Abstract: A system for remote monitoring and surveillance is disclosed in this invention. The system comprises a plurality of cameras, a router, and a server. The cameras are connected with the router separately through a wired or wireless communication protocol. The router is connected with the server through a wireless communication protocol. The cameras capture scenes and convert the captured scenes into a plurality of image signals. The router uses a communication protocol to connect with the cameras, and the router transmits the image signals by a first wireless communication protocol. The server receives the image signals by the first wireless communication protocol, processes the image signals to obtain first images, and displays the first images. A method for remote monitoring and surveillance is also disclosed in this invention.

Abstract: A compressor/decompressor (Codec) selecting apparatus includes a performance analyzer, a training server, a storage unit, and a selecting unit. The performance analyzer analyzes the performance of the current internet communication system, and outputs environmental parameters accordingly. The training server obtains learning data corresponding to a hyperplane according to training samples. The storage unit stores the learning data and the related parameters. The selecting unit does a functional analysis according to the environmental parameters and the learning data in order to select the Codec suitable for the current internet communication system.

Abstract: A system for video transmission using 3G mobile network includes a mobile video transmitter and a server. The mobile video transmitter is capable of transmitting a plurality of video packets via a plurality of uplink channels of the 3G mobile network. The mobile video transmitter includes a data splitter that is capable of splitting the video packets; a plurality of transmitting devices coupled to the data splitter, each of the transmitting devices having a transceiver. The data splitter assigns the video packets to the transmitting devices using a water filling method such that the video packets waiting for lo transmission in each of the transmitting devices are equal. The server receiving the video packets via the 3G mobile network is capable of sequencing and combining the video packets into a video signal. A method using the foregoing system for video transmission using 3G mobile network is also provided.
