Abstract: A method and means for self-policing and automatically rate-limiting multiple-user online forums. The preferred embodiment of the invention includes a set of rules that permit users to censure other users. A censured user has one or more “privileges” (which may include access to the online computer system or the effective message rate of a communications connection) taken away or diminished; the privilege is gradually restored if the censured user behaves. The censuring participant and other pertinent participants are notified of the effect of the censuring on the censured user. In another aspect of the invention, the online computer system automatically tracks the rate at which a user sends certain types of messages, and can message rate limit a user who uses too many system resources by sending a large number of messages in rapid succession.

Abstract: Informing a first network user of activity by other network users includes providing an instant messaging user interface. The instant messaging user interface includes a list of two or more network users selected by the first network user. The list shows presence information for at least a first selected network user and a second selected network user. The instant messaging user interface also includes distinct visual identifiers that are respectively associated with the first selected network user and the second selected network user on the instant messaging user interface and that each indicate television programming being viewed by the selected network user with which they are associated.

Abstract: Systems and techniques for displaying an image sent between subscribers of a communications system by receiving electronic data corresponding to the image; displaying a blurred view of the image; and gradually displaying a sharper version of the image in response to user input.

Abstract: A method of interfacing used on a network having a central computer system and a plurality of remote computer system is provided. Each remote computer system includes a video display. The method includes the steps of creating a first visual representation of a first user on the visual display of the first computer system and a second visual representation of a second user on the visual display of the second computer system. The second visual representation is then displayed on the visual display of the first computer system and the first visual representation is displayed on the video display of the second computer system.

Abstract: Communicating with and/or monitoring of a targeted used in computer-network environment (e.g., an instant messaging system) involves detecting that the targeted user has signed on to the network, and upon detecting the signon, automatically communicating with the targeted user, for example, by sending an instant message previously specified by a targeting user. Alternatively, or in addition, the targeting user can receive notification that the targeted user has signed on and/or that the instant message has been sent. Instead of, or in addition to, automatically sending an instant message and/or notifying the targeting user, a predefined operation specified by the targeting user (e.g., operating system command, script or executable file) can be performed. These various operations can be performed on one or more client systems, on one or more server systems, or any combination thereof.

Abstract: Compressing the digitized time-domain continuous input signal typically includes formatting the input signal into a plurality of time-domain blocks having boundaries, forming an overlapping time-domain block by prepending a fraction of a previous time-domain block to a current time-domain block, transforming each overlapping time-domain block to a transform domain block including a plurality of coefficients, partitioning the coefficients of each transform domain block into signal coefficients and residue coefficients, quantizing the signal coefficients for each transformed domain block and generating signal quantization indices indicative of such quantization, modeling the residue coefficients for each transform domain block as stochastic noise and generating residue quantization indices indicative of such quantization, and formatting the signal quantization indices and the residue quantization indices for each transform domain block as an output bit-stream. The continuous data may include audio data.

Abstract: Enabling low-latency reduction of quantization-induced block-discontinuities of continuous data formatted into a plurality of data blocks having boundaries typically includes forming an overlapping input data block by prepending a fraction of a previous input data block to a current input data block, identifying regions near the boundary of each overlapping input data block, and excluding regions near the boundary of each overlapping input data block and reconstructing an initial output data block from the remaining data of such overlapping input data block. The continuous data may include audio data and/or time-domain data. The low-latency reduction of quantization-induced block-discontinuities of continuous data may be applied to at least one of a coder and decoder.
