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 (12) to prepare a plurality of zoom location indicators (20) including an element indicative of at least one horizontal position and al least one vertical position in the video frames (18), and a stream processor to temporally synchronize the zoom location indicators (20) and the video frames in the digital video stream, such as the video frames are available to be zoomed by die content consumer system based on the zoom location indicators during playback of the digital video stream.
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数字视频流的系统，用于准备多个变焦位置指示器的变焦位置处理器（12） 20），包括指示视频帧（18）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（20）和视频帧，诸如在数字视频流播放期间，基于缩放位置指示符，视频帧可用于由内容消费者系统缩放。

摘要： A viewing estimation system includes: a receive module for a time period measurement of how long a media content item 52 was rendered by an end-user rendering unit (e.g. set top box (STB) 12, Figure 1) and actually outputted for display to an audiovisual (AV) outputting arrangement (e.g. television 16, Figure 1) during a time window 50; an activity determination module to determine user interaction (e.g. via a remote control) with the rendering unit (STB) and/or the AV device; and a module to estimate viewing by the user of content item such that, if user interaction was not determined during the time window (absence or lack of viewer interaction response in window 50, e.g. channel change 54 before window 50, and viewer or user presence uncertain), then time attributed to the viewing of the content is reduced to less than the time measured for content rendering and display; this may be the minimum of: a capping limit; a time measurement based on content render time; or the average content duration. A broadly equivalent method is also independently claimed.
