Abstract

A technique that permits an earlier start of the decoding and play out of media frames received via a point-to-multipoint transmission is described. The media frames comprise frames of a first type that cannot be decoded without knowledge of supplemental information and frames of a second type that include the supplemental information. According to a method aspect of this technique, frames of the first type are received and immediately buffered without waiting for reception of a frame of the second type. In a next step, a request message requesting supplemental information required for a decoding of the buffered frames of the first type is sent. Upon receipt of the requested supplemental information, the buffered frames are decoded based on the received supplemental information.
