[0029] Example 1

[0030] Figure 1 A flowchart of a media playback method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of multi-screen playback of media data. The method can be executed by a media playback device, which can be implemented in the form of hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0031] S110: Detect whether there is a conference module in the current device.

[0032] The current device may be the device where the video wall control module resides. The video wall control module may be the module that processes and transmits media data. The video wall control module receives media data from the conference module, processes the media data, synthesizes multiple images, and transmits them to the video wall. The conference module receives media data from at least one terminal device and transmits the media data to the video wall control module. The terminal device is responsible for collecting media data. The conference module can reside on the current device or on a separate device. Optionally, if the conference has a small number of participants, both the conference module and the video wall control module can reside on the current device. In this case, the current device receives, transmits, decodes, and encodes media data. The performance of the current device can meet the requirements for all media data processing processes, ensuring stable media data playback. Furthermore, having the conference module and the video wall control module as a single module can increase media data transmission speed. This improves media data transmission efficiency while ensuring stable media data playback. If the conference has a large number of participants, the conference module and the video wall control module can reside on separate devices, with the video wall control module belonging to the current device and the conference module to another device. At this time, the device where the conference module is located is only used to receive media data, and the current device is used to decode, encode and send media data, which alleviates the data processing pressure of the device where the conference module is located, ensures the normal processing and playback of media data, and ensures the stability of media data playback.

[0033] Specifically, it is possible to detect whether a conference module exists in the current device where the TV wall control module is located. Optionally, the current device can send a broadcast message to the conference module. After receiving the broadcast message, the conference module sends feedback information to the current device. After receiving the feedback information, the current device detects the feedback information to determine whether the conference module exists in the current device. The broadcast message may be a message confirming the device where the conference module is located. Exemplarily, the broadcast message may be a message such as "Is the conference module in the current device" or "Please confirm the device where the conference module is located." The feedback information may be a response message to the broadcast message. Exemplarily, if the broadcast message is "Is the conference module in the current device", the feedback information may be "yes" or "no". If the broadcast message is "Please confirm the device where the conference module is located", the feedback information may be the device information of the device where the conference module is located.

[0034] Optionally, the multi-screen configuration information can also be used to determine whether the device information to which the conference module in the front-end configuration information belongs is the same as the device information to which the TV wall control module in the current device belongs. If the device information is the same, it can be determined that the conference module exists in the current device. Among them, the multi-screen configuration information can be the configuration information required for multi-screen playback of media data. The multi-screen configuration information can include: the mapping relationship between the conference module and the TV wall control module, the mapping relationship between the port for sending media data of the conference module and the port for receiving media data of the TV wall control module, the mapping relationship between the port for sending media data of the TV wall control module and the multi-screen display window of the TV wall, and the media adaptation parameters of the TV wall, etc. The technician can set and adjust the multi-screen configuration information in the front-end page. The device information can be the unique identification information of the device. Exemplarily, the device information can be the IP address (Internet Protocol Address) of the device. The current device or other devices can be uniquely identified based on the device information.

[0035] S120: Monitor the port corresponding to the detection result and receive media data.

[0036] The detection result may include whether the conference module exists in the current device or not. Different detection results correspond to different ports. The port corresponding to the detection result is used to receive data sent by the conference module.

[0037] Media data can be data displayed on a TV wall. Optionally, media data can include video data, audio data, etc. Media data is collected by a terminal device and sent by the terminal device to the sending port of the conference module. The conference module sends the media data to the current device based on the mapping relationship between the port for sending media data of the conference module and the port for receiving media data of the TV wall control module in the multi-screen configuration information. Optionally, the conference module can receive media data sent by multiple terminal devices through multiple ports. Based on the mapping relationship between the port for sending media data of the conference module and the port for receiving media data of the TV wall control module, the current device can receive media data from multiple ports sent by the conference module.

[0038] Specifically, if the detection result indicates that the conference module exists in the current device, the port corresponding to the detection result indicating that the conference module exists in the current device is monitored, and media data sent by the conference module is received. If the detection result indicates that the conference module does not exist in the current device, the port corresponding to the detection result indicating that the conference module does not exist in the current device is monitored, and media data sent by the conference module is received.

[0039] S130: Send the media data to the TV wall, and control the TV wall to play the media data.

[0040] The TV wall can be used to display media data on multiple screens. Specifically, after the current device receives the media data, the TV wall control module in the current device decodes the media data and then encodes the media data corresponding to the port. The current device sends the encoded media data to the TV wall and controls the TV wall to play the media data. Optionally, the conference module can send the media data collected by multiple terminals to the receiving port corresponding to the current device through different sending ports of the conference module. The current device receives the media data and decodes and encodes the media data received by different ports respectively. Then, according to the one-to-one mapping relationship between the port for sending media data of the TV wall control module and the multi-screen display window of the TV wall in the multi-screen configuration information, the media data of the port can be displayed in the multi-screen display window corresponding to the TV wall.

[0041] The technical solution of the embodiment of the present invention detects whether a conference module exists in the current device; monitors the port corresponding to the detection result and receives media data; sends the media data to a TV wall and controls the playback of the media data on the TV wall; and realizes flexible selection of the port for receiving media data according to the device where the conference module is located, thereby ensuring the flexibility of media data processing, ensuring the stability of media data playback, and flexibly improving the transmission efficiency of media data.

[0042] Example 2

[0043] Figure 2 This is a flowchart of a media playback method provided by the second embodiment of the present invention. Based on the above embodiment, this embodiment monitors the port corresponding to the detection result, specifically as follows: if the detection result includes the existence of a conference module, monitor the local address port; or if the detection result includes the absence of a conference module, monitor the external network address port. Figure 2 As shown, the method includes:

[0044] S210: Detect whether there is a conference module in the current device. If so, execute S220; if not, execute S230.

[0045] S220: If the detection result includes the existence of a conference module, the local address port is monitored and media data is received.

[0046] The local address port can be the port that receives media data sent by the conference module of the current device. If the detection result indicates the presence of the conference module, the local address port is used to receive media data. Media data only needs to pass through a small number of switches in the current device, which improves media data transmission speed. It also avoids media data loss during multiple transmissions, ensures media data integrity, and further guarantees media data playback stability.

[0047] S230: When the detection result includes that the conference module does not exist, monitor the external network address port and receive media data.

[0048] The external network address port can be a port for receiving media data sent by the conference module of other devices. Other devices can be devices other than the current device. When using the external network address port for media data transmission, the media data needs to pass through the switch of the current device and multiple switches during the transmission to other devices. When using the external network address port for media data transmission, the transmission speed and media data integrity will be lower than when using the local address port for media data transmission. However, in this case, there are more participants in the meeting, and the amount of media data to be processed is larger, which consumes more system performance. Using the current device to decode, encode and send media data can effectively ensure the normal processing process of media data, avoid system crashes caused by media data processing by the same participant, and although some transmission speed and media data integrity are sacrificed, the stability of media data playback is guaranteed.

[0049] S240: Send the media data to the TV wall, and control the TV wall to play the media data.

[0050] The technical solution of the embodiment of the present invention flexibly realizes the selection of the local address port and the external network address port by monitoring the local address port when the detection result includes the existence of the conference module; or monitoring the external network address port when the detection result includes the absence of the conference module. In small meetings with fewer participants, while ensuring normal processing performance, the transmission efficiency and the integrity of the media data are further improved, and the stability of the media data playback is further guaranteed. In large meetings with more participants, it is guaranteed that a large amount of media data can be processed normally, and the stability of the media data is guaranteed. While taking into account meetings of different sizes, the stability of media data playback is guaranteed.

[0051] Example 3

[0052] Figure 3 This is a flowchart of a media playback method provided in Example 3 of the present invention. Based on the above embodiments, this embodiment sends media data to a TV wall, specifically comprising: obtaining media playback adaptation parameters of the TV wall; adjusting the media data using the media playback adaptation parameters; and sending the adjusted media data to the TV wall.

[0053] S310: Detect whether there is a conference module in the current device.

[0054] S320: Monitor the port corresponding to the detection result and receive media data.

[0055] S330: Obtain media playback adaptation parameters of the TV wall.

[0056] Media playback adaptation parameters may be adaptation parameters for media data played on a TV wall. The media playback adaptation parameters for a TV wall may be pre-set in the multi-screen configuration information. Different types of media data may require different types of media playback adaptation parameters. For example, if the media data is audio data, the types of media playback adaptation parameters may include frequency, number of sampling bits, number of channels, loudness, and bit rate. If the media data is video data, the types of media playback adaptation parameters may include resolution, bit rate, frame rate, video capacity, and video format.

[0057] Specifically, the media playback adaptation parameters for the TV wall adaptation may be obtained from the multi-screen configuration information.

[0058] S340: Adjust the media data using the media playback adaptation parameter.

[0059] Specifically, the TV wall control module in the current device decodes the media data to obtain decoded media data. The media playback parameters of the decoded media data are adjusted using the media playback adaptation parameters of the TV wall to obtain adjusted media data. The media playback parameters may be playback parameters of the decoded media data. The parameter type of the media playback parameters may be the same as the parameter type of the media playback adaptation parameters.

[0060] S350: Send the adjusted media data to the TV wall.

[0061] Specifically, the adjusted media data may be encoded, and based on a mapping relationship between a port for sending media data of the TV wall control module and a multi-screen display window of the TV wall, the encoded media data may be sent to the TV wall.

[0062] In an optional embodiment of the present invention, media playback adaptation parameters are used to adjust media data, which is specifically as follows: obtaining the media type of the media data; decoding the media data using a decoder corresponding to the media type; and encoding the decoded media data using an encoder corresponding to the media playback adaptation parameters to obtain adjusted media data.

[0063] Among them, S3401, obtain the media type of the media data.

[0064] The media type of the media data may include video data, audio data, and the like.

[0065] Specifically, the media data may be detected to obtain the media type of the media data.

[0066] S3402: Decode the media data using a decoder corresponding to the media type.

[0067] Specifically, according to the type of media data, a decoder corresponding to the media type may be created and selected, and the media data may be decoded using the decoder.

[0068] Exemplarily, if the media type is video data, the current device directly creates a video decoder and uses the video decoder to decode the video data; if the media type is audio data, the current device directly creates an audio decoder and uses the audio decoder to decode the audio data.

[0069] S3403 : Encode the decoded media data using an encoder corresponding to the media playback adaptation parameter to obtain adjusted media data.

[0070] Specifically, the current device may create an encoder corresponding to the media playback adaptation parameter according to the media playback adaptation parameter, and use the encoder to encode the decoded media data to obtain an encoder adjusted according to the media playback adaptation parameter.

[0071] This solution obtains the media type of media data; decodes the media data using a decoder corresponding to the media type; and encodes the decoded media data using an encoder corresponding to the media playback adaptation parameters to obtain adjusted media data. This achieves the adaptive creation of an encoder based on the media type, ensures the dynamic processing of media data, and thus ensures the stability of media data playback.

[0072] In an optional embodiment of the present invention, the media data includes a data packet, and obtaining the media type of the media data is specifically performed as follows: obtaining header identification information of the data packet; and determining the media type of the media data based on the header identification information.

[0073] Among them, S34011, obtain the header identification information of the data packet.

[0074] The header identification information may be the header identification information of the data packet. The header identification information is used to determine the type of the data packet. The header identification information may be set and adjusted based on the experience of the technician. The header identification information may include a numerical value or a string. For example, the header identification information may be a PT (Payload Type) value.

[0075] Specifically, if the media data includes a data packet, the packet header identification information of the data packet may be obtained.

[0076] S34012. Determine the media type of the media data based on the packet header identification information.

[0077] Specifically, the media type of the media data corresponding to the packet header identification information may be determined based on the packet header identification information.

[0078] For example, when the header identification information is preset to be 0-99, the media type of the media data is audio data, and when the header identification information is 100-199, the media type of the media data is video data. If the header identification information of the acquired data packet is 50, the media type of the media data can be determined as audio data based on the header identification information.

[0079] This solution introduces packet header identification information and uses it to determine the media type of media data. There is no need to detect and provide feedback on the media type of the media data in advance. The current device can directly determine the media type based on the packet header identification information and adaptively create a decoder, ensuring dynamic processing of media data and thus ensuring the stability of media data playback.

[0080] In an optional embodiment of the present invention, after sending the media data to the TV wall and controlling the playback of the media data in the TV wall, it also includes: receiving playback failure information; modifying media playback adaptation parameters according to the playback failure information; adjusting the media data using the updated media playback adaptation parameters; and sending the adjusted media data to the TV wall.

[0081] Among them, step A, receiving playback failure information.

[0082] The playback failure information may be a television playback failure information. The playback failure information may be fed back to the current device by the TV wall. The playback failure information may include the specific media adaptation parameters that caused the failure.

[0083] Specifically, the current device receives playback failure information fed back by the TV wall.

[0084] Step B: Modify media playback adaptation parameters according to playback failure information.

[0085] Specifically, the media playback adaptation parameters may be adjusted according to the playback failure information, thereby reducing the original single or multiple media playback adaptation parameters.

[0086] Step C: Use the updated media playback adaptation parameters to adjust the media data.

[0087] Specifically, the current device may use the updated media playback adaptation parameters to re-adjust the media playback parameters of the decoded media data.

[0088] Step D: Send the adjusted media data to the TV wall.

[0089] Specifically, the adjusted media data may be encoded and sent to a TV wall for display on the TV wall.

[0090] This solution receives playback failure information; modifies media playback adaptation parameters based on the playback failure information; adjusts media data using the updated media playback adaptation parameters; and sends the adjusted media data to the TV wall. In the event of playback failure of media data, the TV wall can automatically adjust the media playback adaptation parameters to adjust the media data, avoiding the situation where normal playback cannot be caused by mismatch of media playback adaptation parameters, realizing self-healing during the media data playback process, ensuring the fault tolerance of media data playback, and improving the stability of media data playback.

[0091] In an optional embodiment of the present invention, the playback fault information includes at least one of the following: resolution and frame rate.

[0092] Resolution can be the number of effective pixels per unit length. Examples include 360P, 480P, 720P, 1080P, and 4K. Frame rate can be a measure of the number of frames displayed. Examples include 30fps and 60fps.

[0093] For example, the playback failure information is set to a resolution of 1080P and a frame rate of 60fps, which prevents normal playback. The current device receives playback failure information fed back by the TV wall. According to the playback failure information, the media playback adaptation parameters can be adjusted to reduce the original single or multiple media playback adaptation parameters, such as adjusting the resolution to 720P and the frame rate to 30fps. The current device can use the updated media playback adaptation parameters to re-adjust the media playback parameters of the decoded media data. The adjusted media data can be encoded and sent to the TV wall for display on the TV wall.

[0094] This solution concretizes playback failure information into resolution and frame rate, and provides a specific example of playback failure caused by resolution and frame rate mismatch. By adaptively adjusting the resolution and frame rate, the self-healing ability of media data during playback is improved, and the stability of media data playback is improved.

[0095] The technical solution of the embodiment of the present invention obtains the media playback adaptation parameters of the TV wall; adjusts the media data using the media playback adaptation parameters; and sends the adjusted media data to the TV wall. Based on the media playback adaptation parameters of the TV wall, the media data is pre-adjusted before being sent to the TV wall to ensure that the media data sent to the TV wall matches the TV wall, ensuring that the adjusted media data can be correctly parsed by the TV wall, thereby ensuring the stability of media data playback.
