METHOD FOR SENDING A MEDIA DATA STREAM AND METHOD FOR RECEIVING AND CREATING A RECONSTRUCTED MEDIA DATA STREAM, AND ASSOCIATED TRANSMISSION APPARATUS AND RECEPTION APPARATUS

摘要

A method sends a media data stream in which encoding of the media data stream generates a first data stream and at least one second data stream such that the first data stream represents the media data stream in a basic quality and one or more second data streams together with the first data stream represent the media data stream in an improved quality over the basic quality, in which data in the first and second data streams are respectively sent using a transmission channel allocated in predefined fashion. Another method receives and creates a reconstructed media data stream, in which the reconstructed media data stream is reconstructed from a first data stream or from the first and at least one second data stream, in which data from the first data stream or from the first and at least one second data stream are received in a respective transmission channel allocated in predefined fashion, where the reconstructed media data stream is generated by decoding the data in the first data stream or by decoding the data in the first and at least one second data stream.
