Abstract

A system for displaying N multimedia streams, including multiple pairs of viewing spectacles and a displaying medium. The system obtains N multimedia streams, each stream including two multimedia substreams among 2×N multimedia substreams, and has N sources generating the 2×N substreams on the displaying medium. Each source has an encoder for coding two of the 2×N multimedia substreams, each substream being coded with a set of N coding modes each using a specific set of at least two states, having at least 2^N possible combinations of states, each substream being coded with one of the possible combinations of states in order to visualize a given stream from the N multimedia stream. At least one pair spectacles includes a decoder for decoding, for each eyepiece, one of the substreams of the given stream and having N decoding modes corresponding to the N coding modes used for coding the substreams.

Claims

1. A system for viewing N multimedia streams, with N≧

2, comprising;

a plurality of pairs of viewing goggles, each pair of goggles comprising two eye-pieces;

a viewing platform;

means for obtaining N multimedia streams, each multimedia stream comprising two multimedia sub-streams among 2×

N multimedia sub-streams;

N sources adapted to generate and display said 2×

N multimedia sub-streams on said viewing platform, each of the two multimedia sub-streams of a same multimedia stream being associated with a distinct eye-piece among the two eye-pieces of a same pair of goggles, each source comprising an encoder configured to encode two of said 2×

N multimedia sub-streams, each multimedia sub-stream being encoded with a group of N encoding modes each using an own set of at least two states, having at least 2^N possible combinations of states, each multimedia sub-stream being encoded with one of the possible combinations of states,

wherein at least one pair of the goggles comprises, to view a given stream among said N multimedia streams, a decoder configured to carry out, for each eye-piece, a decoding of one of the two sub-streams of said given stream with a group of N decoding modes corresponding to the group of N encoding modes used to encode said sub-stream, and with the combination of states used to encode said sub-stream.

2. The system for viewing according to claim 1 wherein said group of N encoding modes use each mode uses an own set of two states.

3. The system for viewing according to claim 1, wherein the N encoding modes of said group belong to the group consisting of:

a temporal encoding,

a polarization encoding,

a spectral encoding.

4. The system for viewing according to claim 1, wherein the N encoding modes of said group comprise at least one passive encoding mode and at least one active encoding mode.

5. The system for viewing according to claim 1, wherein the N modes of encoding of said group comprise only passive encoding modes.

6. The system for viewing according to claim 1, wherein the N modes of encoding of said group comprise only active encoding modes.

7. The system for viewing according to claim 1, comprising, to view a given stream among said N multimedia streams, means for transmitting a configuration signal indicating, for each eye-piece, said group of the N encoding modes used to encode one of the sub-streams of said given stream, and the combination of states used to encode said sub-stream,

and wherein said at least one pair of the goggles comprises means for receiving said configuration signal.

8. The system for viewing according to claim 1, wherein each source generates two multimedia sub-streams of a same multimedia stream, associated with the two eye-pieces of a same pair of the goggles.

9. The system for viewing according to claim 1, wherein said N sources comprise an interlacer configured to carry out an interlacing of the 2×

N multimedia sub-streams of said N multimedia streams.

10. A source adapted for a system for viewing N multimedia streams, with N≧

2, and furthermore comprising a plurality of pairs of viewing goggles and a viewing platform, each multimedia stream comprising two multimedia sub-streams among said 2×

N multimedia sub-streams, said source being adapted to generate and display two multimedia sub-streams among said 2×

N multimedia sub-streams on said viewing platform, each of the two multimedia sub-streams of a same multimedia stream being associated with a distinct eye-piece among the two eye-pieces of a same pair of goggles, wherein said source comprises;

an encoder configured to encode two of said 2×

N multimedia sub-streams, each multimedia sub-stream being encoded with a group of N encoding modes each using an own set of at least two states, having at least 2^N possible combinations of states, each multimedia sub-stream being encoded with one of the possible combinations of states.

11. A pair of goggles adapted for a system for viewing N multimedia streams, with N≧

2, and furthermore comprising a plurality of pairs of viewing goggles and a viewing platform, each multimedia stream comprising two multimedia sub-streams among said 2×

N multimedia sub-streams, said pair of goggles comprising;

two eye-pieces; and

a decoder configured to carry out, for each eye-piece, a decoding of one of the sub-streams of said given stream with a group of N decoding modes corresponding to a group of N encoding modes used to encode said sub-stream and with a combination of states used to encode said sub-stream, each encoding mode using a own set of at least two states, said group having at least 2^N possible combinations of states, wherein the decoding enables viewing a given stream among said multimedia streams on said viewing platform.
