    摘要： Systems, devices and methods for managing and adjusting adaptive streaming traffic to optimize fairness are disclosed herein. In one embodiment, a method comprises: receiving a request for a media segment; locating the media segment; determining the bitrate of the requested media segment; and assigning priority information to the media segment, wherein a media segment having a lowest guaranteed bitrate is assigned a higher priority than media segments having higher bitrates.

    摘要： A direct memory-to-memory to streaming protocol driver for a media content playback system is provided. In one embodiment, the direct memory-to-memory to streaming protocol driver is a Remote Direct Memory Access (RDMA). In general, the RDMA to streaming protocol driver utilizes an RDMA-enabled network interface to obtain media content from a remote content distribution server. In order to emulate a streaming protocol layer of a network stack such as, for example, the User Datagram Protocol (UDP), the RDMA to streaming protocol driver encapsulates the media content according to the streaming protocol to provide streaming media content. The streaming media content is then provided to an associated streaming protocol-based playback function.

    摘要： Enhancing performance in a multicasting system comprising monitoring filtering costs in a multicasting system as system characteristics change over time, wherein the multicasting system is operating based on a first mapping, between a plurality of data flows and multicasting groups, to disseminate data to users that subscribe to one or more of the data flows; computing a second mapping in response to determining that overhead associated with filtering of unwanted flows at the user level has exceeded a threshold; and transitioning the multicasting system from using the first mapping to using the second mapping, in response to determining that the second mapping is feasible as applicable to one or more constraints associated with the multicasting system.

    摘要： Disclosed are video conferencing systems, devices, architectures, and methods for transcoding, transrating, and the like, to facilitate video streaming in a distributed arrangement. An exemplary translator in accordance with embodiments can include: an input configured to receive a first video stream in a first format, the first video stream being from a first media switch, the first media switch being associated with a first stream group having one or more first endpoints; and an output configured to provide a second video stream in a second format, the second video stream being sent to a second media switch, the second media switch being associated with a second stream group having one or more second endpoints, whereby the translator is configured to convert from the first to the second format. Further, the translator can be configured as a logical endpoint where a first interface having an input/output pair uses the first format and a second interface having another input/output pair uses the second format. The two formats may differ in at least one characteristic.

    摘要： Systems and methods are provided that combine Open Mobile Alliance Mobile Broadcast Services (OMA BCAST) with different bearers, such as China Multimedia Mobile Broadcasting (CMMB) by associating service-related identifiers within an OMA BCAST Electronic Service Guide (ESG) with CMMB bearer-specific parameters. Furthermore, associating IP source and/or destination address pairs of a service with the location of the service within the CMMB bearer can be achieved and used with unicast, multicast, and broadcast environments. Further still, systems and methods are provided that allow for ESG bootstrapping, where a desired electronic service guide can be discovered by bootstrapping, e.g., OMA BCAST ESG.
