摘要： A method for switching from playing a first compressed data segment to playing a second compressed recorded data segment, the method including playing an uncompressed copy of a start of the second compressed recorded data segment upon switching from playing the first compressed data segment, decoding the second compressed recorded data segment from a preceding random access point, the preceding random access point preceding, in the second compressed recorded data segment, a point at which playing is to be switched to the second compressed recorded data segment, stopping the decoding of the second compressed recorded data segment when reaching a point beyond a point currently being played in the uncompressed copy, and switching to playing the second compressed recorded data segment when playing the uncompressed copy of a start of the second compressed recorded data segment reaches the point at which the decoding of the second compressed recorded data segment was stopped. Related apparatus and methods are also provided.

摘要： A system for preparing a digital video stream for zooming by a content consumer system, including a video frame processor to prepare a plurality of video frames of the digital video stream, a zoom location processor to prepare a plurality of zoom location indicators in the digital video stream, each of the zoom location indicators including an element indicative of a least one horizontal position and at least one vertical position in the video frames, and a stream processor to temporally synchronize the zoom location indicators and the video frames in the digital video stream, such that the video frames are available to be zoomed by the content consumer system based on the zoom location indicators during playback of the digital video stream. Related apparatus and methods are also described.
摘要翻译：一种用于由内容消费者系统（包括视频帧处理器）进行缩放以准备数字视频流的多个视频帧的缩放的系统，用于在数字视频中准备多个缩放位置指示符的变焦位置处理器流，每个缩放位置指示符包括指示视频帧中的至少一个水平位置和至少一个垂直位置的元素;以及流处理器，用于在数字视频流中时间上同步变焦位置指示符和视频帧，使得在数字视频流的回放期间，基于缩放位置指示符，视频帧可被内容消费者系统缩放。还描述了相关装置和方法。

摘要： A content viewing estimation system including a module to receive a time measurement of how long at least part of a content item was rendered by an end-user rendering unit and outputted for display to an audio-visual outputting arrangement during a time window, a module to determine user interaction with the end-user rendering unit and/or the audio-visual outputting arrangement, a module to calculate an average content item duration of a plurality of content items rendered by the end-user rendering unit during the time window, and a module to estimate viewing by the user of the at least part content item such that if user interaction was not determined during the time window then time attributed to the viewing of the at least part content item is set to the minimum of a capping limit, the time measurement, and the average content item duration. Related apparatus and methods are also described.
摘要翻译：一种内容观看估计系统，包括：模块，用于接收由终端用户呈现单元呈现内容项目的至少部分多久的时间测量值，并在时间窗口内输出以供视听输出装置显示;模块确定与终端用户呈现单元和/或视听输出装置的用户交互;模块，用于计算在时间窗口期间终端用户渲染单元呈现的多个内容项的平均内容项持续时间;以及用于估计用户对所述至少部分内容项目的观看的模块，使得如果在所述时间窗口期间未确定用户交互，则归因于所述至少部分内容项目的观看的时间被设置为限制上限的最小值，时间测量和平均内容项持续时间。还描述了相关装置和方法。
