Patent ID: 8600530

Claim:
A method of determining a spatial coding mode for audio data, the audio data being coded and sent by a sender entity ( 20 ) to a receiver terminal ( 10 ) adapted to receive audio data in one or more available reproduction formats, the sender entity being adapted to code data according to at least one spatial coding mode, wherein said method comprises the steps of: the receiver terminal ( 10 ) indicating ( 1 ) to the sender entity ( 20 ) the one or more available reproduction formats of the receiver terminal in a given order of preference; the sender entity ( 20 ) determining a mode for spatial coding of the audio data compatible with one of the reproduction formats indicated by the receiver terminal, taking into account the given order of preference; and the sender entity ( 20 ) indicating ( 2 ) to the receiver terminal ( 10 ) the reproduction format of the receiver terminal which is compatible with the determined mode for spatial coding in order for the receiver terminal to spatially decode received audio data by using a spatial decoding adapted to the compatible reproduction format.
