Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
First, terms related to one or more embodiments of the present application will be explained.
Screen throwing: the picture of one terminal is projected onto the display device of the other terminal.
DMC, an abbreviation of Digital Media Controller (digital media controller), can search and control DMR to play the content provided by DMS, i.e. control DMR interaction with DMS, such as mobile phone APP.
DMR, an abbreviation for Digital Media Renderer (digital media renderer), plays back DMS provided content, e.g. TV side APP.
The DMS, an abbreviation for Digital Media Server (digital media server), mainly functions as a provider of media content, providing content playback for DMP/DMR, which media content is provided by the DMS can be controlled.
DMP, an abbreviation for Digital Media Player (digital media player), can search and play the content of DMS, which acts as dmr+dmc.
OTT service: generally means that the content or service is built on top of the underlying telecommunication service so that no additional support is required by the network operator. This concept early refers to the distribution of audio and video content, and later gradually encompasses various internet-based content and services. Typical examples are cloud-view aurora, cloud-view small televisions, and the like.
DLNA is one of the most widely used projection protocols, which is an integration of various technologies and is dedicated to the construction of home media sharing. DLNA contains a variety of network protocols, such as http, https, UPnP, etc., of which the universal plug and play protocol-UPnP (Universal Plug and Play) is an important component.
The Upnp architecture divides roles in a home network into three types: control points, devices, and services. Communication between them is achieved mainly by HTTP technology. The specification information of the equipment and the related services is published to other nodes in an XML mode. The relationship of the roles of UPnP is shown in fig. 1.
The basic concept of each role of UPnP is as follows:
1. root device/device, i.e. hardware device, such as computer, television box, etc. One device may provide a plurality of services. However, the interior of a household appliance generally includes a plurality of devices having different functions, and thus a device aggregate formed by integrating a plurality of devices is called a root device.
2. The functional services that the device can provide. The method is divided into a control service, an event service and a display service. The service is the smallest controllable unit (action and state) in the Upnp system.
3. Control points. I.e. the control device, may discover and control other devices. Such as controlling video playback, pausing, etc., of other devices. In the process of DLNA screen projection, the Android device plays a role of a control point, initializes and configures connection between the DMS and the DMR device, and does not directly participate in real content transmission, wherein the content transmission is completed by the DMS and the DMR.
The DLNA screen-throwing flow is as follows: network transmission of DLNA is started by device discovery. First, a new Control Point (Control Point) joins the lan, and then the Control Point starts searching for available devices in the lan. When the control point starts searching, it will send a search request message of a specific format from the UDP port. If a usable device is found, a message is received with url pointing to a device service and information description document, typically in xml format. By parsing the url field, it is possible to see the basic information of the device, such as name, model, etc., and the supported service actions, such as volume control, playing specific video, cutting, etc. The developer can send request information with a specified format according to the request parameters specified in the protocol document, and when realizing specific service functions, such as screen projection, the video url is transmitted to the DMR device through the SetAVTransportURI information, so that the video url can start playing.
The inventor of the application finds that when the existing screen-throwing method does not start the OTT service of the third party, the screen-throwing service of the DMR equipment can only be pulled up when the screen is thrown. When the screen is projected based on the DLNA protocol, if the third party OTT service in the DMR equipment is not started, the DMC equipment can only search the signal sent by the DMR equipment, and at the moment, the screen is projected, and the screen projection service of the DMR equipment can only be pulled up, so that some customized function services provided by the third party OTT service can not be used. In order to solve the above problems, the inventors of the present application have proposed a screen projection scheme of the present application through creative work.
Fig. 2 shows a signaling diagram of a screen projection method according to one embodiment in the present application. As shown in fig. 2, the method comprises the steps of:
in step S201, the DMR device broadcasts a DMR device signal according to an opening operation triggered by the user.
Specifically, when the user wants to put on the screen to play the corresponding data, the user needs to open the DMR device, and at this time, the DMR device broadcasts a DMR device signal in the local area network, for example, in the wifi local area network, where the DMR device signal includes: vendor name and preset field; the vendor name is used for the DMC device to identify whether the DMR device is a partner vendor, and the preset field is used for indicating whether the capability of partner to pull up the third party OTT service exists in the DMR device. In addition, the DMR device signal also includes device basic information, such as a name, a model, etc., for the DMC device to know which DMR device to screen.
In specific implementation, the following fields may be added to the DLNA device information protocol: the vendor name field and the preset field, for example, when the field value of the preset field can be defined to be 1, indicate that the DMR device has the capability of automatically pulling up the OTT service of the third party; when the field value of the preset field is 0, this indicates that the DMR device does not have the capability of automatically pulling up the OTT service of the third party, which is only illustrated herein, and does not have any limiting effect.
Step S202, DMC equipment searches for DMR equipment signals according to screen throwing operation triggered by a user.
When the user wants to play the screen throwing data on the large screen, the user can trigger the screen throwing operation, specifically, a screen throwing button is arranged on a play page of the screen throwing data of the DMC device, the user triggers the screen throwing button to be regarded as triggering the screen throwing operation, for example, when the user wants to throw a video picture played by a video APP of a mobile phone to a television, the user can click a 'TV' button to be regarded as triggering the screen throwing operation, the DMC device searches for a DMR device signal according to the screen throwing operation triggered by the user, for example, the DMC device sends a search request message in a specific format through a UDP port to find the DMR device in a local area network, and if the DMR device is found to be available, the DMC device can receive a response message with the DMR device signal returned by the UDP port.
In step S203, the DMC device determines whether the DMR device signal meets a preset condition, and if yes, sends a screen projection request carrying a screen projection data URL address, a screen projection channel identifier and an DMC device IP address to the DMR device.
After searching the DMR device signal, the DMC device also needs to further judge the DMR device signal, mainly judges whether the DMR device signal meets the preset condition, and determines which information is carried in the screen-throwing request sent to the DMR device by making corresponding judgment.
In specific implementation, the information cloud control capability of the cooperators is newly added on the DMC device side, which manufacturers need to cooperate with can be controlled in real time, for example, a cooperator list is preset, the cooperator names are recorded in the cooperator list, after the DMC device searches the DMR device signal, the manufacturer names in the DMR device signal are matched with the manufacturer names in the pre-set manufacturer list, if so, whether the field values of the pre-set fields are pre-set values is further judged, and if so, whether the field values of the pre-set fields are pre-set values is mainly for judging whether the DMR device has the capability of pulling up the third party OTT service or not, and if so, the DMR device signal is determined to meet the pre-set conditions.
And under the condition that the DMR equipment signal meets the preset condition, the DMC equipment sends a screen projection request carrying the screen projection data URL address, the screen projection channel identifier and the IP address of the DMC equipment to the DMR equipment. Wherein the screen-drop channel identification is used to identify which company the screen-drop service of the DMC device belongs to. The URL address of the screen throwing data is an acquisition address of the screen throwing data, and the screen throwing data can be acquired according to the address to be played. The IP address of the DMC device is used for the third party OTT service to establish connection with the DMC device so as to facilitate the direct interaction of the DMC with the third party OTT service. The screen projection data may be video, audio, word documents, etc., which are only examples, and other data that may be used for screen projection are all within the scope of the present application.
In order to improve safety, the screen-throwing data URL address can be encrypted, and the encrypted screen-throwing data URL address is sent to the DMR equipment.
And if the DMR equipment signal does not meet the preset condition, for example, the manufacturer name is not matched with the manufacturer name in the preset manufacturer list, and/or the field value of the preset field is not the preset value, ordinary screen projection is performed, for example, a screen projection request carrying a screen projection data URL address is sent to the DMR equipment, after the screen projection request is received, the DMR equipment projects the screen to the screen projection service of the DMR equipment, and the method is ended.
In an optional implementation manner of the present application, a switch for enabling the third party OTT service may be further provided, and the user determines whether to open the switch according to the actual use requirement of the switch, if the switch is opened, the customization capability of the third party OTT service is enabled, and if the switch is not opened, the customization capability of the third party OTT service is not enabled.
After the DMC device searches the DMR device signal, whether customized capability of cooperative pull-up of the third party OTT service is started can be judged first, and if yes, whether the DMR device signal meets the preset condition is further judged.
In step S204, the DMR device receives the screen-throwing request sent by the DMC device, starts the corresponding third party OTT service according to the screen-throwing channel identifier, and transparently transmits the screen-throwing data URL address and the IP address of the DMC device to the third party OTT service, so that the third party OTT service plays the screen-throwing data according to the screen-throwing data URL address and sends a connection establishment request to the DMC device based on the IP address of the DMC device.
The DMR equipment receives a screen throwing request sent by the DMC equipment, wherein the DMR equipment does not consume the URL address of the screen throwing data after receiving the screen throwing request, but tries to pull up the third party OTT service corresponding to the screen throwing channel identifier, and directly transmits the URL address of the screen throwing data to the third party OTT service, and the third party OTT service plays the screen throwing data according to the URL address of the received screen throwing data.
It should be noted that, the encryption and decryption modes may be pre-agreed by the DMC device and the third party OTT service, the DMC device encrypts the screen-throwing data URL address according to the agreed encryption mode, and after the DMC device sends the encrypted screen-throwing data URL address to the DMR device, the third party OTT service may decrypt the screen-throwing data URL address by utilizing the agreed decryption mode after receiving the encrypted screen-throwing data URL address that is transmitted by the DMR device.
In addition, the DMR device also transmits the IP address of the DMC device to the third party OTT service, and the third party OTT service finds the DMC device in the local area network based on the IP address of the DMC device, and sends a connection establishment request to the DMC device through a private protocol.
In step S205, the DMC device receives a connection establishment request sent by the third party OTT service based on the IP address of the DMC device, and establishes a connection with the third party OTT service according to the connection establishment request. The connection establishment request carries a screen throwing data URL address.
The DMC equipment receives a connection establishment request sent by a third party OTT service based on an IP address of the DMC equipment, wherein the connection establishment request carries a screen throwing data URL address which is used for the DMC equipment to verify whether the screen throwing data URL address is consistent with screen throwing data requested by a user. After receiving the request, the DMC equipment establishes connection with the third party OTT service according to the connection establishment request.
In step S206, the DMC device performs verification on the URL address of the screen-throwing data, and if the verification is passed, the DMC device sends a preset function service request to the third party OTT service by using the established connection, so that the third party OTT service can respond to the preset function service request.
When a connection is requested to be established between the third-party OTT service and the DMC equipment, the connection request carries a screen-throwing data URL address for verification by the DMC equipment, so as to verify whether the third-party OTT service and the DMC equipment are the same screen-throwing data, wherein the screen-throwing data URL address sent by the third-party OTT service is matched with the screen-throwing data URL address sent to the DMR equipment by the DMC equipment, and if the screen-throwing data URL address is consistent with the screen-throwing data URL address sent by the DMC equipment, the verification is passed; if not, the verification fails.
Under the condition that verification is passed, the DMC device can send a preset function service to the third party OTT service by utilizing the connection established between the DMC device and the third party OTT service so that the third party OTT service can respond to the preset function service.
The user can enjoy the exclusive function of the third party OTT service to the DMC device, such as barrage display and higher definition display, specifically, the user wants to throw a barrage for display, the barrage display operation can be triggered at the DMC device, for example, a barrage display switch is turned on, the DMC device sends a barrage display request to the third party OTT service by using the connection established with the third party OTT service, and the third party OTT service displays barrage information in response to the barrage display request; and sending an update request carrying updated definition information or tone quality information to the third party OTT service by using the connection established with the third party OTT service, so that the third party OTT service updates the definition of the screen throwing data according to the updated definition information or updates the tone quality of the screen throwing data according to the tone quality information, for example, when a user finds that the definition of a video picture is lower and influences user watching experience, or the tone quality of an audio file is lower, the definition of the video picture can be increased, or the tone quality of the audio file can be increased, the user can select the updated definition or tone quality at the DMC device, and the DMC device sends an update request carrying the updated definition information or tone quality information to the third party OTT service by using the connection established with the third party OTT service, and the third party OTT service updates the definition of the screen throwing data according to the updated definition information or updates the tone quality of the screen throwing data according to the tone quality information. In addition, bullet screen shape control services, such as profiled bullet screen display, can also be implemented.
After connection with the third party OTT service is established, the DMC equipment can directly interact with the third party OTT service, transfer of the DMR equipment is not needed any more, control of the DMR equipment is achieved by the DMC equipment, and screen-throwing link closed loop is completed.
In an optional embodiment of the present application, before the corresponding third party OTT service is started according to the screen-throwing channel identifier, the method further includes:
