Video Format for Digital Video Recorder
First Claim
1. A method for defining a plurality of video formats for a video recording device, the method comprising:
- specifying a plurality of parameters for a first video format that encodes video clips at least partially in an interframe format;
specifying a plurality of parameters for a second video format that encodes video clips in an intraframe only format; and
specifying that each of a plurality of video images encoded using the second video format is encoded as a plurality of slices, the plurality of slices of a particular video image for decoding by a plurality of processing units of a video decoding device.

Abstract
Some embodiments provide a video recording device for capturing a video clip. The video recording device receives a selection of a non-temporally compressed encoding scheme from several different encoding schemes for encoding the video clip. The different encoding schemes include at least one temporally compressed encoding scheme and at least the selected non-temporally compressed encoding scheme. The video recording device captures the video clip as several frames. The video recording device non-temporally encodes each of the frames as several slices. The slices of a particular frame are for decoding by several processing units of a video decoding device. The video recording device stores the video clip in a storage.

16. A computer readable medium of a video recording device, the computer readable medium storing a computer program which when executed by at least one processor of the video recording device captures a video clip, the computer program comprising sets of instructions for:
-
receiving a video clip captured by the video recording device as a set of video images, each video image having a particular width; reducing the width of the video images; encoding each of the reduced-width video images without reference to any other video image; and storing the video images in a storage of the video recording device. - View Dependent Claims (17, 18, 19, 20, 21)
