International Classification:

G06F 1300

US Classification:

345537, 345548, 345603

Abstract:

A method and apparatus for display of graphical data is described. The invention provides an architecture for graphics processing. The architecture includes pipelined processing and support for multi-regional graphics. In one embodiment, a graphics driver according to the invention can receive multiple independent streams of graphical data that can be in different graphical formats. The independent streams are synchronized and converted to a common format prior to being processed. In one embodiment, multi-regional graphics are supported with off-screen and on-screen memory regions for processing. The regions of the multi-regional graphic are rendered in an off-screen memory. The data in the off-screen memory are converted to a common format and copied to on-screen memory. The data in the on-screen memory is used to generate an output image. Alpha blending can also be programmed to provide multi-regional graphics or other graphical features.

International Classification:

G06F 1/00

US Classification:

713500, 713501, 375371, 375354

Abstract:

A method and apparatus for receiving clocked data signals such as SPI-4. 2 data signals is described. In one embodiment, each data signal lane is deskewed with respect to the clock by oversampling the signal on that lane, and considering multiple versions of a data sequence at different temporal offsets to the clock for correct reception of a training sequence. One of the temporal offsets is subsequently selected to provide the received bit sequence for that lane. Other embodiments are described and claimed.

US Classification:

709206, 726 7

Abstract:

Messages exchanged among users of a relationship management and work collaboration system are organized within user-defined, secure communication channels organized according to user-defined hierarchies that represent the users' personal relationships with one another. Security of the communications channels is maintained using individual, dynamic keys, each of the keys being uniquely associated with a respective one of the channels, and being generated according to combinations of individual passwords established by each respective channel's participants. In-bound messages in the form of e-mails are received and associated with respective ones of the channels according to e-mail aliases associated with the inbound messages. Out-bound e-mails may be sent to channel participants according to e-mail addresses associated with the participants and channel preferences established by the system users. In some instances, messages are posted or not posted to those of the channels under the control of respective moderators and channel participants.

G06F 1516

US Classification:

713201

Abstract:

Authentication methods, systems and computer program products ensure that user media streaming requests originate with web documents having an authorized URL. The user makes a streaming request to a media server with a URL including a URL prefix, a path, and the name of a media work to be performed, which URL the media server compares with earlier made URL entries in a pre-established database. If there is a URL correspondence between a URL in the pre-established database and the URL extracted from the HTML document received by the browser from a web server, then streaming of the particular work is authorized.

US Classification:

707512

Abstract:

The production of synchronization scripts and associated annotated multimedia streams for servers and client computers coupled to each other by a diverse computer network which includes local area networks (LANs) and/or wide area networks (WANs) such as the intermet. Annotated multimedia streams can include a compressed video stream for display in a video window, an accompanying compressed audio stream and annotations. Synchronization scripts include annotation streams for synchronizing the display of video streams with annotations, e. g. , displayable events, such textual/graphical data in the form of HTML pages with Java applets to be displayed in one or more event windows. The producer includes a capture module and an author module for capturing video streams and generating annotation streams, respectively. The capture module compresses the video stream using a suitable compression format. Annotation streams include annotation frames which provide either pointer(s) to the event(s) of interest or include displayable data embedded within the annotation stream.

International Classification:

H04B 100

US Classification:

381119

Abstract:

A multimedia controller apparatus provides for computer programmed volume control and summing of audio signals in an enhanced multimedia environment. The apparatus is capable of receiving and processing inputs from a CD-ROM FM synthesizer, general MIDI audio, microphone, PCM sampled sound, and telephony systems. From these inputs, it produces outputs for PCM sampled sound, telephony systems, and stereo line-out. Additionally, it provides for the integration of telephonic support functions into a multimedia system. The multimedia controller apparatus comprises a volume control portion for receiving and controlling the volume of a plurality of analog input signals. The volume controlled input signals are then combined by an aggregation portion. A telephony processing portion is also provided for processing the telephony input signals. Stereo outputs, mono outputs, digital samplable outputs, and telephony outputs can be formed from the combined analog and telephony signals by an output portion.

US Classification:

709219

Abstract:

Client computer(s) retrieve and display synchronized annotated multimedia streams from servers dispersed over a diverse computer network which includes local area networks (LANs) and/or wide area networks (WANs) such as the internet. Multimedia streams provided to the client computer(s) can include a compressed video stream for display in a video window and an accompanying compressed audio stream. Annotations, i. e. , displayable events, include textual/graphical data in the form of HTML pages with Java applets to be displayed in one or more event windows. The video/audio and annotation streams are produced and then stored in stream server(s). Annotation streams include annotation frames which provide either pointer(s) to the event(s) of interest or include displayable data embedded within the annotation stream. Accordingly, each annotation frame includes either an event locator or an event data. In addition, each annotation frame includes an event time marker which corresponds to the time stamp(s) of associated video frame(s) within the video stream.
