Abstract: Disclosed herein are a method for successively displaying sections of a screen and a corresponding computer-readable medium. The method comprises loading the screen, transforming a section of the screen to which a starting point on the screen corresponds into a starting sub-screen, transforming a section of the screen to which a selected ending point on the screen corresponds into an ending sub-screen, and transforming sections of the screen to which a selected plurality of midway points on the screen correspond into midway sub-screens. The points collectively correspond to a time sequence, based on which the sub-screens are sequentially displayed. The present invention enables digital mechanisms that capture and sequentially display parts of a wide-angle image to approximate the shifting motion of the human eye or mechanical PTZ cameras in response to changing observing angles of view.

Abstract: An audio-video processing method is adapted to an audio-video device and a storage device for processing an index-based audio-video file. The method for processing audio-video data includes a write procedure, a play procedure, and/or a repair procedure. In the write procedure, audio-video data is captured by the audio-video device first, and the audio-video data includes a plurality of continuous samples; a header is written according to the audio-video data; a predetermined number of samples are captured as a data chunk; a prefix index corresponding to the data chunk and the data chunk are written in sequence repeatedly according to the audio-video data; and a file index is written finally. In the play procedure, after the header is read, corresponding prefix index and data chunk are repeatedly read and played. Moreover, in the repair procedure, incompletely written file index and data chunk are repaired through all the prefix indexes.

Abstract: A method for analyzing a network environment, is provided. First acquiring a plurality of connection data of all network cards of a terminal device is performed. Then, according to connection data, determining whether or not a terminal device uses a PPPoE connection to connect to a network system. Finally, determining whether or not an IP address of the terminal device is a public IP address and determining whether or not the terminal device uses DHCP to acquire a target IP address.

Abstract: A method for analyzing a network environment, in which the method comprises the following steps: Acquiring a plurality of connection data of all network cards of a terminal device; according to connection data, determining whether or not a terminal device uses a PPPoEconnection is used to connect to a network system; determining whether or not an IP address of the terminal device is a public IP address and determining whether or not the terminal device uses DHCP to acquire a target IP address.

Abstract: The present invention provides a method for connecting with a wireless network device. The method includes following steps: upon configuring the wireless network device, executing a first target procedure to connect the wireless network device with the terminal device; executing a second target procedure, allowing the sharing device to be searched by the wireless network device according to at least one target signal; executing a third target procedure to select a target sharing device corresponding to the wireless network device according to the target signal; and connecting wirelessly the wireless network device with the target sharing device.

Abstract: A method and devices for linking an audiovisual capture device, which enable an operator to use a terminal device at his end to locate an audiovisual capture device installed at another end through a network architecture, thereby facilitating the Implementation of the subsequent installation and setting operations. The method includes: execution of a first processing procedure by the audiovisual capture device, and execution of a second processing procedure by the terminal device. After the two processing procedures have been completed, the information linking is effected between the terminal device and the audiovisual capture device, which enables the operator to use the terminal device to execute installation and setting up of the audiovisual capture device.
