Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method and device for determining a service. Background Art

[0002] With the growth of bandwidth and the improvement of hardware performance, the demand for synchronous viewing is becoming more and more common in order to improve user experience and participation. Synchronous viewing allows multiple users to watch the same media file or program simultaneously across terminals and regions. For example, multiple users can watch a football game together. The prerequisite for synchronous viewing is that multiple users need to access the same service (i.e., media file or program, etc.) to achieve synchronous viewing. Therefore, a service determination method is urgently needed to ensure that multiple users can access the same service. Summary of the invention

[0045] The present application will be described in further detail below in conjunction with the accompanying drawings.

[0046] The embodiments of the present application provide a method and device for determining a service, so as to ensure that multiple users can access the same service. The method and device described in the present application are based on the same technical concept. Since the method and device solve the problem in a similar way, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0047] In the description of this application, words such as “first” and “second” are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance or order.

[0048] In the description of this application, "at least one" means one or more, and more means two or more. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, a and b, a and c, b and c, or a, b and c, where a, b, c can be single or plural.

[0049] In the description of this application, "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. " / " means "or", for example, a / b means a or b.

[0050] In order to more clearly describe the technical solution of the embodiment of the present application, the method and device for determining the service provided by the embodiment of the present application are described in detail below with reference to the accompanying drawings.

[0051] The embodiments of the present application can be applied to various business scenarios such as internet protocol television (IPTV), digital broadcasting, and OTT (over the top) video.

[0052] For example, Figure 1 The architecture of an IPTV system to which the service determination method provided in the embodiment of the present application is applicable is shown. The architecture may include a content provider, an IPTV management network, an IPTV platform, a real-time communication (RTC) network, a bearer network, and multiple clients. Figure 1 In the figure, a plurality of clients including client 1, client 2 and client 3 are taken as an example.

[0053] Among them, the content provider can provide IPTV media stream (IPTV media stream) to the client through the IPTV platform.

[0054] The business operating support system (BOSS) of the IPTV management network is used for user account opening management and provides user account opening data (user onboarding) to the IPTV platform. In turn, the IPTV platform can authenticate and authorize user service access, while the content delivery network (CDN) transmits IPTV media streams to the client through the bearer network.

[0055] The IPTV management platform can provide the account opening data to the RTC network. In turn, the RTC network can transmit RTC signaling to the client through the bearer network, and the RTC network can establish an RTC media or data channel with the client through the bearer network.

[0056] For example, the RTC network may include a website RTC (WebRTC) and an IP multimedia subsystem (IMS), etc.

[0057] The multiple clients may include a master client, which can initiate synchronous viewing (also known as cloud viewing), that is, the master client can invite other clients to achieve multi-client synchronous playback of the same media file. Figure 1 Client 1 can be the main client, and client 1 initiates synchronous viewing with client 2 and client 3.

[0058] The client may be a digital video broadcasting-internet (DVB-I) client. For example, the client may include, but is not limited to, a terminal device such as a television, a mobile phone, a tablet computer, a laptop computer, or a PDA. Optionally, the client may include an IPTV application (application, app) and / or an IPTV software development kit (software development kit, SDK), and the client may receive IPTV media streams or IPTV identity authentication information through the IPTV app or IPTV SDK. The client may also include an RTC app, and the client may receive RTC signals and maintain RTC media or data channels through the RTC app.

[0059] It should be understood that Figure 1 This is merely an illustrative description of a system to which the embodiments of the present application are applicable and is not intended to limit the present application.

[0060] Currently, DVB-I is a specification defined by digital video broadcasting (DVB) for discovering services on the Internet. The architecture diagram of DVB-I can be shown as follows: Figure 2 As shown. Among them:

[0061] The content / service provider sends the service list that can be provided to the service list server. The service list server registers the service list access entry address (such as the uniform resource locator (URL)) to the service list registry. When the DVB-I client wants to discover a service, the DVB-I client obtains the service list access entry address from the service list registry through the address of the service list registry. The DVB-I client then queries the corresponding service list through the access entry address.

[0062] In a service list, a logical channel number (LCN) list (table) and a service list may be included. The LCN table may include LCN, a target region list and a subscription package. The LCN includes a channel number and a service identity (service ID). The target region list included in the LCN indicates the area where the LCN is applicable, and the subscription package indicates the contract package applicable to the LCN. The service includes a service ID, a target region list and a service instance list. The service ID included in the service is used to associate the service with the LCN; the target region list is used to indicate the area where the service is applicable; the service instance list indicates an instance of the service provided (such as through digital terrestrial broadcasting (Digital Video Broadcasting-Terrestrial, DVB-T), DVB-based on hypertext transfer protocol (hyper text transfer protocol, HTTP) dynamic adaptive streaming (dynamic adaptive streaming over HTTP, DASH), digital cable TV (Digital Video Broadcasting-Cable, DVB-C), and digital satellite TV (Digital Video Broadcasting-Satellite, DVB-S), etc.). The service instance includes priority and subscription package. The subscription package included in the service instance is used to indicate the subscription package applicable to the service instance.

[0063] After receiving the service list, the DVB-I client will match the service list according to the target region and subscription package applicable to the service list and its own region and subscription information, and display the matched services and LCN to the user according to the content guide data.

[0064] In a scenario where synchronized viewing is required, the user as the main client selects services (such as programs, media) based on the services and LCN displayed by the DVB-I client. Since the DVB-I client only displays services that can be accessed by users of the main client to the user, the user may select services that are inaccessible to other users participating in different viewings. In this case, synchronized viewing cannot be carried out, affecting the user experience. Based on this, an embodiment of the present application provides a method for determining a service, which can ensure that multiple users access the same service, thereby successfully achieving synchronized viewing and improving the user experience.

[0065] Based on the above description, this embodiment of the application provides a method for determining a service. Figure 3 As shown, the method may include the following steps:

[0066] Step 301: A first client sends a first service request message to a first server. Correspondingly, the first server receives the first service request message from the first client. The first service request message may include an identifier of the first client and an identifier of a second client.

[0067] The first client is the main client, that is, the first client can determine to initiate synchronous viewing, which can also be understood as the user of the first client inviting users of one or more other clients to watch synchronously. In this application, the user of the first client invites the user of the second client to watch synchronously as an example.

[0068] In one example, after the first client decides to initiate synchronous viewing, it can send a request to establish a video call or video conference with the second client through the RTC network to establish a media interface and a data channel between the first client and the RTC network. Furthermore, the RTC network interacts with the second client to establish a media interface and a data channel to establish a video call or video conference between the first client and the second client. Among them, a video call can refer to a call involving two parties, and a video conference can refer to a call involving three or more parties. It should be understood that video calls and video conferences are only examples, and other communication methods that can achieve synchronous viewing are all possible, and this application does not limit this.

[0069] It should be understood that users of the first client can also realize synchronous viewing of movies by more than two users with users of other clients except the second client. Here, only the second client is used as an example for explanation, and the same is true for other clients. This application does not limit this.

[0070] In some embodiments, the first client may pre-store the identification of the second client.

[0071] Optionally, when the first client and the second client are mobile phones, the identifier of the first client and the identifier of the second client may be, but are not limited to, corresponding mobile phone numbers and the like.

[0072] Optionally, the first client and the second client may be DVB-I clients.

[0073] Among them, the first server can be understood as a server that helps to achieve synchronous movie viewing. For example, the first server can include a synchronous movie viewing server, etc.

[0074] Step 302: The first server determines a first service set according to the identifier of the first client and the identifier of the second client. The first service set includes at least one service, and the at least one service is used for access by the first client and the second client.

[0075] In an optional implementation, the first server may determine the client information of the first client based on the identifier of the first client, and determine the client information of the second client based on the identifier of the second client; further, the first server may determine the first service set based on the client information of the first client and the client information of the second client.

[0076] The first server determines the client information of the first client according to the identifier of the first client, and determines the client information of the second client according to the identifier of the second client, which may include the following method a1 and method a2:

[0077] Method a1: The first server may determine the client information of the first client in the local configuration information according to the identifier of the first client, and determine the client information of the second client in the local configuration information according to the identifier of the second client.

[0078] In method a1, the first server local configuration includes client information of the first client and client information of the second client. Therefore, the first server can directly obtain the client information of the first client and the client information of the second client from the local configuration based on the identifier of the first client and the identifier of the second client respectively.

[0079] Method a2: The first server may obtain the client information of the first client from the first device according to the identifier of the first client, and obtain the client information of the second client from the first device according to the identifier of the second client.

[0080] Exemplarily, the client information of the first client may include at least one of the following information: information about the region where the first client is located (such as the region of the first client) and contract information of the first client (such as the subscription package of the first client). The client information of the second client may include at least one of the following information: information about the region where the second client is located (such as the region of the second client) and contract information of the second client (such as the subscription package of the second client).

[0081] In the present application, the region information may include location information, such as geographical location information, for example, a city, district, or county. For example, the region information where the first client is located may be the location where the first client is located, such as the city or district where the first client is located. For example, the region information where the second client is located may be the location where the second client is located, such as the city or district where the second client is located.

[0082] The contract information may include a subscription package, such as a subscribed package, a subscribed rate, a subscribed service or a level corresponding to the rate, etc. For example, the contract information of the first client may include the rate subscribed by the first client, etc., which is not limited in this application. For example, the contract information of the second client may include the rate subscribed by the second client, etc., which is not limited in this application.

[0083] It should be understood that the client information of the first client and the client information of the second client may also have other descriptions, and this application does not limit this.

[0084] In a possible implementation b1, the first server determines a first service set based on the client information of the first client and the client information of the second client. The method may include: the first server sends a second service request message to the second server, and receives the first service set from the second server; wherein the second service request message may include the client information of the first client and the client information of the second client; at least one service included in the first service set matches the client information of the first client and the client information of the second client.

[0085] For example, at least one service matches the client information of the first client and the client information of the second client, which may be considered as follows:

[0086] 1) If the service includes an LCN table and the LCN table includes a target region list and / or a subscription package, the regions where the first client and the second client are located are within the regions allowed by the target region and / or the contracts of the first client and the second client meet the requirements of the subscription package. (If the LCN table does not include a target region list and a subscription package, it is assumed that all clients meet the requirements).

[0087] 2) If the Service Instance (there may be multiple Service Instances) of the service includes a subscription package, the contract between the first client and the second client meets the requirements of the subscription package (if the Service Instance does not include a subscription package, it is considered that all clients meet the requirements). In order to provide the service, the contract between the first client and the second client must meet the requirements of the subscription package of at least one Service Instance.

[0088] 3) If the service includes an LCN table and the LCN table includes a target region list and / or a subscription package, and the Service Instance includes a subscription package, the first client and the second client must meet requirements 1) and 2) at the same time.

[0089] In this implementation b1, after the second server receives the second service request message including the client information of the first client and the client information of the second client from the first server, it determines the first service set according to the client information of the first client and the client information of the second client, and sends the first service set to the first server. In this way, the services in the first service set determined by the second server according to the client information of the first client and the client information of the second client are services that can be accessed by both the first client and the second client.

[0090] In a possible implementation b2, the first server determines the first service set according to the client information of the first client and the client information of the second client, and the method may include: the first server sends a third service request message to the second server, receives the second service set from the second server, and then the first server determines the first service set in the second service set according to the client information of the first client and the client information of the second client. The second service set includes at least one service; and the at least one service included in the first service set matches the client information of the first client and the client information of the second client.

[0091] In this implementation b2, after the second server receives the third service request message from the first server, it returns the second service set that can be provided to the first server to the first server. The first server can determine the services that the first client and the second client can access together in the second service set based on the client information of the first client and the client information of the second client.

[0092] Optionally, the first server may determine at least one service in the second service set that can be accessed by the first client and the second client together, that is, determine the first service set.

[0093] In a possible implementation b3, the first server determines a first service set based on the client information of the first client and the client information of the second client. The method may include: the first server sends a fourth service request message to the second server, the fourth service request message includes the client information of the first client; the first server receives a third service set from the second server, the third service set includes at least one service; the first server sends a fifth service request message to the second server, the fifth service request message includes the client information of the second client; the first server receives a fourth service set from the second server, the fourth service set includes at least one service; finally, the first server determines a first service set based on the third service set and the fourth service set, wherein the third service set and the fourth service set include the first service set; at least one service included in the first service set matches the client information of the first client and the client information of the second client.

[0094] In this implementation b3, after the second server receives the fourth service request message from the first server, it can match services according to the client information of the first client, and obtain the third service set that the first client can access; after the second server receives the fifth service request message from the first server, it can match services according to the client information of the second client, and obtain the fourth service set that the second client can access. Afterwards, the first server can determine the services that both the first client and the second client can access in the third service set and the fourth service set, that is, obtain the first service set.

[0095] Optionally, the first server may determine at least one service accessible to both the first client and the second client in the third service set and the fourth service set, that is, the first service set includes at least one service accessible to both the first client and the second client.

[0096] Exemplarily, the second server may be a service list server.

[0097] Any of the above service sets can be a service list.

[0098] In a possible manner, before sending any of the above service request messages to the second server, the first server may query the service list registry for the address of the second server, or the first server may obtain the address of the second server according to local configuration.

[0099] Step 303: The first server sends the first service set to the first client. Correspondingly, the first client receives the first service set from the first server.

[0100] Optionally, the first server may also send the address of the second server to the first client, so that the first client can query service information.

[0101] Step 304: The first client determines a first service in the first service set. The first service can be used for common access by the first client and the second client.

[0102] Since the services included in the first service set are services that can be accessed by both the first client and the second client, the first service determined by the first client in the first service set is a service that can be accessed by both the first client and the second client.

[0103] In one example, the first client may determine the first service in the first service set by the following method: the first client sends a request message to the content guide server to obtain the content guide data corresponding to the first service set, and receives the content guide data corresponding to the first service set from the content guide server. Then, the first client displays the information of the services included in the first service set to the user of the first client according to the content guide data corresponding to the first service set, and finally determines the first service in the first service set based on the instruction of the user of the first client.

[0104] Optionally, the user of the first client may use a remote controller or the like to select a service from the displayed service information, thereby triggering an instruction to the first client, so that the first client determines the service selected by the user (ie, the first service) based on the instruction.

[0105] After the first client determines the first service, the first client can determine a first service instance of the first service, where the first service instance includes at least one instance that provides the first service. For example, the first service instance is an instance that provides services through DVB-DASH, and the instance parameters include the address URI of a media presentation description (MPD) file server. For another example, the first service instance is an instance that provides services through a real-time streaming protocol (RTSP), and the instance parameters include the address URI for providing media.

[0106] In some embodiments, the first client may send a first message to the second client, and the first message may include information of the first service.

[0107] Exemplarily, the first client may send the first message to the second client via a data channel or RTC network control information.

[0108] Optionally, the information of the first service may include an identifier of the first service, or the information of the first service may include an identifier of the first service and other relevant information of the first service. For example, the identifier of the first service is the ID of the first service, and the identifier of the first service may be represented by a string, a number (such as a number, etc.), etc., which is not limited in this application. For example, other relevant information of the first service may include a service name, a service type, a service genre, a service instance, etc.

[0109] Optionally, the first message may further include an address of the second server, so that the second client can query the information of the first service.

[0110] Alternatively, the first client may send the address of the second server to the second client, so that the second client queries the information of the first service.

[0111] After the second client receives the first message, the second client may further determine the first service. For example, the second client may determine the first service by the following three methods:

[0112] Method c1: The second client may send a sixth service request message to the second server, wherein the sixth service request message includes client information of the second client; the second client receives a fifth service set from the second server, and determines the first service according to the information of the first service and the fifth service set. The fifth service set includes at least one service, and the at least one service is used for access by the second client.

[0113] In method c1, after receiving the sixth service request message, the second server can perform service matching according to the client information of the second client to obtain a fifth service set. Furthermore, the second client can determine the first service in the fifth service set according to the information of the first service.

[0114] For example, the second client may determine the first service in the fifth service set according to the identifier of the first service.

[0115] Method c2: The second client sends a seventh service request message to the second server; the second client receives a sixth service set from the second server, and determines the first service according to the information of the first service and the sixth service set. The sixth service set includes at least one service, and the at least one service is used for the second client to access.

[0116] In the method c2, after receiving the seventh service request message, the second server may take the services that can be provided to the second client as a sixth service set, and return the sixth service set to the second client.

[0117] In method c1 and method c2, before the second client requests service from the second server, the second client can obtain the address of the second server according to local configuration, or the second client can query the address of the second server from the service list registry, or the second client can obtain the address of the second server from the second client.

[0118] It should be understood that in the above methods c1 and c2, the second client requesting services from the second server is only an example, and the second server can be replaced by a third server. That is, the first client and the second client can request services from the same server or from different servers, and this application does not limit this.

[0119] Method c3: The second client determines the first service according to the information of the first service.

[0120] After the second client determines the first service, the second client may determine a second service instance of the first service, for example, the second service instance includes at least one instance that provides the first service. For example, the second service instance is an instance that provides services through DVB-DASH, and the instance parameters include the address URI of the MPD file server. For another example, the second service instance is an instance that provides services through RTSP, and the instance parameters include the address URI that provides media.

[0121] Optionally, the first service instance of the first service and the second service instance of the first service may be the same or different.

[0122] In some embodiments, the first client may send a first request message to the first playlist server, the first request message being used to request the media resource corresponding to the first service, and the first request message may include the first address of the first service. The first playlist server may determine the media resource corresponding to the first service according to the first address of the first service, and send the media resource corresponding to the first service to the first client. Then the first client may play the media resource corresponding to the first service.

[0123] In some other embodiments, the first client may use the DASH protocol to obtain media resources. For example, the first client may send a first MPD request message to a first MPD server, the first MPD request message may include a first address of a first service, the first MPD server determines a first MPD file corresponding to the first service according to the first address of the first service, and sends the first MPD file to the first client; further, the first client sends a first media request message to a first media stream server, the first media request message is used to request a media file corresponding to the first MPD file, the first media stream server sends the first media file to the first client, the first media file corresponds to the first service. Then, the first client can play the first media file corresponding to the first service.

[0124] In a possible manner, the second client may send a second request message to the second playlist server, the second request message being used to request the media resource corresponding to the first service, and the second request message may include the second address of the first service. The second playlist server may determine the media resource corresponding to the first service according to the second address of the first service, and send the media resource corresponding to the first service to the second client. Then the second client may play the media resource corresponding to the first service.

[0125] In another possible manner, the second client may use the DASH protocol to obtain media resources. For example, the second client may send a second MPD request message to the second MPD server, the second MPD request message may include the second address of the first service, the second MPD server determines the second MPD file corresponding to the first service according to the second address of the first service, and sends the second MPD file to the second client; further, the second client sends a second media request message to the second media streaming server, the second media request message is used to request the media file corresponding to the second MPD file, the second media streaming server sends the second media file to the second client, the second media file corresponds to the first service. Then, the second client can play the second media file corresponding to the first service.

[0126] Optionally, the first playlist server and the second playlist server may be the same or different, and this application does not limit this.

[0127] The first MPD server and the second MPD server may be the same or different, and this application does not limit this.

[0128] The first media stream server and the second media stream server may be the same or different, and this application does not limit this.

[0129] In an optional implementation, the first client may send playback synchronization information to the second client, so that the first client and the second client can play synchronously, thereby achieving synchronous viewing.

[0130] Based on the above service determination method, the first client can determine the services that the first client and the second client access together, thereby ensuring that multiple users access the same service, thereby successfully achieving synchronous viewing and improving user experience. At the same time, the first client does not need to obtain the client information of the second client, and the information of the second client can be protected.

[0131] Based on the above embodiments, Figure 4 The example shown in the figure describes in detail the method for determining the service provided by the embodiment of the present application. It should be understood that the following examples are only exemplary and are not intended to limit the present application. In this example, the first client and the second client use the same server (such as the second server, the playlist server, etc.). The first server is a synchronous movie viewing server.

[0132] For example, Figure 4An example of a method for determining a service is shown. In this example, a first client sends the identifiers of the first client and the second client to a synchronous movie viewing server. The synchronous movie viewing server determines the client information of the first client and the client information of the second client according to the identifiers of the first client and the second client, respectively. After interacting with the second service, the synchronous movie viewing server returns to the first client a service that both the first client and the second client can access. For example, see Figure 4 As shown, the process of this example may include the following steps:

[0133] Step 401: The first client determines to initiate synchronous movie viewing.

[0134] The first client chooses to watch the movie synchronously with the second client.

[0135] Step 402: The first client establishes a media interface and a data channel with the second client via the RTC network.

[0136] Exemplarily, the first client may send a request to establish a video call or a video conference with the second client to the RTC network, so that the first client and the second client establish a media interface and a data channel.

[0137] Step 401 and step 402 may also be performed after step 409, which is not limited in this application.

[0138] Step 403: The first client sends a first service request message to the synchronous movie viewing server, where the first service request message includes an identifier of the first client and an identifier of the second client.

[0139] Step 404: The synchronous movie viewing server determines the client information of the first client and the client information of the second client according to the identifier of the first client and the identifier of the second client respectively, and sends a second service request message to the second server, the second service request message including the client information of the first client and the client information of the second client.

[0140] The client information of the first client and the client information of the second client can be found in Figure 3 The relevant descriptions involved in the illustrated embodiments will not be repeated here.

[0141] Step 405: The second server determines a first service set according to the client information of the first client and the client information of the second client, and sends the first service set to the synchronous movie viewing server.

[0142] The first service set can be found in Figure 3 The relevant descriptions involved in the illustrated embodiments will not be repeated here.

[0143] Step 406: The synchronous movie viewing server sends a first service set to the first client.

[0144] Step 407: Optionally, the first client sends a request message to the content guide server to obtain content guide data corresponding to the first service set.

[0145] Optionally, the first service set also includes the address of a content guide server, and the first client may send a request message to the content guide server based on the address of the content guide server to obtain content guide data corresponding to the first service set.

[0146] Step 408: The content guide server sends content guide data corresponding to the first service set to the first client.

[0147] Step 409: The first client displays service information that can be accessed by the first client and the second client to the user of the first client. If content guide data is requested, the displayed information also includes the content guide data. Based on the instructions of the user of the first client, the first service is determined in the first service set, and the first service instance of the first service is determined.

[0148] The description of the first client determining the first service in the first service set based on the instruction of the user of the first client can be found in Figure 3 The description involved in the illustrated embodiments will not be repeated here.

[0149] Step 410: The first client sends a first message to the second client, where the first message may include information about the first service.

[0150] For a description of the information of the first service, please refer to the aforementioned Figure 3 The description involved in the illustrated embodiments will not be repeated here.

[0151] Step 411: the second client sends a sixth service request message to the second server, where the sixth service request message includes client information of the second client.

[0152] Optionally, if the information of the first service includes an identifier of the first service, the second client executes step 411 .

[0153] Step 412: The second server determines a fifth service set according to the client information of the second client, and sends the fifth service set to the second client.

[0154] Step 413: the first client sends a first request message to the playlist server. The first request message is used to request the media resource corresponding to the first service. The first request message may include a first URI corresponding to the media resource of the first service.

[0155] Step 414: the playlist server determines the media resource corresponding to the first service according to the first URI of the first service, and sends the media resource corresponding to the first service to the first client.

[0156] Step 415: The first client plays the media resource corresponding to the first service.

[0157] Step 416: The second client determines the first service according to the information of the first service and the fifth service set, and determines a second service instance of the first service.

[0158] Step 417: the second client sends a second request message to the playlist server. The second request message is used to request the media resource corresponding to the first service. The second request message may include a second URI corresponding to the media resource of the first service.

[0159] Step 418: The playlist server determines the media resource corresponding to the first service according to the second URI of the first service, and sends the media resource corresponding to the first service to the second client.

[0160] Step 419: The second client plays the media resource corresponding to the first service.

[0161] Step 420: The first client sends playback synchronization information to the second client, so that the first client and the second client can play synchronously.

[0162] Through the above example, the first client can select a service that both the first client and the second client can access based on the service returned by the synchronous movie viewing server, thereby ensuring that multiple users access the same service. At the same time, the first client does not need to obtain the client information of the second client, and the information of the second client can be protected.
