Please refer to Figure 2, the STB cloudification method provided by an embodiment of this application can be applied to the vSTB shown in Figure 1, the method includes the following steps.

Step 101, obtain a connection request sent by a thin set-top box tSTB, and establish a connection channel with the tSTB based on the connection request.

Step 103: Receive input information corresponding to the local device sent by the tSTB through the connection channel, determine the type of service application based on the input information, obtain a corresponding processing result, and return it to the tSTB.

Here, the connection channel between the tSTB and the corresponding vSTB refers to the corresponding vSTB address based on the corresponding relationship between the tSTB and the corresponding vSTB resource, such as the corresponding vSTB address determined according to the identity of the tSTB. Corresponds to the network interconnection channel between vSTBs. The type of business application refers to the category that classifies business applications according to the business they implement. As the entrance of home multimedia services, set-top boxes can be triggered by human-computer interaction and interact with different business applications, such as Electronic Program Guide (EPG), Content Delivery Network (CDN), games, advertisements and messages, etc. The communication and interaction between servers implement different services and classify them into three main types of business applications: cloud applications, semi-cloud applications, and local applications. Input information refers to the input information received by tSTB corresponding to the local equipment, such as voice, gesture, and command messages input by remote control, keyboard, handle, USB peripherals, etc., that is, the user can operate the remote control corresponding to tSTB , Keyboards, handles, USB peripherals and other local devices to input operating instructions to start designated business applications.

In the above-mentioned embodiments of this application, the vSTB can receive the input information of the corresponding local device sent by the tSTB through the connection channel established with the corresponding tSTB. The input information can be input by the user by operating the local device corresponding to the tSTB For current business requirements, vSTB determines the type of business application based on the received input information and obtains the corresponding processing result and returns it to the tSTB. In this way, the business application can be classified and a connection channel can be established between the tSTB and the corresponding vSTB , Can realize different types of business applications between tSTB and corresponding vSTB, such as the processing of business applications with different degrees of cloudification, by forming business applications into types with different degrees of cloudification, and through the collaborative interaction of tSTB and corresponding vSTB Realize the processing of business applications, thereby facilitating rapid business deployment and rapid iteration; secondly, business deployment and upgrades can reduce the reliance on STB hardware, thereby continuously reducing costs, taking into account the continuity of cost and business development.

In some embodiments, the determining the type of the business application based on the received input information and obtaining the corresponding processing result to return to the tSTB includes: in the case of determining that the business application is a cloud application based on the input information, and The application server interacts to obtain display data and/or audio data, and returns the display data and/or audio data to the tSTB as a processing result.

Here, cloud-based applications refer to business applications that run and process entirely in the cloud. Based on the input information sent by the received tSTB, when the vSTB determines that the business application is a cloud application, it is processed directly on the vSTB side, and the vSTB interacts with the corresponding application server to obtain display data and/or audio data in response to the input information. And the response display data and/or audio data are returned to tSTB as the processing result. The display data may include at least one of the following: graphic display data, video display data, and graphic superimposed video display data.

In some embodiments, the obtaining display data and/or audio data by interacting with the application server based on the input information, and returning the display data and/or audio data to the tSTB as a processing result includes: The input information interacts with the business system to obtain graphic display data; based on the input information interacts with the CDN server to obtain video display data; the graphic display data and the video display data are superimposed and mixed at the pixel level, and the mixed The graphic display data and the video display data of are returned to the tSTB as a processing result.

Here, for cloud applications, processing is directly performed on the vSTB side. The vSTB interacts with the corresponding business system to obtain graphic display data in response to the input information, and interacts with the corresponding CDN server to obtain video display data in response to the input information , And complete the superimposition and mixing of the display on the vSTB side, and return the graphic display data and video display data after the response superimposition and mixing to the tSTB as a processing result. Since all displays are superimposed and mixed on the vSTB side, only the RGB components need to be video encoded and streamed to tSTB.

In some embodiments, before returning the display data and the remote call instruction to the tSTB as a processing result, the method includes: performing video encoding and streaming on the RGB components in the display data, The ()) Alpha (Alpha) component is compressed and encoded and streamed; the video encoding stream of the RGB component and the compressed encoding stream of the Alpha component are used as the display data returned to the tSTB.

Here, for semi-cloud applications, different business parts that are directly processed on the vSTB side and processed on the tSTB side are included respectively. Wherein, before the display data obtained by processing on the vSTB side is sent to tSTB for display, the vSTB also includes performing video encoding and streaming on the RGB components in the display data, and compressing and encoding the Alpha components in the display data Streaming, and using the video encoding stream of the RGB component and the compression encoding stream of the Alpha component as the display data returned to the tSTB. In this way, for the display data sent by vSTB, the tSTB side needs to receive the video encoding stream of RGB component and the compressed encoding stream of Alpha component at the same time, and perform video decoding or decompression processing to decode the decoded RGB data and decompressed Alpha data. Merge and restore to RGBA display data, and then present it again to achieve seamless superposition and integration of vSTB-side processing results and tSTB-side processing results.

In the above-mentioned embodiment of the present application, in a semi-cloud application scenario, compared to the scheme of directly sending the video encoding stream of the RGB component of the display data to tSTB by vSTB, it ensures that the Alpha transparency component will not be lost and avoids tSTB restoration. Due to the lack of alpha transparency, the vSTB side display will completely cover the tSTB side local display when superimposed with the local display content, resulting in abnormal display after synthesis (that is, the local display on the tSTB side is not visible).

In some embodiments, before returning the display data and the remote call instruction as the processing result to the tSTB, the method includes: intercepting the interface call of the cloud application and determining the type of the interface call; determining the interface call When it is a call type processed by the vSTB side, the interface call is processed at the local end; when it is determined that the interface call is a call type that is not processed by the vSTB side, the interface call is used as a remote call instruction returned to the tSTB.

There are often mutual calls and interoperability between different business applications, such as portal and portal-level applications. For scenarios where there is communication interaction and interoperability between cloud applications and local applications, vSTB intercepts the interface calls of cloud applications and judges the type of interface calls; when it is determined that the interface calls are the call types processed by the vSTB side, The local end processes the interface call; when it is determined that the interface call is a call type that is not processed by the vSTB side, the interface call is used as a remote call instruction returned to the tSTB, and the interface is called through the system agent or application agent The redirection is sent to tSTB for processing. Based on this interface call, tSTB obtains the processing result and returns it to vSTB, and vSTB returns the processing result to the cloud application, so that the application is unaware of the changes caused by cloudification.

In some embodiments, said interacting with the application server to obtain display data, and returning the display data and remote call instruction as a processing result to the tSTB includes: interacting with a business system to obtain a visual communication user interface UI The interface graphic display data of the interface graphic display data and the media control command are returned to the tSTB as a processing result.

Here, for the semi-cloud visual communication application, the user interface UI, protocol, and service processing are implemented on the vSTB side, and the media transceiving and coding and decoding processing are implemented locally on the tSTB side, and finally the UI and video are superimposed and mixed on the tSTB side. When vSTB determines that the business application is a semi-cloud visual communication application based on the input information, it interacts with the business system to obtain the interface graphic display data of the visual communication user interface UI, and displays the interface graphic data and media The control command is returned to the tSTB as a processing result. The tSTB receives the media control commands returned by the vSTB for processing, and blends the video display data generated by its own processing with the graphical display data of the visual communication UI interface returned by the vSTB, and displays them.

In the above-mentioned embodiments of this application, for the semi-cloud processing of visual communication applications, the new UI deployment only needs to be connected once in the cloud, without adapting to various STBs on the existing network, and without considering the differences in STB hardware, so that the corresponding service deployment is not Depends on the number of users and tSTB hardware configuration, which facilitates rapid business deployment, rapid iteration, and both cost and business development continuity.

In some embodiments, said interacting with the application server to obtain display data, and returning the display data and remote call instructions as processing results to the tSTB includes: interacting with the business system to obtain the interface graphics of the cloud application Display data, returning the interface graphic display data and application control commands to the tSTB.

Here, for the switch between cloud-based applications and local applications, for example, the cloud-based portal EPG application on the vSTB side pulls up the local application on the tSTB side. vSTB interacts with the business system to obtain the interface graphic display data and application control commands of the cloud application and return it to tSTB for tSTB to process the application control commands and start the local application to the foreground. The tSTB receives user input and presents it based on the startup of the local application , So that the application is unaware of the changes caused by cloudification.

In some embodiments, the obtaining the connection request sent by the thin set-top box tSTB, before establishing a connection channel with the tSTB based on the connection request, includes: obtaining the login authentication request sent by the vSTB management platform based on the tSTB The vSTB resource allocation request; based on the vSTB resource allocation request, a corresponding vSTB address is returned, and the vSTB address is used to return to the corresponding tSTB.

Here, the vSTB obtains the vSTB resource allocation request sent by the vSTB management platform based on the tSTB login authentication request, and returns the corresponding vSTB address based on the vSTB resource allocation request, and the vSTB address is used to return to the corresponding tSTB, Initiate login authentication to the vSTB management platform through tSTB, allocate vSTB resources to tSTB after passing the authentication of the vSTB management platform, and return the vSTB address to tSTB so that tSTB can initiate a connection request and establish a connection channel based on the vSTB address.

Referring to FIG. 3, another aspect of the embodiment of the present application also provides a cloudification method for STB of a set-top box, which can be applied to the vSTB management platform shown in FIG.

Step 201: Obtain a login authentication request sent by the tSTB, and send a vSTB resource allocation request to the vSTB according to the login authentication request.

Step 203: Receive the vSTB address returned by the vSTB and send it to the tSTB, where the vSTB address is used to establish a connection channel between the tSTB and the corresponding vSTB.

Here, the login authentication request carries identification information used to characterize the identity of the tSTB. The establishment of a connection channel between the tSTB and the corresponding vSTB is based on the tSTB sending a login authentication request to the vSTB management platform, and receiving the vSTB management platform to determine the corresponding vSTB resource through the authentication and login, and the use of the establishment between the tSTB and the corresponding vSTB resource To realize the network interconnection channel between tSTB and the corresponding vSTB.

In the above-mentioned embodiment of this application, the vSTB management platform allocates corresponding vSTB resources to the tSTB through the login authentication request initiated by the tSTB, and can identify the identity of the tSTB based on the identification information of the tSTB, so as to allocate matching vSTB resources to the tSTB , To realize the personalized management of different tSTBs, so that it is convenient for the rapid deployment and superposition of services. The service upgrade can be completed in the cloud and take effect in real time. There is no need to consider the compatibility of the new and old STB versions on the existing network. The development environment is unified, which reduces STB software development Testing complexity shortens the STB application software development cycle and reduces R&D costs. On the other hand, the vSTB management platform implements the corresponding management of different tSTB and vSTB resources, which facilitates the support of more services and extends the life cycle of tSTB.
