Abstract: A method of assisting a first player of a videogame is provided. The method includes making a game state of the first player accessible to a second player. The game state describes a state of the videogame as played by the first player. The method also includes executing the videogame for the second player using the game state of the first player to define the initial state of the videogame for the second player, allowing the second player to play the videogame based upon the game state of the first player until a first predetermined criterion is met, and providing to the first player data for updating their game state in response to the play of the second player.

Abstract: An entertainment device comprises a display generator arranged to generate for display a representation of an on-line virtual environment corresponding to a first instance of a plurality of substantially similar on-line virtual environments and to generate for display within the representation of the on-line virtual environment an avatar controlled by the user of the entertainment device and one or more software-controlled avatars; a data communications arrangement operable to transmit an alert signal in response to a predetermined action of the user of the entertainment device within the first instance of the on-line virtual environment, said signal serving to request interaction with a human operator, the data communications arrangement being further operable to receive a notification signal; the display generator being arranged to respond to the notification signal by changing the mode of a software controlled avatar to represent an additional user of another entertainment device in data communication with

Abstract: An entertainment device comprises communication means for communicating with a remote device over a network; program code and resources for running a full version of the program, the program code being operable to interact with remote devices also running a full version of the program; and program resource classification means, and in which when communication with a remote device indicates that the remote device is running a demonstration version of the program code; the program code on the entertainment device restricts the use of program resources to those identified by the program resource classification means as being available to or compatible with the demonstration version of the program, thereby restricting the full version of the program to operate substantially as a demo version of the program for the purposes of interaction with a demo version of the program being run on the remote device.

Abstract: A server for administering an on-line virtual environment comprises a data communication arrangement and a processor. The data communication arrangement receives a signal from a first entertainment device in communication with an instance of the virtual environment. The signal indicates that a user of that device has performed a predetermined action. The processor determines the availability of a second entertainment device, and is operable to switch the second device from a second instance of the virtual environment to the first instance of the virtual environment. The data communication arrangement is operable, if the second device is available, to transmit a signal to the first device indicating that a software controlled avatar within that instance should change modes to represent a user of the second device. The processor is operable to transfer control of a previously software controlled avatar within that instance of the virtual environment to the second device.

Abstract: A method of processing a speech signal in noise, comprising: determining a frequency spectrum of a frame of the speech signal; determining a value of the pitch of the frame of the speech signal; identifying peakes (12, 14, 16, 22, 28, 32) in the spectrum; and evaluating the peaks individually to determine respective scores for the peaks, the score for a peak being a measure of the likelihood that the peak is a harmonic band of teh speech signal. As a consequence there is: (a) no need for high f0 accuracy as there is no need to predict long sequences of harmonic positions; and (b) no need for an assumption of harmonic integrity at all points.
