METHOD AND SYSTEM FOR PROVIDING HIGH DEFINITION (HD) BROADCASTING SERVICE AND ULTRA HIGH DEFINITION (UHD) BROADCASTING SERVICE

摘要

A method of transmitting a high definition (HD) image and an ultra high definition (UHD) image, the method including obtaining a first HD image by down-scaling an original UHD image, obtaining at least one of a second HD image and a half-resolution UHD image by down-scaling the original UHD image, encoding the first HD image, encoding at least one of the second HD image and the half-resolution UHD image, generating a first transmission stream by multiplexing and synchronizing the encoded first HD image, generating a second transmission stream by multiplexing and synchronizing at least one of the encoded second HD image and the encoded half-resolution UHD image, transmitting the first transmission stream via a first transmission channel, and transmitting the second transmission stream via a second transmission channel differing from the first transmission channel is provided.

1. A method of transmitting a high definition (HD) image and an ultra high definition (UHD) image, the method comprising:
obtaining a first HD image by down-scaling an original UHD image; obtaining at least one of a second HD image and a half-resolution UHD image by down-scaling the original UHD image; encoding the first HD image; encoding at least one of the second HD image and the half-resolution UHD image; generating a first transmission stream by multiplexing and synchronizing the encoded first HD image; generating a second transmission stream by multiplexing and synchronizing at least one of the encoded second HD image and the encoded half-resolution UHD image; transmitting the first transmission stream via a first transmission channel; and transmitting the second transmission stream via a second transmission channel differing from the first transmission channel.
