For example, when the second electronic device 200 drops the currently displayed content to the first electronic device 100, the second electronic device 200 transmits the audio stream and the video stream to the first electronic device 100 because the second electronic device 200 confirms that the first electronic device 100 has the audio-video playback capability.
In some embodiments, assuming that the second EDID records the display capability information of the first display screen 1001, but does not record the audio capability information of the first audio module 1002, when the first electronic device 100 successfully negotiates with the second electronic device 200 based on the second EDID, the second electronic device 200 may confirm that the first electronic device 100 is video-capable and not audio-capable, and the second electronic device 200 may transmit the video stream to the first electronic device 100 in a wired manner or a wireless manner. For example, when the second electronic device 200 drops the currently displayed content to the first electronic device 100, since the second electronic device 200 confirms that the first electronic device 100 has video playing capability and does not have audio playing capability, the second electronic device 200 transmits only the video stream to the first electronic device 100, that is, the video stream of the second electronic device 200 is separated from the audio stream, and the audio stream is not transmitted.

A schematic system architecture of a multi-device wired-based communication negotiation according to an embodiment of the present invention is described below with reference to fig. 5a and 5 b.
The embodiment includes a first electronic device 100 and a second electronic device 200. The following description will take the example that the first electronic device 100 and the second electronic device 200 each include a USB interface, an HDMI interface, and a DP interface. The first electronic device 100 and the second electronic device 200 may be connected by a USB connection line, an HDMI connection line, a DP connection line, or a connection line such as a USB-to-HDMI line, a DP-to-HDMI line.
As shown in fig. 5a, the first electronic device 100 may include a first memory 1004 for storing a first EDID and a third memory 1006 for storing a second EDID.

TABLE 1
/>
The first electronic device 100 may include two modes of operation (hereinafter referred to as a first mode and a second mode for convenience of distinguishing the description). When the first electronic device 100 is in the first mode, the first electronic device may obtain the first EDID in response to the negotiation request sent by the second electronic device 200 and send the first EDID to the second electronic device 200 to perform communication negotiation with the second electronic device 200, where the negotiation information sent by the first electronic device 100 to the second electronic device 200 includes display capability information of the first display screen 1001 and audio capability information of the first audio module 1002; when the first electronic device 100 is in the second mode, the first electronic device may obtain the second EDID in response to the negotiation request sent by the second electronic device 200 and send the second EDID to the second electronic device 200 to perform communication negotiation with the second electronic device 200, the negotiation information transmitted by the first electronic device 100 to the second electronic device 200 only includes the display capability information of the first display screen 1001, and the second electronic device 200 may determine that the first electronic device 100 does not have the audio playing capability based on the negotiation information, that is, the second electronic device 200 will not send the audio stream to the first electronic device 100.
The first electronic device 100 is set to the first mode by default when shipped from the factory. The first electronic device 100 may switch between a first mode and a second mode. For example, when the first electronic device 100 receives the first operation instruction in the first mode, the first electronic device 100 is switched from the first mode to the second mode, and when the first electronic device 100 receives the second operation instruction in the second mode, the first electronic device 100 is switched from the second mode to the first mode. The first operation instruction and the second operation instruction may be instructions triggered by a user operating an entity key of the first electronic device 100, or by a touch operation on the first display screen 1001, or by an operation on a remote controller paired with the first electronic device 100.
For example, in fig. 5a, taking the first electronic device 100 as a display including an audio device, the first processor 1003 as a display driving chip, the second electronic device 200 as a notebook computer, the first electronic device 100 and the second electronic device 200 are connected by a DP to HDMI line as an example. The user may enter an on-screen display (OSD) by manipulating a physical key on the display, and the OSD may include a menu interface for making the first mode and the second mode selections. The user may select the first mode or the second mode in the OSD. When the first display screen 1001 is a touch screen, the user may also perform a touch operation on the first display screen 1001 to enter an OSD to perform selection of the first mode or the second mode. The first mode is used for indicating that the first electronic device 100 can receive the audio stream and the video stream, and the second mode is used for indicating that the first electronic device 100 can receive one of the audio stream and the video stream.
If the second mode indicates that the first electronic device 100 can only receive the audio stream, it does not mean that the first electronic device 100 does not have the processing capability of the video stream, the first electronic device 100 may include a hardware module for processing and playing the video stream, but is not visible with respect to the second electronic device 200 at the software level. If the second mode indicates that the first electronic device 100 can only receive the video stream, it does not mean that the first electronic device 100 does not have the processing capability of the audio stream, and the first electronic device 100 may also include a hardware module for processing and playing the audio stream, which is not visible with respect to the second electronic device 200 at the software level.
After the user selects the first mode, the display driver chip may read the first EDID from the first memory 1004 in response to the negotiation request sent by the notebook computer, and transmit the first EDID to the notebook computer through the DP to HDMI line, so as to perform communication negotiation with the notebook computer. After the communication negotiation between the notebook computer and the display is successful, the application scene, such as a video projection playing scene, of the notebook computer for transmitting the video stream and the audio stream to the display can be achieved. After the user selects the second mode, the display driver chip may read the second EDID from the third memory 1006 in response to the negotiation request sent by the notebook computer, and transmit the second EDID to the notebook computer through the DP-HDMI line, so as to perform communication negotiation with the notebook computer. After the communication negotiation between the notebook computer and the display is successful, the application scene that the notebook computer only transmits the video stream to the display and does not transmit the audio stream to the display can be achieved, the interference between the audio equipment of the notebook computer and the audio equipment of the display can be avoided, or the scene requirement that a user only expects to throw a picture to the display and the sound is not transmitted to the display can be met.
After the display successfully negotiates with the notebook computer based on the first EDID, if the user operates a physical key on the display to enter the OSD and selects the second mode in the OSD, the screen-on connection between the display and the notebook computer will be disconnected, the notebook computer may resend the negotiation request to the display, and the display driver chip may respond to the negotiation request sent by the notebook computer, read the second EDID from the third memory 1006 and send the second EDID to the notebook computer to carry out the communication negotiation again with the notebook computer. After the display successfully negotiates with the notebook computer based on the second EDID, if the user operates a physical key on the display to enter the OSD and selects the first mode in the OSD, the screen-on connection between the display and the notebook computer will be disconnected, the notebook computer may resend the negotiation request to the display, and the display driver chip may respond to the negotiation request sent by the notebook computer, read the first EDID from the first memory 1004 and send the first EDID to the notebook computer to carry out the communication negotiation again with the notebook computer.
For example, as shown in fig. 5b, the first electronic device 100 is a smart screen, the first processor 1003 is an SOC chip, the second electronic device 200 is a notebook computer, and the first electronic device 100 and the second electronic device 200 are connected through an HDMI line. The user can enter the setting interface by operating an entity key on the intelligent screen or a remote controller matched with the intelligent screen, and the first mode or the second mode is selected in the setting interface. When the first display screen 1001 is a touch screen, the user may also enter the setting interface by performing a touch operation on the first display screen 1001, so as to select the first mode or the second mode. After the user selects the first mode, the SOC chip may read the first EDID from the first memory 1004 in response to a negotiation request sent by the notebook computer, and transmit the first EDID to the notebook computer through the HDMI line to perform a communication negotiation with the notebook computer. After the communication negotiation between the notebook computer and the intelligent screen is successful, the application scene that the notebook computer transmits the video stream and the audio stream to the intelligent screen, such as a video projection screen playing scene, can be achieved; after the user selects the second mode, the SOC chip may read the second EDID from the third memory 1006 in response to the negotiation request sent by the notebook computer, and transmit the second EDID to the notebook computer through the HDMI line to perform a communication negotiation with the notebook computer. After the communication negotiation between the notebook computer and the intelligent screen is successful, the application scene that the notebook computer only transmits the video stream to the intelligent screen, but not the audio stream to the intelligent screen can be achieved, the interference between the audio equipment of the notebook computer and the audio equipment of the intelligent screen can be avoided, or the scene requirement that the user only expects to throw the picture to the intelligent screen, but the sound is not transmitted to the intelligent screen can be met.
As shown in fig. 6a, taking the first electronic device 100 as a smart screen and the second electronic device 200 as a notebook computer, the first electronic device 100 and the second electronic device 200 are connected by an HDMI line. When the first electronic device 100 successfully communicates with the second electronic device 200 based on the first EDID, the sound setup interface of the second electronic device 200 may present the audio playback device L1 (e.g., the speaker in the first audio module 1002) of the first electronic device 100 and the audio playback device L2 (e.g., the speaker in the second audio module 2002) of the second electronic device 200.
As shown in fig. 6b, taking the first electronic device 100 as a smart screen and the second electronic device 200 as a notebook computer, the first electronic device 100 and the second electronic device 200 are connected through an HDMI cable, and the second EDID records the display capability information of the first display screen 1001, but does not record the audio capability information of the first audio module 1002. When the first electronic device 100 successfully communicates with the second electronic device 200 based on the second EDID, the sound setting interface of the second electronic device 200 presents only the audio playback device of the second electronic device 200, i.e., the audio playback device of the first electronic device 100 is not visible on the second electronic device 200.
In other embodiments, if the second EDID records the audio capability information of the first audio module 1002, the display capability information of the first display screen 1001 is not recorded. When the first electronic device 100 successfully communicates with the second electronic device 200 based on the second EDID, the display setting interface of the second electronic device 200 presents only the display device of the second electronic device 200, i.e. the display device of the first electronic device 100 is not visible on the second electronic device 200.

After the communication negotiation between the notebook computer and the intelligent screen is successful, the application scene that the notebook computer only transmits the video stream to the intelligent screen, but not the audio stream to the intelligent screen can be achieved, the interference between the audio equipment of the notebook computer and the audio equipment of the intelligent screen can be avoided, or the scene requirement that the user only expects to throw the picture to the intelligent screen, but the sound is not transmitted to the intelligent screen can be met.
For example, as shown in fig. 7b, the first electronic device 100 is a display including an audio device, the first processor 1003 includes a display driver chip and an SOC chip, the second electronic device 200 is a notebook computer, and the first electronic device 100 and the second electronic device 200 establish a connection through a BT protocol. The user may enter the OSD by manipulating a physical key on the display to select either the first mode or the second mode in the OSD. When the first display screen 1001 is a touch screen, the user may also perform a touch operation on the first display screen 1001 to enter an OSD to perform selection of the first mode or the second mode.
After the user selects the first mode, the display driver chip may read the first EDID from the first memory 1004 in response to a negotiation request sent by the notebook computer, and the display driver chip may transmit the first EDID to the SOC chip, and the SOC chip may control the BT communication module to transmit the first EDID to the notebook computer to perform a communication negotiation with the notebook computer. After the communication negotiation between the notebook computer and the display is successful, the application scene of transmitting the video stream and the audio stream of the notebook computer to the display, such as a video projection screen playing scene, can be achieved. After the user selects the second mode, the display driver chip may read the second EDID from the third memory 1006 in response to the negotiation request sent by the notebook computer, and the display driver chip may transmit the second EDID to the SOC chip, and the SOC chip may control the BT communication module to transmit the second EDID to the notebook computer to perform communication negotiation with the notebook computer. After the communication negotiation between the notebook computer and the display is successful, the application scene that the notebook computer only transmits the video stream to the display and does not transmit the audio stream to the display can be achieved, the interference between the audio equipment of the notebook computer and the audio equipment of the display can be avoided, or the scene requirement that a user only expects to throw a picture to the display and the sound is not transmitted to the display can be met.
As shown in fig. 8a, taking the first electronic device 100 as a smart screen and the second electronic device 200 as a notebook, the first electronic device 100 and the second electronic device 200 are connected by Wi-Fi protocol. When the first electronic device 100 successfully communicates with the second electronic device 200 based on the first EDID, the sound setup interface of the second electronic device 200 may present the audio playback device of the first electronic device 100 (e.g., the speaker in the first audio module 1002) and the audio playback device of the second electronic device 200 (e.g., the speaker in the second audio module 2002).
As shown in fig. 8b, taking the first electronic device 100 as a smart screen and the second electronic device 200 as a notebook computer, the first electronic device 100 and the second electronic device 200 are connected by Wi-Fi protocol, and the second EDID records the display capability information of the first display screen 1001, but does not record the audio capability information of the first audio module 1002. When the first electronic device 100 successfully communicates with the second electronic device 200 based on the second EDID, the sound setting interface of the second electronic device 200 presents only the audio playback device of the second electronic device 200, i.e., the audio playback device of the first electronic device 100 is not visible on the second electronic device 200.
Referring to fig. 9, an embodiment of the present application provides a communication method applied to a first electronic device 100, where the first electronic device 100 includes a first display 1001 and a first audio module 1002. The first electronic device 100 stores the first EDID and the second EDID. The first EDID records the display capability information of the first display screen 1001 and the audio capability information of the first audio module 1002. The second EDID records the display capability information of the first display screen 1001 without recording the audio capability information of the first audio module 1002, or the second EDID records the audio capability information of the first audio module 1002 without recording the display capability information of the first display screen 1001. In this embodiment, the communication method may include:
step 91, the first electronic device 100 receives a negotiation request sent by the second electronic device 200, where the negotiation request is used for performing communication negotiation with the first electronic device 100.
In some embodiments, the first electronic device 100 and the second electronic device may establish a connection in a wired manner or a wireless manner, so as to implement application scenarios such as screen expansion, screen projection, multi-screen collaboration, and the like. Taking the screen-projection application scenario as an example, the second electronic device 200 is a source device, and the first electronic device 100 is a destination device. When the first electronic device 100 and the second electronic device 200 establish a connection in a wired manner or a wireless manner, the second electronic device 200 may confirm the audio and video capability of the first electronic device 100 by performing a communication negotiation with the first electronic device 100, so as to facilitate a subsequent transmission of an audio and video stream to the first electronic device 100, and realize that the content played by the second electronic device 200 is projected to the first electronic device 100 for playing. For example, after the second electronic device 200 is the source device and the first electronic device 100 is the destination device and the first electronic device 100 establishes a connection with the second electronic device 200 in a wired manner or a wireless manner, before the second electronic device 200 transmits the screen-throwing data to the first electronic device 100, the second electronic device 200 may send a negotiation request to the first electronic device 100, and the first electronic device 100 may obtain the first EDID or the second EDID in response to the negotiation request and transmit the first EDID or the second EDID to the second electronic device 200 in a wired manner or a wireless manner, so as to perform a communication negotiation with the second electronic device 200, and further the second electronic device 200 may confirm the audio/video capability provided by the first electronic device 100 based on the first EDID or the second EDID, so as to facilitate the subsequent transmission of the screen-throwing data (audio data stream and/or video data stream) to the first electronic device.
Step 92, when the first electronic device 100 is in the first mode, the first electronic device 100 obtains the first EDID and sends it to the second electronic device 200.
Step 93, when the first electronic device 100 is in the second mode, the first electronic device 100 obtains the second EDID and sends it to the second electronic device 200.
In some embodiments, when the first electronic device 100 is in the first mode and the first electronic device 100 and the second electronic device 200 establish a connection through a wired manner or a wireless manner, the second electronic device 200 may send a negotiation request to the first electronic device 100, and the first electronic device 100 may obtain the first EDID in response to the negotiation request, and transmit the first EDID to the second electronic device 200 through a wired manner or a wireless manner, so as to perform a communication negotiation with the second electronic device 200, and further the second electronic device 200 may obtain the audio and video capability of the first electronic device 100 based on the first EDID.
In some embodiments, when the first electronic device 100 successfully communicates with the second electronic device 200 based on the first EDID, the second electronic device 200 may confirm that the first electronic device 100 has the audio/video playing capability, and the second electronic device 200 may transmit the audio stream and the video stream to the first electronic device 100 in a wired manner or a wireless manner, so as to play the screen-cast content on the first electronic device 100.
In some embodiments, when the first electronic device 100 is in the second mode and the first electronic device 100 and the second electronic device 200 establish a connection in a wired manner or a wireless manner, the second electronic device 200 may send a negotiation request to the first electronic device 100, and the first electronic device 100 may obtain the second EDID in response to the negotiation request, and transmit the second EDID to the second electronic device 200 in a wired manner or a wireless manner, so as to perform a communication negotiation with the second electronic device 200, and further the second electronic device 200 may obtain the audio and video capability of the first electronic device 100 based on the second EDID.
Taking the example that the second EDID records the display capability information of the first display screen 1001, but does not record the audio capability information of the first audio module 1002. When the first electronic device 100 successfully negotiates with the second electronic device 200 based on the second EDID, the second electronic device 200 may confirm that the first electronic device 100 is video-capable and not audio-capable. The second electronic device 200 may transmit the video stream to the first electronic device 100 by wire or wirelessly, while the audio stream is not transmitted. The audio playback device of the first audio module 1002 is not visible on the second electronic device 200.
In some embodiments, the first electronic device 100 may switch between the first mode and the second mode. For example, when the first electronic device 100 receives the first operation instruction in the first mode, the first electronic device 100 is switched from the first mode to the second mode, and when the first electronic device 100 receives the second operation instruction in the second mode, the first electronic device 100 is switched from the second mode to the first mode. The first operation instruction and the second operation instruction may be instructions triggered by a user operating an entity key of the first electronic device 100, or by a touch operation on the first display screen 1001, or by an operation on a remote controller paired with the first electronic device 100.
In some embodiments, after the first electronic device 100 successfully negotiates with the second electronic device 200 based on the first EDID, and the first electronic device 100 receives the first operation instruction, the communication connection between the first electronic device 100 and the second electronic device 200 is disconnected (the communication connection with the second electronic device 200 may be disconnected by the first electronic device 100 or the communication connection with the first electronic device 100 may be disconnected by the second electronic device 200), the second electronic device 200 may resend the negotiation request to the first electronic device 100, and the first electronic device 100 may obtain the second EDID in response to the negotiation request and send the second EDID to the second electronic device 200 to carry out the communication negotiation again with the second electronic device 200. After the first electronic device 100 successfully communicates with the second electronic device 200 based on the second EDID, and the first electronic device 100 receives the second operation instruction, the communication connection between the first electronic device 100 and the second electronic device 200 is disconnected, the second electronic device 200 may resend the negotiation request to the first electronic device 100, and the first electronic device 100 may obtain the first EDID and send the first EDID to the second electronic device 200 in response to the negotiation request, so as to resend the communication negotiation with the second electronic device 200.
For example, taking a screen-projection scenario as an example, after the first electronic device 100 successfully negotiates with the second electronic device 200 based on the first EDID, and the first electronic device 100 receives the first operation instruction, the screen-projection connection between the first electronic device 100 and the second electronic device 200 will be disconnected; after the first electronic device 100 successfully communicates with the second electronic device 200 based on the second EDID, and the first electronic device 100 receives the second operation instruction, the screen-projection connection between the first electronic device 100 and the second electronic device 200 is disconnected.
According to the negotiation communication method, two groups of EDID are arranged in the first electronic device, one group of EDID records the audio and video capabilities of the first electronic device, the other group of EDID only records the audio capabilities or video capabilities of the first electronic device, and the use scenes of multiple devices are enriched.
Referring to fig. 10, the method is applied to the first electronic device 100 and the second electronic device 200. The first electronic device 100 comprises a first display 1001 and a first audio module 1002. The second electronic device 200 comprises a second display 2001 and a second audio module 2002. The first electronic device 100 stores the first EDID and the second EDID. The first EDID records the display capability information of the first display screen 1001 and the audio capability information of the first audio module 1002. The second EDID records the display capability information of the first display screen 1001 without recording the audio capability information of the first audio module 1002, or the second EDID records the audio capability information of the first audio module 1002 without recording the display capability information of the first display screen 1001. The following description will take the second electronic device 200 as a source device and the first electronic device 100 as a destination device as an example. In this embodiment, the negotiation communication method may include:

Taking the screen projection scenario as an example, the second electronic device 200 is a source device, and the first electronic device 100 is a destination device. After the first electronic device 100 and the second electronic device 200 are connected in a wired manner or a wireless manner, before the second electronic device 200 sends an audio/video stream to the first electronic device 100, the second electronic device 200 can confirm the audio/video capability of the first electronic device 100 through communication negotiation with the first electronic device 100, so that the subsequent sending of the audio/video stream to the first electronic device 100 is facilitated, and the screen projection of the content played by the second electronic device 200 to the first electronic device 100 is realized for playing.
In step 102, the first electronic device 100 responds to the negotiation request, obtains the first EDID or the second EDID, and sends the obtained first EDID or the obtained second EDID to the second electronic device 200 to perform communication negotiation with the second electronic device 200.
In some embodiments, when the first electronic device 100 receives a negotiation request generated by the second electronic device 200, the first electronic device 100 may obtain the first EDID or the second EDID in response to the negotiation request, and send the negotiation request to the second electronic device 200 to perform communication negotiation with the second electronic device 200, so that the second electronic device 200 may obtain the audio and video capability of the first electronic device 100 based on the first EDID or the second EDID.
In some embodiments, the first electronic device 100 may include a first mode and a second mode. When the first electronic device 100 is in the first mode, the first electronic device obtains the first EDID and sends the first EDID and the first EDID to the second electronic device 200 to perform communication negotiation with the second electronic device 200, and when the first electronic device 100 is in the second mode, the first electronic device obtains the second EDID and sends the second EDID to the second electronic device 200 to perform communication negotiation with the second electronic device 200.
In some embodiments, the first electronic device 100 may switch between the first mode and the second mode. For example, when the first electronic device 100 receives the first operation instruction in the first mode, the first electronic device 100 is switched from the first mode to the second mode, and when the first electronic device 100 receives the second operation instruction in the second mode, the first electronic device 100 is switched from the second mode to the first mode.
In some embodiments, after the first electronic device 100 successfully communicates with the second electronic device 200 based on the first EDID, and the first electronic device 100 receives the first operation instruction, the screen-drop connection between the first electronic device 100 and the second electronic device 200 is disconnected, the second electronic device 200 resends the negotiation request to the first electronic device 100, and the first electronic device 100 may obtain the second EDID and send the second EDID to the second electronic device 200 in response to the negotiation request, so as to resend the communication negotiation with the second electronic device 200. After the first electronic device 100 successfully communicates with the second electronic device 200 based on the second EDID, and the first electronic device 100 receives the second operation instruction, the screen-on connection between the first electronic device 100 and the second electronic device 200 is disconnected, the second electronic device 200 resends the negotiation request to the first electronic device 100, and the first electronic device 100 may respond to the negotiation request to obtain the first EDID and send the first EDID to the second electronic device 200 to renegotiate with the second electronic device 200.
In some embodiments, the first EDID and the second EDID may be stored in different memories or may be stored in the same memory. When the first EDID and the second EDID are stored in the same memory, the first EDID and the second EDID may have different memory addresses, so that the first EDID or the second EDID can be read from the memory based on the memory addresses later.
In some embodiments, taking the example that the second EDID records the display capability information of the first display screen 1001, the audio capability information of the first audio module 1002 is not recorded. When the first electronic device 100 successfully communicates with the second electronic device 200 based on the first EDID, the second electronic device 200 may confirm that the first electronic device 100 has the audio/video playing capability, and the second electronic device 200 may transmit the audio stream and the video stream to the first electronic device 100 in a wired manner or a wireless manner, so as to play the screen content on the first electronic device 100. When the first electronic device 100 successfully negotiates with the second electronic device 200 based on the second EDID, the second electronic device 200 may confirm that the first electronic device 100 is video-capable and not audio-capable. The second electronic device 200 may transmit the video stream to the first electronic device 100 by wire or wirelessly, while the audio stream is not transmitted. The audio playback device of the first audio module 1002 is not visible on the second electronic device 200.
According to the negotiation communication method, two groups of EDID are arranged in the first electronic device, one group of EDID records the audio and video capabilities of the first electronic device, the other group of EDID only records the audio capabilities or video capabilities of the first electronic device, the use scenes of multiple devices are enriched, when the first electronic device selects the EDID which only records the audio capabilities or video capabilities to carry out communication negotiation with the second electronic device, the video stream and the audio stream of the second electronic device can be separated and transmitted, the audio playing device or the video playing device of the first electronic device cannot be seen on the second electronic device, the audio and video interference between the two electronic devices can be avoided, the bandwidth can be saved, and the use experience of a user can be improved.
