Abstract
A three dimensional [3D] video signal (21) comprises a first primary data stream (22) representing a left image to be displayed for the left eye of a viewer and a second primary data stream representing a right image to be displayed for the right eye of the viewer for rendering 3D video data exhibiting a nominal depth range. For enabling overlaying auxiliary image data on the 3D video data at an auxiliary depth in the nominal depth range a secondary data stream (23) is included in the signal. The secondary data stream is displayed, during overlaying, for one of the eyes instead of the respective primary data stream for rendering the 3D video data exhibiting a modified depth range farther away from the viewer than the auxiliary depth.
Claims15
Method of providing a three dimensional [3D] video signal, the method comprising generating the 3D video signal by
- including a first primary data stream representing a left image to be displayed for the left eye of a viewer and a second primary data stream representing a right image to be displayed for the right eye of the viewer for rendering 3D video data exhibiting a nominal depth range,
- and, for enabling overlaying auxiliary image data on the 3D video data at an auxiliary depth in the nominal depth range,
- including a secondary data stream to be displayed for one of the eyes instead of the respective primary data stream for rendering the 3D video data exhibiting a modified depth range farther away from the viewer than the auxiliary depth.
Method of processing a 3D video signal, the method comprising
- retrieving from the 3D video signal a first primary data stream representing a left image to be displayed for the left eye of a viewer and a second primary data stream representing a right image to be displayed for the right eye of the viewer for rendering 3D video exhibiting a nominal depth range,
- retrieving from the 3D video signal a secondary data stream to be displayed for one of the eyes instead of the respective primary data stream for rendering the 3D video exhibiting a modified depth range farther away from the viewer than an auxiliary depth,
- providing auxiliary data, and
- overlaying, at a depth closer to the viewer than the auxiliary depth, the auxiliary image data on the 3D video data based on the secondary data stream.
3D source device (40) for providing a 3D video signal (41), the 3D source device comprising processing means (42) for generating the 3D video signal by
- including a first primary data stream representing a left image to be displayed for the left eye of a viewer and a second primary data stream representing a right image to be displayed for the right eye of the viewer for rendering 3D video data exhibiting a nominal depth range,
- and, for enabling overlaying auxiliary image data on the 3D video data at an auxiliary depth in the nominal depth range,
- including a secondary data stream to be displayed for one of the eyes instead of the respective primary data stream for rendering the 3D video data exhibiting a modified depth range farther away from the viewer than the auxiliary depth.
3D processing device (50) for processing a 3D video signal, the device comprising receiving means (51,58,59) for receiving the 3D video signal, and
- processing means (52,53) for
- retrieving from the 3D video signal a first primary data stream representing a left image to be displayed for the left eye of a viewer and a second primary data stream representing a right image to be displayed for the right eye of the viewer for rendering 3D video exhibiting a nominal depth range,
- retrieving from the 3D video signal a secondary data stream to be displayed for one of the eyes instead of the respective primary data stream for rendering the 3D video exhibiting a modified depth range farther away from the viewer than an auxiliary depth,
- providing auxiliary data, and
- overlaying, at a depth closer to the viewer than the auxiliary depth, the auxiliary image data on the 3D video data based on the secondary data stream.
3D video signal for transferring 3D video data, the 3D video signal comprising
- a first primary data stream (22) representing a left image to be displayed for the left eye of a viewer and a second primary data stream representing a right image to be displayed for the right eye of the viewer for rendering 3D video data exhibiting a nominal depth range,
- and, for enabling overlaying auxiliary image data on the 3D video data at an auxiliary depth in the nominal depth range,
- a secondary data stream (23) to be displayed for one of the eyes instead of the respective primary data stream for rendering the 3D video data exhibiting a modified depth range farther away from the viewer than the auxiliary depth.
