Abstract
A digital broadcast transmitter and a digital broadcast receiver for 3-dimensional (3D) broadcasting, and methods for processing a steam thereof. The digital broadcast transmitter includes: a stream processor which processes first and second data parts of an input signal differently from each other, wherein the first data part is to constitute a 2-dimensional (2D) image, and the second data part is to constitute a 3D image; and a transmitter which transmits a transport stream (TR) including the first and second data parts processed by the stream processor.
Claims27
A digital broadcast transmitter, comprising:
- a stream processor which processes first and second data parts of an input signal differently from each other;
- and
- a transmitter which transmits a transport stream (TS) comprising the first and second data parts processed by the stream processor,
- wherein the first data part is to constitute a 2-dimensional (2D) image, and
- the second data part is to constitute a 3-dimensional image (3D) image.
A method for processing a stream in a digital broadcast transmitter, the method comprising:
- providing a first data part which is to constitute a 2-dimensional (2D) image and a second data part which is to constitute a 3-dimensional (3D) image;
- processing the first and second data parts differently from each other;
- and
- transmitting a transport stream (TS) comprising the processed first and second data parts.
A digital broadcast receiver, comprising:
- a receiver which receives a transport stream (TS) comprising first and second data parts, wherein the first data part is to constitute a 2D image, and the second data part is to constitute a 3D image;
- a separator which separates the first and second data parts from the TS;
- a first processor which processes the first data part;
- a second processor which processes the second data part;
- a display unit which displays a 3D image using the first data part processed by the first processor and the second data part processed by the second processor;
- and
- a controller which controls the display unit to display a 2D image using the first data part if the second data part cannot be reproduced.
A method for processing a stream in a digital broadcast receiver, the method comprising:
- receiving a transport stream (TS) which comprises first and second data parts, wherein the first data part is to constitute a 2D image, and the second data part is to constitute a 3D image;
- separating the first and second data parts from the TS;
- and
- processing the first and second data parts using different methods.
A digital broadcast transmitter, comprising:
- a stream processor which generates an orthogonal frequency division multiplexing (OFDM) signal comprising a plurality of sub-carriers;
- and
- a transmitter which transmits the OFDM signal,
- wherein the OFDM signal comprises at least one first layer comprising a first data part for constituting a 2D image and at least one second layer comprising a second data part for constituting a 3D image,
- wherein at least one of a modulation method and a coding rate is applied to the at least one first layer differently from a modulation method and a coding rate applied to the at least one second layer.
A digital broadcast receiver, comprising:
- a receiver which receives an OFDM signal comprising a plurality of sub-carriers;
- and
- a demodulator which demodulates the OFDM signal,
- wherein the OFDM signal comprises at least one first layer comprising a first data part for constituting a 2D image and at least one second layer comprising a second data part for constituting a 3D image,
- wherein the at least one first layer is processed by a different modulation method and coding rate from that of the at least one second layer.
