....a Real Active Service In this subsection, we discuss the execution and management of the WaveVideo multicast service [12] on an active node. The video encoding scheme of WaveVideo is based on the Wavelet transformation; it is highly scalable by supporting a variety of packet dropping policies [11]. For instance, the WaveVideo encoding allows a video stream to be thinned independently in different dimensions color depth, resolution, or frame rate. The combination of video encoding and active networking allows a video provider to distribute content to consumers with heterogeneous network ....

....Active Router Plugins [9] software architecture on the router. Active Router Plugins allows for on demand downloading and installation of a kernel plugin on the router on occurrence of a plugin identifier in a video datagram. Second, we use a wavelet based, adaptive video codec called Wave Video [11], which supports up to 50 scaling levels compared to only three levels offered by MPEG. Third, we designed and implemented a video scaling algorithm which is capable of fine tuning the video to the desired rate provided by the router based on momentary link lead patterns by performing a simple ....
....(see [10] for a discussion of a loss tolerant H.263 version) thus lack important features. Since high performance scaling is a crucial requirement, we favor a wavelet based approach called WaveVideo featuring a simple differencebased temporal encoding. B. WaveVideo Encoding WaveVideo [7] [11] encodes single video frames by furst transforming the color channels from the spatial to the frequency domain and then quantizing and compressing the decorrelated output. A two dimensional wavelet transform (WT) is applied to the image, which is implemented and approximated using iterated ....

....called transcoders) may receive a video stream and adapt it to a lower bit rate. This is done in a selective fashion where one can specify what property of the video is to be degraded in order to achieve the lower bit rate (e.g. lower resolution, no or less defined color, lower frame rate etc. [2]. # In contrast, Error Control Modules (E) do not subtract from a video stream, they rather add to it. Depending on the link s loss characteristics and built in error control mechanisms, such modules may choose to add redundancy to the channel by additional channel coding and or retransmissions ....
