摘要： A congestion controller for a media server monitors both the buffer status of the client device as well as the network performance. The congestion controller may increase or decrease the pacing of packets transmitted over the network based on the fullness of a buffer on the client device, but may also change the bit rate of the packets based on the network performance. By monitoring both the client device status and network performance, the pacing and bit rate of the packets may be varied together to achieve an optimized throughput and maximized user experience of the media.

摘要： A media experience policy engine includes three components: an information manager, a policy evaluator, and an enforcement module. The information manager collects information regarding the current state of a media delivery system, such as, for example, usage of a CPU, memory, hard disk, (I/O) interface, and a network. This collected data is then verified by the policy evaluator to see if resource contention is, or is close to, occurring. If so, existing or potential conflicts are dealt with by the enforcement module, which applies corrections, such as, for example, limiting the access of later chronologic users, or degrading the user experience of all users, in accordance with a desired policy in order to vitiate the resource contention and maintain a user experience consistent with the desired policy.

摘要： Partial content syncing in a network media receiver is disclosed. One embodiment comprises identifying available cache space on the media receiver, detecting a media data file to be downloaded from a media server, and pre-buffering a portion of the media data on the media receiver prior to selection of the media data file for playback. In this manner, substantially glitch-free playback of a media data file may be started with little delay and with relatively little local storage.

摘要： An intelligent retransmission of data stream segments is disclosed. One embodiment comprises detecting a missing media data segment at a media receiver, assigning a value to the missing media data segment based upon media playback consequences of not utilizing the missing media data segment, comparing the value with a threshold, and requesting retransmission of the missing media data segment from a media server if the value meets a predetermined condition relative to the threshold. In this manner, retransmission is requested when it is determined that retransmission will improve playback performance relative to non-retransmission.

摘要： An intelligent multi-sending of data stream segments is disclosed. One embodiment comprises monitoring one or more variable data transmission parameters, detecting one or more invariant media data segment parameters, assigning a value to the media data segment based upon the one or more invariant media data segment parameters and the one or more variable data transmission parameters, comparing the value to a threshold, and sending multiple copies of the media data segment over a network link to a media receiver if the value is above the threshold.

摘要： A home entertainment network transmits audio/video decrypted from a DVD over a network to a media receiver using a secure channel. The A/V data is re-encrypted in a second encryption format amenable to transmission over the network. The media stream is thereby compliant with copy protection and digital rights management requirements. The media server constructs an emulated user interface corresponding to an actual instantiation of a navigation menu on the media server to solicit user input at the media receiver. The media server alternatively constructs a unique identifier of the DVD based upon the file structure on the DVD to search for menu navigation commands over an external network for heuristic navigation control.

摘要： A media server in a home entertainment network coordinates with a media receiver connected with the network to provide a media representation with a combined user interface on an attached display device. The media server receives compositing information from the media receiver over the network regarding the placemement of UI components generated by the media receiver. In response, the media server may adjust the positioning of graphics, media control information, metadata, media presentation windows, and other UI components for presentation by the media receiver such that the UI components generated by the media server do not interfere with the UI generated by the media receiver when rendered to the display device. Alternately, the media receiver may adjust the position of UI components such that the UI components generated by the media receiver do not interfere with the UI generated by the media server upon presentation.

摘要： Transrate/transcode functionality of media processing units in devices distributed within a networked media system are harnessed to enable media streaming to devices across networks while overcoming insufficient bandwidth to transmit the source content or while providing reformatted media to devices that do not support the source format. A policy engine may reallocate media processing resources for greater efficiency. The policy engine may further schedule time-slicing of media segments in available hardware and software-based codecs. Time-slicing may be used to transformatively process one or more media streams across potentially multiple media processing units connected within a network. The media streams are divided into independently processable segments based upon knowledge of underlying media formats. Processing requirements and a priority processing order may be determined for and assigned to each independently processable segment. The segments may be scheduled for delivery to the media processing units based upon the assigned priority and processing requirements.
