Generalized scalability for video coder based on video objects

A method of decoding coded video data, the coded video data including coded first and second video object layers for a video object, the method comprising:

• receiving the coded video data,
• decoding the coded first video object layer the first video object layer including a first plurality of video object planes,
• decoding the coded second video object layer, the second video object layer including a second plurality of video object planes, and
• generating a decoded video object based upon the decoded first and second video object layers.

A method of decoding coded video data, the coded video data including coded first and second video object layers, the method comprising:

• receiving the coded video data,
• distinguishing the coded first video object layer from the coded video data the first video object layer including a first plurality of video object planes,
• decoding the coded first video object layer the second video object layer including a second plurality of video object planes, and
• generating a decoded video object based upon the decoded first video object layer.

A method of coding video information, comprising:

• identifying a video object in the video information,
• representing the video object as a series of video object planes,
• coding a first part of the video object planes as a base video object layer, and
• coding a second part of the video object planes as an enhancement video object layer.

A scalable video coding method providing generalized scalability, comprising:

• identifying a video object from the video information,
• representing the video object as a series of video object planes,
• coding a first part of the video object planes as a base video object layer, and
• coding a second part of the video object planes as an enhancement video object layer, the coding of the coded base video object layer as a candidate for prediction using a single syntax applicable for both temporal and spatial scalability.
