[0057] The following will be combined with the drawings in the embodiments of this specification to clearly and completely describe the technical solutions in the embodiments of this specification. Obviously, the embodiments described are part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0058] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this specification can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like generally refer to a class and do not limit the number of objects; for example, the first object can be one or more. Furthermore, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the connected objects are in an "or" relationship.

[0059] Currently, satisfying users' demand for interactive screen projection through set-top boxes requires upgrading and improving the physical performance of the set-top boxes and increasing bandwidth speeds. This inevitably increases investment costs for users and operators, and increases the cost of promoting interactive screen projection services.

[0060] In the embodiments of this specification, a management platform can be set up in the cloud, and the management platform can be used to connect the terminal device and the set-top box, so that the screen resources to be cast of the terminal device can be played on the terminal of the set-top box through the management platform. This process relocates the screen casting software to the cloud for operation, reduces the occupation of the set-top box resources by the screen casting operation, and thus supports users to realize mobile phone screen casting on the existing set-top box without the need to update and upgrade the set-top box and without placing high requirements on the user's bandwidth speed. Among them, the management platform can be a virtual processing machine system (abbreviated as vSTB).

[0061] The requirements for the management platform in this specification may include: ① Supporting load balancing for set-top box login to allocate computing resources; ② Managing VR application installation, online / offline, deletion and other management operations; ③ Real-time monitoring of computing server status to ensure that the load can provide computing nodes that can provide services normally.

[0062] See also Figure 1 , a screen projection system provided by an embodiment of the present disclosure, includes: a terminal 101, a management platform 102, a computing server 103, a CDN distributed platform 104, and a public network environment 105. The management platform 102 and computing server 103 can be set up in the cloud, and the computing server 103 is managed by the management platform 102.

[0063] The terminal 101 includes a set-top box and a terminal device. The terminal device may be a user equipment (UE), a mobile device, a terminal device, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc.

[0064] In the above-mentioned screen projection system, the set-top box in the terminal 101 establishes a communication link with the computing server 103 in the cloud management platform 102. By means of scanning a code or other means, the terminal device in the terminal 101 establishes a communication link with the computing server 103, and then the playback resources of the terminal device can be transmitted to the set-top box, so that the set-top box can connect to the CDN distributed platform 104 or the public network environment 105 through a link to load the playback resources for screen projection. This system realizes mobile phone screen projection to the cloud by clouding the screen projection service.

[0065] The following describes in detail the workflow of the management platform of this manual in combination with the screen projection method provided in this manual.

[0066] In an embodiment of the present disclosure, a screen projection method is provided. The method is applied to a management platform located in the cloud. The management platform is used to manage the screen projection services of multiple set-top boxes. Each set-top box can receive playback resources to be projected from at least one terminal device. The method can be implemented by a processor calling computer-readable instructions stored in a memory. Alternatively, the method can be executed by a server in the cloud.

[0067] For ease of description, in one or more embodiments of this specification, the screen projection method may be performed by a cloud-based management platform. The following text describes the method using the management platform as an example. It should be understood that the use of the management platform as the method's execution entity is merely an example and should not be construed as limiting the method.

[0068] Figure 2 A flowchart of a screen projection method according to an embodiment of the present disclosure is shown. Figure 2 As shown, the screen projection method includes:

[0069] Step S202: upon receiving a login request sent by the set-top box, establishing a first communication link between the set-top box and a target computing server in the management platform.

[0070] The set-top box can have basic Android OS computing power. This description does not specify the type and model of the set-top box; this can be determined based on actual circumstances. For example, the set-top box can be a common home model, such as the B860AV1.1. After the set-top box is deployed, default login interface parameters can be set, and management platform information can also be manually configured.

[0071] The terminal of the set-top box can collect the first attribute parameters of the set-top box, including: user account, MAC address, network IP, etc., and can carry the first attribute parameters to access the management system for user authentication and application authentication. After the authentication is passed, the management platform can allocate the idle target computing server to the set-top box according to the load balancing principle of "computing servers with higher idle rates are allocated first". This manual does not specifically limit the method for determining the status information such as the idle rate of the computing server, and it can be determined according to actual conditions. For example, the idle rate of the computing server can be determined based on the number of idle nodes in the computing server.

[0072] After the target computing server is determined, a first communication link between the set-top box and the target computing server may be established as a response to the login request.

[0073] Step S204: Based on the first communication link, the first attribute parameter received from the set-top box is sent to the target computing server, so that the target computing server processes the first attribute parameter to generate a graphic code, and sends the graphic code to the set-top box.

[0074] After the first communication link is established, the set-top box can send the first attribute parameter to the target computing server, so that the target computing server generates a graphic code, such as a QR code or barcode, for the terminal device to scan based on the first attribute parameter. Furthermore, the target computing server can send the generated graphic code to the set-top box, so that the terminal of the set-top box displays the graphic code for the terminal device to scan.

[0075] In one example, the basic service components of a computing server may include: (1) Gateway: responsible for communication and forwarding between other modules in the computing server (such as cloud display modules, containers, etc.) and external devices (including management platform systems and terminal devices); (2) Cloud display module: responsible for communication with terminal devices, conveying set-top box messages to containers, and pushing encoded streaming media to set-top boxes; accessing management platform system communications, maintaining computing nodes and container heartbeats (i.e., working status) and reporting; (3) Operating system: deploying containers, providing computing power services for the management platform, supporting application startup, shutdown, and resource decoding, etc.; (4) Computing node management module: implementing node task execution, calling underlying components, and docking with the management platform.

[0076] Figure 3 A flow chart of the internal structure of a computing server is shown. In one example, after the first communication link is established, Figure 3 The cloud display module in the system starts the screen projection application APP through the control panel agent module (corresponding to step 303), and synchronizes the attribute parameters of the set-top box and the container terminal to generate QR code information for the mobile phone to scan. The parameters are sent to the mobile phone terminal through the cloud display module and the gateway (corresponding to steps 404 and 403), and the QR code is decrypted by the set-top box and displayed to the user (corresponding to step 301).

[0077] Step S206: upon receiving information indicating that the terminal device has scanned the graphic code of the set-top box, a second communication link is established between the terminal device and the target computing server.

[0078] After the set-top box terminal displays the graphic code, the user can use the terminal device to scan the graphic code, and then generate information and return it to the management platform. The management platform establishes a second communication link based on the received information. The information generated by the terminal device can be the information contained in the graphic code.

[0079] Step S208: Upon receiving a screen projection request for a screen projection resource sent by the terminal device through the second communication link, the screen projection resource is transferred from the terminal device to the set-top box through the first communication link and the second communication link, so that the set-top box performs screen projection processing based on the screen projection resource.

[0080] Through steps S202-S206, a first communication link and a second communication link are established between the terminal device and the set-top box based on the cloud-based management platform. Furthermore, when a user needs to cast a screen, they can use the terminal device to send a screen casting request to the management platform. The screen casting resources corresponding to the screen casting request are transferred from the terminal device to the set-top box via the first communication link and the second communication link, thereby implementing the screen casting operation on the set-top box. The communication protocols of the first communication link and the second communication link can be the same.

[0081] In the embodiments of this specification, a cloud-based management platform establishes a first communication link and a second communication link connecting a terminal device and a set-top box. The first and second communication links enable the terminal device's screen projection resources to be projected through the set-top box. This process, through the cloud-based management platform, centrally manages the terminal device's screen projection operations based on the set-top box, enabling cloud-based screen projection services. This reduces the memory and CPU pressure on the set-top box and relieves the limitations imposed by terminal device screen projection on the set-top box configuration. This can improve the set-top box user experience and meet users' demand for value-added services from the set-top box.

[0082] In one example, the computing server can adapt to the container scenario, access the k8s (Kubernetes) cluster, and support basic operations such as the creation, operation, and deletion of virtual platforms such as POD containers. In one implementation, the management platform includes multiple computing servers, and when a login request is received from a set-top box, a first communication link is established between the set-top box and a target computing server in the management platform, including:

[0083] Upon receiving the login request, determining a target container based on the plurality of computing servers and status information of containers in the computing servers;

[0084] A first communication link is established between the set-top box and a gateway of a computing server corresponding to the target container.

[0085] Specifically, the management platform can be built based on distributed computing servers. Each computing server can have multiple computing nodes, and each computing node can contain multiple containers. Specific container types can be selected as computing nodes. Since set-top boxes typically have Android OS computing power, Android containers can be selected as computing nodes to facilitate interaction between the set-top boxes and the management platform.

[0086] Upon receiving a login request from a set-top box, the state information of each computing server and the state information of the containers in the computing server can be determined in real time, thereby determining a target container for providing computing services. In one implementation, upon receiving the login request, determining the target container based on the state information of the plurality of computing servers and the containers in the computing servers includes:

[0087] Upon receiving the login request, determining a target computing server from the plurality of computing servers based on status information of the plurality of computing servers;

[0088] Determining a target computing node from the target computing server based on status information of each computing node in the target computing server;

[0089] The target container is determined from the target computing node based on status information of each container in the target computing node.

[0090] In one example, a scheduled "heartbeat reporting" function can be configured for compute servers. This means that the compute servers can periodically report the current operating status of the compute nodes and their containers to the management node. During load balancing, the compute servers can authenticate and return idle container information. This allows for real-time updates of the operating status of nodes and containers on each compute server within the management platform.

[0091] Specifically, the content reported by the "heartbeat reporting" timing function may include: ① The process status of the computing node and the information of the computing server where the computing node is registered. The computing node can be labeled "whether it is functioning normally"; ② The status of all containers under the computing node to limit the allocation of abnormal PODs (the structure of the encapsulated container). The computing node can be labeled "whether the capacity is idle" to limit the allocation of abnormal PODs (the structure of the encapsulated container). When load balancing, the management platform determines whether the current node has idle computing power terminals (i.e., containers) for user access by querying the service process. Each node will return the node self-test results to the management platform.

[0092] When a login request is received, a computing server with a higher computing node idle rate can be first determined as the target computing server from the content reported by the "heartbeat reporting" timing function; then a computing node with a higher idle rate is determined in the target computing server as the target computing node; further, an idle container is determined in the target computing node as the target container. In order to enable data to be transmitted between the set-top box and the target container, the gateway corresponding to the target container is used as the target gateway, and a first communication link is established through the target gateway.

[0093] After determining the target container, information related to the target container can be returned to the set-top box to establish the first communication link. The returned information may include, but is not limited to: ① the name, network address, and port of the target container; ② the external network address and port of the target gateway; and ③ the token authentication information used when establishing the first communication link. In one example, the token authentication information can be updated once the user completes a login and logout cycle.

[0094] Furthermore, based on the returned information, the set-top box can initiate a communication request to the gateway corresponding to the target container. After receiving the request, the gateway can obtain the target container name, network IP and port while parsing the first attribute parameter, and then establish a link with the cloud display module matching the target container, and forward the login request to the cloud display module; the cloud display module can verify the token value carried in the login request, and allow the link to be established if the verification is passed, otherwise disconnect the direct connection between the set-top box and the gateway corresponding to the target container.

[0095] In this embodiment, a target container is determined based on the status information of the compute server and container, and a first communication link is established between the set-top box and the gateway of the compute server corresponding to the target container. This process establishes the first communication link between the set-top box and the target compute server in the management platform, providing a foundation for migrating screen projection software and functions to the cloud.

[0096] In one implementation, upon receiving information that the terminal device scans the graphic code of the set-top box, establishing a second communication link between the terminal device and the target computing server includes:

[0097] Upon receiving the information sent by the terminal device, a second communication link is established between the terminal device and a gateway of a computing server corresponding to the target container based on a second attribute parameter of the target container in the information. The terminal device obtains the information by scanning a graphic code of the set-top box, and the target container generates a graphic code based on the first attribute parameter and the second attribute parameter.

[0098] The second attribute parameter is an attribute parameter of the target container, which may include the container name, network IP address, and port number. After determining the target container, to establish a communication link between the terminal device and the set-top box, in one example, the target container may generate a graphic code based on the first attribute parameter and the second attribute parameter. The terminal device then scans the graphic code to establish a second communication link between the terminal device and the gateway of the computing server corresponding to the target container. In this case, the first communication link and the second communication link constitute the communication link between the terminal device and the set-top box.

[0099] exist Figure 3 In the process, the cloud display module starts the screen projection application APP through the control panel proxy module (corresponding to step 303), synchronizes the attribute parameters of the set-top box and the target container, generates a QR code information for the mobile phone to scan, and passes through the cloud display module and the gateway (corresponding to steps 404 and 403), sends the parameters to the set-top box (corresponding to step 301), and decrypts and displays the QR code through the terminal of the set-top box. The user's mobile phone terminal scans the QR code displayed by the set-top box to obtain the target container information and token authentication information, and then successfully establishes a link with the gateway corresponding to the target container. Among them, when the mobile phone scans the QR code to access the target container, the cloud display module can determine the target container to be connected to the mobile phone terminal through the token authentication information.

[0100] In one implementation, upon receiving a screen projection request for a screen projection resource sent by the terminal device through the second communication link, transmitting the screen projection resource from the terminal device to the set-top box through the first communication link and the second communication link, so that the set-top box performs screen projection processing based on the screen projection resource, includes:

[0101] Upon receiving a request for a screen projection resource sent by the terminal device through the second communication link, receiving a network link of the screen projection resource sent by the terminal device through the second communication link;

[0102] The network link is sent to the set-top box through the first communication link, so that the set-top box projects the screen projection resource through the network link.

[0103] Specifically, the process of screen projection through the link between the set-top box and the terminal device can be: first, the screen projection resources to be projected by the terminal device are sent to the management platform through the second communication link, and the management platform then forwards the screen projection resources to the terminal of the set-top box through the first communication link.

[0104] The following combination Figure 3 Analyze the specific process in the computing node during the screen projection process:

[0105] like Figure 3As shown, the user operates the mobile phone terminal to perform interactive screen projection. First, the user scans the assistant application or applet to upload the URL link of the projection to the gateway (corresponding to step 402), and sends it to the built-in control panel agent module through the cloud display module (corresponding to step 403), and further sends the URL link to the projection application APP through the internal designated port in a transparent manner. The projection application APP calls the interface of the player in the container, so that the URL link is intercepted by the playback agent module (corresponding to step 405), and the URL link to be played is converted according to the configuration information. After the conversion is successful, the converted URL link is sent to the set-top box through the gateway (corresponding to steps 406 and 301).

[0106] Typically, a set-top box accesses a link to obtain the resource corresponding to the link, and then projects the resource. In one implementation, sending the network link to the set-top box via the first communication link so that the set-top box projects the projection resource via the network link includes:

[0107] In a case where the network link is a link that the set-top box can directly access, sending the network link to the set-top box through the first communication link, so that the set-top box projects the screen projection resource through the network link;

[0108] In the case that the network link is a link that the set-top box cannot directly access, the target computing server is used to convert the network link, and the converted network link is sent to the set-top box through the first communication link, so that the set-top box projects the screen projection resource through the converted network link.

[0109] Different bureaus have different requirements for set-top boxes. For example, open bureaus allow set-top boxes to access public or private network resources, while closed bureaus require set-top boxes to only access resources on a closed, specific private network. In one example, upon receiving a network link (such as a URL link) sent by a terminal device, it is possible to first determine whether the network link is a link that the set-top box can directly access. If the network link is not directly accessible, the network link can be converted (for example, by adding a CDN parameter item) to a link that the set-top box can directly access. Whether the network link can be directly accessed by the set-top box can be determined based on the bureau to which the network link belongs.

[0110] Furthermore, the set-top box can call the local player interface according to the address corresponding to the received network link, go to the specified CDN address or public network address to load resources, thereby realizing the playback of the projection resources on the set-top box.

[0111] In the embodiments of this specification, the screen projection service is cloud-based based on network link conversion through the first communication link and the second communication link, so that the resources of different terminal devices can be projected on the set-top box, thereby improving the robustness of the screen projection method and reducing the promotion and use costs of the screen projection method.

[0112] See also Figure 4 , is a specific implementation of the screen projection method of the embodiment of this specification, which is based on Figure 1 Based on the screen projection system in , in this implementation, the specific process of the screen projection method is as follows:

[0113] Step S401: The set-top box logs in to the access management platform. Specifically, the set-top box is a cloud-based set-top box (tSTB). The management platform is a virtual processing system (vSTB). Based on the login access request, the management platform allocates a target container to the set-top box.

[0114] Step S402: The set-top box establishes a communication link with a gateway and authenticates user information. Specifically, the gateway is the gateway of the computing server corresponding to the target container. The user information is the attribute data of the set-top box. The link between the set-top box and the gateway is a first communication link.

[0115] Step S403: Synchronize terminal data and generate a QR code. Specifically, the terminal data includes attribute data of the set-top box and the target container. The QR code generated in this process will be sent to the terminal of the set-top box based on the first communication link.

[0116] Step S404: The terminal device scans successfully and establishes a communication link with the gateway. Specifically, if the terminal device scans the QR code successfully, a second communication link will be established with the gateway of the target container.

[0117] Step S405: Transmit the screen casting playback URL, and the built-in playback proxy module converts the playback link. Specifically, based on the second communication link, the terminal device transmits the URL link to be cast and played to the target container, and the target container uses the built-in playback proxy module to convert the URL link.

[0118] Step S406: The converted URL is transmitted back to the client, which then calls the player to load the CDN or public network resource. Specifically, based on the first communication link, the target container transmits the converted URL link back to the set-top box. The set-top box then calls the local player interface to load the resource from the CDN or public network address specified by the URL link, thereby enabling the projection of the screen resource to the set-top box terminal.

[0119] In the embodiments of this specification, a cloud-based management platform establishes a first communication link and a second communication link connecting a terminal device and a set-top box. The first and second communication links enable the terminal device's screen projection resources to be projected through the set-top box. This process, through the cloud-based management platform, centrally manages the terminal device's screen projection operations based on the set-top box, enabling cloud-based screen projection services. This reduces the memory and CPU pressure on the set-top box and relieves the limitations imposed by terminal device screen projection on the set-top box configuration. This can improve the set-top box user experience and meet users' demand for value-added services from the set-top box.

[0167] The foregoing description describes specific embodiments of the present application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims can be performed in an order different from that described in the embodiments and still achieve the desired results. Furthermore, the processes depicted in the accompanying drawings do not necessarily require the specific order shown or the sequential order to achieve the desired results. In certain embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0168] In the 1990s, technological improvements could be clearly distinguished as either hardware improvements (for example, improvements to circuit structures such as diodes, transistors, and switches) or software improvements (improvements to process flows). However, with the advancement of technology, many process flow improvements today can now be considered direct improvements to hardware circuit structures. Designers almost always create the corresponding hardware circuit structure by programming the improved process flow into the hardware circuit. Therefore, it cannot be said that a process flow improvement cannot be implemented using hardware modules. For example, a programmable logic device (PLD), such as a field programmable gate array (FPGA), is an integrated circuit whose logical function is determined by user programming. Designers can "integrate" a digital system on a PLD by programming it themselves, without having to hire a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly done using "logic compiler" software. This is similar to the software compiler used when developing programs. Before compilation, the original code must also be written in a specific programming language, called a hardware description language (HDL). There is not just one HDL, but many, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art will also understand that by simply programming the method flow in one of these hardware description languages ​​and then programming it into an integrated circuit, a hardware circuit that implements the logic method flow can be easily obtained.

[0169] The controller can be implemented in any suitable manner. For example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also know that in addition to implementing the controller in a purely computer-readable program code format, the controller can be implemented in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers by logically programming the method steps. Therefore, such a controller can be considered a hardware component, and the devices included therein for implementing various functions can also be considered as structures within the hardware component. Or even, the devices for implementing various functions can be considered as both software modules that implement the method and structures within the hardware component.
