Abstract: An audio-video synchronization method is executable in a video conference device. The method includes determining a first presence time of a predetermined visual effect in a captured video sample stream and a second presence time of a predetermined sound effect in a captured audio sample stream, calculating a time difference between the first and second presence time, and adjusting timestamps of each real-time transport protocol packet in an audio stream sent out by the video conference apparatus based on the time difference. The method further includes receiving an adjustment value from an user input, and adjusting timestamps of each real-time transport protocol packet in an audio stream received by the video conference apparatus based on the adjustment value.

Abstract: A mobile terminal connects to a wireless access point (AP) connected to a web server to retrieve and display a list of uniform resource locators (URLs) corresponding to types of multimedia content stored in a multimedia server. Each URL includes a channel identifier allocated to a corresponding type of the multimedia content. After receiving a selection of one URL, the mobile terminal parses the selected URL to retrieve a channel identifier, and automatically switches to a channel corresponding to the channel identifier. The mobile terminal connects to a wireless AP on the channel to retrieve a corresponding type of the multimedia content from the multimedia server.

Abstract: An Internet protocol (IP) phone establishes a voice communication with a remote IP phone, and establishes a desktop sharing connection with the remote IP phone upon a sharing key being pressed. The IP phone captures local desktop display data of a local computer, and transmits the local desktop display data to the remote IP phone over the Internet. The IP phone receives remote desktop display data of a remote computer from the remote IP phone over the Internet, and outputs the remote desktop display data to the local computer to display the remote desktop display data on the local computer.

Abstract: A mobile terminal device detects current communication environment status of the device and calculates a value of a radio quality index (RQI), and adjusts the roaming threshold according to the value of the RQI. The device further calculates a value of a user movement index (UMI) and adjusts the frequency of the device for scanning object access points. After determining the object access point that has satisfied a roaming threshold, the device ends the communication between the device and the current access point, and establishes a communication between the device and the object access point.

Abstract: A device for realizing on screen display (OSD) in video signals includes a comparator (430) and an outputting control unit (440). The comparator (430) is used for receiving OSD signals and identification signals on a background color selected to be transparent in the OSD signals, identifying the background color in the OSD signals based on the identification signals, and generating a control signal based on the identification. The outputting control unit (440) is connected to the comparator (430), and is used for receiving UV components of the OSD signals, UV components of the video signals, and the control signal, and for selectively outputting UV data of the video signals or UV data of the OSD signals according to the control signal. The device simulates translucent OSD by preparing the Y and UV components of displayable YUV signals respectively from the video signals and the OSD signals.

The system includes a plurality of message providers (1), an alert server (2), and a plurality of message receivers (4). The message providers and the message receivers are linked to the alert server via a communication network (3). The alert server includes a first database (20), an application (21), and a second database (22). The first database receives various messages provided by the message providers. The application generates an alert signal for each message, and sends the generated alert signals and corresponding messages in that order to corresponding message receivers. The message receivers receive the alert signals and corresponding messages in that order, and send respective receipts to the alert server in corresponding order. The second database stores messages that have accompanying alert signals.
