Streaming Filesystem & Multimeda Filesystem

본 조사는 PVR같은 Multimedia embedded set-top box에 넣을만한
멀티미디어 재생을 위한 파일시스템을 찾아본 조사이다.

실예: PVR 시스템
-------------------------------------------
PVR 묶음

MythTV
리눅스 기반의 PVR set-top box기 때문에 리눅스에서 동작되는
그나마 나은 저널링 파일  시스템을 추천하는 것이지 JFS가
MMFS는 아니다.
http://www.mythtv.org/docs/mythtv-HOWTO-3.html
- JFS가 가장 알맞다.
http://www.mythtv.info/wiki/index.php/File_storage
- JFS나 XFS가 좋다.

Issue
---------------------------------------------

1. Real-Time Disk Scheduling
File system node assigns deadlines to real-time I/O based on stream data rate.
Disk I/O is ordered by deadline.
Quota of disk bandwidth reserved for non-realtime I/O.
Non-realtime I/O is interleaved with real-time according to quota.
