All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, a passenger entertainment system in an intelligent cabin has fewer functions of multi-screen synchronous playing, and the problems of playing blockage and the like are easily caused due to more consumed flow of the existing passenger entertainment system. The invention adopts a vehicle-mounted dual-mode multi-zone multimedia playing method, a vehicle-mounted dual-mode multi-zone multimedia playing system and a vehicle-mounted dual-mode multi-zone multimedia playing device, and can realize a decentralized multimedia playing network, thereby improving the entertainment experience of personnel in a vehicle.
Referring to fig. 1, fig. 1 shows a system architecture scenario diagram, which includes a car machine 110 and a plurality of multimedia nodes 120, where the car machine includes a node connection module 130 and a multimedia acquisition module 140. The multimedia node 120 includes a screen, a speaker, and the like. The multimedia nodes 120 are respectively registered in the car machine 110 network and form a multimedia node 120 distribution network, and the registration process may be that the multimedia nodes 120 are registered in the car machine 110 network and respectively send information with other multimedia nodes 120 to realize node discovery. After other multimedia nodes 120 are discovered, a plurality of multimedia nodes 120 may form a multimedia node 120 distribution network. When the in-vehicle personnel select to play the multimedia file individually using the multimedia node 120, the multimedia node 120 may receive an individual play instruction, pull the video stream or the audio stream from the network or the local multimedia library through the in-vehicle device 110, and the in-vehicle device 110 pushes the video stream or the audio stream to the multimedia node 120 for playing. When the vehicle interior personnel select to use the multiple multimedia nodes 120 to play the multimedia files synchronously, the sharing multimedia node 120 may serve as a multimedia master node, control other multimedia nodes 120 to serve as multimedia slave nodes to play the multimedia files simultaneously, the multimedia master node and the multimedia slave nodes pull video streams or audio streams from a network or a local multimedia library through the vehicle machine 110 at the same time, and the vehicle machine 110 pushes the video streams or the audio streams to the multiple multimedia nodes 120 to play. Through the operation of the multimedia master node, the synchronous playing of the multimedia slave nodes and the multimedia slave nodes can be realized, a decentralized multimedia node 120 distribution network is formed, the multi-screen synchronous playing is realized, and the entertainment experience of people in the vehicle is effectively improved. The multimedia nodes in the invention can be used as a multimedia master node and a multimedia slave node.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for vehicle-mounted dual-mode multi-zone multimedia playing according to an embodiment of the invention.
As shown in fig. 2, according to a flowchart of a method for in-vehicle dual-mode multi-zone multimedia playing, the flowchart includes S210-S240, and several steps are described in detail below:
and S210, registering the multimedia node in the vehicle.
Specifically, the multimedia node may include devices such as a display screen, a speaker, a headphone headrest, and the like in the in-vehicle passenger entertainment system, and the multimedia node is registered by a Daemon process of the in-vehicle machine before playing multimedia, where the Daemon process is also called a Daemon process (Daemon), and is a special process running in the background, which is independent of the control terminal, and periodically performs some task or waits for some event to occur. In the embodiment of the invention, the daemon process is used for receiving the registration of the multimedia nodes to form the multimedia node distribution network, and the daemon process is independent of the control terminal, so that the daemon process is used for receiving the registration of the multimedia nodes and can not interfere with other programs.
S220, a plurality of multimedia nodes form a multimedia node distribution network.
Specifically, after registration, the multimedia nodes communicate with each other to discover other multimedia nodes and form a multimedia node distribution network. More specifically, the multimedia node distribution network is a decentralized network, and any one multimedia node can be used as a multimedia master node to share content when a multimedia file needs to be played synchronously with other multimedia nodes in the network. With the decentralized feature, each multimedia node in the multimedia node distribution network has a highly autonomous nature and plays synchronously when needed. Thus, a highly customized entertainment experience may be provided for the occupants of the vehicle.
And S230, independently playing the multimedia node.
Specifically, when a passenger in a car selects to play independently, the multimedia node sends an independent play request to a daemon process of the car machine after receiving an independent play instruction, the daemon process pulls a video stream or an audio stream from a local multimedia library or a network of the car machine after receiving the request, pushes the pulled video stream or audio stream to the multimedia node, and the multimedia node decodes the video stream or the audio stream and plays the decoded video stream or audio stream.
And S240, the multimedia master node controls the multimedia slave nodes to play synchronously.
Specifically, when the in-car passenger selects to share the playing content, the in-car passenger can synchronously play the content through the multimedia node in use. For example, after the multimedia node receives the synchronous playing instruction, the multimedia node serves as a multimedia master node, other multimedia nodes serve as multimedia slave nodes, the multimedia master node sends a synchronous playing request to a daemon process, the car machine initiates a sharing request to the multimedia slave nodes through the daemon process, and when a passenger in a car refuses the sharing request through the multimedia slave nodes, synchronous playing cannot be performed. When the passengers in the vehicle agree to the sharing request through the multimedia slave nodes, the daemon process pulls the video stream or the audio stream from the local multimedia library or the network of the vehicle machine and respectively pushes the pulled video stream or audio stream to the multimedia master node, and the multimedia master node and the multimedia slave nodes decode and play the video stream or the audio stream. Through the decentralized multimedia node distribution network, passengers in the vehicle can play synchronously by taking any multimedia node as a main node, so that the entertainment experience of the passengers in the vehicle is improved. In addition, when synchronous playing is carried out, the daemon process only needs to pull stream once from the network and push the stream to a plurality of multimedia nodes, thereby effectively saving the flow and improving the bandwidth utilization rate.
More specifically, when synchronous playing is performed, the multimedia master node sends clocks to the multimedia slave nodes at regular time for synchronization, and each multimedia slave node performs playing according to the clocks, so that synchronous playing can be ensured. In addition, each multimedia node can resample the audio to adjust the audio in corresponding time, and the volume, the audio duration and the like can be adjusted when the audio is adjusted, so that the audio and the played video can be synchronously output. Thereby, a further audio synchronization is achieved.
In another aspect, the present invention provides a system for vehicle-mounted dual-mode multi-zone multimedia playing, and fig. 3 is a schematic structural diagram of the system for vehicle-mounted dual-mode multi-zone multimedia playing, including: multimedia node 310, car machine 320.

the car machine 320 is used for providing multimedia files to the multimedia node 310;
further, a plurality of multimedia nodes 310 are respectively registered in the car machine 320 network and establish a multimedia node 310 distribution network. By establishing a decentralized multimedia node 310 distribution network, any multimedia node 310 in the network can share multimedia files as a master node to other multimedia nodes 310 as slave nodes. Therefore, the entertainment experience of people in the vehicle is improved.
Further, the multimedia slave node is a multimedia node 310 other than the multimedia master node.
