    摘要： In one example, multimedia content is requested from a plurality of storage modules. Each storage module retrieves the requested parts, which are typically stored on a plurality of storage devices at each storage module. Each storage module determines independently when to retrieve the requested parts of the data file from storage and transmits those parts from storage to a data queue. Based on a capacity of a delivery module and/or the data rate associated with the request, each storage module transmits the parts of the data file to the delivery module. The delivery module generates a sequenced data segment from the parts of the data file received from the plurality of storage modules and transmits the sequenced data segment to the requester.

    摘要： A construction arrangement for a small set-top box to protect cryptographic capabilities and prevent a digital program in clear from being able to be tapped as required by Digital Rights Management protocols. A first layer of sheet metal capable of blocking X-rays, is formed as a shallow pan to hold a set of printed circuit boards. A second layer has a thin epoxy based printed circuit material. A third layer has a printed circuit board with integrated components placed on top of the second layer. A fourth layer has a three layer thin printed circuit board with a first and second metallic layer and holes for large components, such as electrolytic capacitors. A black liquid thermosetting epoxy fills the interstices between the sheet metal layer and the second layer, and between the second layer and the third layer, and between the third layer and the fourth layer, thereby preventing access to exposed circuit trace carrying digital signals in the clear. A connection from the first metallic layer of the fourth printed circuit material layer to a sending circuit and a connection from the second metallic layer so that a short between these two layers sets off an indicator circuit that an attempt is made to enter the protected area.

    摘要： A first frame deadline is calculated and attached to an I/O request for prioritizing and retrieving video data frames from a shared disk cluster. Disk adapters queue video data frame requests according to the deadline incorporated in the frame requests. Data frames are transmitted to a requesting end user utilizing the attached deadline time to schedule the frames according to a time priority. Alternatively, a “slack” time is computed and utilized to determine when the first frame and subsequent frames of the requested video data may be retrieved from disk and present in the video server's memory in order to avoid a visible delay in sending that frame to the end user.

    摘要： A method of broadcasting a plurality of media to an unlimited number of subscribers through a digital communications network having a limited bandwidth is disclosed. The method selects a first group of digitized media each divided into a plurality of temporally related frames. The method transmits the plurality of temporally related frames of the first group of digitized media through the digital communications network in a compressed format, wherein the transmission includes a header along with each of the plurality of temporally related frames wherein the header identifies the temporal sequence of the frames. The method retransmits the plurality of temporally related frames of the first group of digitized media through the digital communications network in the compressed format immediately upon completion of the step of transmitting the plurality of temporally related frames of the first group of digitized media.

    摘要： In a video server, multimedia data for a production is archived with data blocks for a video disk file and data blocks for audio disk files and data blocks for auxiliary disk files all intermixed together in a single tape file, in approximately the same order required for producing a multimedia data stream. During restoring of the production, as the disk files are being copied to disk storage systems from the tape file, the data may be retrieved from the same disk files and played as a multimedia data stream as soon as enough information is available in the files to form the stream. Disk files are striped across a multitude of disk files systems, by a commutator and a multitude of input/output units share access to all the files in all the disk file systems, for example, using a periodically switching round robin scheme or more complex scheduling. Also, during restoration, the same input/output unit of the server that is copying the data from the tape file to the disk drive may be is used to play a multimedia data stream for the production and simultaneously other input/output units of the server are able to play multimedia data streams for the same production from those portions of the disk files for the production that have already been restored.

    摘要： When data including video and/or audio data is dispersed into data each having a predetermined unit and recorded in a non-linear accessible recording medium, or reproducing data dispersed and recorded, in case that the status information is not output in a predetermined period, it is decided that an error occurred to perform an error processing. Also, when data including video and/or audio data is dispersed into data each having a predetermined unit and recorded in a non-linear accessible recording medium with a redundancy, in case that an error occurred, which can be corrected within the redundancy, the fault information is recorded and the data is restored immediately by using the redundancy when the data of which an error occurred is reproduced based on the fault information.
