The Internet of the future and next generation wireless systems are expected to carry to a large extent video of heterogeneous quality and video that is scalable encoded (into multiple layers). However, due to a lack of long traces of heterogeneous and scalable encoded video, most video networking studies are currently conducted with traces of single layer(non{scalable)encodedvideo. Inthistechnicalreportwepresentapubliclyavailable libraryoftracesofheterogeneousandscalableencodedvideo. Thetraceshavebeengenerated from over 15 videos of one hour each, which have been encoded into two layers using the temporal scalability and spatial scalability modes of MPEG{4.
