Notification method of multimedia device media source hot plug real-time notification system

technical field

The invention relates to a play system capable of remote control, in particular to a notification method of a real-time notification system for hot plugging of media sources of a multimedia device.

Background technique

Multimedia playback devices such as stereos and computers are essential electronic products for every family. When there are multiple playback devices, multiple controllers are required to control each playback device separately, which not only takes up space but also easily confuses each control. player corresponding to the playback device. Therefore, there is an application program, which can be installed in the controller to select which playback device to be remotely controlled. If the application program is installed in many controllers, each controller can control all playback devices. device.

In order to provide multiple playback modes, many multimedia playback devices provide more than one media source for users to choose from, such as network streaming data, data stored in itself, data from an external hard disk, and so on. If there are multiple controllers and playback devices, and they can communicate with each other to transmit data, the real-time performance of the data is very important. When the available media source of any playback device changes, if it cannot be known to all users in real time, the real-time performance of data communication between each playback device will be lost, so that the user cannot immediately know the available media source of the multimedia playback device changed.

Therefore, the present invention proposes a notification method for a real-time notification system for media source hot plugging of a multimedia device. The specific architecture and implementation thereof will be described in detail below:

detailed description

The present invention provides a notification method of a real-time notification system for hot plugging of media sources in multimedia devices. As shown in FIG. 10 is connected to the controller 12 through an access point 14 which is set in a wireless network 16 . The playback device 10 is a stereo, a wireless speaker, a broadcasting device, a music player or a computer, etc., and the controller 12 can be a smart phone, a tablet computer, a personal computer, etc., and a control program is installed in the controller 12, which can control the playback The application program of the device 10 remotely controls the playback device 10 through the access point 14 in the wireless network 16 .

2 is a block diagram of a controller corresponding to a single playback device in the present invention. The playback device 10 includes a plurality of receivers 102, a detection module 104, a processor 106 and a communication module 108. The receiver 102 can be wired. Jacks of USB, mini-USB or other specifications, or wireless multimedia receivers, can respectively receive a media source device 18; the detection module 104 is used to detect changes of the multiple receivers 102, such as whether a device is plugged in In the receiver 102, or whether there is a device removed from the receiver 102; the processor 106 is used to read and play the multimedia data in the media source device 18, and execute the instructions issued by the controller 12, when the receiver 102 is When inserted or removed, a hot-swapping message will be issued; the communication module 108 communicates with multiple controllers 12 simultaneously through the wireless network, transmits the hot-swapping information to the controllers 12, and can receive commands issued by the controllers 12 .

Include a communication module 122, a processor 124 and a display screen 126 in the controller 12, the display screen 126 is a touch screen, so the operation of the user on the display screen 126 will become instructions, through the processor 124 by the communication module 122 sent to the playback device 10. And if the playback device 10 sends the hot plug information, the communication module 122 will display the hot plug information on the display screen 126 after receiving the hot plug information.

Each media source device 18 has a detection element 182, and the detection element 182 can detect whether the media source device 18 itself has been inserted into the playback device 10 or removed from the playback device 10, and when detecting When an insertion or removal action is detected, the playback device 10 is actively notified, and the playback device 10 actively notifies the controller 12 that has joined the wireless network 16 through the wireless network 16 after receiving the notification from the media source device 18 . Therefore, not only a detection module 104 in the playback device 10 will detect the state of the receiver 102 , but the media source device 18 will also actively detect its insertion status and notify the playback device 10 .

Fig. 3 is a flowchart of an embodiment of a notification method in the present invention. In step S10, the playback device and the controller are powered on, and added to a designated wireless network including an access point. Each playback device can support more than two media source devices; when the playback device executes the user's control on it At the same time, each playback device will detect whether a media source device is inserted into it or removed from the playback device, as described in step S12. For example, when the playback device is playing the music of a CD, it will detect Whether there is a portable device plugged into the port; step S14, if it is found that a media source device is inserted or removed from the playback device, the playback device will actively send a hot plug message through the wireless network to the controller that has joined the wireless network; In step S16, after the controller receives the hot plug information, it will display it to the user on the display screen, so that the user can see the media source information of the playback device from the controller, and the user can also use the hot plug information according to the hot plug information. The information operation controller sends a control instruction to the playback device, as described in step S18. In this way, the user can control the playback device through the control interface of the control program installed in the controller.

For example, three users A, B, and C each hold a smart phone with a control program installed, and these three smart phones become three controllers I, J, K, and three playback devices X, Y, Z, each playback device X, Y, Z has three receivers, and the external media source device O, P, Q can be selected. User A adds the media source device O to the playback device X. At this time, the three controllers I, J, and K receive the audio source of the playback device X at the same time. The media source device O is added, and users A, B, and C can pass The controllers I, J, K operate the playback device X to switch the audio source to the media source device O. Assuming that the playback device Y is playing the media source P at this time, user B operates the controller J to remove the media source device P of the playback device Y, so that the controllers I, J, and K can all receive the media on the playback device Y The notification that the source device P is removed, at this time, the users A, B, and C can control the playback device Y to switch the media source to other media sources, such as the media source device Q, through their respective controllers I, J, and K.

To sum up, the notification method of the multimedia device media source hot plug real-time notification system provided by the present invention installs a detection module in the playback device, which can detect whether a media source device is inserted or removed, and whenever there is a media source When the device changes, it will send a hot plug information to notify the controller. After each controller receives the hot plug information, it can operate the playback device through the control program installed in the controller to select the audio source of the playback device. Therefore, when the media source device changes on any playback device, the user can obtain relevant information of the playback device in real time, and then perform corresponding operations immediately, such as playing, selecting a song, and selecting a media source.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the implementation scope of the present invention. Therefore, all equivalent changes or modifications based on the features and spirit described in the claims of the present invention shall be included in the protection scope of the present invention.
