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:
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.

Program code enabling the streaming of HD content in real-time to a game console is stored on a storage medium remote from the game console. The game console executes software that facilitates transfer of the program code from the remote storage medium to the game console. The program code ensures that sufficient bandwidth exists on a network between the game console and a HD tuner, and enables the streaming of HD content in real-time to the game console.

摘要:
A digital media system uses client buffer fullness reports to detect clock drift between a clock on a host/source device that delivers streaming media content and a clock on a client playback device that receives the streaming media content. The system provides a reduction in playback interruptions during playback of streaming media content and a greater potential that “live” content encoded by a host/source device can actually be experienced as “live” content through playback on a client device.
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:
While streaming media content, trick mode operation is optimized to a level that can be readily accommodated by available resources of a media delivery system. In one possible strategy, a trick mode optimization module may decrease the bit rate of the media content stream by progressively dropping delta frames and then a fraction of the remaining key frames as needed. According to another possible strategy, the trick mode optimization module may decrease the bit rate of the media content by progressively dropping sequences of frames between successive key frames. In addition, the trick mode optimization module may combine strategies and drop sequences between key frames, as well as dropping delta frames from the remaining sequences.
摘要:
Real-time streaming of media content from a server to a device and reduction of startup latencies during distribution are described. In one configuration, once a latency inducing event is initiated (i.e. a channel change, a stopping and starting of the streaming of live media content, or transrating to different streaming rates) a pre-roll process includes decreasing the frame rate of the media content being streamed to the monitor from an initial rate to a reduced rate. Simultaneously, a jitter buffer is flushed and rebuilt with media content samples arriving at a decoder at the initial rate, and being used for playback at the reduced rate.
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.
