Embodiment Construction

[0026] The present principles relate to managing time-shifted data.

[0027] While those skilled in the art will readily conceive of various applications in which the present principles may be applied, the following description will focus on an embodiment of the present principles applied to a set top box having digital video recorder functionality and time shifting functionality. However, given the teaching of the present principles provided herein, those skilled in the art will readily conceive of other devices and applications in which the present principles can be applied while maintaining the spirit of the present principles. For example, the present principles can be incorporated into any device that has multimedia playback capabilities as well as recording and time-shifting capabilities. Thus, the present principles can be incorporated into digital video recorder (DVR) capable set-top boxes, stand-alone DVRs, home media servers, computer media stations, tablet computer ...

Abstract

There are provided respective systems and methods for recording and playing back media content. The system for recording media content includes a segmenter (303) for splitting transport stream data and index data corresponding to the media content into discrete files at periodic intervals on access point boundaries. Each of the discrete files includes a respective transport segment and a respective index segment. The system also includes a segment storage device (304) for storing the discrete files.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 584,351, filed January 9, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] The present principles relate generally to time-shifting functionality, and more specifically to managing time-shifted data. Background technique [0004] The core function of a digital video recorder (DVR) is to record and playback broadcast multimedia content, such as video content (and any audio content corresponding to it, but for the sake of brevity, hereinafter collectively referred to as "video content"). Many DVRs allow time shifting functionality. The time-shift feature is essentially a scrolling buffer of live broadcast content. This allows trick-mode operations such as pausing, rewinding, and fast-forwarding to be used with live broadcast content. A typical time-shifting implementation will maintain a buffer of the last...
