be the media industry such as TV station, radio station, papers and magazines mechanism, school, Party and government offices etc. provides Video over IP to broadcast solution, and watching online of video content is provided.For providing the network teleconference, Internet video, other enterprises and institutions such as each radio, TV and film industries mechanisms, government bodies, army of school the service such as watch, and the direct broadcast service of competitive sports, party, momentous conference.Technical development along with three nets (being TV, broadband and radio network) fusion, the broadcast channel of TV station's video frequency program is also day by day abundant, except conventional television is broadcasted mode, the terminals such as mobile phone, computer, mobile TV are to the broadcast demand of content also expanding day.Therefore, adopt the network direct broadcasting system based on stream media technology, can effectively solve by the Internet or enterprises dedicated network and realize realtime video transmission, the demand of watching simultaneously to satisfy net cast, interaction and many picture angle.
Be elaborated below by embodiment.
With reference to Fig. 1, it is the structure chart of the described a kind of network television direct broadcasting system of the embodiment of the present invention.
Described network television direct broadcasting system mainly comprises:
Streaming Media signals collecting server 1 be used for from programme signal source Real-time Collection primary flow media signal, and coding generates the live streaming media file;
The Streaming Media signal is included server 2, is used for from programme signal source Real-time Obtaining live streaming media file, and flows the section buffer memory; Described stream section buffer memory is that each key frame of live streaming media file is set up index;
Streaming medium content transmission server 3 is used for including server from the Streaming Media signal and obtains the live streaming media file, and real-time Transmission is play to network player.
Wherein, described Streaming Media signal is included server 2 and is used for realizing including live front early stage, includes the live streaming media data from the Streaming Media signals collecting server 1 as the signals collecting end, and is distributed to network player by streaming medium content transmission server 3.Described network player is as the webpage client, for the user provides the streaming media playing service.
Include server 2 for the Streaming Media signal, the present embodiment is from the different of prior art:
Direct broadcast server end of the prior art does not all carry out buffer memory to the data of whole live process, but the current partial data for playing of buffer memory only, so prior art can't realize the direct playing and playback function.But, the described Streaming Media signal of the present embodiment is included server 2 and can all is buffered in all data of live process in server, like this, the user is when watching live video, if missed certain section just now live content, perhaps think again to watch just now live wonderful, can back drag the progress bar of player, at this moment this player has just sent playback request to streaming medium content transmission server 3.Streaming medium content transmission server 3 can be included the live streaming media file that server obtains buffer memory from the Streaming Media signal, passes to player and carries out direct playing and playback.And the duration of video playback only is subjected to the restriction of server buffer capacity, therefore in the situation that the server buffer capacity is enough large, can realize the direct playing and playback of any duration.
In addition, described Streaming Media signal is included server 2 when carrying out buffer memory, has also adopted the stream microtomy.Described stream microtomy refers to when the live file of stored stream media, each key frame in file be set up index, and preserves index, can be directly targeted to the position of certain key frame in file by this index.Based on described stream microtomy, the Streaming Media signal is included server 2 can be according to the time point of playback request, find key frame corresponding to this time point by index in the live streaming media file, then directly begin reading out data from this key frame position, rather than read whole file.Therefore, network player also can directly ask the time point of playback to begin played data from the user, the user does not need to take time and waits for transmission and the broadcast of this key frame previous contents, content that just can directly arbitrary time point begins to watch playback from live video.
For described Streaming Media signals collecting server 1, the present embodiment has also been optimized the signals collecting encoding function.In actual applications, traditional encryption algorithm as H.264 or MPEG-4 more advanced much than MPEG-2, MJPEG etc., larger reduction code stream, still, but easily cause on the contrary the slack problem of picture under low bandwidth.This be because: MPEG series compression algorithm has adopted the pattern of I frame, P frame and B frame, and wherein, the I frame is key frame, and the P frame is forward predicted frame, and the B frame is the back forecast frame.The mpeg decode process is as follows: receive an I frame when decoder, can decode at once, and not need other condition.But, when decoder is received P frame or B frame, just can not decode at once, such as, the decoding of P frame needs decoder first decode P frame or the I frame of this frame front.If the P frame of front or I frame are lost in network, even the back is received a lot of P frames continuously, also can't normal decoder.For example: lose an I frame in the inadequate situation lower network of bandwidth, even P frame subsequently all receive, still can't be correctly decoded the picture of publishing picture.Here it is why under low bandwidth MPEG4 or H.264 the compression algorithm performance not as good as the reason of MJEPG.
For these reasons, the described Streaming Media signals collecting of the present embodiment server 1 provides a kind of solution thinking: increase the probability that in cataloged procedure, key frame occurs, make decoder receive within a certain period of time more key frame, like this, even because the frame losing phenomenon appears in network problem, because decoder can be received next key frame within the shorter time interval, the broadcast of therefore can decoding immediately, thus solved the long-time problem of stagnating of picture.
With reference to Fig. 2, it is the structure chart of described Streaming Media signals collecting server 1.Described Streaming Media signals collecting server 1 can comprise:
Signal acquisition module 11 is used for from programme signal source Real-time Collection primary flow media signal;
Encoder 12 is used for described primary flow media signal coding is generated the live streaming media file, and offers the Communications service module, adjusts in real time according to the network bandwidth probability that in the live streaming media file, key frame occurs in cataloged procedure;
Communications service module 13 is used for becoming the form of network transmission package to be distributed to the Streaming Media signal described live streaming media file declustering and includes server.
In the present embodiment, the interval that described encoder 12 produces by reducing key frame increases the probability that in cataloged procedure, key frame occurs.In MPEG series encryption algorithm, usually use this value of GOP (Group Of Picture) that the interval that the I frame produces is set.So-called GOP, the meaning is the picture group, a GOP is exactly one group of continuous picture.If the current network bandwidth is good, encoder 12 can arrange the GOP value according to common empirical value.But if the current network bandwidth is too low or the network bandwidth is indefinite and unstable, encoder 12 can be adjusted to the value of GOP a less desired value, and is corresponding, and the interval that the I frame produces diminishes, and just can increase the probability that in cataloged procedure, the I frame occurs.For example, one group of frame of video comprises 15 frames, supposes that every 4 frames are I frames, has 3 I frames; The interval of I frame is reduced to 2 frames, has 5 I frames, the I frame has increased by 2 frames.Like this, if can produce a plurality of I frames 1 second, even lost once in a while an I frame, next I frame also can make up very soon, and image is unlikely to long stagnation.
Preferably, in order further to guarantee fluency that the user browses and the quality of video image, described streaming medium content transmission server 3 can also be in the process of live streaming media file transfer to network player, adjust in real time the sending probability of key frame in the live streaming media file, the I frame that sends in unit interval is increased, thereby satisfy the solution code requirement of decoder as far as possible.
Preferably, described signal acquisition module 11 can for each programme signal source, gather multichannel primary flow media signal simultaneously.Every road signal is the picture of a lens shooting, has namely accessed the picture of a plurality of angle shots for same broadcast time.For example, in certain singer's concert video, in the process that this singer is singing, having multiple cameras takes from a plurality of angles simultaneously, so just gathered multi-channel video signal, be transferred to simultaneously encoder 12, encoder 12 is encoded to every road signal respectively.Network player receives several signals simultaneously, and the road signal of giving tacit consent to is broadcasted, and simultaneously all the other several signals is carried out buffer memory.When the user wishes to see the picture of other angle, can select the cutaway picture.
Preferably, described encoder 12 can be the multiplex coding device, to each concurrent startup multiplex coding in programme signal source, and the corresponding a kind of code check of every road coding.Wherein, the data bits that when code check is exactly transfer of data, the unit interval transmits, code check also is code stream (Data Rate).Like this, same programme signal source just has various code rate to select for the user, and the user can be in the situation that the low code check of less selections of network bandwidth resources, and in the situation that the high code check of bandwidth resources abundance selection, realize the switching of multi code Rate of Chinese character, thereby guarantee the fluency of video playback.And if same programme signal source has gathered multiple signals, encoder 12 can be to every road signal concurrent startup multi code Rate of Chinese character coding all.
Preferably, in order to reduce the number of times of reading and writing data, described Communications service module 13 is distributed to the Streaming Media signal with a plurality of network transmission package at every turn and includes server 2; And described streaming medium content transmission server 3 is included server 2 from the Streaming Media signal and is obtained the live streaming media file with the form of network transmission package, and once obtains a plurality of network transmission package.Transfer of data on network reads the packet of 64K according to conventional TCP/IP agreement mostly at every turn at present.But the present embodiment has defined the communication protocol of oneself, this agreement at every turn to the storage data read-write all greater than 64K.Like this, can reduce the reading and writing data number of times, reduce the expense of whole system and network.
Preferably, described Streaming Media signals collecting server 1 can also comprise:
