Abstract:
An apparatus for decoding a surround audio signal includes a Bitstream De-multiplexer for unpacking a bitstream into spatial parameters and core parameters, a set of core decoders for decoding the core parameters into a set of core signals, a matrix derivation unit for deriving the rendering matrix from the spatial parameters and playback speaker layout information, and a renderer for rendering of the decoded core signals to playback signals using the rendering matrix.

Claim (Index 7):
An apparatus for encoding a surround audio signal, comprising:\n an audio scene analysis and spatial encoder that analyses the input signal and encodes the input signal into a number of predominant sound and a number of ambiance sound, and corresponding predominant sound parameters and ambiance parameters; a channel assignment unit that assigns the core encoders to encode the predominant sound and ambiance sound; a rendering flag determination unit that determines a rendering flag to indicate whether some data exists in a bitstream which makes encoding not practical to be implemented; a set of core encoders that encodes the generated audio signals, including both the predominant sound and ambiance sound into a set of core parameters; and a transmitter that transmits the rendering flag, predominant sound parameters, ambiance parameters, channel assignment information, and core parameters.
