The invention discloses a multifunctional light-emitting diode (LED) device and a multifunctional loud speaker box system. The multifunctional LED device comprises an LED drive and power supply unit, a controller unit, an audio power amplifier unit, a loudspeaker unit, a wireless receiving and dispatching module and an LED light source assembly. The wireless receiving and dispatching module keeps in communication with a smart terminal, as well as communicates with other LED devices. The multifunctional loud speaker box system comprises a plurality of multifunctional LED devices and a smart terminal, wherein the smart terminal is capable of communicating with each multifunctional LED device, every two multifunctional LED devices are capable of communicating with each other, two multifunctional LED devices form a 2.0 sound track, and a 2.1 sound track, a 5.1 sound track or a 7.1 sound and the like can be configured as needed by adding configuration number of multifunctional LED devices. With no need in changing current arrangement of wire and without any additional equipment such as a wireless audio transmission studio camera, a remote control or a peripheral dimmer switch, the multifunctional LED device and the multifunctional loud speaker box system are convenient to use, support wireless dimmer and supply everyday illumination.

The invention provides a packing method for streaming media transmission in an intercom system. The method comprises the following steps of firstly, encoding acquired videos to acquire video frame of gradual single frames, and dividing the acquired audio PCM (pulse-code modulation) data into audio frame of gradual single frames according to appointed time period; secondly, after adding one data packet head to each video data packet and each audio data packet respectively, transmitting each video data packet and each audio data packet to a decoding terminal; and finally, analyzing the data packet head by the decoding terminal, wherein if the video data packet is lost, pausing until complete video key frames are received, if the audio data packet or audio frames are lost, automatically complementing the packet or the frames, and when video play is paused, if the audio frames or the audio data packet is not lost, the audio data can be normally played. The problems of much redundant data, mosaic videos and interrupted sound in a short time in a streaming media transmission process of the intercom system are solved, and the smoothness and the play effect of streaming media transmission in the intercom system are improved.

The invention discloses a multifunctional LED device and a multifunctional sound box system. The multifunctional LED device of the invention includes an LED drive and power supply unit, a controller unit, an audio amplifier unit, a speaker unit, a wireless transceiver module, and an LED light source assembly. The wireless transceiver module can not only maintain communication with the intelligent terminal, but also communicate with other LED devices. The multifunctional speaker system of the present invention includes a plurality of the above-mentioned multifunctional LED devices and an intelligent terminal. The intelligent terminal can communicate with each multifunctional LED device, and the multifunctional LED devices can also communicate with each other. Two multifunctional LED devices form 2.0 The channel can also be configured as 2.1 channel, 5.1 channel or 7.1 channel by increasing the number of multifunctional LED devices as required. The invention is easy to install and use, does not need to change the current wiring, does not need to add any wireless audio transmitter landline, remote control or peripheral dimming switch and other equipment, supports wireless dimming, and provides daily lighting.

The invention discloses a video list switching method, device and storage medium based on an education system. The method includes acquiring a plurality of video data and extracting video covers of the plurality of video data; generating a plurality of swiper plug-ins according to the plurality of video covers , store the video cover that needs to be displayed in the presentation layer, store the video cover that is not displayed in the buffer, and create an event monitoring layer; set the image style for the video cover of the presentation layer, and detect whether the video cover has video data; Set the switching transition effect between the video cover of the buffer and the video cover of the presentation layer; trigger the event of the event monitoring layer according to the button clicked by the user, and switch the video cover of the buffer to the presentation layer when the event is a switching event, and display The layer's video cover is switched to the buffer. The present invention satisfies the service requirements of multiple function points of the Tongtian Tower, and can ensure that the video can be played normally during the switching process, and has an animation effect, and no stuck switching will occur.
