摘要： A system for presenting a virtual advertisement or other virtual content in a sequences of frames of a video presentation utilizes data identifying a candidate region in the sequence of frames, a pixel signature for the region, the signature comprising a range of R, G, B values for pixels based on a standard deviation from an average value, and stored virtual content, such as an advertisement, to be implanted in the candidate region or regions. In operation, as frames having the candidate region are processed by an integration system, the alternative virtual content is substituted by default for the candidate region, except if a pixel value in the region falls outside the pixel signature range. The result is an ad that appears to be on a surface in the video presentation, as images that come between the ad and the viewer occlude the advertisement. Apparatus and methods for providing the video presentation and data sets for regions and advertisements are disclosed as well. Methods are provided for selecting candidate regions and for implanting virtual content in various embodiments.

摘要： An authoring system for interactive video has two or more authoring stations for providing authored metadata to be related to a main video data stream and a multiplexer for relating authored metadata from the authoring sources to the main video data stream. The authoring stations annotate created metadata with presentation time stamps (PTS) from the main video stream, and the multiplexer relates the metadata to the main video stream by the PTS signatures. In analog streams PTS may be created and integrated. In some embodiments there may be multiple and cascaded systems, and some sources may be stored sources. Various methods are disclosed for monitoring and compensating time differences among sources to ensure time coordination in end product. In different embodiments transport of metadata to an end user station is provided by Internet streaming, VBI insertion or by Internet downloading. User equipment is enhanced with hardware and software to coordinate and present authored material with the main data stream.
摘要翻译：用于交互式视频的创作系统具有两个或更多个创作站，用于提供与主要视频数据流相关的创作元数据，以及用于将来自创作源的创作元数据与主视频数据流相关联的多路复用器。创作站从主视频流注释具有演示时间戳（PTS）的创建的元数据，并且多路复用器通过PTS签名将元数据与主视频流相关联。在模拟流PTS可以被创建和集成。在一些实施例中，可以存在多个和级联系统，并且一些源可以是存储源。公开了各种方法来监测和补偿源之间的时间差，以确保最终产品的时间协调。在不同实施例中，元数据到最终用户站的传输是通过Internet流式传输，VBI插入或通过因特网下载来提供的。用户设备通过硬件和软件进行增强，以协调和呈现主要数据流的创作材料。
