Abstract

A method of recording a video by parsing a video stream in units of Group of Pictures (GOP), and a video apparatus incorporating the same are provided. The video recording method includes generating a predetermined number of Group of Pictures (GOP) into a single file, and storing the generated file, and storing the name of the file. Accordingly, use of storage space due to index file is avoided, and failure of high-speed playback due to a damaged index file is prevented.

Description

technical field [0001] Methods and devices consistent with the present invention relate to recording video. More specifically, methods and apparatuses consistent with the present invention relate to recording video by analyzing a video stream in units of Group of Pictures (GOPs), and replaying the video stream written in units of GOPs. Background technique [0002] The video device operates to record an externally received video stream and to replay the recorded video stream. [0003] A video stream includes a number of groups of pictures (GOPs). In other words, a video stream includes multiple pictures. [0004] To record a video stream, a video device generates the video stream into a single video file and writes to the generated video file. In addition, the video device independently generates and writes an index file indicating where the screens of the video stream are located. [0005] The index file is used as a reference when playing back the recorded video stream...
