Abstract:
1. Apparatus for transmitting media information comprising: an encoder for encoding at least one media stream; a packetizer for forming packets from the encoded media stream, the packets containing application data units, the application data units having a decoding order; a packet block generator for generating at least two blocks from the packets; an organizer for organizing the packets within a block of the at least two blocks into a first group and a second group, the first group being decodable without reception of said second group; an orderer for arranging the transmission order of the packets of said first group succeeding packets of said second group such that the application data units in the transmission order are at least partly in a different order than the decoding order; and a transmitter for transmitting the packets according to the transmission order, wherein said media stream comprises at least a video stream and an audio stream, said encoder comprising a video encoder and an audio encoder; wherein said video encoder is adapted to encode the video stream to form coded pictures, said audio encoder is adapted to encode the audio stream to form encoded audio, and said organizer is adapted to organize the encoded audio into said first group and the coded pictures into said second group, wherein said encoder is adapted to encode the video stream to form coded pictures, and said organizer is adapted to organize the coded pictures into a reference picture group and a non-reference picture group, the reference picture group being decodable without reception of the non-reference picture group.
