MPEG-2 video transmission using the HIPERLAN/2 WLAN standard

At present, Wireless Local Area Networks (WLANs) supporting broadband multimedia communication are being developed and standardized around the world in the 5GHz band. Systems such as IEEE802.1 l a and HIPERLAN/2 will provide data rates up to 54 Mbps. Highly compressed data such as video are extremely sensitive to the errors that are commonly encountered in wireless channels. This paper addresse...

Real-Time DMB Video Encryption in Recording on PMP

At July 2008, the nationwide DMB (Digital Multimedia Broadcasting) has got started. As DMB device's volume of sales has been over 12 million already, the development of rapidly changing network systems has increased the dangers of infringing the copyright of DMB contents. For solving this problem, we suggest that real-time encryption algorithm without additional expenses, and implemented that o...

Impact of ATM traffic control on MPEG-2 video quality

In this paper, a performance study of controlled MPEG-2 video traffic over an ATM network is presented. ATM networks are able to support variable bit rate (VBR) video sources. However, to implement QoS contract enforcement, traffic policers such as a Leaky Bucket need to be incorporated in order to change the VBR characteristics of a video stream. Our study investigates the video quality achiev...
