    Abstract: A compressed digital audio signal is transmitted from an audio source along a connection wire to an audio receiver. The digital audio signal can encode digital audio data having different sampling frequencies, frames sizes, and other information. The audio receiver that receives the digital audio signal can decode and convert the compressed digital audio signal into multiple synchronized analog signals, which are used to drive multiple speakers. The audio receiver may also synchronize the audio data with associated video data so that the audio playback and video playback are “in sync”, despite delay introduced by the audio signal decoding at the audio receiver.

    Abstract: An adaptive stream player that has control over whether a retrieved stream is cached in a local stream cache. For at least some of the stream portions requested by the player, before going out over the network, a cache control component first determines whether or not an acceptable version of the stream portion is present in a stream cache. If there is an acceptable version in the stream cache, that version is provided rather than having to request the stream portion of the network. For stream portions received over the network, the cache control component decides whether or not to cache that stream portion. Thus, the cache control component allows the adaptive stream player to work in offline scenarios and also allows the adaptive stream player to have rewind, pause, and other controls that use cached content.

    Abstract translation: 控制是否将检索到的流缓存在本地流缓存中的自适应流播放器。 对于播放器请求的至少一些流部分,在通过网络出去之前,高速缓存控制组件首先确定流高速缓存中是否存在流部分的可接受版本。 如果流缓存中有可接受的版本,则提供该版本,而不必要求网络的流部分。 对于通过网络接收的流部分,高速缓存控制组件决定是否高速缓存该流部分。 因此,高速缓存控制组件允许自适应流播放器在脱机情况下工作,并且还允许自适应流播放器具有使用缓存内容的倒带,暂停和其他控制。

    Abstract: An acoustic resonator (20) has a resonator cavity (22) with a resonator port (24) for communicating with an exhaust flow passage (26) conducting acoustic waves therethrough. Adjustable port structure varies acoustic impedance of the port by various combinations including translation to vary area along an arcuate surface, translation between discrete areas, translation to cumulatively open port area, multiple translation, multiple ports, rotational area change, and rotational length change. Adaptive control may be provided. A combined passive and active acoustic system may also be provided.
