The present invention especially relates to a transmitter, a receiver, a method of transmitting video data and a method for receiving video data. The transmitter for transmitting video data comprises: A transmission section, said transmission section comprising a parser for dividing said video data into at least two classes and dividing each class into one or more blocks. Hereby, with each class there is associated a different number. Said transmission section is adapted to transmit at least one block of each class once on each communication channel of a set communication channels, the number of communication channels comprised in the respective set being given by the number associated with the respective class. Further, different communication channels correspond to different transmission times and/or different transmit paths. The receiver for receiving video data comprises: A receiving section for receiving said video data on a plurality of communication channels and generating a plurality of partial signals, each partial signal corresponding to a different communication channel. Different communication channels correspond to different transmission times and/or different receive paths. A decoding and validating section comprising a decoder for decoding a first block of said video data based on a partial signal of a first number of at least two partial signals and an error detector for determining if said decoded first block of video data is corrupted. In case said decoded first block of video data is determined to be corrupted, said decoder is configured to decode said first block of video data based on an other signal of said first number of partial signals.
