摘要： A Web-based video-editing system (10) using a high-performance multimedia software library (34) having a toolkit, the toolkit being a set of reusable, high-performance primitives and abstractions that are at an intermediate lev el of abstraction between C and conventional libraries. By decomposing common multimedia data types and operations into thin abstractions and primitives, programs written using the toolkit achieve performance competitive with hand - tuned C code, but which are shorter and more reusable. The toolkit programs can employ optimizations that are difficult to exploit in C and are impossib le to use in conventional libraries.

摘要： A multimedia communications and computer platform that can serve as a network interface card combined with an internal distribution network for a full range of user terminal devices. It includes an interconnection network module that serves to route all incoming and outgoing information by way of high speed buses with value added features for communication protocol acceleration. In particular, attached to the different ports of the network are an ATM module, a communications processor, a media processor and a variety of terminal devices. By migrating processing intensive functions of network protocol termination, media stream distribution and media stream adaptation into the network interface card, there are avoided the bottlenecks of the traditional CPU centric approach to ATM systems.

摘要： A method for presenting video on a local monitor and a remote monitor includes encoding an original video signal to produce a first compressed video signal. Using the first compressed video signal, the video signal is also encoded to produce a second compressed video signal. Both the first and second compressed video signals are transmitted to a local terminal at which the first and second compressed video signals are decoded to produce first and second decoded video signals. A first decoded version of the video signal is produced from a combination of the first and second decoded video signals. Only the first compressed video signal is transmitted to a remote terminal at which a second decoded version of the video signal is recovered from only the first compressed video signal. The first compressed video signal may be produced by motion compensation temporally encoding and spatially encoding the original video signal. The second compressed video signal may be produced by both spatially and motion compensation temporally decoding the first compressed video signal and subtracting each pixel of each picture thereof from a corresponding, spatially and temporally aligned pixel of a picture of the original video signal to form a difference video signal. The difference video signal is then only spatially encoded to produce the second compressed video signal. To produce the first decoded version of the original video signal, the first compressed video signal may be both spatially and motion compensation temporally decoded and the second decoded video signal may be only spatially decoded. Each pixel of each picture of the second decoded video signal may be added to a corresponding temporally and spatially aligned picture pixel of the first decoded video signal.

摘要： Methods and apparatuses for processing media data for transmission in a data communication medium. A set of data indicates how to transmit a time related sequence of media data according to a transmission protocol. The set of data, includes a time related sequence of data which is associated with the time related sequence of media data. The set of data may be utilized by a digital processing system to transmit the time related sequence of media data (e.g., by packets generated according to the transmission protocol and the set of data).

摘要： The present invention relates to information which allows transmission of time related data over a data communication medium. In one embodiment, a set of data includes at least one instruction to cause a digital processing system to generate a set of packets representing a time related sequence of media data. The set of packets is associated with a transmission protocol. The set of data includes a time related sequence of data which is associated with the time related sequence of media data.
