[0046] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0048] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0049] See Figure 1 This is a schematic diagram of the structure of a multimedia playback system in one embodiment.

[0050] In this embodiment, the multimedia playback system is applied in a smart home scenario. The multimedia playback system is used to play multimedia data, which includes audio and video data; such as... Figure 1 As shown, the multimedia playback system includes a first device and a second device. The first device is connected to the second device. The first device is used to run an audio and video service processing program, receive data from an audio and video source, and decode the audio and video data. The second device is used to receive the decoded audio and video data and play the audio and video.

[0051] When a user requests audio or video playback, the second device receives the audio / video on-demand instruction and notifies the first device. The first device then runs an audio / video service processing program, receives data from the audio / video source, and decodes the audio / video data. After decoding, the first device transmits the decoded data to the second device via the network. The second device receives the decoded audio / video data and plays the audio / video. This separation of multimedia data decoding and playback functions improves the high hardware requirements of multiple on-demand devices in scenarios where multiple devices are operating, thereby reducing usage costs. In whole-house smart home applications, there are typically multiple smart voice gateway devices in the house. These devices, equipped with audio / video on-demand functionality, need to decode and encode multimedia data. By dividing the work among these smart voice gateway devices, hardware costs can be further reduced.

[0070] Optionally, the method for determining the original file format of the target playback file may be obtained from the multimedia data source; the method for determining the target file format of the second device may be obtained based on the audio and video file formats supported by the second device.

[0071] The multimedia data intelligent on-demand method provided in this embodiment determines the original file format of the target playback file and the target file format of the second device; converts the original file format of the target playback file into a target data frame of the target file format; the first device runs an audio and video service processing program, receives data from the audio and video source, and decodes the audio and video data to generate an audio and video file format supported by the second device, thereby realizing the separation of multimedia data decoding and multimedia data playback functions.

[0076] Optionally, the method for obtaining the file description information of the local video-on-demand file may be derived by the multimedia data structure analysis unit in the first device.

[0077] Step 404: Send the file description information to the second device so that the second device can display a list of playable files to the user based on the file description information, so that the user can input the on-demand command based on the playable file list.

[0082] In this embodiment, as Figure 5 As shown, the specific steps preceding step 402 include steps 502 to 504.

[0083] Step 502: When the communication network between the first device and the multimedia data source is normal, detect whether there is a local on-demand file in the first device.

[0084] Optionally, the condition that the communication network between the first device and the multimedia data source is normal can mean that the network connection between the first device and the server storing the audio and video data is normal; the normal network connection can mean that the network bandwidth environment between the first device and the server storing the audio and video data meets the requirements for stable and fast transmission of multimedia data.

[0085] Optionally, the method for detecting whether a local on-demand file exists in the first device can be determined by a local on-demand file detection unit in the first device.

[0086] Step 504: If the local video-on-demand file does not exist, download the local video-on-demand file from the multimedia data source.

[0087] Optionally, if the local video-on-demand file does not exist, it may be that the local video-on-demand file is not stored in the first device; or it may be that the local video-on-demand file stored in the first device is abnormal.

[0090] Optionally, the first confirmation signal may be a feedback signal generated by the second device after receiving the file description information from the first device; specifically, the first confirmation signal may be in the form of an ACK (Acknowledge character) signal.

[0091] The intelligent on-demand method for multimedia data provided in this embodiment stops sending the file description information to the second device when a first confirmation signal is received from the second device within a preset time. The first confirmation signal is used to indicate that the second device has received the file description information. This improves the first device's perception of the second device, avoids the situation where the first device continuously sends the file description information to the second device, and saves the usage cost of the multimedia playback system.
