[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] The present invention provides a sound mode control method. The sound mode control method is applied to a sound source device. The sound source device can be an audio system device (such as an audio, a soundbar, an amplifier device, etc.) or a CEC device (Consumer Electronics Control). The sound source device is configured with a sound mode transmission protocol (for transmitting data information of the sound mode parameters of the sound source device), and the sound source device can establish a data communication relationship with a display device (a device that can display the sound mode parameters of the sound source device, such as a TV) through an HDMI data cable (High-Definition Multimedia Interface, a digital interface for transmitting high-definition video and audio).

[0054] Among them, as Figure 1 shown, the standard frame of the sound mode transmission protocol (also known as the SMT protocol, i.e., the SoundMode Transmission protocol) configured in the sound source device includes 16 fields.

[0055] As Figure 2As shown in the figure, the first field of the standard frame of the sound mode transmission protocol is the header block of the sound mode transmission protocol, which represents the logical address of the sound source device and the logical address of the display device connected to the sound source device through the HDMI data cable, so as to indicate from which device the data information transmitted through the sound mode transmission protocol is sent to which device. Each type of sound source device corresponds to a logical address (currently there are 16 logical addresses, from 0x0 to 0xF. For example, 0x0 is for TV and 0xF is for radio); the second field of the standard frame of the sound mode transmission protocol represents the operation code of the communication standard protocol of the sound source device; the third field to the fifth field of the standard frame of the sound mode transmission protocol represent the manufacturer identifier of the sound source device. The sound source device with this manufacturer identifier is indicated to support the sound mode transmission protocol; as Figure 3 As shown in the figure, the sixth field of the standard frame of the sound mode transmission protocol represents the private operation code of the sound mode transmission protocol; the seventh field to the sixteenth field of the standard frame of the sound mode transmission protocol represent the parameter information corresponding to the private instruction of the sound mode transmission protocol.

[0056] Furthermore, as Figure 4 As shown in the figure, it is a schematic diagram of the description of the parameter information corresponding to the private instruction of the standard frame of the sound mode transmission protocol. If the parameter information is Devices SN (device serial number), it represents the serial number of the sound source device; if the parameter information is SMT Version (sound mode transmission protocol version number), it represents the version number of the sound mode transmission protocol; if the parameter information is EQ Mode (audio mode parameter information), it represents the sound mode parameter corresponding to the user interface of the display device; if the parameter information is Status (status information), it represents the status information indicating whether the sound mode of the sound source device is successfully adjusted and set.

[0057] As Figure 5 As shown in the figure, the sound mode control method proposed by the present invention includes steps S100 - step S500:

[0058] Step S100, determine the handshake status information according to the handshake request information sent by the display device connected to the sound source device through the HDMI data cable and the data transmission status of the sound mode transmission protocol;

[0059] Among them, the handshake status information is used to represent whether the sound source device can perform data transmission with the display device through the sound mode transmission protocol;

[0060] Furthermore, in step S100, determining the handshake status information according to the handshake request information sent by the display device connected to the sound source device through the HDMI data cable and the data transmission status of the sound mode transmission protocol includes steps S110 - step S130:

[0061] Step S110: In response to receiving the handshake request information sent by a display device connected to a sound source device via an HDMI data cable, obtain the data transmission status of the sound mode transmission protocol at the current moment;

[0062] The handshake request corresponding to the handshake request information is a request sent by the display device to establish a data transmission relationship with the sound source device.

[0063] The data transmission status is the status of whether the sound mode parameter data can be normally transmitted through the sound mode transmission protocol.

[0064] Step S120: When the data transmission status of the sound mode transmission protocol at the current moment is normal, determine the first status information as the handshake status information;

[0065] Step S130: When the data transmission status of the sound mode transmission protocol at the current moment is abnormal, determine the second status information as the handshake status information.

[0066] The first status information indicates that the sound mode parameter data can be normally transmitted through the sound mode transmission protocol, and the second status information indicates that the sound mode parameter data cannot be normally transmitted through the sound mode transmission protocol.

[0067] Step S200: Send the handshake status information to the display device;

[0068] Step S300: In response to receiving the sound mode request instruction sent by the display device, send the sound mode data information configured by the sound source device to the display device through the sound mode transmission protocol;

[0069] The sound mode data information configured by the sound source device is the parameter information of the sound modes supported by the sound source device (such as voice enhancement, bass control, treble control, etc.).

[0070] Step S400: In response to receiving the sound mode setting instruction sent by the display device, set the current sound mode of the sound source device to the sound mode corresponding to the sound mode setting instruction;

[0071] Step S500: Determine the sound mode setting status information according to the sound mode setting status of the sound source device, and send it to the display device;

[0072] Among them, the sound mode setting status information is used to indicate whether the current sound mode of the sound source device is set to the sound mode corresponding to the sound mode setting instruction.

[0073] Further, in step S500, determining the sound mode setting status information according to the sound mode setting status of the sound source device includes steps S510 - S520:

[0074] Step S510: When the current sound mode of the sound source device is set to the sound mode corresponding to the sound mode setting instruction, determine the third status information as the sound mode setting status information.

[0075] The third status information indicates that after receiving the sound mode setting instruction sent by the display device, the sound source device successfully sets the sound mode to the sound mode corresponding to the sound mode setting instruction.

[0076] Step S520: When the current sound mode of the sound source device is not set to the sound mode corresponding to the sound mode setting instruction, determine the fourth status information as the sound mode setting status information.

[0077] The fourth status information indicates that after receiving the sound mode setting instruction sent by the display device, the sound source device fails to set the sound mode to the sound mode corresponding to the sound mode setting instruction.

[0078] In addition, a display device connected to the sound source device through an HDMI data cable, when forming a connection relationship with the sound source device, is used to execute steps S001 - S002:

[0079] Step S001: When connected to the sound source device through an HDMI data cable, obtain the device information of the sound source device.

[0080] Each sound source device corresponds to a device information, and the device information is used to represent the device type of the corresponding sound source device.

[0081] Step S002: When the device information of the sound source device indicates that the device type of the sound source device is a preset device type, send a handshake request information to the sound source device.

[0082] If the device type corresponding to the device information of the sound source device is a preset device type (such as the audio system device type), it means that the sound source device connected to the display device is a device that can adjust the sound mode.

[0083] Furthermore, when the display device receives the handshake status information sent by the sound source device, it is used to execute step S003:

[0084] Step S003: In response to receiving the handshake status information sent by the sound source device, when the handshake status information is the first status information, send a sound mode request instruction to the sound source device.

[0085] When the handshake status information is the first status information, it indicates that the audio mode parameter data can be normally transmitted between the display device and the sound source device through the audio mode transmission protocol. At this time, the display device sends an audio mode request instruction to the sound source device to obtain the parameter data information of the audio modes supported by the sound source device.

[0086] When the handshake status information is the second status information, it indicates that the audio mode parameter data cannot be normally transmitted between the display device and the sound source device through the audio mode transmission protocol. At this time, this connection is terminated.

[0087] Furthermore, when the display device receives the audio mode data information sent by the sound source device through the audio mode transmission protocol, it is used to execute steps S004 - S005:

[0088] Step S004: In response to receiving the audio mode data information sent by the sound source device through the audio mode transmission protocol, obtain the audio mode setting instruction input by the user;

[0089] The audio mode setting instruction is an instruction for controlling the adjustment of the audio mode of the sound source device, and the user can send the audio mode setting instruction through the controller of the display device (such as a remote control).

[0090] Step S005: Send the audio mode setting instruction to the sound source device through the audio mode transmission protocol.

[0091] Furthermore, when the display device receives the audio mode setting status information, if the audio mode setting status information is the third status information, then display the parameters of the audio mode after successful setting. If the audio mode setting status information is the fourth status information, then do not display or display the setting failure information.

[0092] Specifically, as Figure 6 、 Figure 7 and Figure 8 shown, when a sound source device that supports the audio mode transmission protocol (i.e., the soundbar in Figure 6 , the Audio system in Figure 7 , the Amplifier in Figure 8 ) and a display device (i.e., the TV in Figure 6 and Figure 7 , and the TV CEC in Figure 8 ) are connected by an HDMI data cable, the hot plug (i.e., the Hotplug in Figure 7 ) pin of the display device will detect a 5V voltage. Then the display device will determine that there is an HDMI device connected at this time, and the display device obtains the device information of the connected sound source device through the HDMI CEC basic protocol (i.e., Figure 7in the device info), if the device type of the device info of the sound source device is a preset device type (such as Figure 7 in the audio system), the display device sends a handshake request message to the sound source device (that is, Figure 7 HandShakeRequest in it) to determine whether the sound source device supports the sound mode transmission protocol. The sound source device determines the handshake status information according to the handshake request message and the data transmission status of the sound mode transmission protocol and sends it to the display device. When the display device receives that the handshake status information is the first status information (that is, Figure 7 HandshakeResponse in it), it sends a sound mode request instruction to the sound source device (that is, Figure 7 SMTDescriptor Request in it) to request to receive the parameter information of the sound mode supported by the sound source device. If the handshake status information received by the display device is the second status information (that is, Figure 6 Feature Abord in it), no processing is performed. When the sound source device receives the sound mode request instruction, it sends the data information of the sound mode supported by the sound source device (that is, Figure 7 SMTDescriptor Report in it) to the display device through the sound mode transmission protocol. After the display device receives the data information of the sound mode supported by the sound source device, the setting interface of the display device (that is, Figure 8 settingUI in it) waits for the sound mode setting instruction input by the user (that is, Figure 8 User in it) (that is, Figure 8 set soundmode on TV side in it). After the setting interface receives the sound mode setting instruction input by the user (to control the sound source device to adjust the sound mode, and the sound modes are such as movie, game, music, etc.), it sends a Set EQ Mode instruction to the display device. After the display device receives it, it sends this instruction to the sound source device through the sound mode transmission protocol. After the sound source device receives the Set EQ Mode instruction, it adjusts the current sound mode according to the corresponding sound mode parameters in the sound mode setting instruction. After the sound source device finishes adjusting the sound mode, it sends the sound mode setting status information (that is, Figure 8 Report EQ Mode Status in it) to the display device according to the adjustment result, and when the sound mode setting status information is the third status information, it sends the parameters of the sound mode after successful setting to the display device for display. In addition, when the user directly sends a sound mode setting instruction to the sound source device (that is, Figure 8When setting the sound mode on the amplifier side), after the sound source device completes setting the sound mode, it will also send a sound mode setting status message to the display device (i.e., Figure 8 the SMT Report CurrentEQ Mode in

[0093] In addition, the present application also proposes a sound source device 100. The sound source device 100 is configured with the above-mentioned sound mode transmission protocol. The sound source device can establish a data communication relationship with the display device through an HDMI data cable, such as Figure 9 shown. The sound source device 100 includes:

[0099] Among them, the standard frame of the sound mode transmission protocol includes 16 fields; the first field of the standard frame of the sound mode transmission protocol represents the logical address of the sound source device and the logical address of the display device connected to the sound source device through the HDMI data cable; the second field of the standard frame of the sound mode transmission protocol represents the operation code of the communication standard protocol of the sound source device; the third to fifth fields of the standard frame of the sound mode transmission protocol represent the vendor identification of the sound source device; the sixth field of the standard frame of the sound mode transmission protocol represents the private operation code of the sound mode transmission protocol; the seventh to sixteenth fields of the standard frame of the sound mode transmission protocol represent the parameter information corresponding to the private instruction of the sound mode transmission protocol.

[0100] Among them, the method for the handshake status information determination module 110 to determine the handshake status information according to the handshake request information sent by the display device connected to the sound source device through the HDMI data cable and the data transmission status of the sound mode transmission protocol includes: in response to receiving the handshake request information sent by the display device connected to the sound source device through the HDMI data cable, obtaining the data transmission status of the sound mode transmission protocol at the current moment; in the case where the data transmission status of the sound mode transmission protocol at the current moment is the normal state, determining the first status information as the handshake status information; in the case where the data transmission status of the sound mode transmission protocol at the current moment is the abnormal state, determining the second status information as the handshake status information.

[0101] Among them, the method for the setting status information determination module 150 to determine the sound mode setting status information according to the sound mode setting status of the sound source device includes: in the case where the current sound mode of the sound source device is set to the sound mode corresponding to the sound mode setting instruction, determining the third status information as the sound mode setting status information; in the case where the current sound mode of the sound source device is not set to the sound mode corresponding to the sound mode setting instruction, determining the fourth status information as the sound mode setting status information.

[0102] Among them, the display device is used to perform the following steps: when connected to the sound source device through the HDMI data cable, obtaining the device information of the sound source device; in the case where the device information of the sound source device indicates that the device type of the sound source device is the preset device type, sending a handshake request information to the sound source device.

[0103] Furthermore, the display device is also used to perform the following steps: in response to receiving the handshake status information sent by the sound source device, in the case where the handshake status information is the first status information, sending a sound mode request instruction to the sound source device.

[0104] Further, the display device is further configured to perform the following steps: in response to receiving the sound mode data information sent by the sound source device through the sound mode transmission protocol, obtain the sound mode setting instruction input by the user; and send the sound mode setting instruction to the sound source device through the sound mode transmission protocol.

[0105] On the other hand, as a further feasible embodiment, the sound mode control method of the present application can be applied to the intelligent cockpit system of a vehicle. Specifically, the sound source device applied in the sound mode control method can be a speaker or an amplifier in the intelligent cockpit system, and the display device applied in the sound mode control method can be a display screen in the intelligent cockpit system (the central control screen of the vehicle or other entertainment display screens). Through the sound mode control method of the present application, the sound source device and the display device in the intelligent cockpit system are connected through an HDMI data cable, and a sound mode transmission protocol is established. When the user needs to adjust attributes such as the sound mode of the sound source device in the intelligent cockpit system, the sound mode of the sound source device can be directly adjusted through the controller of the display device (or the software program of the mobile phone terminal), without the need to adjust through the controller of the sound source device, which facilitates the user to set the parameters of the sound source device when entertaining in the vehicle.

[0106] For the sound mode control method of the present invention, first, according to the handshake request information sent by the display device connected to the sound source device through the HDMI data cable and the data transmission status of the sound mode transmission protocol, determine the handshake status information indicating whether the sound source device can perform data transmission with the display device through the sound mode transmission protocol, and send the handshake status information to the display device.

By configuring the sound mode transmission protocol in the sound source device, the user can adjust attributes such as the sound mode of the sound source device through the controller of the display device, without the need to prepare the controller of the sound source device, reducing the number of controllers used by the user. While saving equipment costs, it also facilitates the user's operation. The user does not need to purchase a corresponding model controller again for the sound source device whose controller is lost. Moreover, the sound mode transmission protocol of the present application is extended from the CEC basic protocol for device parameters. Therefore, the sound mode transmission protocol can be applied not only to the sound source device, but also to other CEC devices, expanding its application scenario range.
