Abstract: A method for optimizing a process of displaying video streams with specified event receives video streams. The video streams are sequenced based on a specified arrangement role to from a video stream queue. By analyzing each video streams, whether each video stream includes a specified event is determined. If each video stream without the specified event, the video streams are outputted based on the video stream queue. If the video stream includes the specified event, the video stream with the specified event is adjusted to be priority in the video stream queue, and the video streams are outputted based on the updated video stream queue. The video streams with the specified event can be prioritized processed and focus. A video stream processing apparatus and a computer readable storage medium applying the method are also provided.

Abstract: A method of controlling a box for cultivating plants, to adapt the box environment to the current state of growth of the plant being cultivated. The brightness and wavelengths of the lighting, and other relevant conditions of the box, are controlled according to multiple sets of parameters for growth of such plants, at multiple stages. Images of the plant and information as to the actual illumination in the box are obtained from time to time. The method further analyzes a degree of change and thus growth of the plant based on the images. The method also supplies backup systems for the lighting and other types of service to the plant, to be activated when real-time calculations, based on the growth history of each plant and its current state, indicate accordingly parameter plant selected from the multiple sets of parameters. A plant cultivation system is also disclosed.

Abstract: A plant growth monitoring method includes sensing growth data of a plant, determining reference data of the growth data, determining a first effective range of an N number of parameters of the reference data, determining a second effecting range of each parameter, and obtaining standard values of the N number of parameters in each of T growth periods.

Abstract: In an IP camera control method, a web server transmits a show page, on which a control panel is displayed, to an electronic terminal, and then an IP camera is controlled according to a touch operation on the control panel of the electronic terminal.

Abstract: A method of playing a network video using an electronic device includes acquiring a web address of the network video from a browser, and transmitting the acquired web address to the web server. When the browser does not support a Motion Joint Photographic Experts Group (MJPEG) format, a static image frame is established. The method further transmits the acquired web address to the web server and requesting a transmission of each single static image from the web server. The method further receives each single static image from the web server and generates a video file comprising a plurality of single static images by adding the received each single static image into the established static image frame. The method further displays the single static images successively in the browser to play the network video.

Abstract: In a method for playing real-images in a virtual reality using an electronic device, the method generates a request for obtaining a real-time image of a scene and notifies a Virtual Reality(VR) client to send the request to a web sever to obtain the real-time image. The real-time image is cut into a sequence of static pictures by the web server, and is sent to the VR client through a network. The method triggers the VR client to play each of the sequence of static pictures to present the real-time image on a display screen of the electronic device.
