End-to-end transmission of scalable video contents: performance evaluation over EvalSVC—a new open-source evaluation platform

Abstract

Nevertheless, multimedia service research and industry community have not been able to fully utilize the entire potential of this video coding standard because of the lack of a platform for evaluating the end-to-end transmission of SVC-contents. EvalSVC aims to foster SVC-based applications and research in multimedia services. It is capable of evaluating the end-to-end transmission of SVC bit-streams encoded with enhanced features (spatial, temporal, SNR, combined scalability). The output results are both objective and subjective metrics of the video transmission. Interfaces with real networks and an overlay simulation platform are presented. Through these interfaces, the transmission performance of different types of SVC scalability and AVC bit-streams on bottle-neck conditions and overlay network will be evaluated. This evaluation is new because it is conducted on the end-to-end transmission of SVC contents and not on the coding performance. The bottleneck network environment is set up for evaluation because this realistic and very common network condition usually causes serious problems for video transmission and multimedia services. The overlay network is used for evaluation because it is a future transportation environment for multimedia content delivery. The results show that, both in bottle-neck network conditions and on the overlay network environment, SVC transmission outperforms AVC transmission and SNR scalability has the highest transmission performance. Through these end-toend transmission performance evaluations over EvalSVC, we can conclude that, indeed SVC achieves its objectives of improving video transmission over realistic network conditions.

Simulation and experimental testbed for adaptive video streaming in ad hoc networks

“…However, the solutions proposed until now for MANETs have not assessed in detail the option of adapting the bit rate, by removing or adding SVC layers, according to the estimation of the available bandwidth. Furthermore, the existing tools for evaluating the developed solutions for SVC streaming (such as EvalSVC [17] and myEvalSVC [18]) do not enable adaptive streaming operation and therefore, the entire SVC stream is always transmitted. This operation mode of the aforementioned evaluation frameworks limits the utilization of the layered schemed of SVC.…”

Performance Evaluation of Scalable Video Streaming in Mobile Ad hoc Networks

“…Recientemente, han sido desarrolladas algunas herramientas software para simular la transmisión y evaluación de video escalable. Por ejemplo, está la plataforma SVEF (Scalable Video-streaming Evaluation Framework) [19] [20] y Ke [21], respectivamente. Estas plataformas de simulación están integradas al simulador de redes NS-2 y por tanto, permiten simular la transmisión de video SVC usando las diferentes tecnologías de red incluidas en dicho simulador.…”

SVCEval-RA: an evaluation framework for adaptive scalable video streaming

“…Moreover, it does not take the spatial scalability into consideration and only supports SVC videos with a single dependency layer. Other evaluation platforms for scalable video streaming are EvalSVC (Evaluation of SVC) and myEvalSVC simulation framework, which were developed by Le et al [17] and Ke [18] respectively. These simulations platforms extend the EvalVid framework in order to provide a simulation framework where SVC video transmissions can be evaluated over a general network simulator as NS-2.…”
