Experimental Results of Mpeg-2 Coded Video Transmission over a Noisy Satellite Link
نویسندگان
چکیده
The results of a transmission experiment of MPEG-2 coded video data over a satellite link affected by noise are presented. The goal was to investigate under which conditions this type of transmission is economically feasible. The scalability feature of the MPEG-2 encoder was used to produce different bitstreams of the same video sequence. We wanted to verify the best combinations among video and channel codings in presence of attenuation on the satellite link, in order to optimize the bandwidth utilization for a requested image quality. The limitations imposed by the satellite equipment at our disposal are outlined. In spite of these limitations, the results obtained give indications about how to deal with different quality of service requirements and highlight the flexibility of the scalable video coding.

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...

Integrated services over a shared satellite channel need a MAC protocol that is able to deal with real-time traffic without substantially affecting the efficiency of the shared medium. Because of its bursty nature, MPEG coded VBR video transmission is one of the most challenging real-time applications. In this paper we analyze the statistical performance of a simple allocation method for VBR tr...
متن کاملDynamic Rate Shaping on MPEG-2 Video Streams for Bandwidth Saving on a Faded Satellite Channel
In a previous work, we studied how to send a video stream over a noisy satellite channel using the scalability features of the MPEG-2 standard. The base and the enhancement flows were sent with different levels of protection (bit and coding rates) in order to deal with the channel degradation. In this paper, we add Dynamic Rate Shaping (DRS), thus obtaining a greater flexibility in the choice o...

We consider the performance of MPEG-II compressed video when transmitted over noisy channels. We present the results of bit sensitivity and resynchronisation sensitivity measurements , and propose techniques for substantially improving the resilience of MPEG-II to transmission errors without the addition of any extra redundancy into the bitstream. We nd that it is errors in variable length enco...

This paper shows how the adoption of a Dynamic Rate Shaping (DRS) to variable bit rate (VBR) MPEG-2 (Motion Pictures Expert Group-2) coded video data, in addition to different levels of data protection, adds more flexibility in the way a video data stream can be sent over a faded satellite channel. DRS allows the satellite bandwidth required to be continuously trimmed, within a certain range. A...
