  • Publication number: 20030188152
    Abstract: A system, method and computer readable medium for providing secure IP-based streaming in a format independent manner is disclosed. The method on a content mastering system begins with an encoded media file consisting of content data and associated metadata. First, the metadata is read from the encoded media file. Next, the encoded media file including the content data and the associated metadata is encrypted. Then, in a streaming server system, the encoded/encrypted media file is divided into more than one data packet, streamed in accordance with one or more parameters in the metadata. Each data packet includes a portion of the encoded/encrypted media file and an offset value corresponding to a location within the encoded/encrypted media file. The data packets are then streamed to a client information processing system (i.e., the client) over a network.

  • Publication number: 20030002854
    Abstract: Systems, methods, and computer products that facilitate transmission of information used for fast and responsive video and audio playback at non-standard, trick mode speeds. An embodiment of the present invention uses low resolution, compressed, and independent frames derived from the encoded digital video or audio information to facilitate the operation of user-requested VTR-like speed change functions associated with digital video and digital audio frames. The present invention greatly simplifies locating specific frames in a video or audio presentation for purposes such as fast forward and fast reverse scanning that is typically used in digital editing.

  • Publication number: 20020184488
    Abstract: A system, method, and computer product that accelerates encryption and decryption of data while using both a static key and a dynamic key. The present invention eliminates intermediate decryption of data that is transmitted between computer systems. More particularly, encryption efficiency is improved by eliminating decryption of the statically encrypted data while incorporating the advantages of a dynamic key such as enabling rapid change of the dynamic key. The efficiency improvements reduce the computer resources required to protect the data and therefore stronger data encryption may be enabled with the saved computer resources. End-to-end security of the data is maintained without the need for trusted data servers.

  • Patent number: 5959180
    Abstract: DNA sequences from potato which encode the enzyme solanidine UDP-glucose glucosyltransferase (SGT) are disclosed. Recombinant DNA molecules containing the sequences, and use thereof, in particular, use of an antisense DNA construct to inhibit the production of SGT and thereby reduce glycoalkaloid levels in solanaceous plants, e.g., potato, are described.

  • Patent number: 5603058
    Abstract: A media streamer (10) includes at least one control node (18); at least one storage node (16, 17) for storing a digital representation of a video presentation; and a plurality of communication nodes (14) each having an input port that is switchably coupled under the direction of the control node to an output of the at least one storage node for receiving a digital representation of a video presentation therefrom. Each of the plurality of communication nodes further includes at least one output port for coupling to a first end of a communications bus (210). Individual ones of the communication nodes output a digital representation of a video presentation as a sequence of data bursts to the first end of the communications bus. The media streamer further includes an adapter (15), coupled to a second end of the communications bus, for receiving the sequence of data bursts and for converting the received sequence of data bursts to a substantially isochronous data stream that represents a video presentation.

  • Patent number: 5586264
    Abstract: A data storage system includes a mass storage unit storing a data entity, such as a digital representation of a video presentation, that is partitioned into a plurality N of temporally-ordered segments. A data buffer is bidirectionally coupled to the mass storage unit for storing up to M of the temporally-ordered segments, wherein M is less than N. The data buffer has an output for outputting stored ones of the temporally-ordered segments. The data storage system further includes a data buffer manager for scheduling transfers of individual ones of the temporally-ordered segments between the mass storage unit and the data buffer. The data buffer manager schedules the transfers in accordance with at least a predicted time that an individual one of the temporally-ordered segments will be required to be output from the data buffer.
