Abstract: A system of multimodality-appended rich media comments is provided. The system includes a server and an electronic device. The electronic device includes a network access module, at least one sensor and a processing unit. The network access module communicates with the server. The at least one sensor senses a user's behavior in a recording mode to obtain a sensing data. The processing unit performs an application to provide a source medium, wherein a rich media comment function of the application can be activated to provide multiple interactive objects for selection and then trigger the recording mode. The application uploads the sensing data to the server after the recording mode finishes. The server analyzes the sensing data and accordingly modifies the selected interactive object, combines the source medium with the modified interactive object into a rendered medium, and then delivers the rendered medium to the application.

Abstract: The invention discloses an event announcing system. The event announcing system comprises a portable electrical apparatus, a network, and a server. The portable electrical apparatus comprises an image capturing module, a positioning module, a time module, and a processing module. When the image capturing module captures an image information related to an event, the positioning module receives a positioning information and the time module receives a time information. The processing module is used for generating an announcing signal according to the image information, the positioning information, and the time information. When the server receives the announcing signal via the network, the server validates the announcing signal according to a validating rule and selectively generates an event report according to the announcing signal.

Abstract: A voice/video communication system is disclosed. The system includes a caller having a first PSTN subsystem and a first data subsystem, and a callee, wherein the first data subsystem encodes the caller's public IP address/port into a first key sequence and triggers the first PSTN system to send first audio coding representing the first key sequence to the callee.

Abstract: The invention discloses a communication system for assisting a user for retrieving geography-associated multimedia information, and the communication system comprises a data processing device and several mobile communication devices. The data processing device receives a first request information including a location term and a time term from a terminal device of the user, and broadcasting a second request information, based on the time term, to the mobile communication devices located within a region relative to the location term. The data processing device receives responding messages and captured audio and/or video data from the mobile communication devices accepting the second request information, and transmitting a location-related information to the terminal device based on the responding messages. The user transmits responding information responsive to the location-related information to the data processing device via the terminal device.
