Method and system for selecting interpolation filter type in video coding

Abstract: A method and system for coding a video sequence based on motion compensated prediction (642), wherein an interpolation filter (640) is used to generate predicted pixel values for picture blocks in the video sequence. The interpolation filter for use in conjunction with a multi-picture type is shorter or having fewer coefficients than the interpolation filter for use in conjunction with a single-picture type. As such, the complexity of the interpolation filter for the multi-picture type can be reduced. Furthermore, the interpolation filter may be changed based on the characteristics of the block, the size and/or the shape of the block.

Method and apparatus for hover-based spatial searches on mobile maps

Abstract: An approach is provided for enabling hover-based interactions to define spatial searches on mobile maps. A user interaction manager causes, at least in part, a rendering of at least one user interface depicting mapping information. A user interaction manager then processes and/or facilitates a processing of one or more hover-based interactions with the at least one user interface to determine one or more parameters for one or more spatial searches over the mapping information.

Method and apparatus for controlling transmission power of a radio transmitter

Abstract: A method for controlling transmission power of a radio transmitter in a cellular communications system, such as in a CDMA-system, which includes determining a reference value (SIR m ) indicating the quality of the signals received from the radiotransmitter, determining a reference value (P m , SIR pm ) indicating the current traffic load in the radiocell, and commanding the radio transmitter to adjust transmission power. In order to improve speed and reliability during any traffic conditions the method includes comparing both the reference value (SIR m ) for the quality of the received signals, and the reference value (P m , SIR pm ) for the traffic load with predetermined target values (SIR t , P t , SIR pt ), and practicing the commanding of the radio transmitter to adjust its transmission power depending on the result of the comparison.

Preventing misuse of a copied subscriber identity in a mobile communication system

Abstract: The invention relates to a method and an equipment of preventing the misuse of a copied subscriber identity in a mobile communication system. The use of a subscriber identity (IMSI) is restricted to predetermined terminals (MS), each having an associated equipment identity (IMEI) in such a way that: a number of allowable equipment identities (IMEI) is defined for at least one subscriber identity (IMSI), and a data base (60) linking said subscriber identities (IMSI) and the equipment identities (IMSI) allowable to them is created; the terminal (MS) sends the terminal user subscriber identity (IMSI) and its dedicated equipment identity (IMEI) to the rest of the system; the rest of the system compares whether the equipment identity (IMEI) sent is allowable to the subscriber identity (IMSI) sent; as a response to the equipment identity (IMEI) sent being allowable to the subscriber identity (IMSI) sent, the use of the terminal (MS) is permitted, and otherwise the use is denied.

Systems and methods for characterizing television preferences over a wireless network

Abstract: A system for interacting with viewers of television programming includes a television set and a network terminal for each such user. The terminals are connected by the network to an interactive server which maintains a first database of persistent information for each user and a second database of current preference information for each user. The current preference information includes registrations of users as viewing particular programs or as participating in certain activities chronicled in television programs, such as lotteries, polls, and product promotions. According to information in the first and second databases and according to current user requests, the interactive server forwards information to users' terminals, modifies content of all television programming, or modifies content of television programming, targeted to certain users or groups of users for selection by those users cable or satellite set-top boxes.
