Abstract
(A1) Es wird eine Vorrichtung zum Zuweisen von Uebertragungssymbolen zu einem Mediadatenstrom von Informationssymbolen beschrieben, wobei der Mediadatenstrom einen ersten Teilstrom zur Darstellung eines Mediainhaltes in einer Basisqualitaet und einen zweiten Teilstrom mit Zusatzdaten zur Darstellung des Mediainhaltes zusammen mit dem ersten Teilstrom in einer verbesserten Qualitaet umfasst. Die Vorrichtung weist dabei eine erste Einrichtung zum Zuweisen erster Uebertragungssymbole zu den Informationssymbolen des ersten Teilstromes auf und eine zweite Einrichtung zum Zuweisen zweiter Uebertragungssymbole zu den Informationssymbolen des zweiten Teilstroms, wobei die ersten Uebertragungssymbole gegenueber den zweiten Uebertragungssymbolen ueber einen Uebertragungskanal mit geringerer Fehlerwahrscheinlichkeit uebertragbar sind.

 

WO 2009153068 A2 UPAB: 20100107 NOVELTY - The transmitter has a device to assign transmission symbols to information symbols of a partial stream, where the symbols are processed in a data processing block (510). Another device for assigning another transmission symbols to the information symbols of another stream. The former transmission symbols are sent via a transmission channel having a lower error probability than a channel via which the latter transmission symbols are sent. A third device that assigns radio resource is adjusted to assign the resource to the transmission symbols to balance variable data rates of the streams. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for assigning a radio resource to transmission symbols (2) a computer program with a program code for implementing the method for assigning the radio resource to the transmission symbols (3) a device for estimation of the media data stream based on a stream of receiving symbols (4) a receiver with a device for estimation of the media data stream (5) a method for estimation of the media data stream based on the stream of receiving symbols (6) a computer program with a program code for implementing the method for estimation of the media data stream based on the stream of receiving symbols. USE - Transmitter for use in a system i.e. mobile radio transmission system e.g. universal mobile telecommunication system, high speed packet access system and third generation long term evolution system, for transmitting transmission symbols (all claimed) e.g. media data stream and TV program, in a wireless radio network such as digital video broadcasting-terrestrial, European telecommunications standards institute EN300744V1 5.1 digital video broadcasting network. ADVANTAGE - The transmitter enables modulating of the partial stream in a scalable coding method in a different manner. The transmitter enables using of the radio resources in an efficient manner, while the radio resources are adapted to the significance of the partial streams. The transmitter permits achieving of high video band-width with reliability and range of coverage via geometric spreading, space-time-coding and adaptation of the modulation method. The transmitter is provided with a mobile radio infra structure, which is operated with reduced transmitting power. The transmitter enables achieving of adaptive, flexible and reliable radio broadcasting transmission to multiple users.
