Media controller can call the concerned control command on media server and media player to media content Transmission and displaying are controlled.Media controller can also obtain the status information of media player and media player is played Media content status information.It should be noted that media controller, which can be one, is different from media server and media The physical equipment of player can also collectively constitute a physical equipment with media server or media player.

The adaptive media content of each media renderer plays has certain code rate.Media controller is available to be arrived The code rate of the adaptive media content of each media renderer plays.

If the broadcasting code rate of step 102, M1 adaptive code streaming medium content is lower than corresponding first code rate thresholding Value, and M1 < N, then media controller adjusts the broadcasting code rate of the adaptive code streaming medium content of K media renderer plays, M1 ≤K≤N。

Wherein, the first code rate threshold value corresponding to the adaptive code streaming medium content of each media renderer plays can be with It is the adaptive code streaming medium content of the device capability information according to each media player and each media renderer plays What description information obtained.First code rate threshold value can be media player and be obtained according to device capability information and description information 's.

The device capability information of media player may include the screen size of the media player, resolution sizes, can Audio/video encoding/decoding format of support etc..It may include that the media content is corresponding in the description information of adaptive code streaming medium content Multiple code rate informations.The file of multiple and different code rates of the same media content is stored on media server, in media It include the information of these code rates in the description information of appearance.When the same media content plays in different media players, by It is different in the capacity of equipment of each media player, so in order to reach identical effect, required code rate may be different；Example Such as：The same film can reach preferable result of broadcast when playing on mobile phone, using relatively low code rate, and in electricity When playing depending on, need to can be only achieved preferable result of broadcast using relatively high code rate.That is, in the same media When appearance plays in different media players, in order to reach identical effect, required code rate may be different.

It can be according to the device capability information of each media player and the adaptive code stream of each media renderer plays The description information of media content obtains the first code rate corresponding to the adaptive code streaming medium content of each media renderer plays Threshold value.Such as：Player A1 plays adaptive code streaming medium content a1, according to the device capability information of player A1 and adaptive The description information for answering code stream media content a1 obtains the first code rate door when player A1 plays adaptive code streaming medium content a1 Limit value.First code rate threshold value of the different adaptive code streaming medium content of the same media renderer plays can be different；Example Such as：Multiple code rate informations that adaptive code streaming medium content a1 and a2 has are different, the code rate of media content a1 have 2.2Mbps, 1.6Mbps, 1.2Mbps, 800Kbps, 400Kbps, 200Kbps, the code rate of media content a2 have 1.1Mbps, 800Kbps, 500Kbps,200Kbps；If needing the code rate of media content to be greater than or wait to reach preferable effect on player A1 In 1.2Mbps, then, when player A1 plays media content a1, the first code rate threshold value is 1.2Mbps, but for matchmaker Holding a2 in vivo, maximum code rate only has 1.1Mbps, so when player A1 plays media content a2, the first code rate threshold value For 1.1Mbps.First code rate threshold value of the same adaptive code streaming medium content of different media renderer plays can also be with It is different；Such as：Since the screen size of mobile phone and TV, resolution sizes are different, so the same adaptive code Streaming Media Respectively when playing on mobile phone and TV, the first code rate threshold value is different content.

When the adaptive code streaming medium content that media controller gets part of media player plays is corresponding lower than respectively The first code rate threshold value when, the adaptive code streaming medium content of media controller adjustment member or total medium player plays Broadcasting code rate.

The mode that media controller adjusts the broadcasting code rate of the adaptive code streaming medium content of media renderer plays can be with Including：(1) media controller is according to the total bandwidth and each adaptive code stream matchmaker for being used to play N number of adaptive code streaming medium content The description information held in vivo is that the adaptive code streaming medium content of each media renderer plays distributes corresponding broadcasting code rate, And code rate adjustment order is sent to media server, so that it is assigned that media server, which sends code rate to each media player, Transmission code rate adaptive code streaming medium content；Alternatively, the adjustable played adaptive code stream matchmaker of (2) media controller The service quality rating held in vivo, after the service quality rating of some adaptive code streaming medium content is raised, according to adaptive The characteristic of code stream itself is answered, the code rate of the adaptive code streaming medium content can be enhanced.

Fig. 2 is the flow chart that the another kind of the embodiment of the present invention plays the method for multiple adaptive code streaming medium contents, On the basis of embodiment illustrated in fig. 1, as shown in Fig. 2, this method includes：

Step 201, media controller obtain the adaptive code of each media renderer plays in N number of media player respectively The broadcasting code rate of streaming medium content, N >=2.

The number of media player in the network media system in broadcast state is N, i.e., in the network media system Including N number of media player for being playing self-adaption code rate media content.

Media controller get the adaptive code streaming medium content of each media renderer plays broadcasting code rate it Afterwards, if the broadcasting code rate of M1 adaptive code streaming medium content is lower than corresponding first code rate threshold value, and M1 < N, then The broadcasting code rate of the adaptive code streaming medium content of the adjustable K media renderer plays of media controller, M1≤K≤N；Under Process in face of adjustment illustrates.

If the broadcasting code rate of step 202, M1 adaptive code streaming medium content is lower than corresponding first code rate thresholding Value, and M1 < N, then media controller is according to the total bandwidth for being used to play N number of adaptive code streaming medium content and each adaptive The description information of code stream media content is that the adaptive code streaming medium content of K media renderer plays distributes corresponding broadcasting Code rate.

Wherein, the first code rate threshold value corresponding to the adaptive code streaming medium content of each media renderer plays is root According to the description of the adaptive code streaming medium content of the device capability information and each media renderer plays of each media player What information obtained.Wherein, when the broadcasting code rate of some media renderer plays some adaptive code streaming medium content is greater than or waits When corresponding first code rate threshold value, the result of broadcast of the media renderer plays adaptive code streaming medium content is preferable. Such as：Adaptive code streaming medium content a1 is corresponding with the file that code rate is respectively f0, f1, f2, f3, wherein f0, f1, f2, f3 Code rate value successively increases；When player A1 plays adaptive code streaming medium content a1, to reach preferable effect, adaptive code The minimum f1 of the code rate of streaming medium content a1, i.e., when player A1 plays adaptive code streaming medium content a1, the first code rate door Limit value is f1；When player A2 plays adaptive code streaming medium content a1, to reach preferable effect, adaptive code Streaming Media The minimum f2 of the code rate of content a1, i.e., when player A2 plays adaptive code streaming medium content a1, the first code rate threshold value is f2；Because the capacity of equipment of player A1 and player A2 is different, above-mentioned two first code rate threshold value is different.

It should be noted that the first code rate threshold value can be obtained in real time by media controller, can also be stored in advance In record sheet, table look-up to obtain by media controller.

The adaptive code streaming medium content for getting part of media player plays broadcasting code rate lower than corresponding the When one code rate threshold value, media controller can be according to total bandwidth for playing adaptive code streaming medium content and each adaptive The description information of code stream media content is answered, distributes corresponding broadcast for the adaptive code streaming medium content of each media renderer plays Code rate is put, so that the adaptive code streaming medium content of each media renderer plays can reach preferable result of broadcast.

In a particular embodiment, media controller is according to total band for playing N number of adaptive code streaming medium content The description information of wide and each adaptive code streaming medium content is the adaptive code streaming medium content of each media renderer plays When distributing corresponding broadcasting code rate, code rate is played according to following regular one and two distribution of rule：

The sum of the transmission code rate of adaptive code streaming medium content of N number of media renderer plays after regulation one, distribution is small In or equal to the total bandwidth for being used to play N number of adaptive code streaming medium content.

In a network media system, the total bandwidth for playing adaptive code streaming medium content is certain, so point The sum of transmission code rate of adaptive code streaming medium content with rear each media renderer plays cannot be greater than above-mentioned total bandwidth.

If the sum of the first code rate threshold value of adaptive code streaming medium content of regulation two, N number of media renderer plays is small In or equal to described for playing the total bandwidth of adaptive code streaming medium content, then N number of media renderer plays after distributing The broadcasting code rate of adaptive code streaming medium content is respectively greater than or is equal to corresponding first code rate threshold value；If N number of media are broadcast The sum of the first code rate threshold value of adaptive code streaming medium content for putting device broadcasting is greater than described described N number of adaptive for playing The total bandwidth of code stream media content, then the broadcasting code of the adaptive code streaming medium content of N number of media renderer plays after distributing Rate is respectively greater than or is equal to corresponding second code rate threshold value.

Wherein, the second code rate threshold value corresponding to the adaptive code streaming medium content of each media renderer plays is root It is obtained according to the device capability information of each media player and the description information of each adaptive code streaming medium content；Each matchmaker First code rate threshold value corresponding to the adaptive code streaming medium content of body player plays is greater than the second code rate threshold value.

It should be noted that the first code rate threshold value refers to：In order to reach preferable result of broadcast, media player is broadcast Code rate needed for the adaptive code streaming medium content put；Second code rate threshold value refers to：When the first code rate threshold value can not expire When sufficient, in order to achieve the effect that the result of broadcast (poorer than the first code rate threshold value) that can be watched, media renderer plays from Code rate needed for adapting to code stream media content.

Further, preferable in order to reach when there are many allocation plan under the premise of meeting rule one and rule two Effect, can choose the maximum one kind of the sum of transmission code rate of adaptive code streaming medium content of N number of media renderer plays Allocation plan.

Step 203, media controller are according to the adaptive code streaming medium content distribution for each media renderer plays Code rate is played, code rate adjustment order is sent to media server, so that the media server is to each media player Send the adaptive code streaming medium content that code rate is assigned transmission code rate.

After step 204, media server receive the code rate adjustment order of media controller transmission, to each media play Device sends the adaptive code streaming medium content that code rate is the transmission code rate distributed by media controller.

The embodiment of the present invention, the adaptive code streaming medium content of the available each media renderer plays of media controller Broadcasting code rate, when the adaptive code streaming medium content for having part of media player plays broadcasting code rate be lower than corresponding code rate When threshold value, the broadcasting code rate of the adaptive code streaming medium content of the adjustable multiple media renderer plays of media controller； Specifically, media controller can be each media player according to total bandwidth, the description information of adaptive code streaming medium content The adaptive code streaming medium content distribution of broadcasting is suitable to play code rate, so as to realize fair broadcasting, improves user experience.

Another adjustment mode is illustrated below by Fig. 3 the embodiment described.

Fig. 3 is the flow chart that the another kind of the embodiment of the present invention plays the method for multiple adaptive code streaming medium contents, On the basis of embodiment illustrated in fig. 1, as shown in figure 3, this method includes：

Step 301, media controller obtain the adaptive code of each media renderer plays in N number of media player respectively The broadcasting code rate of streaming medium content, N >=2；If the broadcasting code rate of the M1 adaptive code streaming medium contents is corresponding lower than respectively The first code rate threshold value, and M1 < N thens follow the steps 302；If the broadcasting code rate of the M1 adaptive code streaming medium contents Lower than corresponding first code rate threshold value, and M1=N, then follow the steps 306.

Media controller get the adaptive code streaming medium content of each media renderer plays broadcasting code rate it Afterwards, if the broadcasting code rate of M1 adaptive code streaming medium content is lower than corresponding first code rate threshold value, and M1≤N, then media The broadcasting code rate of the adaptive code streaming medium content of the adjustable K media renderer plays of controller, K≤N；Below to adjustment Process illustrate.

Step 302, media controller request media server improve the M1 broadcasting code rate and are lower than corresponding first yard The service quality rating of the corresponding data message of adaptive code streaming medium content of rate threshold value, so that the M1 broadcasting code Rate is preferentially sent to correspondence lower than the corresponding data message of adaptive code streaming medium content of corresponding first code rate threshold value Media player in, and the broadcasting code rate of the K adaptive code streaming medium content is adjusted.

When media server data message corresponding to multiple media players transmission adaptive code streaming medium content, matchmaker Body server can be sent datagram by gateway to media player；Gateway is forwarding datagram to multiple media players Wen Shi can preferentially forward service quality (Quality of Service, QoS) high data message of grade.As a result, when media control Device request media server processed improves the adaptive code streaming medium content of some media player (such as media player A) broadcasting After the QoS grade of corresponding data message, gateway can preferentially forward the data message, and be sent to other media players Data message will cause a degree of obstruction, other media players is caused to think that network bandwidth is inadequate, according to DASH technology Strategy, other media players from trend media server request compared with low bit- rate data message, the network bandwidth saved out The data message that application high code rate can be gone for media player A, so that multiple adaptive code streaming medium contents are broadcast Putting code rate can be adjusted.

N=2 in a certain specific embodiment, in the present embodiment.

It should be noted that improving the QoS grade of the corresponding data message of the M1 adaptive code streaming medium content, phase When in the QoS grade for reducing the corresponding data message of other adaptive code streaming medium contents.As a result, in a specific embodiment, It can be improved in step 302 by the QoS grade of the corresponding data message of the other adaptive code streaming medium contents of reduction to realize The QoS grade of the corresponding data message of the M1 adaptive code streaming medium content.

It after step 302, can also include step 303.

Step 303, media controller obtain the broadcasting code rate of each adaptive code streaming medium content；If each adaptive code The broadcasting code rate of streaming medium content is greater than or equal to corresponding first code rate threshold value, thens follow the steps 304；If N number of adaptive The sum of corresponding first code rate threshold value of code stream media content is greater than total band for playing N number of adaptive code streaming medium content Width thens follow the steps 305.

Step 304, media controller request media server restore the adaptive code stream matchmaker for being enhanced service quality rating Hold the service quality rating of corresponding data message in vivo, terminates, alternatively, repeating step 301.

After the QoS grade of media controller adjustment data message, if the broadcasting of each adaptive code streaming medium content Code rate is all larger than or is equal to corresponding first code rate threshold value, then can stop adjusting；After the QoS grade of adjustment is resumed, The QoS grade of all data messages is identical, and gateway is according to received sequencing forwarding data packets at this time, thus each adaptive Answering the broadcasting code rate of code stream media content will not continue to be adjusted.

Step 305, media controller the adaptive code streaming medium content for not being enhanced service quality rating broadcasting code When rate adjustment to equal than corresponding first code rate threshold value, the media server recovery is requested to be enhanced service quality rating The service quality rating of the corresponding data message of adaptive code streaming medium content.

If the sum of corresponding first code rate threshold value of N number of adaptive code streaming medium content is greater than N number of adaptive for playing The total bandwidth of code stream media content, then the broadcasting code rate that can not be adjusted to each adaptive code streaming medium content are all larger than or are equal to Corresponding first code rate threshold value.In this case, when the broadcasting code rate of the good adaptive code streaming medium content of script result of broadcast When being adjusted to corresponding first code rate threshold value, stop adjustment.Wherein, it is not enhanced the adaptive code Streaming Media of QoS grade Content is the good adaptive code streaming medium content of script result of broadcast, that is, the broadcasting code rate before adjustment is greater than or is equal to The adaptive code streaming medium content of corresponding first code rate threshold value.

After step 305, can terminate, alternatively, repeating step 301.

It is respectively right that step 306, media controller judge whether the broadcasting code rate of each adaptive code streaming medium content is lower than The the second code rate threshold value answered；If the broadcasting code rate of M2 adaptive code streaming medium content is lower than corresponding second code rate thresholding Value, and M2 < N, then follow the steps 307.Wherein, M1 and M2 may be the same or different.In a certain specific embodiment, N=2 in the present embodiment.

Step 307, media controller request media server improve the M2 broadcasting code rate and are lower than corresponding second code The service quality rating of the corresponding data message of adaptive code streaming medium content of rate threshold value, so that the broadcasting code rate is low Corresponding matchmaker is preferentially sent in the corresponding data message of adaptive code streaming medium content of corresponding second code rate threshold value In body player, and the broadcasting code rate of the K adaptive code streaming medium content is adjusted.

Step 308, media controller obtain the broadcasting code rate of each adaptive code streaming medium content；If each described adaptive It answers the broadcasting code rate of code stream media content to be greater than or equal to corresponding second code rate threshold value, thens follow the steps 309；If N number of institute The sum of corresponding second code rate threshold value of adaptive code streaming medium content is stated greater than described for playing N number of adaptive code stream The total bandwidth of media content, thens follow the steps 310.

Step 309, media controller request the media server to restore the adaptive code for being enhanced service quality rating The service quality rating of the corresponding data message of streaming medium content terminates, alternatively, repeating step 306.

Step 310, media controller the adaptive code streaming medium content for not being enhanced service quality rating broadcasting code When rate adjustment to equal than corresponding second code rate threshold value, the media server recovery is requested to be enhanced service quality rating The service quality rating of the corresponding data message of adaptive code streaming medium content.

It should be noted that the adjustment process class of the adjustment process of step 307- step 310 and step 302- step 305 Seemingly, difference is as the code rate threshold value difference for judging benchmark.

The embodiment of the present invention, the adaptive code streaming medium content of the available each media renderer plays of media controller Broadcasting code rate, when the adaptive code streaming medium content for having part or all of media renderer plays broadcasting code rate lower than correspond to Code rate threshold value when, the broadcasting of the adaptive code streaming medium content of the adjustable multiple media renderer plays of media controller Code rate；Specifically, media controller can by the QoS grade of the data message of partial adjustment adaptive code streaming medium content, It adjusts the broadcasting code rate of adaptive code streaming medium content, so as to realize fair broadcasting, improves user experience.

Below with reference to Fig. 4 and Fig. 5, the embodiment of the present invention is illustrated.

Fig. 4 is the flow chart that the another kind of the embodiment of the present invention plays the method for multiple adaptive code streaming medium contents, this Embodiment is illustrated by taking N=2 as an example, as shown in figure 4, this method includes：

Step 401, digital media player DMR1 (Digital Media Renderer) are to digital media server (Digital Media Server, DMS) obtains the media data of adaptive code stream media content Media#1, and on DMR1 It plays.

DMS, digital media controller DMC, 2 digital media players DMR1 and DMR2 belong to same in network system In one subnet, these equipment can interconnect, and all data messages that above equipment is sent and received require By gateway forwards, i.e. pass through gateway data message transmission between DMS and DMR.

DMR1 establishes media transmission session request to DMS initiation, and receive DMS issue DMR1 about to be played from Display advertising description corresponding to adaptation code stream media content Media#1 (Media Presentation Description, MPD) file, MPD file are the media data.After DMR1 receives the MPD file of media content Media#1, according to biography The processing method of system adaptive code Streaming Media, assesses current wideband condition, selects to be suitble to current network in MPD file Media file corresponding to the code rate of situation transmission, and request the code rate to correspond to the fragment data of media file to DMS, DMS will Requested fragment data is sent to DMR1, and plays on DMR1.The fragment data is equivalent in above-described embodiment Data message；MPD file is equivalent to the media content description information in above-described embodiment.

Step 402, DMR2 obtain the media data of adaptive code stream media content Media#2 to DMS, and broadcast on DMR2 It puts.

Step 402 is similar with the process of step 401, and does not limit the sequencing of step 401 and step 402.

Step 403, digital media controller (Digital Media Controller, DMC) are issued to DMS and are requested, from DMS obtains the MPD file of media content Media#1 and the MPD file of Media#2 respectively.

Step 404, DMR1 and DMR2 are according to the device capability information of respective player and the media content played The description information of Media#1 and Media#2 calculates the code rate threshold value of respective media renderer plays media content, and will The code rate threshold value reports to DMC.

The present embodiment does not limit the sequencing of step 403 and step 404 yet.

Wherein, device capability information may include the screen resolution information of player.If the adaptive code stream played The code rate of media content is at or above corresponding code rate threshold value, then illustrates that adaptive code streaming medium content is suitble in correspondence Player on play, and preferable visual experience effect can be obtained.Such as：Network system Zhong Youliangtai Digital Media is broadcast Device DMR1 and DMR2 are put, plays adaptive code streaming medium content movie A and movie K respectively.Wherein, DMR1 is an intelligence Mobile phone, screen resolution are that 800 × 600, DMR2 is a high definition television, and screen resolution is 1920 × 1080；movie The description information of A be movie A provided by code stream fragment code rate have 2.2Mbps, 1.6Mbps, 1.2Mbps, 800Kbps, 400Kbps, 200Kbps, the description information of movie K be code stream fragment provided by movie K code rate have 1.8Mbps, 1.5Mbps,1.1Mbps,800Kbps,500Kbps,200Kbps.According to the screen of two media players of DMR1 and DMR2 point Resolution, the media content description information of two adaptive code streaming medium content movie A and movie K, can calculate DMR1 Code rate threshold value when playing movie A is 800Kbps, code rate threshold value 1.5Mbps of the DMR2 when playing movie K, And these threshold values are reported to DMC.Specifically, can be according to code rates different in description information and media content screen resolution Corresponding relationship, obtain code rate threshold value.

Code rate threshold value in the present embodiment is equivalent to the first code rate threshold value in above-described embodiment.

Step 405, DMC obtain the broadcasting code rate of the media content played in DMR1 and DMR2, and judge DMR1 and DMR2 Whether the broadcasting code rate of the media content of middle broadcasting is less than corresponding code rate threshold value, if the media played in some player The broadcasting code rate of content is less than corresponding code rate threshold value, thens follow the steps 406.

Step 406, DMC are calculated according to total bandwidth, the description information of media content and code rate threshold value for broadcasting To the optimal allocation code rate of the played adaptive code streaming medium content of two media players.

The concrete operation step of calculating can be：DMC is played in media respectively according to two media player DMR1 and DMR2 Hold code rate threshold value when movie A and movie K, movie A is extracted from the MPD file of media content movieA in DMR1 Code rate near the code rate threshold value of middle broadcasting extracts movie K in DMR2 from the MPD file of media content movie K Code rate near the code rate threshold value of broadcasting carries out permutation and combination, constitutes all possible schemes.Then according to original listed below It is then screened, to calculate best code rate allocation plan.Specific screening principle is as follows：

(1) the sum of the code rate of the adaptive code streaming medium content of two media renderer plays, which is not greater than, after adjusting is used for The total bandwidth of broadcasting；

(2) after the condition that meets (1), the code rate of the adaptive code streaming medium content of two media renderer plays after adjustment More than or equal to the code rate threshold value of corresponding player；

(3) it after the condition that meets (1) and (2), takes after adjusting in the adaptive code Streaming Media of two media renderer plays The highest component formula case of the sum of code rate of appearance.

Such as：In the present embodiment, the code rate of selected movie A is 1.2Mbps and 800Kbps, selected The code rate of movie K is 1.8Mbps and 1.5Mbps.After by permutation and combination and meeting condition (1) and (2), there are following 3 kinds Allocation plan：

<1>movie A：1.2Mbps；movie K：1.5Mbps；

<2>movie A：800Kbps；movie K：1.8Mbps；

<3>movie A：800Kbps；movie K：1.5Mbps；

Then according to condition (3), obtaining optimal allocation plan is movie A：1.2Mbps, movie K： 1.5Mbps。

Step 407, the optimum distributing scheme calculated according to DMC, DMC is issued to DMS and is requested, so that DMS is according to most Code rate in good allocation plan distributes the code stream fragment of adaptive code streaming medium content to DMR1 and DMR2.

The embodiment of the present invention, each media player can be by the screen resolution informations of player, played adaptive code The description information of streaming medium content and the code rate threshold value of player are reported to DMC, and DMC calculates optimal according to above- mentioned information Data Rate Distribution scheme, and issued and requested to DMS according to the program, request DMS sends optimal code rates point to each media player Media code stream with code rate shown in scheme improves user experience so as to realize fair broadcasting.

Fig. 5 is the flow chart that the another kind of the embodiment of the present invention plays the method for multiple adaptive code streaming medium contents, this Embodiment is illustrated by taking N=2 as an example, as shown in figure 5, this method includes：

Step 501, DMR1 obtain the media data of adaptive code stream media content Media#1 to DMS, and broadcast on DMR1 It puts.

Step 502, DMR2 obtain the media data of adaptive code stream media content Media#2 to DMS, and broadcast on DMR2 It puts.

Step 501 is identical as step 401, the step 402 in embodiment illustrated in fig. 4 as step 502.

Step 503, DMC obtain the device capability information of DMR1.

DMC calls AVT to DMR1：：GetDeviceCapabilities () order, notice DMR1 return to setting for its equipment Standby ability information.DMR1 sends response message according to the request command of MDMC, contains the capacity of equipment of DMR1 in response message Information may include screen size, resolution sizes, supported audio/video encoding/decoding format of equipment etc..

Step 504, DMC obtain the device capability information of DMR2.

Step 504 is similar with step 503, and the present embodiment does not limit the sequencing of step 503 and step 504.

Step 505, DMC obtain the status information of the played media content of DMR1 and DMR2 respectively.

DMC calls AVT to DMR1 and DMR2 respectively：：GetTransportInfo () order, notifies DMR1 and DMR2 to return The status information of played media content in its equipment.DMR1 and DMR2 sends response message, response according to the request command of DMC The current broadcast state information of media Media#1 and Media#2 that DMR1 and DMR2 are played is contained in message, may include The information such as title, media formats, the transmission code rate of played media.

It should be noted that step 505 can be before step 503, it can also be after the step 503.

Step 506, DMR1 and DMR2 are according to the device capability information of respective player, the adaptive code Streaming Media played The description information and broadcast state information of content calculate the of respective media renderer plays adaptive code streaming medium content One code rate threshold value (ideal play code rate) and the second code rate threshold value (code rate of tolerance broadcasting), and by the first code rate door Limit value and the second code rate threshold value report to DMC.

In the present embodiment, it if having two digital media players DMR1 and DMR2 in home network, plays respectively adaptive Answer code stream media content movie A and movie K.Wherein, DMR1 be a smart phone, screen resolution be 800 × 600, DMR2 be a high definition television, and screen resolution is 1920 × 1080；The description information of movie A is movie A institute The code rate of the code stream fragment of offer has 2.2Mbps, 1.6Mbps, 1.2Mbps, 800Kbps, 400Kbps, 200Kbps, movie K Description information be movie K provided by code stream fragment code rate have 1.8Mbps, 1.5Mbps, 1.1Mbps, 800Kbps, 500Kbps,200Kbps.According in the screen resolution of two media players of DMR1 and DMR2, two adaptive code Streaming Medias The media content description information for holding movie A and movie K, calculates DMR1 and DMR2 when playing movie A and movie K The first code rate threshold value be respectively 800Kbps and 1.5Mbps, the second code rate threshold value is respectively 200Kbps and 500Kbps, And the first code rate threshold value and the second code rate threshold value are reported to DMC.

Step 507, DMC are according to first yard of the played adaptive code streaming medium content of the different media players got The status information of rate threshold value, the second code rate threshold value and played media, judges whether the adjustment for needing to carry out code rate；If It needs to adjust, thens follow the steps 508.

Specific deterministic process is referring to Fig. 6, as shown in fig. 6, firstly, DMC obtains played adaptive code streaming medium content Corresponding first code rate threshold value and the second code rate threshold value, and periodically obtain the broadcast state letter of each media content Breath, the broadcasting code rate information including media content.After DMC gets above- mentioned information, can broadcast state information to media with Code rate threshold value is compared, and point situation adjusts the code rate of the adaptive code Streaming Media played on each media player It is whole：

(1) code rate of the media code stream of player plays is above corresponding first code rate threshold value；

(2) code rate of the media code stream of part player plays is lower than corresponding first code rate threshold value；

(3) code rate of the media code stream of player plays is below corresponding first code rate threshold value.

For situation (1), the code rate of the adaptive code streaming medium content of all player plays is above corresponding One code rate threshold value indicates that the media content of all player plays can allow user to obtain ideal visual experience, therefore this Kind situation plays as usual without being adjusted to code stream.For situation (2), there is the adaptive code of part player plays The code rate of streaming medium content is lower than corresponding first code rate threshold value, indicates that the media content of this part player plays cannot allow User obtains ideal visual experience, it is therefore desirable to adjust, those media codes for being lower than its first code rate threshold value are turned up The code rate of stream makes it higher than its corresponding first code rate threshold value.But it can be reduced during adjustment and original be higher than that its is right Those of first code rate threshold value is answered to play the code rate of media code stream, it is possible to make it below corresponding first code rate threshold value. Therefore, the case where code rate of broadcasting media code stream all after being unable to satisfy adjustment is above corresponding first code rate threshold value Under, its code rate is not less than corresponding first yard after should ensure that those original media code stream adjustment higher than its first code rate threshold value Rate threshold value.For situation (3), the adaptive code streaming medium content of all player plays cannot allow user more to be managed The visual experience thought, in this case, DMC check whether that the code rate of the media code stream of player plays is above corresponding Two code rate threshold values, if so, playing as usual；If it is not, those media codes for being lower than corresponding second code rate threshold value are then turned up The code rate of stream, to guarantee that the code rate of media code stream of all broadcastings is above corresponding second code rate threshold value.

In the present embodiment, the code rate for the adaptive code streaming medium content Movie A that media player DMR1 is played at present Code rate for 2.2Mbps, media player DMR2 the adaptive code streaming medium content Movie K played at present is 500Kbps, point It does not make comparisons with the first code rate threshold value of DMR1 and DMR2 and the second code rate threshold value, it can be deduced that this situation belongs to situation (2), the code rate for needing to be turned up the media Movie K that DMR2 is played makes it higher than the first code rate threshold value of DMR2 1.5Mbps, but on condition that the code rate of the media Movie A played on DMR1 after adjustment cannot be decreased below the first of DMR1 Code rate threshold value 800Kbps.

Here is specific adjustment process.
