Abstract: A method for transferring a picture image file from a transfer end to a receive end, comprising the following steps of: providing a first set of blocks at the transfer end; dividing the picture image file into a plurality of blocks at the transfer end; comparing the plurality of blocks with a first set of blocks to generate a correlation parameter for each block; determining whether the correlation parameter for each block is not less than a correlation threshold, and removing each of the blocks with the correlation parameter not less than the correlation threshold; generating a reconstruction information which records the linkage relationship between each of the plurality of blocks; transferring the plurality of blocks those are not removed and the reconstruction information to the receive end; and reconstructing the plurality of blocks into the picture image file based on the reconstruction information and a second set of blocks.

Abstract: A video conferencing signal processing system is disclosed. The video conferencing signal processing system comprises a receiver and a sender. An original video signal captured from the sender is capable of being processed into an encoded video conferencing signal by monitoring an output status of a video conferencing module of the receiver and processing the original video signal according to the output status of the receiver. The present invention reduces the consumption of system resources and the necessary transmitting bandwidth for video conferencing.

Abstract: An instant data sharing system is provided. The system comprises a user interface (UI) module, an instant communication module and a data sharing module. The UI module comprises a communication window and a presentation window and is used for operating the data sharing system by a user. The instant communication module establishes an instant communication with at least one remote host via a network, wherein the user performs the instant communication with the remote host via the communication window. The data sharing module is used for selecting a shared data, displaying the shared data on the presentation window and transmitting the shared data to the remote host. The data sharing module selects an encoding operation module to encode the shared data according to a type of the shared data, and transmits the encoded shared data to the remote host through a transmission module.

Abstract: A method and a system for instantly transmitting an interactive image are disclosed. The method is applied in a low bandwidth Internet connection for sharing the interactive image instantly between a first computer and a second computer. The image includes a main image and a track mark, and the track mark is generated by any one of the two computers.

Abstract: An image quality processing apparatus is disclosed. The apparatus includes an image module, a bandwidth detection module, an image control module, an image compression module and an image-outputting module. The image module receives an image. The bandwidth detection module detects a bandwidth of the internet. The image control module is coupled to the image module and the bandwidth detection module, determines the range of the bandwidth and issues a result according to the determined range. The image compression module compresses the image according to the result and generates a compressed image. The image-outputting module outputs the compressed image to the internet.
