20100008342 | OPTIMIZING IEEE 802.11 FOR TCIP/IP DATA TRANSFER - Systems and methods are described for increasing data transfer efficiency between networks. The invention being particularly well suited when establishing connectivity between wireless networks, such as based on IEEE 802 standards, and traditionally wired network protocols (often referred to as internet protocols), such as TCP/IP and UDP. The invention provides formatting of network packets and then processing of network packets according to one or more optimization processes. One optimization process comprises performing partial packet retransmissions to increase network efficiency, especially in high bit error rate networks such as wireless networks. Another optimization process comprises suppressing unnecessary packet acknowledgements, therein reducing burst traffic and saving substantial overhead in lossy networks. Additional aspects of the invention provide further benefits. The invention may be implemented within the MAC layer of a network interface, in particular within wireless network interfaces which are being increasingly utilized for both home and office short range interconnectivity. | 01-14-2010 |
20100182499 | MULTIMEDIA CONTENT DELIVERY USING PRE-STORED MULTIPLE DESCRIPTION CODED VIDEO WITH RESTART - An embodiment of the present invention includes a buffer, a selector, and an analyzer. The buffer stores at least a default stream coded by a multiple description (MD) coding and a restart stream coded by a predictive coding. The default and restart streams correspond to a media content. The selector selects a transmit frame from the default and restart streams according to a transmission status. The transmit frame is transmitted to a receiver. The analyzer provides the transmission status based on feedback information provided by the receiver. | 07-22-2010 |
