It does not handle data in pull mode (File, HTTP and FTP) but uses RTSP/RTP (and Files). It uses RTSP as control protocol to communicate with possible streaming servers. The video data is transported via RTP. -The KOM (S) Streaming System provides a ser ver, a client, and a proxy cache for audio/video streaming.

Description: All three, Discrete Wavelet Transform (DWT) - Singular
Value Decomposition (SVD) and Adaptive Tabu Search
(ATS) have been used as mathematical tools for embedding
data into an audio signal. In this paper, we present a new
robust audio watermarking scheme based on DWT-SVD and
ATS. After applying the DWT to the cover audio signal, we
map the DWT coefficients, and apply the SVD, we search for
the optimal intensity of audio watermarking by using the
ATS. Experimental results show that the watermarking
method performs well in both security and robustness to
many digital signals processing, such as filtering,
cropping, mp3 and random noise.

Description: Along with investigating similarity metrics between audio
material, the topic of robust matching of pairs of audio content
has gained wide interest recently. In particular, if this matching
process is carried out using a compact representation of the audio
content ("audio fingerprint"), it is possible to identify unknown
audio material by means of matching it to a database with the
fingerprints of registered works. This paper presents a system for
reliable, fast and robust identification of audio material which can
be run on the resources provided by today s standard computing
platforms. The system is based on a general pattern recognition
paradigm and exploits low level signal features standardized
within the MPEG-7 framework, thus enabling interoperability on
a world-wide scale.
