The method includes the steps of calling a service running supporting system after a unified authentication system receives on-demand information, verifying the user identity, the product information and the user subscription relation through the service running supporting system, generating on-demand request success information under the condition that the user identity, the product information and the user subscription relation are all correct, and generating authentication information according to the on-demand information through a digital copyright encryption system. A user inputs the on-demand information, the on-demand information is received by the unified authentication system, verified by the service running supporting system and then authenticated by the digital copyright encryption system so that authentication information can be formed, a product receiving terminal with configuration codes receives the authentication information and on-demand products according to the authentication information, the user can timely watch the on-demand products, and therefore the problems that the user can not conveniently watch the on-demand products and the utilization rate of satellite digital services is low due to the fact that no product on-demand services exist in existing satellite digital services are solved.

The invention relates to a blue light tester used for testing a lens. The blue light tester comprises a light source producing device, a blue light filtering detector, an amplifier, a driver and a digital display, wherein the light source producing device is used for producing a light source irradiating the lens, the blue light filtering detector is used for detecting the intensity of blue light in the light source passing through the lens and transmitting a detected intensity signal of the blue light to the amplifier, the amplifier amplifies the intensity signal of the blue light and transmits the intensity signal to the driver, the driver is connected with the digital display, and the digital display displays a numerical value of the lens with the blue light filtered. The blue light tester has the advantages of being low in cost and high in speed, resisting to the blue light, and displaying instantly, and a consumer can watch conveniently in time.

The four-way splicing type real-time panoramic imaging device of the invention relates to the image collection field, composed of four cameras, a camera fixing frame, a video server and a power supply; the four cameras are fixed on the camera fixing frame adjacently from end to end in mode of forming angles 90 degrees with each other; every camera is in communication connection with the video server through a data cable and is connected with the power supply circuit through a power cable; the video server is arranged at the far end; a processor, a memory and a communication module are mounted in the video server; the processor is respectively connected with every camera, the memory, the communication module and the power supply circuit. The four-way splicing type real-time panoramic imaging device of the invention uses independent video server 3, timely obtains the images photographed by the cameras of all directions, splices the images in real time, outputs the images through wire and wireless modes, is high in real time performance, enables a user to timely view and process the images and effectively saves manpower and time.

The embodiment of the invention provides a method and system for a webpage player to dynamically update total duration of a video and relates to the technical field of the articulated naturality web.According to the embodiment of the invention, a JS assembly reads video duration of a video resource from a video server; a player assembly reads the video duration of the video resource from the JS assembly and sets the video duration of the video resource according to the video duration; and the player assembly plays a video according to metadata and the video duration. The total duration of thevideo is dynamically updated through the JS assembly, so the problem that video fast forward and fast backward functions cannot be realized and new video segments only can be played by manually refreshing the player due to the fact that the player assembly cannot obtain the total duration of the video when a player plays a currently recorded video is solved, the video fast forward and fast backward can be carried out on the currently recorded video, and the user can watch the newly recorded video segments timely without refreshing the player.

The invention discloses a household storage cabinet convenient to install, relates to the technical field of storage cabinets, and aims at solving the problems that when an existing household storagecabinet is adopted to perform internal storage, dust prevention and privacy protection are almost conducted through a door plate, and dust prevention of a single door plate is single and lacks. A first door plate block is arranged on one side of the front end face of the storage cabinet outer main frame. A second door plate block is arranged on the other side of the front end surface of the storage cabinet outer main frame; one end of the first door plate block and one end of the second door plate block are each provided with a fixing rod column. The number of the fixing rod columns is two. Buffer cushion layers are arranged at the other end of the first door plate block and the other end of the second door plate block, the number of the buffer cushion layers is two, the two buffer cushionlayers are installed on the inner walls of the two ends of the storage cabinet outer main frame, handle grooves are formed in the first door plate block and the second door plate block, and the number of the handle grooves is two.

The invention provides an EPG information control device which comprises a receiving module, a storage module and a control module. The receiving module is configured to receive timing information andstatus information corresponding to each TS stream output port respectively. The memory module is used for storing the EPG information sent by the external equipment. A control module is respectivelyconnected with a receiving module and a storage module. At preset interval, the timing information corresponding to each TS stream output port is sequentially detected, For each TS stream output port, if it is detected that the EPG information corresponding to the starting address reaches the transmission time, A TS stream output port is judged to be in an idle state according to that state information, If the TS stream output port is in an idle state, the EPG information is inserted into the TS stream output by the TS stream output port, thereby alleviating the technical problem that the user in the prior art cannot watch the TV program in time, and achieving the technical effect that the user can watch the TV program in time.
