    摘要: A live media stream encoding system encodes live media streams into numerous variants of the live media streams each including multiple fragments. Live media streams are delineated, dispatched as jobs, and converted using distributed and dynamically scalable encoder and fragmenter resources without using any centralized encoding management system. Encoded fragments are maintained in shared storage and accessed as needed by devices during playback. Localized redundancy and/or geographic redundancy is provided throughout the system to prevent disruption upon failure of a particular node.

    摘要: Live media streams are delineated for distributed encoding and fragmentation in a dynamically scalable distributed resource system. In some examples, live MPEG-2 media streams are separated into groups of pictures (GOPs) and converted into jobs for encoding and fragmentation systems. Multiple jobs may be created for the same live media stream to provide for different quality levels for each fragment of each channel. Shared resources such as a pool of dynamically scalable virtual machines can be used to process the individual jobs. Encoded fragments may be H.264 fragments maintained on shared storage. A particular live stream corresponding to a particular quality level can be reconstructed using the encoded fragments.

    摘要: Live media streams variants are encoded in real-time in a dynamically scalable distributed resource system. In some examples, each live MPEG-2 media stream is encoded into numerous variants to allow for playback on a variety of devices, networks, and players supporting different resolutions, audio bit rates, quality levels, and even codecs, etc. Live stream variant consumption is monitored and analyzed to dynamically allocate and deallocate resources to processing particular variants based on demand at particular times. Live stream variant consumption can also be predicted to preemptively allocate and deallocate resources.

    摘要: Live media streams are encoded and fragmented to generate encoded fragments appropriate for different devices and networks. Different encoded fragments may correspond to different resolutions, audio bit rates, quality levels, and even codecs, etc. Devices request encoded fragments as needed to reconstitute a live media stream for playback. In many instances, encoding and fragmentation jobs are provided to numerous distributed and scalable encoder and fragmenter systems. Encoding and fragmentation jobs are intelligently weighted and scheduled to prevent any disruption or delay in playback of any particular live stream.

    摘要: A technique for radio link detection in a wireless communication system includes estimating a first error rate of an indicator channel. In this case, the indicator channel includes an indication of a number of symbols in a control channel. A second error rate of the control channel is also estimated. The first and second error rates are then combined to provide a performance metric. Based on the performance metric, a determination is made as to whether a radio link problem exists.

    摘要: Systems and methods for multi-object reporting in a content management system. A report type definition may define which objects are involved and how they are related. A report execution engine may generate a multi-object query language statement to translate the report type definition into query language. A query language execution engine may break the query language statement down into separate single pieces. A cost optimization engine may determine if it is cost efficient to join the objects. An indexed access execution engine may extract unique IDs of the objects and join the unique IDs to generate an index. A Lucene based search engine may be accessed according to the index, and the response is post processed to generate a multi-object report.
