TL;DR
Two dynamic QOS control schemes: a self-stabilization scheme and a QOS manager-based scheme are evaluated using a QuickTime movie player running on Real-Time Mach.
Abstract
This paper presents dynamic QOS control schemes based on real-time threads. A real-time thread is based on an explicit declaration of timing attributes, such as start time, deadline, period, and its deadline handler. Two dynamic QOS control schemes: a self-stabilization scheme and a QOS manager-based scheme are evaluated using a QuickTime movie player running on Real-Time Mach.

The objective of Real-Time Mach is to develop a real-time version of the Mach kernel which provides users with a predictable and reliable distributed real- time computing environment.
Object-oriented real-time language design: constructs for timing constraints
136 Citations1990Yutaka Ishikawa, Hideyuki Tokuda
RTC++ is an extension of C++ and its features are to specify i) a real-time object which is an active entity, ii) timing constraints in an operation as well as in statements, and iii) a periodic task with rigid timing constraints.
A continuous media transport and orchestration service
109 Citations1992Andrew T. Campbell, Geoff Coulson +2 more
This paper describes an application level service, known as an orchestrator, which performs synchronisation functions over multiple related transport connections, and outlines the design and implementation of a continuous media transport service which meets the identified requirements.

Processor capacity reserves: an abstraction for managing processor usage
49 Citations2002Clifford W. Mercer, Stefan Savage +1 more
The reservation mechanism provides a way for application programs to specify their reservation requests and incorporates a scheduling framework which supports an admission control policy and the scheduler enforces reservations by relegating reserves to a time-sharing pool after their reservations have been consumed.
RT-IPC: an IPC extension for real-time mach
29 Citations1993Takuro Kitayama, Hideyuki Tokuda +1 more
The results show that RT-IPC can reduce priority inversion and improve CPU utilization for real-time applications.
QuickTime: an extensible standard for digital multimedia
20 Citations2003Eric M. Hoffert, M. Krueger +14 more
QuickTime is an extensible standard for digital multimedia which establishes a foundation for the representation of time-based objects and file formats, still image and video compression techniques, human interface conventions, and application programming interfaces that brings dynamic media to a broad range of applications.
