A hybrid intra-inter bi-predictive (or multi-predictive) coding mode allows both intraframe (intra) and interframe (inter) predictions to be combined together for hybrid-encoding a current macroblock or a subblock. Bi-prediction may be used also in I-pictures, combining two intra predictions that use two different intra prediction directions. A video encoder processes data representing a two-dimensional video image which has been produced by a conventional commercially available video camera. The video encoder is adapted to select, for coding a current macroblock, between an intra encoding mode, an P-frame inter encoding mode, a B-frame bi-predictive inter mode, and a hybrid intra-inter bi-predictive encoding mode. A video decoder receives and decodes a data stream that may contain a block/macroblock encoded in accordance with the hybrid intra-inter bi-predictive encoding mode.

The invention includes transmission of multiple audio data signals for several languages on a conventional radio and television carrier through the use of low bandwidth data. Error detection and correction data is included within the transmitted data. The receiver has various error compensating mechanisms to overcome errors in data that cannot be corrected using the error correcting data that the transmitter sent.

The invention is a diversity radio reception system and process of operation. At least two diversity radio signals are received each containing a sequence of corresponding data units which are each subject to an intermittent error from one to Y data units in duration wherein Y is an integer equal to at least one.
