Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, a system, and a device for playing service content.
Background
IPTV (interactive network television) is a brand-new technology that uses a broadband cable television network, integrates multiple technologies such as internet, multimedia, and communication, and provides multiple interactive services including digital television to home users.
A user can enjoy IPTV service in two ways at home: (1) computer, (2) network set-top box + common television. The method can well adapt to the rapid development trend of the current network and fully and effectively utilize network resources.
IPTV provides various digital media services including tv programs through internet protocols by using the infrastructure of a broadband cable tv network and using a home tv set as a main terminal appliance.
Among mobile multimedia services, the mobile video broadcasting service is a very important service. The mobile video broadcast service is a new type of mobile service for delivering video content to mobile users via a broadcast network, a mobile network and a mobile terminal. This service is also called "mobile tv service".
For the mobile multimedia broadcasting service, due to the diversification of technologies and the difference of external environments, there are various embodiments of the mobile multimedia broadcasting service. In order to mask the inconsistency of user experience brought by different technologies at the level of service provision, a unified provision is required at the service level. In this regard, the OMA (openmobilealance) organization has predominantly established BCAST (broadcast service) service standards. In broadcasting, it includes a conventional one-to-many broadcasting mode and a multicast (multicast) mode, and it is considered that the original digital broadcasting services are connected on the existing network architecture. OMA's BCAST addresses service discovery, electronic programming/service steering, charging, content protection, etc., formulates a specific service engine and ensures that it is independent of the bearer layer.
At present, the function of the terminal to realize the delayed play is mainly to add a buffer function of a media stream in terminal software. The main idea is to structure a corresponding storage area on top of the terminal that can perform the mobile multimedia broadcasting service. Meanwhile, the caching function of the media stream is added in the software. During the playing process, if the user needs to cache or pause the program, at this moment, the media stream received by the playing client is directly cached in the corresponding storage area, and the playing picture of the terminal is directly paused. When the user resumes playing, the corresponding media stream is extracted from the storage area for playing. In the playing process, the player plays the cached content, and the live content is still directly cached in the storage area through the receiving module. Such a process continues until the current playback is stopped.
The above implementation method requires that the terminal can locally cache the received media stream, and at the same time, the terminal needs to correspondingly encode the cached media stream and store the encoded media stream in a corresponding storage area. In addition, it is also necessary to provide a storage space of hardware large enough to support the delayed play function for a long time. Such consideration will place relatively high demands on terminal hardware, particularly on RAM (random access memory) and ROM (read only memory) of the terminal.
Furthermore, for content with digital rights protection, this way of buffering in the storage area is in violation of the digital rights protection principle. Therefore, the service content with copyright protection cannot be played in such a way.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a method for playing service content, which realizes the playing of mobile multimedia service content through the existing network, and enables users to obtain the same user experience and feeling as the playing of local service content when developing multimedia broadcasting service.
The embodiment of the invention combines the broadcast channel and the interactive channel, and realizes the playing of the mobile multimedia broadcast service content through content distribution modes of different approaches. The real-time media stream transmission is realized by utilizing the characteristic of large capacity of the broadcast channel, and the playing of non-real-time/delay content is realized by adopting a mode of combining the broadcast channel and the interactive channel.
In the embodiment of the present invention, the service provider will isolate the terminal from the experience of the network modality, that is, the terminal can only perceive the mobile multimedia broadcasting service being performed, but there is no relevant information perception as to whether the service content is transmitted by using the broadcast channel or the interactive channel.
As shown in fig. 1, a flowchart of a method for playing service content according to an embodiment of the present invention includes:
step S101, obtaining the playing control information of the service content playing control function.
Wherein the playing control information is provided by a service guide, and the playing control information includes one or more of the following: the service content playing control function comprises enabling information of the service content playing control function, address information of a media playing control server of the service content playing control function, function list information of the service content playing control function and broadcast service information related to the service content playing control function.
And step S102, controlling the playing of the service content according to the playing control information.
The controlling the playing of the service content according to the playing control information may specifically be: sending a content playing control request to a media playing control server through an interactive channel, and requesting the media playing control server to control the playing of service content; or,
and accessing the broadcast service information associated with the play control information to a broadcast server to control the play of the service content.
Before controlling the playing of the service content according to the playing control information, whether the service content being played by the terminal provides the playing control function is determined by analyzing the playing information prompted by the service guide, and the playing control function is prompted to the terminal. The prompt message is carried in Service and Content fragments of the Service guide.
In the embodiment of the present invention, the content playing control request carries playing information prompted by the service guide and playing control function information selected by the terminal, and the terminal sends the content playing control request to the media playing control server through the interactive channel according to a format of HTTP (hypertext transfer protocol).
After the media playing control server receives the content playing control request sent by the terminal, the media playing control server can authenticate the terminal according to the content playing control request, and ensure that the terminal has the authority to perform the playing control function requested by the terminal.
In the process of playing the service content by the terminal, the terminal reports the playing condition of the terminal to the media playing control server, so that the media playing control server switches the service content from the on-demand mode of the interactive channel to the on-demand mode of the broadcast channel according to the playing condition of the terminal and the user information.
When a terminal needs to recover the playing function of the service content being played by the terminal, the terminal may adopt one of the following ways:
(1) the terminal submits a playing request to the media playing control server in an HTTP request mode, and receives the service content which is sent by the media playing control server in an HTTP mode and is played by the terminal subsequently.
(2) When a terminal requests a media playing control server to pause playing of service content, the terminal receives the content of the data broadcast according to parameter information of the data broadcast carried by a response message sent by the media playing control server, and caches the received content of the data broadcast in a storage space of the terminal to wait for resuming playing.
(3) When a terminal requests a media playing control server to pause playing of service content, the terminal obtains the service content cached by a cache server through RTSP (Real time streaming protocol), RTP (Real-time transport protocol), RTCP (Real-time transport control protocol) or HTTP, and plays the cached service content.
The playing method of the service content realizes the playing of the mobile multimedia service content through the existing network, and the terminal controls the playing of the service content according to the obtained playing control information. When the user develops the multimedia broadcasting service, the user experience and feeling which are the same with the content of the broadcast local service can be obtained.
As shown in fig. 2, a flowchart of a first embodiment of a method for playing service content according to the present invention is shown, where the first embodiment is an embodiment of a method for playing service content under BCAST service, and the first embodiment mainly solves a situation that a user needs to perform operations such as pause, fast forward, fast rewind, and the like on service content while watching a real-time mobile multimedia broadcast service. In the first embodiment, a broadcast content transmission mode is combined with an interactive channel content mode, and a service guide of an SG (service guide) and information reporting modes of related interactive channels are used for completing related functions. According to the process of service development, the first embodiment specifically includes:
in step S201, the terminal acquires the content and information of the service guide SG, and extracts the service content concerned by the terminal from the content and information of the SG.
The terminal acquires the content and information of the relevant service guide SG before the service according to the normal service acquisition flow of BCAST, and extracts the service content concerned by the terminal from the relevant content and information of SG. The terminal determines whether to perform functions such as subscription/unsubscribe/watching/scheduled playing by browsing the content of the SG.
Step S202, the terminal configures the parameters of the receiving device on the terminal, and receives the relevant service content on the specified channel at the specified time.
After the terminal user selects the program content to be played by the terminal through the SG, the terminal configures parameters of a receiving device on the terminal according to the preset configuration and the Access fragment data in the SG, and receives the relevant service content on the specified channel at the specified time. After receiving the related service content, the received service content is submitted to the client of the terminal, and the client of the terminal presents the service content to the user, so that the user can watch the program which the user wants to play.
Step S203, the terminal determines the provision of the play control function according to the play information prompted by the SG.
In the process of playing a program by a terminal, the terminal needs to check a Service or Content related segment in an SG, and determine whether the Service Content being played provides a related playing control function, for example: play, pause, or fast forward, etc. If the service system does not provide the play control function, the play control function will not be opened to the terminal. If the Service system provides a play control function, the Service system prompts play information in the Service of the SG or the related data fragment of the Content; and if the SG does not prompt the terminal with relevant playing information, the terminal processes according to a normal playing flow.
Step S204, the terminal initiates a content playing control request to the server through the interactive channel.
If the service system provides the relevant play control function, for example: the play, pause, or fast forward function, the address of the media play control server carrying the play control function in the Service and the Content in the SG is required, and the relevant format that the Content play control request should take when the terminal sends the Content play control request to the media play control server is specified. After the terminal acquires the relevant playing information provided by the SG, a content playing control request is submitted to the address of the media playing control server according to the requirement of a user. For example: when the user needs to Pause the playing of the Service, the terminal needs to first acquire the time information of the currently played Service Content from the received TS (transport stream), and simultaneously submit the related information of the previous Service and the Content and the operation information of the Pause that the terminal needs to adopt to the media playing control server in the HTTP manner and by using XML (extensible markup language) data to carry the related information.
Step S205, the terminal and the media playing control server perform operations such as authentication and authorization.
After the media play control server receives the content play control request sent by the terminal, the media play control server may require the user to provide a user name and a password according to the content play control request submitted by the terminal, and performs authentication and authentication by using a PAP (password authentication protocol) or CHAP (challenge handshake authentication protocol) manner, so as to ensure that the terminal has the right to perform a related play control function, and also provide a related charging control function for a service provider.
In step S206, the media playing control server responds to the content playing control request sent by the terminal.
After the media playing control server determines that the user has the right to perform the related content playing control request according to the identity information of the terminal user, and determines that the service content can perform the related service control function according to the related program and the operation information carried by the terminal user, the media playing control server will send a response message to the terminal, for example: 200Ok, the response message carries success information to the terminal, and the service content played by the terminal is in a pause state.
Step S207, the terminal acquires the played service content.
And the terminal acquires the related playing content through the RTSP/HTTP. When the end user wants to be able to recover the playing function of the original service content, the end user submits a relevant playing request to the media playing control server in three steps of step S204, step S205 and step S206 by means of an HTTP request. The server sends an SDP (session description protocol) file of the service content to be played subsequently by the terminal to the terminal local in an HTTP manner, and the terminal local develops a subsequent playing function according to the information of the SDP file. After acquiring the SDP file information, the terminal software requests a multi-service content playing operation from the server in an RTSP mode. The terminal acquires the related media stream through RTP/RTCP. Meanwhile, the terminal may use SIP (session initiation protocol) instead of RTSP protocol to perform a related playing process.
The above-described procedure is an embodiment of a method for playing service contents under BCAST service. The implementation of which depends on the specific requirements, and the protocols used may also vary.
The method for playing the service content realizes the playing of the mobile multimedia service content through the existing network, so that the user can obtain the same user experience and feeling as the playing of the local service content when the user develops the multimedia broadcasting service. The embodiment of the invention combines the broadcast channel and the interactive channel, and realizes the playing of the mobile multimedia broadcast service content through content distribution modes of different approaches. The real-time media stream transmission is realized by utilizing the characteristic of large capacity of the broadcast channel, and the playing of non-real-time/delay content is realized by adopting a mode of combining the broadcast channel and the interactive channel.
As shown in fig. 3, a flowchart of a second embodiment of the method for playing service content of the present invention is shown, and the second embodiment is an embodiment of a method for playing service content under BCAST service. The service content playing method adopted in the second embodiment combines the broadcast content transmission mode and the interactive channel content mode, and completes the related functions in a mode of assisting the service guide of the SG and reporting the information of the related interactive channel. According to the process of service development, the second embodiment specifically includes:
in step S301, the terminal acquires the content and information of the service guide SG, and extracts the service content concerned by the terminal from the content and information of the SG.
The terminal acquires the content and information of the relevant service guide SG before the service according to the normal service acquisition flow of BCAST, and extracts the program content concerned by the terminal from the relevant content and information of SG. The terminal determines whether to perform functions such as subscription/unsubscribe/watching/scheduled playing by browsing the content of the SG.
Step S302, the terminal configures parameters of a receiving device on the terminal, and receives related service content on a specified channel at a specified time.
After the terminal user selects the service content to be played by the terminal through the SG, the terminal configures parameters of a receiving device on the terminal according to the preset configuration and the Access fragment data in the SG, and receives the relevant service content on a specified channel at a specified time. When a terminal user selects service content, the terminal user can select two types of service content, wherein one type is that all users watch the same service content in a broadcasting mode; the other is that each user individually selects the service content that the user likes to watch, and enjoys the service content through an interactive channel, which is called the service content on demand.
Step S303, the terminal reports the playing condition of the service content.
When playing the service content, the terminal also browses through SG to access the relevant service content. The terminal reports the local playing condition to the media playing control server in the process of playing the service content, and the media playing control server also records the playing condition of the terminal when sending the service content to the terminal.
In step S304, the media playback control server determines whether to switch the transmission of the media stream to a broadcast manner. When the media playing control server detects that the service content played locally by the terminal is the same as the content played in the broadcast channel, the media playing control server can judge whether the service needs to be switched from the on-demand mode of the interactive channel to the broadcast channel mode according to the user information. The user information includes user's selection, and user's terminal parameters.
In step S305, the media playing control server switches the interactive channel to the broadcast channel.
The media playing control server informs the terminal through Push mode or other signaling mode, such as SIP, to make the terminal start the receiving device of the broadcast channel and display the received service content on the terminal.
Step S306, the user watches the requested service content through the broadcast channel.
The terminal completes the alignment work of the media stream locally through the timestamp of the media stream, and presents the service content to the user, thereby ensuring that the user can watch the service content smoothly. After the terminal completes the action of playing the requested service content in a broadcasting manner, the subsequent playing action is the same as the manner described in the first embodiment.
The method for playing the service content realizes the playing of the mobile multimedia service content through the existing network, and determines whether to switch the service from the on-demand mode of the interactive channel to the broadcast channel according to the playing condition of the service content reported by the terminal and the user information, so that the user can watch the on-demand service content through the broadcast channel. Therefore, when the user develops the multimedia broadcasting service, the user experience and feeling which are the same as the content of the broadcast local service can be obtained. The embodiment of the invention combines the broadcast channel and the interactive channel, and realizes the playing of the mobile multimedia broadcast service content through content distribution modes of different approaches.
As shown in fig. 4, a flowchart of a third embodiment of a method for playing service contents according to the present invention is shown, where the third embodiment is an embodiment of a method for playing service contents under BCAST service, and the third embodiment introduces how a user suspends a current playing operation and resumes a related playing operation within an appropriate time while watching a real-time mobile multimedia broadcasting service. The basic method adopted by the third embodiment is to combine the broadcast content delivery mode and the interactive channel content delivery mode, and to complete the related functions with the service guide of SG. According to the process of service development, the third embodiment specifically includes:
in step S401, the terminal acquires the content and information of the service guide SG, and extracts the service content concerned by the terminal from the content and information of the SG.
The terminal acquires the content and information of the relevant service guide SG before performing the service according to the normal service acquisition flow of the BCAST, and extracts the service content concerned by the terminal from the content and information of the SG. The terminal determines whether to perform functions such as subscription/unsubscribe/watching/scheduled playing by browsing the content of the SG.
Step S402, the terminal configures parameters of the receiving device on the terminal, and receives the relevant service content on the specified channel at the specified time.
After the terminal user selects the program content to be played by the terminal user through the SG, the terminal configures the parameters of the receiving equipment on the terminal according to the preset configuration and the Access fragment data in the SG, and receives the relevant service content on the specified channel at the specified time. When selecting service content, a terminal user can select two types of programs, wherein one type is that all users watch the same service content in a broadcasting mode; another is that each user individually selects the favorite program to enjoy the service content through the interactive channel, which is called the on-demand service content.
Step S403, the terminal determines whether the playing of the service content can be controlled according to the playing information indicated by the SG.
And in the process of playing, the terminal judges whether the playing of the service content can be controlled or not according to the playing information indicated by the SG. The playing control involved in the third embodiment is mainly the playing control of the service content pause, and meanwhile, the playing of the service content can be resumed in a broadcasting manner.
Step S404, the terminal sends a content playing control request to the media playing control server through the interactive channel.
The Service system provides a relevant play control function, that is, a play control function similar to play pause is provided, the Service and the Content in the SG need to carry the address of the media play control server of the play control function, and the terminal is specified to adopt a relevant format when sending a Content play control request to the media play control server. After the terminal acquires the relevant information, a content playing control request is submitted to the address of the media playing control server according to the judgment of the user. If the user desires to pause the playing of the service. The terminal needs to first obtain the current playing time information from the received TS stream, and simultaneously submit the previous Service and Content related information and the Pause operation information that the terminal needs to use to the media playing control server in the HTTP manner and by using the XML data carrying the related information.
Step S405, the terminal and the media playing control server perform operations such as authentication and the like.
The media playing control server may require the terminal user to provide a user name and a password according to the content playing control request submitted by the terminal, and performs authentication and authentication by using a PAP or CHAP mode, so as to ensure that the terminal has the authority to perform a related playing control function, and simultaneously provide a related charging control function for a service provider.
In step S406, the media playing control server responds to the content playing control request provided by the terminal.
After the media playing control server determines that the user has the right to perform the related request according to the identity information of the terminal user, and determines that the service content can perform the related service control function according to the related service content and the operation information carried by the terminal user, the media playing control server sends a response message to the terminal, for example: 200Ok, the response message carries success information to the terminal, and the service content played by the terminal is in a suspended state.
Step S407, the terminal receives the content of the data broadcast issued by the media play control server through the data broadcast. The media playing control server will carry the relevant parameter information of the relevant data broadcast in the response message, including the accessed parameter, the decrypted key and other contents. The terminal receives the related content of the data broadcast while suspending playing the service content through the parameters. The related content of the data broadcast is a data delivery form of the service content, namely, the encoded service content. The terminal can complete actions similar to the playing of the service content by playing the service content of the data broadcast.
Step S408, the terminal resumes playing the service content. After receiving the data broadcast content, the terminal caches the data broadcast content in a local storage space and waits for the terminal user to resume playing of the service content. Considering the realizability problem, the receiving time of the data broadcasting content may have a certain length limitation, which is not considered in the embodiment of the present invention.
Step S409, the terminal plays the service content received through the data broadcast, and the data broadcast continues at the same time.
And the terminal plays the service content received by the data broadcast and displays the service content locally at the terminal. When the terminal plays the service content, the temporary storage content related to the playing can be deleted.
Step S410, the terminal completes playing the service content and exits the service content.
In the third embodiment, in the implementation process, the play control function is realized by multiplexing the broadcast service, so that the requirement of local coding is reduced, and the requirement on the terminal capability is greatly reduced.
As shown in fig. 5, it is a flowchart of a fourth embodiment of a method for playing service contents according to the present invention, where the fourth embodiment is an embodiment of a method for playing service contents under BCAST service, and the fourth embodiment introduces how a user suspends a current playing operation and resumes a related playing operation within an appropriate time while watching a real-time mobile multimedia broadcasting service. The basic method adopted by the fourth embodiment is to combine the content delivery mode of broadcasting and the content delivery mode of interactive channels, and to complete the related functions with the service guide of SG. According to the process of service development, the fourth embodiment specifically includes:
step S501, the terminal acquires the content and information of the service guide SG, and extracts the service content concerned by the terminal from the content and information of the SG.
The terminal acquires the content and information of the relevant service guide SG before performing the service according to the normal service acquisition flow of the BCAST, and extracts the program content concerned by the terminal from the content and information of the SG. The terminal determines whether to perform functions such as subscription/unsubscribe/watching/scheduled playing by browsing the content of the SG.
Step S502, the terminal configures parameters of a receiving device on the terminal, and receives related service content on a specified channel at a specified time.
After the terminal user selects the program content to be played by the terminal through the SG, the terminal configures parameters of a receiving device on the terminal according to the preset configuration and the Access fragment data in the SG, and receives the relevant service content on the specified channel at the specified time. When a terminal user selects service content, the terminal user can select two types of programs, wherein one type is that all users watch the same service content in a broadcasting mode; another is that each user individually selects the service content that the user likes to watch, and enjoys the service content through an interactive channel, which is called service content on demand.
In step S503, the user suspends playing the service content.
And the terminal judges whether the playing of the service content can be controlled or not through the playing information indicated by the SG in the playing process. The playing control function in the fourth embodiment is mainly to pause the playing of the service content, and at the same time, to resume the playing of the service content through the storage server on the network side.
Step S504, the terminal sends a temporary storage request to the network server through the interactive channel.
The terminal determines whether the service can provide a related play control function, that is, in the fourth embodiment, whether the service provides a function of caching the service content by the related network storage server. When the Service can provide a relevant play control function, the Service and the Content of the SG need to carry the address of the media play control server of the play control function, and the terminal is specified to adopt a relevant format when sending a Content play control request to the media play control server. After the terminal acquires the relevant information, a content playing control request is submitted to the server address according to the judgment of the user. Caching the play-out of the service as required by the user. The terminal needs to first obtain the current playing time information from the received TS stream, and simultaneously submit the previous Service and Content related information and the Pause operation information that the terminal needs to use to the media playing control server in the HTTP manner and by using the XML data carrying the related information.
Step S505, the terminal and the media playing control server perform operations such as authentication and authorization.
The media playing control server may require the user to provide a user name and a password according to the temporary storage request submitted by the terminal, and performs authentication and authentication by using a PAP or CHAP mode to ensure that the terminal has the authority to perform a related media playing content caching function. The media playing control server judges that the terminal user has the authority to carry out the related temporary storage request according to the identity information of the terminal user, and judges whether the service content can carry out the cache function of the related playing content according to the related service content and the operation information carried by the terminal user. In such a case, the media playing control server will carry success information to the terminal through the response message of 200Ok, and the service content played by the terminal is in a suspended state.
Step S506, after completing the corresponding authorization and request, the network side server caches the service content.
Step S507, after the terminal recovers the playing process of the service content, the terminal retrieves the cached service content from the cache server through the relevant protocol. These protocols may be RTSP/RTP/RTCP and the like, and may also be HTTP and other download protocols.
Step S508, the terminal locally plays the cached service content.
In step S509, after the terminal finishes playing the service content, the terminal notifies the cache server to stop caching the relevant service content through a protocol such as HTTP. If a program stops playing, the cache server can also automatically stop the caching of the service content according to the setting of the terminal.
The playing control method of the business content is carried out in a mode of caching the business content at the network side. When the service content supports such a mode, and the problem of digital copyright does not exist, the playing control of the cache can be carried out in such a mode. The method saves the local storage space of the terminal and the calculation amount of encoding and decoding, and is more suitable for the playing control of the mobile terminal.
