Abstract: Apparatus and method for packet redundancy and recovery are disclosed. In a transmitter, parity packets are generated by executing exclusive OR between the corresponding data packets, and are transmitted along with the data packets to a receiver. In the receiver, lost data packets are found out and are recovered by executing exclusive OR between the corresponding data packets and the corresponding parity packets. This invention enhances the reliability of streaming data transmission using loss-recovery packets. Data packets are grouped and transmitted with redundant packets to allow the receiver to recover a lost packet within the group. This will minimize the need and therefore the time and delay to request a retransmission of the damaged or lost packets.

Abstract: The present invention provides at least an electronic system for network conference. The electronic system includes a user right module for storing and maintaining a plurality of user rights associated to each user of the electronic system, and a meeting right module for creating a meeting having a plurality of meeting rights according to associated user rights of a meeting creator. A participant right module is presented for determining a plurality of participant rights according to the plurality of meeting rights of the meeting and the associated user rights of a participant of the meeting. The system includes a plurality of participant client modules for receiving and sending media stream according to the plurality of participant rights of corresponding participant, and a matrix module for processing and distributing media stream to and from the plurality of participant client modules according to the plurality of participant rights.

Abstract: A system for sharing display information comprising a network apparatus for connecting to a receiver of display information, and a memory for storing at least one program, a first graphics driver, a second graphics driver, and a network sharing program. A processor configured to execute the program, the first graphics driver, and the second graphics driver stored in the memory. The program is executed for generating display information to the first graphics driver. The first graphics driver is executed for forwarding display information to the second graphics driver and the network sharing program. The network sharing program is executed for processing display information and for sending the processed display information to the receiver through the network apparatus. The second graphics driver is executed for translating display information. The system also includes a graphics apparatus for generating display information of a whole desktop according to display information sent from the second graphics driver.
