    • 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.
    • 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。 在段的终点之前增加数据速率,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。

    • A system and method for presenting and displaying video asset information to a viewer to assist the view in selecting a video asset for viewing. The video assets can be available from a plurality of different video asset sources, such as VOD (video on demand), PVR (personal video recorders) and broadcast (including over the air, cable, and satellite). Images from the video assets are displayed in a uniform manner, along with information about the video assets. The information includes data in a metadata category. The view can select one of the video assets for viewing, but also can navigate using metadata categories such as genre, actors, director etc. This allows a much easier and natural navigating and selection process for viewers.
    • 一种用于向观众呈现和显示视频资产信息以辅助视图选择用于观看的视频资产的系统和方法。 视频资产可以从多个不同的视频资源来获得,例如VOD(视频点播),PVR(个人录像机)和广播(包括空中,电缆和卫星)。 来自视频资产的图像以统一的方式显示,以及关于视频资产的信息。 信息包括元数据类别中的数据。 该视图可以选择其中一个视频资源进行查看,也可以使用元数据类别(如流派,演员,导演等)进行导航。这样可以让观众更容易自然的浏览和选择过程。
