Abstract
In an example, a method of decoding video data includes determining whether a reference index for a current block corresponds to an inter-view reference picture, and when the reference index for the current block corresponds to the inter-view reference picture, obtaining, from an encoded bitstream, data indicating a view synthesis prediction (VSP) mode of the current block, where the VSP mode for the reference index indicates whether the current block is predicted with view synthesis prediction from the inter-view reference picture.

A method of decoding video data, the method comprising:
- determining whether a reference index for a current block corresponds to an inter-view reference picture;
- and
- when the reference index for the current block corresponds to the inter-view reference picture, obtaining, from an encoded bitstream, data indicating a view synthesis prediction (VSP) mode of the current block, wherein the VSP mode for the reference index indicates whether the current block is predicted with view synthesis prediction from the inter-view reference picture.
An apparatus for decoding video data, the apparatus comprising:
- a memory storing video data including a current block;
- and
- one or more processors configured to:
- determine whether a reference index for the current block corresponds to an inter-view reference picture;
- and
- when the reference index for the current block corresponds to the inter-view reference picture, obtain, from an encoded bitstream, data indicating a view synthesis prediction (VSP) mode of the current block, wherein the VSP mode for the reference index indicates whether the current block is predicted with view synthesis prediction from the inter-view reference picture.
A method of encoding video data, the method comprising:
- determining whether a reference index for a current block corresponds to an inter-view reference picture;
- when the reference index for the current block corresponds to the inter-view reference picture, generating data indicating a view synthesis prediction (VSP) mode of the current block, wherein the VSP mode for the reference index indicates whether the current block is predicted with view synthesis prediction from the inter-view reference picture;
- and
- encoding the data indicating the VSP mode in a bitstream.
An apparatus for encoding video data, the apparatus comprising:
- a memory storing video data including a current block;
- and
- one or more processors configured to:
- determine whether a reference index for a current block corresponds to an inter-view reference picture;
- when the reference index for the current block corresponds to the inter-view reference picture, generate data indicating a view synthesis prediction (VSP) mode of the current block, wherein the VSP mode for the reference index indicates whether the current block is predicted with view synthesis prediction from the inter-view reference picture;
- and
- encode the data indicating the VSP mode in a bitstream.
A non-transitory computer-readable medium having instructions stored thereon that, when executed, cause one or more processors to:
- determine whether a reference index for a current block corresponds to an inter-view reference picture;
- and
- when the reference index for the current block corresponds to the inter-view reference picture, code data indicating a view synthesis prediction (VSP) mode of the current block, wherein the VSP mode for the reference index indicates whether the current block is predicted with view synthesis prediction from the inter-view reference picture.
An apparatus for coding video data, the apparatus comprising:
- means for determining whether a reference index for a current block corresponds to an inter-view reference picture;
- and
- when the reference index for the current block corresponds to the inter-view reference picture, means for coding data indicating a view synthesis prediction (VSP) mode of the current block, wherein the VSP mode for the reference index indicates whether the current block is predicted with view synthesis prediction from the inter-view reference picture.
