Abstract: An electronic confidential document viewing method is performed by an electronic device in electronic communication with a pair of eyeglasses. In response to display a confidential document on a display device, a protection image is generated based on a security image of the confidential document. The protection image is a copy of the security image that is offset from the security image by a predetermined distance in a vertical direction or a horizontal direction. The security image and the protection image are synchronously transmitted to the display device. The display device displays an overlapping picture based on the two images. The eyeglasses receive the overlapping picture, and separate the overlapping picture into two images. One of the two images is viewable by the left eye of a viewer, and another image is viewable by the right eye of the viewer.

The method further obtains a plurality of hash addresses of the plurality of key segments corresponding to the plurality of hash functions, stores information of the data storage structure of each key segment in a hash table according to the hash address of the key segment corresponding to one of the hash functions.

Abstract: A method embeds product information in videos with product placements using an electronic device. The electronic device converts product information of products into advertisement information, and saves the advertisement information in an ad database. The advertisement information includes product images and advertisements of the products. The electronic device exports the advertisement of a presented product displayed on a display device from the ad database according to the product images during the video broadcasts. The advertisement of the presented product is displayed on the display device.

Abstract: A method embeds product information in TV programs with product placements using an electronic device. The electronic device defines keywords and advertising information of products presented on a TV program, and further defines appearance times of the keywords according to product presented times. During the TV program broadcasts, the electronic device currently displays the keywords and the presented products on a display device according to the appearance times, receives a selection operation on a product presented on the display device, exports the advertising information of the selected product. The advertising information is displayed on the display device.

Abstract: A method searches product information in TV programs with product placements using an electronic device. The electronic device encloses presented products of the TV program in a graphic box, and defines keywords related to the presented products. During the TV program broadcasts, the electronic device receives a selection operation on a product displayed on a display device, and uses a search engine to search for related information of the selected product according to keywords. The searched information is displayed on the display device for users to browse.

Abstract: A method searches product information in TV programs with product placements using an electronic device. The electronic device defines keywords and appearance times of products presented on a TV program. During the TV program broadcasts, the electronic device displays the keywords of the presented products on a display device according to the predetermined appearance times. A product is selected from the presented products after any of the keyword presented on the TV program is tapped. The electronic device uses a search engine to search for related information of the selected product according to the tapped keyword, and displays the searched information on the display device for users to browse.

Abstract: A method for seeking a file position of a file first seeks an estimated file position corresponding to a specified time point in the file, and adjusts the estimated file position according to a preset estimation formula. The method further determines the estimated file position is an accurate file position of the specified time point in the file until a difference between the estimated file position and the specified time point is less than a preset value.

Abstract: A method for storing node information of a Huffman tree. The method creates an index of each node in the Huffman tree using a breadth first search (BFS) algorithm. The method further reads each node of the Huffman tree beginning from a root node according to a sequence of the index of each node, and stores node information of each node into an array of the Huffman tree.

Abstract: A file decoding method uses a master server to decode multimedia files. The method records statuses of a plurality of slave servers in a status table, receives a decoding request to decode the multimedia file from a web server, and selects one slave server from the status table to process the decoding request by the master server. The method further sends an Internet protocol (IP) address of the selected slave server to a web browser by the web server, sends a decoding command to the selected slave server by the web browser, decodes the multimedia file by the selected slave server, and transmits decoded data of the multimedia file to the web browser.
