DESIGN TRADE-OFFS FOR REAL-TIME CHAPTER 10 REPRODUCTION

Abstract

This paper presents an analysis of various methods to address the reproduction of recorded Chapter 10 data in real-time. The standard IRIG 106 Chapter 10 recording format is quickly becoming the most commonly used data recording format in the community. As such, a lot of emphasis has been put on recording requirements including time-stamping, data multiplexing, etc. However, there are additional needs that must be considered when using Chapter 10 as the only permanent data record. It is often necessary to reproduce the original data stream exactly as it was recorded with all its timing characteristics. This paper presents various tradeoffs discovered while designing a real-time playback system for recorded chapter 10 data files. In particular, techniques such as just-enough buffering, data re-ordering, pre-processing, etc will be discussed.
