On the complexity of rate-distortion optimal streaming
GEOMETRIC INVARIANT THEORY BASED ON WEIL DIVISORS (2008)
Martin Röder, Raouf Hamzaoui, Jürgen Hausen
Abstract. Given an action of a reductive group on a normal variety, we construct all invariant open subsets admitting a good quotient with a quasiprojective or a divisorial quotient space. Our...
Efficient Rate-Distortion Optimized Media Streaming (2007)
This thesis considers the problem of finding optimal transmission strategies in rate-distortion optimized media streaming over a packet erasure channel with random delay. A compressed media stream,...
Fast List Viterbi Decoding and Application for Source-Channel Coding of Images. 2. rev. ed. (2005)
Röder, Martin, Hamzaoui, Raouf
A list Viterbi algorithm (LVA) finds n most likely paths in a trellis diagram of a convolutional code. One of the most efficient LVAs is the tree-trellis algorithm of Soong and Huang. We propose a...

JOURNAL, VOL., NO., YEAR 2 A list Viterbi algorithm (LVA) finds n most likely paths in a trellis diagram of a convolutional code. One of the most efficient LVAs is the tree-trellis algorithm of Soong...
On the Complexity of Rate-Distortion Optimal Streaming of Packetized Media (2004)
Fachbereich Informatik Und Informationswissenschaft, Martin Röder, Martin Roder, Raouf Hamzaoui, Raouf Hamzaoui, Raouf Hamzaoui, ...
We consider the problem of optimal rate-distortion streaming of packetized multimedia data in the context of sender-driven transmission over a single-QoS network using feedback and retransmissions....
Effiziente Viterbi Decodierung und Anwendung auf die Bildübertragung in gestörten Kanälen (2002)
Faltungscodes ist der Viterbi Algorithmus, der aus einem empfangenen, codierten Datenblock die Daten ermittelt, die der Sender mit höchster Wahrscheinlichkeit gesendet hat. Auf dem Viterbi...
Effiziente Viterbi Decodierung und Anwendung auf die Bildübertragung in gestörten Kanälen (2002)
Faltungscodes dienen dem Schutz vor Fehlern bei der Übertragung von Daten. Ein Verfahren zur Decodierung von Faltungscodes ist der Viterbi Algorithmus, der aus einem empfangenen, codierten...
