Image display apparatus, image transmitting apparatus, image transmitting method and recording medium

An image display apparatus, comprising:

• a signal transceiver configured to transmit a signal requesting a bit stream for reproducing a moving image at an arbitrary multiple speed, and to receive the bit stream for reproducing a moving image at an arbitrary multiple speed;
• and
• a controller configured to reproduce the moving image at an arbitrary multiple speed through an image output unit,
• wherein the bit stream for reproducing a moving image at the arbitrary multiple speed is generated using first moving image data for multiple speed reproduction separately generated from second moving image data for normal speed reproduction, the first moving image data constructed using I-frames selected from a plurality of group of pictures (GOPs) included in the second moving image data.

An image transmitting method, comprising:

• storing first moving image data for multiple speed reproduction separately generated from second moving image data for normal speed reproduction, the first moving image data being generated using I-frames selected from a plurality of group of pictures (GOPs) included in the second moving image data;
• receiving a signal requesting a bit stream for reproducing a moving image at an arbitrary multiple speed;
• and
• transmitting the bit stream for reproducing the moving image at the arbitrary multiple speed according to the signal.
