Referring to Figure 2, specific steps may include:

210. The global server receives a message from the streaming media server cluster that carries the historical on-demand program information of the first terminal, and saves the historical on-demand program information of the first terminal.

In an application scenario, the streaming media server cluster may generate a historical on-demand program information of the terminal after the terminal stops to order the program, and report the information to the global server, which may be reported to the global server or the terminal. Reported to the global server when indicated. The historical on-demand program information of the terminal can be marked by the identifier of the terminal. The historical on-demand program information of the terminal may include the program identifier and the playback breakpoint information corresponding to the program of the historical on-demand of the terminal, and may further include the identification information of the terminal and other information, wherein the program identifier may be the content identifier and name of the program. Identification or other identification; the playback breakpoint information of the program may refer to a time position or a data position where the playback stops, wherein the time position may be a relative time between the non-live broadcast program playback stop time and the start time, or an absolute time when the live program stops playing. .

The streaming media server cluster may carry the historical on-demand program information of the first terminal in a certain message to the global server; the global server may receive the message, and correspondingly store the historical on-demand program information of the first terminal.

In an actual application, the global server may associate the identifiers of all terminals belonging to the same user, for example, the terminal account with the user identifier of the user, such as a user account, and specifically identify all users of the same user by using the data table. The identifier is associated with the record, and the global server can find the user identifier of the user to which the terminal belongs according to the identifier of the terminal, and further can find the historical on-demand program information of all the terminals of the user according to the user identifier, and can also find the user. Some other information about the terminal.

The global server may maintain a historical on-demand program information table for each user, and a record of the historical on-demand program information of a certain terminal recorded in each user's historical on-demand program information table may include: a program for recording a program identification such as a content identification An identification field, a breakpoint field for playing breakpoint information of the program, and a terminal identification field for recording an identification of the terminal on which the program is to be broadcasted, and may further include for recording the terminal type such as a mobile terminal, an internet terminal, or a digital television The terminal type field of the terminal and the field for recording other information, and the global server can find the historical on-demand program information table corresponding to the user by using the user identifier. Of course, the global server can also maintain only one pair. The program information table should be on-demand of a plurality of users, and a record of the historical on-demand program information table corresponding to the plurality of users may include the above-mentioned various fields (such as a program identification field, a breakpoint field, a terminal identification field, a terminal type field, etc.). In addition, a user identification field for recording the user identification may also be included. The global server may add a corresponding record in the historical on-demand program information table according to the historical on-demand program information of the terminal reported by the streaming media server cluster.

Further, the global server may delete the aging record in the historical on-demand program information table periodically or according to the indication, wherein the aging record may indicate that the storage time of the record has exceeded the set storage time threshold, such as 30 days. , 100 days or other values, etc.

The global server receives the first message that is sent by the portal server to obtain the program information, where the first message carries the identifier of the second terminal.

In an application scenario, when the second terminal needs to order the program, the second terminal may request the portal server to acquire the program information, and the portal server may request the global server to obtain the program information of the on-demand program and belong to the second terminal. Historically on-demand program information and the like for at least one other terminal of the same user. The first message may also carry the type indication of the second terminal. In addition, if the identifier of the terminal is not carried in the first message, it may indicate that the portal server is to obtain program information of the on-demand program, and does not need to obtain historical on-demand program information. .

In an actual application, the global server may maintain a program information table, and a record of the program information recorded in the program information table may include: a field for recording the program identification, a field for linking information of the program, and for recording The field of the program profile may of course include fields for recording other information of the program, and the like. The program identifier may be a content identifier. In addition, it should be noted that the same program may have different link information corresponding to different streaming media servers. Therefore, a program may have multiple pieces of link information. Further, the global server may also update the program information table in time according to the change of the current on-demand program to ensure the validity of the program information recorded in the program information table.

In particular, if some programs can only be requested by a specific type of terminal, a record in the program information table may further include a field for recording the type of the audible terminal, and if the message requesting the program information carries the type indication of the terminal The global server may filter the program information of the terminal-on-demand program of the type from the program information table according to the type indication to improve the validity of the program information fed back to the portal server. 230. The global server searches for historical on-demand program information of at least one terminal associated with the user identifier of the user to which the second terminal belongs according to the identifier of the second terminal.

Here, if the first terminal and the second terminal belong to the same user, the global server may search for historical on-demand program information of at least one terminal associated with the user identifier of the user to which the second terminal belongs, according to the identifier of the second terminal. The historical on-demand program information of the at least one terminal includes historical on-demand program information of the first terminal previously saved by the global server, or may also include historical on-demand program information of the second terminal previously saved.

240. The global server sends a second message to the portal server, where the second message carries the historical on-demand program information of the at least one terminal that is found.

In an application scenario, the second message may also carry program information of one or more on-demand programs, and the program information may include program profiles, link information, content identifiers, and the like. After receiving the second message, the portal server may generate and send page information to the second terminal, where the page information may include program information that carries the on-demand program in the second message, and at least one terminal of the user to which the second terminal belongs Historical on-demand program information, the historical on-demand program information including historical on-demand program information of the first terminal. After receiving the page information that is fed back by the portal server, the second terminal may use the corresponding streaming media server cluster according to the historical on-demand program information of the first terminal in the historical on-demand program information of the at least one terminal included in the page information. The program of the first terminal history on demand is resumed at the breakpoint. Of course, the second terminal may also select other programs on demand or breakpoint.

It should be noted that the first terminal and the second terminal belonging to the same user may be the same type of terminal, or may be different types of terminals. In the embodiment of the present invention, a scenario in which a different type of terminal belonging to the same user performs a breakpoint resume broadcast, that is, a scenario in which a terminal of a different network performs a breakpoint resume broadcast.

It can be seen from the above that, in this embodiment, the global server saves the historical on-demand program information of the terminal that is reported by the maintenance of the streaming media server cluster, and receives the message that the portal server sends the request to obtain the program information, and the message carries the identifier of the second terminal. The global server searches for the historical on-demand program information of the at least one terminal associated with the user identifier of the user to which the second terminal belongs according to the identifier of the second terminal, and feeds back to the portal server, so that the second terminal can be based on the at least one terminal. Historical on-demand program information of a certain terminal in the on-demand program information, resumes the program of the terminal's historical on-demand broadcast at a breakpoint, and the mechanism can be used to implement audio/video program disconnection between different terminals belonging to the same user. Continue to broadcast.

The method for implementing program breakpoint playback in the embodiment of the present invention is described below in the perspective of a streaming server cluster.

Another embodiment of the method for implementing a multi-terminal breakpoint continuous broadcast program may include: a streaming media server cluster receiving a program-on-demand request from a first terminal, wherein the program-on-demand request carries a program identifier corresponding to a program requested for on-demand Transmitting, to the first terminal, a media stream of the program corresponding to the program identifier; if receiving a program off request from the first terminal that carries the program identifier, stopping to push the media stream of the program to the first terminal, and recording Playing the breakpoint information of the program; sending a message carrying the historical on-demand program information of the first terminal to the global server, where the historical on-demand program information of the first terminal includes the program identifier corresponding to the program and the playback breakpoint information.

Referring to Figure 3, specific steps may include:

310. The streaming media server cluster receives a program-on-demand request from the first terminal, where the program-on-demand request carries a program identifier corresponding to the program requested for the on-demand.

In an actual application, the program-on-demand request sent by the first terminal may further carry the identifier information of the first terminal and other information.

320. The streaming media server cluster pushes the media stream of the program corresponding to the program identifier to the first terminal. In an actual application, the streaming media server cluster may first authenticate the first terminal, and the authentication may be performed by the access server entity in the streaming media server cluster, and after the authentication is passed, the program identifier corresponding to the first terminal is pushed. The media stream of the program, which can be performed by a streaming media server entity in the cluster of streaming media servers. In particular, for some program-on-demand services that do not require authentication, the streaming server cluster may not authenticate the first terminal, but may directly push the media stream of the program corresponding to the program identifier to the first terminal.

In an application scenario, if the received program-on-demand request further carries the playback breakpoint information of the program requesting the on-demand program, the streaming media server cluster may push the program corresponding to the program identifier to the first terminal to start at the foregoing The media stream of the breakpoint is played to implement the breakpoint playback of the first terminal. If the program-on-demand request sent by the first terminal can also carry a token, which may be obtained by another terminal that has previously requested the program, the streaming media server cluster may pass the token authentication for the first terminal by default.

330. If receiving a program off request from the first terminal that carries the program identifier, the streaming server cluster stops pushing the media stream of the program to the first terminal, and records the broadcast of the program. Break point information.

340. The streaming media server cluster sends a message carrying the historical on-demand program information of the first terminal to the global server, where the historical on-demand program information of the first terminal includes the program identifier corresponding to the program and the playback breakpoint information.

In an application scenario, the streaming server cluster may generate a historical on-demand program information of the terminal after the first terminal stops the on-demand program, and report the information to the global server, which may be reported to the global server or When the terminal indicates it, it is reported to the global server. The historical on-demand program information of the terminal can be marked with the identity of the first terminal. The historical on-demand program information of the first terminal may include the program identifier and the playback breakpoint information corresponding to the program of the first terminal history on-demand, and may of course include the identification information of the first terminal and other information, wherein the program identifier may be a program The content identifier, the name identifier, or other identifiers; the playback breakpoint information of the program may refer to a time position or a data location where the playback stops, wherein the time location may be a relative time between the non-live broadcast program playback stop time and the start time, or the live broadcast program stops. Absolute time during playback.

After receiving the message carrying the historical on-demand program information of the first terminal, the global server may correspondingly save the historical on-demand program information of the first terminal.

The global server may maintain a historical on-demand program information table for each user, and a record of the historical on-demand program information of a certain terminal recorded in each user's historical on-demand program information table may include: a program for recording a program identification such as a content identification An identification field, a breakpoint field for playing breakpoint information of the program, and a terminal identification field for recording an identification of the terminal on which the program is to be broadcasted, and may further include for recording the terminal type such as a mobile terminal, an internet terminal, or a digital television The terminal type field of the terminal and the field for recording other information, and the global server can find the historical on-demand program information table corresponding to the user by using the user identifier. Of course, the global server may also maintain only one historical on-demand program information table corresponding to multiple users, and the historical on-demand program information table corresponding to multiple users In addition to the above various fields (program identification field, breakpoint field, terminal identification field, terminal type field, etc.), a record may also include a user identification field for recording the user identification. Here, the global server may add a corresponding record in the historical on-demand program information table according to the message of the historical information of the first terminal of the first terminal reported by the streaming server cluster.

Further, when the global server receives the message for requesting the program information sent by the portal server, if the message carries the identifier of the second terminal, the global server searches for the user identifier of the user to which the second terminal belongs according to the identifier of the second terminal. The historical on-demand program information of the associated at least one terminal; where, if the first terminal and the second terminal belong to the same user, the global server may search for the user identifier of the user to which the second terminal belongs according to the identifier of the second terminal. The historical on-demand program information of the at least one terminal, of course, the historical on-demand program information of the at least one terminal includes the historical on-demand program information of the first terminal previously saved by the global server, or may also include the historical on-demand of the previously saved second terminal. Program information. The global server may send the program information carrying the program information of the on-demand program and the searched historical on-demand program information of the at least one terminal to the portal server; after receiving the message, the portal server may generate and send the message to the second terminal. The page information may include program information and historical on-demand program information of the at least one terminal, where the historical on-demand program information includes historical on-demand program information of the first terminal. After receiving the page information that is fed back by the portal server, the second terminal may use the historical streaming media program information of the first terminal in the historical on-demand program information of the at least one terminal included in the page information to pass the corresponding streaming media server cluster. The breakpoint continues to broadcast the program of the first terminal history on demand, and the second terminal may also select other programs on demand or breakpoints, and so on.

It can be seen that, in the embodiment, the streaming media server cluster records the playback breakpoint information of the program when the terminal stops playing a certain program; and displays the program information of the terminal of the terminal reported to the global server, including the program identifier and the program corresponding to the program. Breakpoint information, and the global server can save the historical on-demand program information of the terminal reported by the cluster of the streaming media server, so that other terminals can obtain historical on-demand program information of a terminal from the global server, and can resume the broadcast of the terminal history according to the breakpoint. On-demand program, this mechanism can be used to implement breakpoint playback of audio/video programs between different terminals belonging to the same user.

In order to facilitate a better understanding of the technical solution of the present invention, the following is a specific application scenario in which the mobile terminal B belonging to the same user resumes broadcasting the program of the historical order of the digital television terminal A as an example. The technical solution of the embodiment is described in more detail.

Referring to FIG. 4, another embodiment of a method for implementing a multi-terminal breakpoint continuous broadcast program according to an embodiment of the present invention may include:

401. Digital TV terminal A obtains a page from the portal server P1.

402. The portal server P1 sends a message msl requesting to acquire program information to the global server. In an actual application, the message ms1 may carry a type indication corresponding to the digital television terminal A. Of course, the type indication indicates that the type of the device is a digital television terminal.

403. The global server receives the message msl, and obtains program information that the digital television terminal can order the program according to the type carried by the message msl; and sends the message msl-2 carrying the acquired program information to the portal server P1.

In an actual application, the global server may maintain a program information table, and a record of the program information recorded in the program information table may include: a field for recording the program identification, a field for linking information of the program, and for recording The field of the program profile may of course include fields for recording other information of the program, and the like. The program identifier may be a content identifier. In addition, it should be noted that since the same program corresponds to different streaming media server corresponding link information may be different, therefore, a program may have multiple pieces of link information.

In particular, in the case where there are certain programs that can only be called by a specific type of terminal, a record in the program information table may further include a field for recording the type of the audible terminal, and the message requesting to acquire the program information carries the terminal. When the type indicates, the global server may filter the program information of the terminal-on-demand program of the type from the program information table according to the type indication to improve the validity of the program information fed back to the portal server.

Further, the global server may further update the program information table according to the current situation of the on-demand program to ensure the validity of the program information recorded in the program information table.

404. The portal server P1 receives the message msl-2, generates a page containing program information fed back by the global server, and sends the page to the digital television terminal A.

405. The digital television terminal A views the program selected to be on-demand in the page returned by the portal server P1, and sends a program-on-demand request to the access server S1-1, where the program-on-demand request carries the program identifier corresponding to the program requested for on-demand.

406. The access server S1-1 may first authenticate the digital television terminal A, and if the authentication passes, The digital television terminal A is assigned a token, a frequency point and a video server, and the video server S1-2 is notified to push the media stream of the program corresponding to the program identification to the digital television terminal A.

407. The video server S1-2 pushes the media stream of the program corresponding to the program identifier to the digital television terminal A.

408. After playing for a period of time, if the playback needs to be stopped, the digital television terminal A accesses the server.

S1-1 sends a program off request.

409. The access server S 1 -1 notifies the video server that S 1 - 2 stops pushing the media stream of the program corresponding to the program identifier to the digital television terminal A, and records the playback breakpoint information of the program.

410. The access server S1-1 sends a message to the global server, ms2, and the message ms2 carries the historical on-demand program information of the digital television terminal A.
