Claim Text:
1. A method of providing a realistic broadcasting image including an ultra high definition (UHD) image, the method comprising: generating a first encoding stream from a high definition (HD) image; generating a second encoding stream from a UHD image and an image restored from the first encoding stream; generating a decoded image by decoding the first or second encoding stream; obtaining a restored UHD image, differing from the UHD image, by expanding a resolution of the decoded image and converting a scanning method when a scanning method of the decoded image is different from a scanning method of the UHD image; generating a third encoding stream from the UHD image and an image restored from the second encoding stream; generating a first transmission stream by applying at least one of packetization, synchronization, and multiplexing to the first encoding stream and the second encoding stream; generating a second transmission stream by applying at least one of packetization and synchronization to the third encoding stream; transmitting the first transmission stream via a first transmission channel; and transmitting the second transmission stream via a second transmission channel having a lower transmission capacity than the first transmission channel.
