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 present disclosure relates to a method, device, terminal and storage medium for playing video on a webpage, and belongs to the technical field of the Internet. The method includes: receiving coded video data, and determining the codec mode corresponding to the coded video data; if the codec mode is not supported by the video module preset in the browser, the The decoder pre-set in other application programs of the system decodes the encoded video data to obtain multiple decoded video frames; draws the video frames obtained through the decoding process on the canvas of the web page in the browser frame by frame. By adopting the present disclosure, the effect of playing video data normally can be realized.

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 is applicable to a three-dimensional (3D) television and provides a 3D display device and a display method. The device comprises a video decoding module, an image processing module and a video display module which are connected in series sequentially, and can display an image carried by a 3D information source on the video display module. The device also comprises a 3D image mode setting module which can automatically identify a signal transmitted by the video decoding module to the image processing module so as to acquire the 3D image mode of the 3D information source, and can set a signal transmitted by the image processing module to the video display module to be consistent with the 3D image mode. An automatic mode identification technology is adopted, so the television can play normally and can display the 3D effect normally in spite of the mode of a video source.

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 image data processing method and an apparatus thereof. The method is characterized by according to a current network state, adjusting a sending strategy of video image data stored in a shared buffer area, wherein the sending strategy is used for determining a frame loss proportion corresponding to the shared buffer area according to the current network state; and according to the sending strategy, sending the video image data. By using the technical scheme provided in the invention, an image can be played normally under the condition that a network environment is poor; normal data flow forwarding is realized and frame fluency is ensured.

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.
