Video robustness using spatial and temporal diversity

A receiver (2) for receiving video data comprising

• a receiving section (24) 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 corresponding to different transmission times and/or different receive paths (PS1, PS2, P1, P2, P3, P4, P5, P6);
• and
• a decoding and validating section (26) comprising
• a decoder (48) 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 (50) for determining if said decoded first block of video data is corrupted;
• whereby,
• 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.

A method of transmitting video data comprising steps of

• dividing (S21) said video data into at least two classes and each class into one or more blocks, whereby with each class there is associated a different number;
• and
• transmitting (S22) at least one block of each class once on each communication channel of a set of communication channels, the number of communication channels comprised in the respective set being given by the number associated with the respective class;
• whereby
• different communication channels correspond to different transmission times and/or different transmit paths (PS1, PS2, P1, P2, P3, P4, P5, P6).

A method of receiving video data comprising steps of

• receiving video data on a plurality of communication channels,
• generating (S1) a plurality of partial signals, each partial signal corresponding to a different communication channel, different communication channels corresponding to different transmission times and/or different receive paths (PS1, PS2, P1, P2, P3, P4, P5, P6);
• decoding (S1) a first block of said video data based on a partial signal of a first number of at least two partial signals;
• determining (S2) if said decoded first block of video data is corrupted;
• and,
• in case yes, decoding (S3) said first block of video data based on an other signal of said first number of partial signals.
