“…DEMUX re-orders the packets, merges UDP packets with TCP packets, and sends them to the Decoder, which is implemented using FFmpeg [22]. The proposed FDPS was implemented within Open Evaluation Framework for Multimedia Over Networks (OEF-MON) [23], which integrates the DirectShow multimedia module [24] and the QualNet network simulator [25]. A simplified diagram of OEFMON is shown in Fig.…”

High Definition video streaming over WLANs faces many challenges because video data requires not only data integrity but also frames have strict playout deadline. Traditional streaming methods that rely solely on either UDP or TCP have difficulties meeting both requirements because UDP incurs packet loss while TCP incurs delay. This paper proposed a new streaming method called Flexible Dual-TCP/UDP Streaming Protocol (FDSP) that utilizes the benefit of both UDP and TCP. The FDSP takes advantage of the hierarchical structure of the H.264/AVC syntax and uses TCP to transmit important syntax elements of H.264/AVC video and UDP to transmit non-important elements. The proposed FDSP is implemented and validated under different wireless network conditions. Both visual quality and delay results are compared against pure-UDP and pure-TCP streaming methods. Our results show that FDSP effectively achieves a balance between delay and visual quality, thus it has advantage over traditional pure-UDP and pure-TCP methods.

“…The simulation portion of our evaluation was performed using OEFMON [22]. OEFMON integrates the DirectShow multimedia framework and the QualNet [25] network simulator, resulting in a versatile, modular framework for evaluating video quality with respect to network performance.…”

“…The testbed consisted of three laptops that serve as receivers and a laptop, iPad2, and iPod Touch as a set of senders. The simulation was carried out using the Open Evaluation Framework for Multimedia Over Networks (OEFMON) [22], which was developed at Korea Advanced Institute of Science and Technology (KAIST) and integrates a multimedia module and a network simulator. The OEFMON tool allows us to not only study networks that are difficult to create with testbeds, but also facilitates evaluation of perceptual video quality as well as network performance to provide additional insight into the issues that take place within the network.…”

Abstract-Many challenges and limitations stand in the way of streaming high resolution video content over a wireless network. A shift towards the 60-GHz band is taking place in order to accommodate for current High Definition streaming demands. However, today's Wi-Fi networks are able to provide the necessary bandwidth with the help of compression. In this paper we evaluate the effectiveness of streaming video over wireless LANs using the H.264 codec. Our study shows that streaming HD content wirelessly over 802.11n is a viable option. However, perceptual quality of video is affected by the amount of background traffic and the presence of interfering nodes, i.e., hidden nodes.

“…Furthermore, we differentiate the delay budget based on the priority of video frames to reduce distortion and error propagation especially in a congested network. The performance of our scheme is evaluated by Open Evaluation Frame work for Multimedia Over Networks (OEFMON) [8] to demonstrate our scheme significantly enhances the video quality in terms of end-toend delay, frame loss ratio and PSNR. The evaluation results demonstrate that our scheme can achieve 20% lower end-to-end delay and 60% less frame loss ratio with 32% better PSNR compared to the existing cross-layer mapping schemes.…”

The recent proliferation of mobile devices increases the demand for high-quality real-time video services in wireless network. However, the characteristics of wireless medium such as interferences and ease of congestion make it difficult for the delivered video to be played out in a timely manner.The latency introducedby those wireless characteristics severely degrades the perceptual quality of real-time videodue to intermittent playoutat the client side. In this paper, we propose adelay-constrained adaptive early drop scheme for real-time video delivery over IEEE 802.11 wireless networks. In our scheme, an intermediate router forcibly discards the less important video packetswhich are expected not to be played out in time. The simulation results demonstratethat the proposed scheme can achieve 20% lower endto-end delay and60% less frame loss ratio with32% better Peak Signal-to-Noise Ratio (PSNR) compared to the existing crosslayer mapping schemes.
