Image providing method, and image providing apparatus, display apparatus, and image providing system using the same

An image providing method, comprising:

• receiving compressed images of two channels;
• decompressing the compressed images of two channels;
• splitting the decompressed images of two channels into an image of a first channel and an image of a second channel;
• and
• outputting the image of the first channel and the image of the second channel alternately.

An image providing apparatus, comprising:

• a receiver which receives a combined image comprising a first image and a second image compressed in a predetermined direction and multiplexed;
• a decompressor which decompresses the combined image;
• a demultiplexer which demultiplexes the decompressed image, and restores the demultiplexed image to the first image and the second image;
• and
• a controller which outputs the first and the second images alternately.

A display apparatus, comprising:

• a receiver which receives compressed images of two channels;
• a controller which decompresses the compressed images of two channels, and splits the decompressed images into an image of a first channel and an image of a second channel;
• and
• a display which outputs the image of the first channel and the image of the second channel alternately.

An image providing system, comprising:

• an image generating apparatus which compresses a first image and a second image in a predetermined direction, generates a combined image by multiplexing the compressed first image and the compressed second image, and transmits the combined image;
• an image providing apparatus which receives the combined image from the image generating apparatus, decompresses the combined image, restores the decompressed image into a first image and a second image by demultiplexing the decompressed image, and outputs the first image and the second image alternately;
• and
• shutter glasses which are synchronized with a time at which the first image and the second image are alternately output, and alternatively open and close a left eye glass and a right eye glass according to the time at which the first image and the second image are alternatively output by the image providing apparatus.
