Efficiently distributing video content using a combination of a peer-to-peer network and a content distribution network
InactiveUS20120297405A1Effective distributionEfficiently distributedTelevision conference systemsAnalogue secracy/subscription systemsContent distributionThe Internet
A method, system and computer program product for efficiently distributing video content. A peer-to-peer network and a content distribution network are used in combination to distribute video content. A content distribution network relies on servers distributed across the Internet to achieve high quality content delivery at a high cost. A peer-to-peer network distributes content among peers without incurring server side cost but may experience poor performance. The peer-to-peer network and the content distribution network are leveraged in a manner that achieves high content delivery and low cost by allowing the peer-to-peer network to serve as much content as possible while using the content distribution network to bootstrap the content in the peer-to-peer network and using it as a fallback whenever the peer-to-peer network has insufficient bandwidth, insufficient quality or when the missing piece of video content in the video buffer of the client device has an immediate deadline.

A system and method for using multiple peer listeners in order to improve the ability to receive a transmitted signal. A peer link is established between the peer listeners. At least some of the peer listeners also have a data link to a sender communicating with an outside source. In the simplest embodiment, a peer listener receiving data over the sender data link communicates that data to one or more other peers which may have an impaired ability to presently utilize its own data link to the sender. In more complex embodiments, multiple peer listeners can receive and process portions of needed data over the data link to the sender, then communicate portions of the data to other peer listeners on an as-needed basis.

The present invention demonstrates how network-coding can be applied to a deterministic broadcast approach, resulting in significant reductions in the number of transmissions in the network. We propose two algorithms, that rely only on local two-hop topology information and make extensive use of opportunistic listening to reduce the number of transmissions: 1) a simple XOR-based coding algorithm and 2) a Reed-Solomon based coding algorithm that determines the optimal coding gain achievable for a coding algorithm that relies only on local information.

Radio terminal, radio base station, channel signal forming method and channel signal receiving method
ActiveUS20110223926A1Quality improvementTransmission path divisionReceiver specific arrangementsZero paddingComputer terminal
A radio terminal, radio base station, channel signal forming method and channel signal receiving method wherein when an upstream unit band and a plurality of downstream unit bands associated therewith are used to perform communications, the quality of downstream assignment control information can be prevented from being degraded. In a base station (100), the PDCCH signals including upstream assignment control information are limited to ones that are placed in some of the downstream unit bands. This can reduce the probability of performance of zero padding to downstream assignment control information having greater importance. Also in the base station (100), the PDCCH signals of the downstream unit bands other than the basic unit band include only downstream resource assignment information. For this reason, in the individual regions of the downstream unit bands other than the basic unit band, the bandwidth of the downstream unit bands is always used as a reference of size adjustment and hence requires no information size adjustment. As a result, there is no need of performing zero padding to the downstream assignment control information, so that the quality of downstream assignment control information can be prevented from being degraded.
