[0046] Implementation Methods of the Application

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0048] Embodiments of the present application provide a playback control method, device, and computer-readable storage medium.

[0049] Please refer to Figure 1a, which is a system schematic diagram of the playback control system provided in an embodiment of the present application. The system may include at least one terminal device 1000. The terminal device 1000 may be a mobile phone, tablet computer, computer, television or other device. A calculator application may be installed in the terminal device 1000, and users can perform simple mathematical calculations through the calculator application.

[0050] The embodiment of the present application provides a playback control method, which can be executed by a terminal device 1000. As shown in Figure 1a, the terminal device 1000 obtains the data to be transmitted received by the Bluetooth module at a preset time interval to determine the data length of the data to be transmitted; determines the current playback state based on the data length of the data to be transmitted; receives a playback state acquisition request sent by the Bluetooth player, sends the current playback state to the Bluetooth player, and triggers the Bluetooth player to perform playback control based on the current playback state. In this way, the current playback state of the terminal device is determined by the data length of the data to be transmitted received by the Bluetooth module, so that the terminal device can determine the current playback state when playing audio in any playback scenario, thereby triggering the Bluetooth player to perform corresponding playback control according to the current playback state determined by the terminal device.

[0051] It should be noted that the scenario diagram of the playback control system shown in Figure 1a is only an example. The playback control system and scenario described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided by the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the playback control system and the emergence of new business scenarios, the technical solution provided by the embodiment of the present application is also applicable to similar technical problems.

[0052] In this embodiment, the description will be made from the perspective of a playback control device, which can be integrated into a computer device having a storage unit and a microprocessor installed therein and having computing capabilities.

[0053] Please refer to Figure 1b, which is a flow chart of a playback control method provided in an embodiment of the present application. The playback control method includes:

[0054] In step 101, the data to be transmitted received by the Bluetooth module is acquired at a preset time interval, and the data length of the data to be transmitted is determined.

[0055] The difference between this application and the prior art is that the terminal device in the prior art can only obtain the player's playback status in non-HDMI, VOD and other playback scenarios, and thus control the playback of the audio system based on the player's playback status. However, this application determines the current playback status of the terminal device by the length of the data to be transmitted to the audio system when the audio system and the terminal device are connected via Bluetooth for playback, and then triggers the audio system to control playback based on the determined current playback status.

[0056] Specifically, no matter whether the playback scenario is HDMI, VOD, or other playback scenarios, as long as it is played through a Bluetooth player, Audio Hal or the Audio bottom layer will send the data to be transmitted to the Bluetooth module to be transmitted to the Bluetooth player. If the terminal device is currently in a non-playing state, for example: not playing state, or paused playback state, the data length of the data to be transmitted is 0; if the terminal device is currently in a playing state, the data length of the data to be transmitted is not 0.

[0057] The preset time interval may be 5ms or 10ms, which is not limited here.

[0058] In step 102, the current playing state is determined based on the data length of the data to be transmitted.

[0059] Since different playback states may cause the data length of the data to be transmitted to be 0 or not 0, the current playback state may be determined based on the data length of the data to be transmitted.

[0060] In some implementations, the step of determining the current playback state based on the data length of the data to be transmitted includes:

[0061] (1) obtaining a target number of times that the data length of the data to be transmitted exceeds a preset data length within a preset statistical period;

[0062] (2) comparing the target number of times with the preset number of times to obtain a comparison result;

[0063] (3) Determine the current playback status based on the comparison result.

[0064] Among them, in order to avoid the problem of inaccurate determination of the current playback state due to the playback state being paused for a short period of time under user control, a preset statistical period can be set, for example, 1s. Within 1s, according to a preset time interval, for example, 10ms, the data length of 1s / 10ms = 100 data to be transmitted can be obtained. The preset data length here is 0, then the target number of times the data length of the data to be transmitted exceeds the preset data length within the preset statistical period is obtained, that is, the target number of times the data length of the data to be transmitted sent in the playback state is obtained. For example, the target number of times the data length exceeds 0 among the statistical number of 100 data to be transmitted is 80 times.

[0065] Specifically, a preset number of times is set, for example, 60 times, and the target number of times is compared with the preset number of times, thereby determining the current playback state based on the comparison result.

[0066] In some implementations, the step of determining the current playback state based on the comparison result includes:

[0067] (1.1) If the comparison result indicates that the target number of times reaches or exceeds the preset number of times, the current playback state is determined to be the playback state;

[0068] (1.2) If the comparison result indicates that the target number of times does not reach the preset number of times, it is determined that the current playback state is a non-playing state.

[0069] Among them, if the comparison result indicates that the target number of times reaches or exceeds the preset number of times, it means that within the preset statistical period, there is a large amount of data to be transmitted with actual data, and the current playback state is the playback state; if the comparison result indicates that the target number of times does not reach the preset number of times, it means that within the preset statistical period, there is a large amount of data to be transmitted with no actual data, and the current playback state is the non-playing state.

[0070] In step 103, a playback status acquisition request sent by the Bluetooth player is received, the current playback status is sent to the Bluetooth player, and the Bluetooth player is triggered to perform playback control based on the current playback status.

[0071] Among them, after determining the current playback status of the terminal device, since some Bluetooth speakers that support AVRCP Profile will actively obtain the current playback status from the terminal device, when the terminal device receives the playback status acquisition request sent by the Bluetooth player, it will send the current playback status to the Bluetooth player, so that the Bluetooth player can control the playback according to the current playback status determined by the terminal device.

[0072] For example, when the Bluetooth player obtains from the terminal device that the current playback state is the playing state, it plays according to the data to be transmitted received from the terminal device; when the Bluetooth player obtains from the terminal device that the current playback state is the non-playing state, the Bluetooth player also does not play synchronously.

[0073] In some implementations, the step of receiving a playback status acquisition request sent by the Bluetooth player and sending the current playback status to the Bluetooth player includes:

[0074] (1) receiving a playback status acquisition request sent by the Bluetooth player, and determining a historical statistical period before the preset statistical period;

[0075] (2) determining the historical playback status determined in the historical statistical period;

[0076] (3) If the current playback status is different from the historical playback status, the current playback status is sent to the Bluetooth player.

[0077] To reduce resource usage and reduce the operating speed of both devices due to frequent interactions between the terminal device and the Bluetooth player, the terminal device, when receiving a playback status acquisition request from the Bluetooth player, may prioritize determining a historical playback status determined in a historical statistical period prior to the preset statistical period. The current playback status is transmitted to the Bluetooth player only if the current playback status differs from the historical playback status.

[0078] For example, if the preset statistical period is from the 1st to the 2nd second at 10:10, then a historical statistical period within the preset statistical period is from the 0th to the 1st second at 10:10. If the current playback state determined by the preset statistical period is the non-playing state, and the historical playback state determined by the historical statistical period is the playing state, then the current playback state being the non-playing state is sent to the Bluetooth player, so that the Bluetooth player changes from controlling playback triggered by the historical playback state determined by the historical statistical period being the playing state to controlling non-playing (pausing or stopping playback) triggered by the current playback state determined by the preset statistical period being the non-playing state.

[0079] In some embodiments, the method further comprises:

[0080] If the current play state is the same as the historical play state, the current play state is prohibited from being sent to the Bluetooth player, triggering the Bluetooth player to continue to perform play control according to the historical play state.

[0081] As shown in FIG1c , FIG1c is a first signaling interaction diagram between a terminal device and a Bluetooth player provided in an embodiment of the present application.

[0082] Among them, if the current playback status is the same as the historical playback status, it means that the current playback status follows the previous historical playback status. At this time, the playback control of the Bluetooth player is based on the historical playback status, so the terminal device may not send the current playback status to the Bluetooth player, thereby triggering the Bluetooth player to follow the playback control of the historical playback status.

[0083] For example, if the historical playback status is playing and the current playback status is also playing, the terminal device does not send the playback status to the Bluetooth player. When the Bluetooth player does not receive the playback status of the terminal device within a period of time, it continues to use the historical playback status for playback control.

[0084] In some implementations, after the step of determining the current playback state based on the data length of the data to be transmitted, the method further includes:

[0085] (1) receiving a pause play request sent by the Bluetooth player, and determining whether the current play state is a play state;

[0086] (2) If the current playback state is the playback state, obtain the device number of the Bluetooth player;

[0087] (3) Construct a rejection condition based on the pause playback request and the device number.

[0088] Among them, in the prior art, when the Bluetooth player sends a pause play request (AVDTP_SUSPENGD) to the terminal device due to an abnormality of the Bluetooth player itself, if the current play state is play, the terminal device will suspend the audio node, which will cause the speaker device to be silent. In order to further solve this technical problem, the present application can obtain the device number of the Bluetooth player when the current play state is play and a pause play request sent by the Bluetooth player is received. The device number can be the name of the Bluetooth player's audio system, or the device address, etc., which can uniquely identify the number of the Bluetooth player. According to the device number and the pause play request, a rejection condition is constructed.

[0089] Specifically, please refer to Table 1. Table 1 constructs a rejection condition, which is used to reject the rejection event "pause play request" sent by the rejection device "Bluetooth player 1".

[0090] In some implementations, after the step of constructing a rejection condition based on the pause playback request and the device number, the method further includes:

[0091] (1) receiving a pause play request and obtaining a sending device number of a device that sends the pause play request;

[0092] (2) If the sending device number is the same as the device number in the rejection condition, the pause playback request is rejected.

[0093] As shown in Figure 1d, which is a second signaling interaction diagram between a terminal device and a Bluetooth player provided in an embodiment of the present application, after establishing a rejection condition, if a pause play request is received thereafter, the sending device number of the device sending the pause play request is obtained. If the sending device number is the same as the device number in the rejection condition, the pause play request is rejected.

[0094] For example, if the sending device number of the device sending the pause play request is "Bluetooth player 1", and its device number is the same as the rejecting device "Bluetooth player 1" in the rejection condition, the pause play request will be rejected, and the silent self-healing of the audio will be achieved.

[0095] Specifically, in order to avoid the pause playback request being initiated by the user controlling the Bluetooth player, a premise for constructing a rejection condition can be set. For example, if the terminal device receives multiple pause playback requests initiated by the Bluetooth player within a specified time period, and each time the pause playback request is received, the current playback status is playing, then a rejection condition is constructed.

[0096] As can be seen from the above, the embodiment of the present application obtains the data to be transmitted received by the Bluetooth module at a preset time interval to determine the data length of the data to be transmitted; determines the current playback status based on the data length of the data to be transmitted; receives a playback status acquisition request sent by the Bluetooth player, sends the current playback status to the Bluetooth player, and triggers the Bluetooth player to perform playback control based on the current playback status. In this way, the current playback status of the terminal device is determined by the data length of the data to be transmitted received by the Bluetooth module. This allows the terminal device to determine the current playback status when playing audio in any playback scenario, thereby triggering the Bluetooth player to perform corresponding playback control based on the current playback status determined by the terminal device.

[0097] To facilitate better implementation of the playback control method provided in the embodiment of the present application, the embodiment of the present application also provides a device based on the above playback control method. The meanings of the terms are the same as those in the above playback control method, and the specific implementation details can be referred to the description in the method embodiment.
