IPC: H04N7/173
Filed: 2008-01-31
Abstract: A method and apparatus for distributing media over a P2P IPTV network is described. Media frames of a subscribed media channel are received at a peer node in the network. Meta data is sent from selected other peer nodes in the network to the peer node. The meta data includes media channel subscription information of the selected other peer nodes. When user instructions are received to change the subscribed media channel to a new channel, the meta data is used to determine whether any of the selected other peer nodes are subscribed to the new channel.

Title: Video encoding and decoding with improved error resilience
Inventor: LAROCHE GUILLAUME
IPC: H04N19/89
Filed: 2010-12-29
Abstract: In motion vector competition (MVCOMP) video encoding schemes, the residual motion vector and the index of the chosen motion value predictor vector are encoded for each block. The number of bits required to encode the index may be reduced when some of the predictors are the same or when it is possible to eliminate candidates from knowledge of the motion vector residual and the encoderâ  s cost optimization criterion. This bit-reducing method is however very vulnerable to transmission errors because the number of index encoding bits depends on the motion vector predictor values. To counteract this problem entropic encoding is used for encoding the residual motion vector and the index when bitstream losses or motion activity is low, but when losses or motion activity are higher a more robust but less efficient encoding scheme such as unary encoding is used, the selected encoding mode being transmitted as a flag bit in the bitstream.

Title: Golf ball marking stencil and method of use
Inventor: KRIKORIAN RAND J
IPC: A63B45/02
Filed: 2009-10-15
Abstract: A golf ball marking stencil includes two caps, resiliently biased toward one another, configured as spherical segments defining a cavity therebetween to securely retain a golf ball. Stencil slots for marking putt alignment path, putter face squareness and swing path lines are defined in the caps. Actuator tabs project from the caps and may be pinched together in opposition to a bias spring to force the caps open to expose the cavity. The spring force of the bias spring prevents movement of a retained golf ball relative to the caps. The cavity periphery is contoured to permit a marker pen to be engaged therein when the cavity does not contain a golf ball.

Title: Wireless communications wherein modulation schemes for dominant interfering devices are selected to both use real symbols or complex symbols
Inventor: LAMPINEN KARL MARKO JUHANI
IPC: H04L1/00
Filed: 2012-05-31
Abstract: A wireless network wherein access points (AP)/base stations and mobile terminals select modulation schemes such that a wanted signal and a dominant interfering signal both use real valued modulation or both use complex valued modulation. Matching modulation types may improve interference rejection capabilities (IRC). The communications may be between APs and terminal devices (uplink/downlink) or may be between terminal devices (D2D). A mobile terminal may determine the type of interference that it is subjected to (real/complex) and may then request that an AP use the same type of modulation for communication 40. The AP may then make a determination 42 about whether to use real/complex valued modulation and communicate 46 on that basis. Access points/cells may also advise each other of modulation schemes to be employed and thereby co-ordinate the selection of modulation schemes to achieve all real/complex signals and interference. Selection of modulation schemes may also involve path loss information and signal to interference and noise ratios (SINR).
