Abstract:
Methods are provided for inter-prediction candidate index coding independent of the construction of the corresponding inter-prediction candidate list, i.e., a merging candidate list or an advanced motion vector predictor list. A maximum allowed number of inter-prediction candidates for an inter-prediction candidate list is used for encoding the inter-prediction candidate index in an encoded bit stream. The maximum allowed number may be pre-determined or may be selected by the encoder and encoded in the bit stream. A decoder may then decode the index using the maximum allowed number of inter-prediction candidates independent of the construction of the corresponding inter-prediction candidate list.

Claim (Index 1):
A video system for decoding a picture from an encoded video bit stream, comprising:\n a receiver component configured to receive the encoded video bit signal; an entropy decoding component coupled to the receiver component and configured to: decode a single maximum allowed number of merge candidates for a merge candidate list from a slice header for a slice region of the picture comprising a plurality of prediction units (PUs), wherein the single maximum allowed number of candidates for the merge candidate list is the single maximum allowed number of merge candidates for all of the plurality of prediction units; decode a merge candidate index for a prediction unit (PU) from the plurality of prediction units using the single maximum allowed number of merge candidates in the slice region wherein one less than the single maximum allowed number of merge candidates is used as a maximum codeword size for truncated unary decoding of the merge candidate index; construct a merge candidate list for the PU; an inverse quantization component coupled to the entropy decoding component and configured to de-quantize quantized transform coefficients of residual prediction units decoded from the encoded bit stream; an inverse transform component coupled to the inverse quantization component and configured to inverse transform the transform coefficients of residual prediction units from the inverse quantization component from a frequency domain to residual prediction units; a motion compensation component coupled to the entropy decoding component and configured to form reconstructed prediction units; an adder component coupled to the motion compensation component and the inverse transform component and configured to combine residual prediction units and reconstructed prediction units; a memory coupled to the adder component and configured to store picture; and a display coupled to the memory to display the picture.
