And the communication channel comprises a first communication channel or a second communication channel. And the screen projection sending equipment establishes a communication channel between the screen projection sending equipment and the screen projection receiving equipment based on the communication mode. For example, based on the communication mode of the IP address, the IP address of the screen projection sending device and the IP address of the screen projection receiving device are obtained, and a communication channel between the screen projection sending device and the screen projection receiving device is established based on the IP address of the screen projection sending device and the IP address of the screen projection receiving device.

Based on the communication channel, the screen projection sending equipment sends the acquired screen projection content to the screen projection receiving equipment so that the screen projection receiving equipment can display the screen projection content. And after receiving the screen projection content, the screen projection receiving equipment displays the screen projection content. For example, the screen projection sending device sends the acquired video to the screen projection receiving device through a communication channel established based on the IP address, so that the screen projection receiving device plays the video.
In the screen-projecting content display method in this embodiment, the connection with the screen-projecting receiving device is automatically established by receiving the infrared connection data sent by the screen-projecting receiving device, and the screen-projecting receiving device does not need to be manually connected with the screen-projecting receiving device by a user, so that the characteristic that infrared rays cannot penetrate through a wall is utilized, the problem that the screen-projecting receiving device is mistakenly connected due to multiple screen-projecting receiving devices in multiple meeting rooms in a specific application scene, such as a meeting scene, is avoided, the screen-projecting sending device of a user who does not participate is prevented from being connected with the screen-projecting receiving device, and the screen-projecting content display efficiency is also improved.

The first communication method corresponding to the first device identifier is a communication method corresponding to the IP address. The first communication channel refers to a communication channel established based on an IP address. The first communication channel may specifically refer to a communication channel established based on a local area network and an IP address.
Specifically, when the infrared connection data includes a first device identifier, and the screen projection sending device determines that the screen projection sending device and the screen projection receiving device are located in the same local area network based on the first device identifier in the infrared connection data, the screen projection sending device determines that the communication mode between the screen projection sending device and the screen projection receiving device is the first communication mode corresponding to the IP address. The screen projection sending device establishes a first communication channel with the screen projection receiving device based on the first communication mode.
In this embodiment, the screen projection sending device splits the infrared connection data, and determines that the infrared connection data includes the first device identifier when the infrared connection data includes an internet protocol broadcast flag (IP cast flag).

The target wireless display protocol is miracast protocol. And the target wireless display protocol communicates based on a second device identification, such as a MAC address. The second communication means corresponds to the target wireless display protocol and to the second device identification. The first device identification is different from the second device identification.
Specifically, when it is determined that the screen projection receiving device and the screen projection sending device are located in different local area networks based on the first device identifier in the infrared connection data, the screen projection sending device and the screen projection receiving device cannot communicate through the first communication channel. And the screen projection sending equipment splits the infrared connection data, and when the split infrared connection data obtain the wireless display protocol mark, the screen projection receiving equipment is determined to support the target wireless display protocol. And when the screen projection receiving equipment is determined to support the target wireless display protocol based on the infrared connection data, determining that the communication mode of the screen projection receiving equipment is the second communication mode corresponding to the target wireless display protocol. And the screen projection sending equipment acquires a second screen projection sending equipment identifier of the screen projection sending equipment and a second identifier in the infrared receiving data, and establishes a second communication channel with the screen projection receiving equipment based on a second communication mode. For example, when it is determined that the screen projection receiving device is located in a different local area network based on the IP address in the infrared receiving device and it is determined that the screen projection receiving device supports the miracast protocol based on the wireless display protocol flag (miracast flag) in the infrared connection data, it is determined that the communication device with the screen projection receiving device is the second communication mode corresponding to the miracast protocol.

In the screen-casting content display method in this embodiment, when the screen-casting receiving device is located in a different local area network from the screen-casting receiving device, data transmission cannot be performed through the first communication channel, so that when the screen-casting receiving device supports the target wireless display protocol, a second communication channel with the screen-casting receiving device is established based on the target wireless display protocol, and screen casting is performed through the second communication channel, which can ensure normal display of screen-casting content.
In one embodiment, determining a communication mode with a screen projection receiving device based on infrared connection data comprises: when it is determined that the screen projection receiving equipment supports the target wireless display protocol based on the infrared connection data, determining that a communication mode with the screen projection receiving equipment is a second communication mode corresponding to the target wireless display protocol; establish and throw the communication channel of screen receiving arrangement based on communication mode, include: and establishing a second communication channel with the screen projection receiving equipment based on a second communication mode.
Specifically, when it is determined that the screen projection receiving device supports the target wireless display protocol based on the infrared connection data, it is determined that the communication mode with the screen projection receiving device is the second communication mode corresponding to the target wireless display protocol. And the screen projection sending equipment establishes a second communication channel with the screen projection receiving equipment based on the second communication mode.
In the screen-casting content display method in this embodiment, when it is determined that the screen-casting receiving device supports the target wireless display protocol based on the infrared connection data, it is determined that the communication mode with the screen-casting receiving device is the second communication mode corresponding to the target wireless display protocol, and another communication mode connected with the screen-casting receiving device is provided, so that normal display of the screen-casting content is ensured.
In one embodiment, the screen-shot content presentation method further comprises: splitting the infrared connection data to obtain a type identifier corresponding to the screen projection receiving equipment; and when the type identifier is the target type identifier, executing the step of determining the communication mode with the screen projection receiving equipment based on the infrared connection data.
The type identifier of the screen projection receiving device refers to a manufacturer identifier of the screen projection receiving device or a brand identifier of the screen projection receiving device. The specific type identification refers to a vendor ID. The target type identifier refers to a type identifier specified by the screen projection sending device, and for example, only the screen projection receiving device corresponding to the type identifier can establish a communication channel.
Specifically, the infrared connection data includes a type identifier of the screen projection receiving device. And the screen projection sending equipment splits the infrared connection data to obtain the type identification corresponding to the screen projection receiving equipment. And when the type identifier is the target type identifier, executing the step of determining the communication mode with the screen projection receiving equipment based on the infrared connection data. And when the type identifier is not the target type identifier, the step of determining the communication mode with the screen projection receiving equipment based on the infrared connection data is not executed, namely the step is directly finished.
In the screen-casting content display method in this embodiment, whether the screen-casting receiving device is a screen-casting receiving device to be subjected to screen casting or not is determined by determining whether the device type identifier is a target type identifier or not, and whether the screen-casting receiving device is supported or not is determined without manually connecting with the screen-casting receiving device.
In one embodiment, the screen-shot content presentation method further includes: splitting the infrared connection data to obtain a target type identifier corresponding to the screen projection receiving equipment; acquiring a target playing parameter corresponding to the target type identifier; and sending the target playing parameters to the screen projection receiving equipment through the communication channel so that the screen projection receiving equipment displays the screen projection content based on the target playing parameters.
The target playing parameter is a parameter for controlling the presentation effect. The target play parameter may refer to a play double speed, a brightness of the projection receiving device, a volume of the projection receiving device, and the like, but is not limited thereto. And the target display parameters are pre-stored in the screen projection sending equipment and are stored corresponding to the type identifications. For example, the volume for type a is 50, the volume for type b is 80, etc. are not limited thereto.

And acquiring a target display parameter corresponding to the target type identifier. And sending the target display parameters to the screen projection receiving equipment through a communication channel so that the screen projection receiving equipment displays the screen projection content based on the target display parameters. For example, the infrared connection data is split to obtain a target type identifier a corresponding to the screen projection receiving device. And the screen projection sending equipment acquires a target display parameter X corresponding to the target type identifier A. And sending the target display parameter X and the screen projection content to the screen projection receiving equipment through a communication channel so that the screen projection receiving equipment displays the screen projection content based on the target display parameter X.
In the screen-casting content display method in this embodiment, because different types of screen-casting receiving devices are different in screen-casting effect, in a screen-casting scene, the target playing parameter corresponding to the target type identifier can be acquired, so that the screen-casting receiving device displays the screen-casting content based on the target playing parameter, and a better display effect can be obtained.
In one embodiment, the screen-shot content presentation method further includes: sending a device binding request to screen projection receiving equipment; establishing a binding relationship between the screen projection receiving equipment and the equipment binding request based on the equipment binding request; and when the infrared connection data is in binding relation with the screen projection receiving device which sends the infrared connection data, executing the step of determining the communication mode with the screen projection receiving device based on the infrared connection data.
The device binding request is used for establishing a binding relationship between the screen projection sending device and the screen projection receiving device. And the binding relationship is stored in the screen projection sending device.
Specifically, the screen projection sending device sends a device binding request to the screen projection receiving device. And after the screen projection receiving equipment agrees with the equipment binding request, the screen projection sending equipment establishes the binding relationship between the screen projection sending equipment and the screen projection receiving equipment based on the equipment binding request. After receiving the infrared connection data sent by the screen projection equipment, when detecting that the infrared connection data is bound with the screen projection receiving equipment sending the infrared connection data, executing a step of determining a communication mode with the screen projection receiving equipment based on the infrared connection data.
In the screen-projecting content display method in the embodiment, since the screen-projecting receiving device itself transmits the infrared connection data, theoretically, as long as the infrared connection data is received, a communication channel can be established with the screen-projecting receiving device; before receiving the infrared connection data sent by the screen projection receiving device, the screen projection receiving device needs to send a device binding request to the screen projection receiving device to establish a binding relationship with the screen projection receiving device, and when the screen projection receiving device is the screen projection receiving device with the binding relationship, a communication channel with the screen projection receiving device needs to be established based on the infrared connection data, so that the situation that a plurality of screen projection sending devices are connected with the screen projection receiving device at the same time can be avoided, and the screen projection content display accuracy is improved.
In one embodiment, the screen projection receiving device is used for sending infrared connection data in a timed mode. The screen projection content display method further comprises the following steps: and when the infrared connection data are not received within the preset time, automatically disconnecting the connection with the screen projection receiving equipment.
The preset duration can be configured according to needs. The preset time length needs to be longer than the timing time length of the screen projection receiving equipment. For example, the screen-projection receiving device sends the infrared connection data once at a timing of 10 seconds, and the preset time period needs to be longer than 10 seconds. And the regularly sent infrared connection data is used for detecting whether the screen projection sending equipment needs to be continuously connected with the screen projection receiving equipment or not.
Specifically, the screen projection receiving device is used for sending infrared connection data at regular time. When the screen projection receiving device and the screen projection sending device are in the same room or conference room, the screen projection sending device can receive the infrared connection data at regular time. And when the screen projection sending equipment does not receive the infrared connection data within the preset time, the screen projection sending equipment is possibly far away from the screen projection receiving equipment and does not need to be connected again, so that the connection with the screen projection receiving equipment is automatically disconnected.
In the screen-casting content display method in this embodiment, the screen-casting receiving device is configured to send the infrared connection data at regular time, and when the infrared connection data is not received within a preset time period, it is indicated that the screen-casting sending device is far away from the screen-casting receiving device, so that the connection with the screen-casting receiving device can be automatically disconnected.
