## Abstract

There are provided methods and apparatus for the use of slice groups in encoding and decoding multi-view video coding (MVC) information. An apparatus (100) and method (500) are described which encodes at least two views corresponding to multi-view video content using multiple slice groups (510, 515, 520). Furthermore, an apparatus (200) and method (600) are described for decoding at least two views corresponding to multi-view video content using multiple slice groups (620).

## Claims

### Claim 1

An apparatus, comprising:
a transmitter configured to transmit at least two views corresponding to multi-view video content encoded into a single picture using multiple slice groups,
wherein the at least two views correspond to a same or similar scene, and
wherein each of the at least two views is coded as a respective separate one of the multiple slice groups.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein said transmitter is configured to transmit a Supplemental Enhancement Information message used to code each of the at least two views as the respective separate one of the multiple slice groups.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the Supplemental Enhancement Information message indicates that at least some of the multiple slice groups are motion constrained.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein said transmitter is configured to transmit a modified version of an existing Supplemental Enhancement Information message of an existing video coding standard or video coding recommendation, the existing Supplemental Enhancement Information message being modified to include slice group identifier information.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein said transmitter is configured to transmit a modified version of a Picture Parameter Set, the Picture Parameter Set being modified to signal view identifier information and slice group identifier information for the at least two views.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein said transmitter is configured to signal that each of the at least two views is independently coded, using a high level syntax element.

### Claim 7 (depends on 6)

The apparatus of claim 6, wherein the high level syntax element corresponds to at least one of a slice header level, a sequence parameter set level, a picture parameter set level, a view parameter set level, a network abstraction layer unit header level, and a level corresponding to a supplemental enhancement information message.

### Claim 8

An apparatus, comprising:
a receiver configured to receive encoded video signal data comprising at least two views corresponding to multi-view video content encoded into a single picture using multiple slice groups,
wherein the at least two views correspond to a same or similar scene, and
wherein each of the at least two views is coded as a respective separate one of the multiple slice groups.

### Claim 9 (depends on 8)

The apparatus of claim 8, wherein said receiver is configured to receive a Supplemental Enhancement Information message used to code each of the at least two views as the respective separate one of the multiple slice groups.

### Claim 10 (depends on 9)

The apparatus of claim 9, wherein the Supplemental Enhancement Information message indicates that at least some of the multiple slice groups are motion constrained.

### Claim 11 (depends on 8)

The apparatus of claim 8, wherein said receiver is configured to receive a modified version of an existing Supplemental Enhancement Information message of an existing video coding standard or video coding recommendation, the existing Supplemental Enhancement Information message modified to include slice group identifier information.

### Claim 12 (depends on 8)

The apparatus of claim 8, wherein said receiver is configured to receive a modified version of a Picture Parameter Set, the Picture Parameter Set modified to signal view identifier information and slice group identifier information for the at least two views.

### Claim 13 (depends on 8)

The apparatus of claim 8, wherein said receiver is configured to determine that each of the at least two views is independently coded, using a high level syntax element.

### Claim 14 (depends on 13)

The apparatus of claim 13, wherein the high level syntax element corresponds to at least at one of a slice header level, a sequence parameter set level, a picture parameter set level, a view parameter set level, a network abstraction layer unit header level, and a level corresponding to a supplemental enhancement information message.
