    摘要： A method of preparing data streams to facilitate seamless switching between such streams by a switching device to produce an output data stream without any switching artifacts. Bi-directional switching between any plurality of data streams is supported. The data streams are divided into segments, wherein the segments include synchronized starting points and end points. The data rate is increased before an end point of a segment, to create switch gaps between the segments. Increasing the data rate can include increasing a bandwidth of the plurality of data streams, for example by multiplexing, or compressing the data.The present invention can be used, for example, with MPEG or AC-3 encoded audio and MPEG encoded video segments that are multiplexed into MPEG-2 transport streams.Also included are specific methods for preparing MPEG video streams and multiplexing MPEG video with MPEG or AC-3 audio streams to allow a receiver to create seamless transitions between individually encoded segments.

    摘要翻译： 一种准备数据流以促进切换装置在这种流之间无缝切换以产生输出数据流而不产生任何切换伪影的方法。 支持任意多个数据流之间的双向切换。 数据流被分成段，其中段包括同步的起点和终点。 数据速率在段的终点之前增加，以在段之间创建交换机间隙。 增加数据速率可以包括例如通过复用或压缩数据来增加多个数据流的带宽。 本发明可以用于例如MPEG-3编码的MPEG-2编码视频片段，其被复用到MPEG-2传输流中。 还包括用于准备MPEG视频流和用MPEG或AC-3音频流复用MPEG视频的特定方法，以允许接收机在单独编码的段之间创建无缝转换。

    摘要： Systems and methods for push-based dynamic bandwidth allocation deliver addressable, advertising content in a digital network. Bandwidth is allocated on a push basis in response to receiving a trigger from a content distribution stream. The trigger contains data indicating an addressable break. A portion of bandwidth is then allocated to an addressable content stream based on the data of the trigger. The addressable content stream is then streamed to a receiver during the addressable break and the receiver is tuned from the broadcast stream to the addressable content stream for the duration of the addressable break. The additional bandwidth is de-allocated at the end of the addressable break.

    摘要： Systems and methods for push-based dynamic bandwidth allocation deliver addressable, advertising content in a digital network. Bandwidth is allocated on a push basis in response to receiving a cue tone from a broadcast stream. The cue tone contains data indicating an addressable break. A portion of bandwidth is then allocated to an addressable content stream based on the data of the cue tone. The addressable content stream is then streamed to a receiver during the addressable break and the receiver is tuned from the broadcast stream to the addressable content stream for the duration of the addressable break. The additional bandwidth is de-allocated at the end of the addressable break.
