Considerations When Evaluating and Playout System Implementation

چکیده
www.grassvalley.com Choices for a playout solution have usually fallen between implementing a traditional automation system that links together a complex collection of many devices from different providers, or a basic single-channel box consisting of a standard PC with cards. There is now a viable alternative that brings a file-based, networked, and scalable approach to the task of well managed, consolidated delivery of on-air content that includes video, audio, secondary media, and graphics.

Representation Switch Smoothing for Adaptive HTTP Streaming
When an adaptive media streaming system has to switch from one representation of the content to another, the switch causes viewer distraction. We introduce the concept of representation switch smoothing for alleviating the distraction and improving the overall quality of experience. As adaptive HTTP streaming systems typically deploy video buffers on the client side, the adaptation decision is ...
متن کاملAN EFFICIENT VIDEO RENDERING SYSTEM FOR REAL−TIME ADAPTIVE PLAYOUT BASED ON PHYSICAL MOTION FIELD ESTIMATION (WedAmPO4)
In this paper we present a software implementation of an Adaptive Playout System for video rendering. In our opinion the system can be useful for the rendering of multimedia material that is delivered (in single or multi−cast way) to the final user(s) over a “best effort” network that is not able to guarantee a constant delay in delivering the data packets. The proposed solution is an alternati...
متن کاملAn automatic test case generator for evaluating implementation of access control policies
One of the main requirements for providing software security is the enforcement of access control policies which aim to protect resources of the system against unauthorized accesses. Any error in the implementation of such policies may lead to undesirable outcomes. For testing the implementation of access control policies, it is preferred to use automated methods which are faster and more relia...
متن کاملQoS Adaptive Transports: Delivering Scalable Media to the Desk Top
By trading off temporal and spatial quality with available bandwidth, or manipulating the playout time of continuous media in response to variation in delay, audio and video flows can be made to adapt to fluctuating network conditions with minimal perceptual distortion. In this paper we describe the implementation of an adaptive transport system that incorporates a QoSoriented API and a range o...
متن کامل-Sets for Optimized Reactive Adaptive Playout Management in Distributed Multimedia Database Systems
A novel database system service called playout management service which performs multimedia presentations was proposed recently. In distributed multimedia database systems without end-to-end guarantees, such a playout management service faces the potential problem that system performance can become insufficient when realizing a stored presentation. This problem can be overcome by making the pla...
