DIGITAL BROADCASTING SYSTEM AND METHOD OF PROCESSING DATA IN DIGITAL BROADCASTING SYSTEM

摘要

The present invention
provides a method of processing
data in digital broadcasting system.
The method includes receiving a
broadcast signal including mobile
broadcast service data and main
broadcast service data, wherein
the mobile broadcast service data
configures a RS frame, and wherein
the RS frame includes at least one
data packet corresponding to the
mobile broadcast service data, an
RS parity generated based upon the
at least one data packet, and a CRC
checksum generated based upon the
at least one data packet and the RS
parity, performing CRC-decoding
and RS-decoding on the RS frame,
thereby correcting errors occurred in
the corresponding mobile broadcast
service data, extracting video data
from the mobile broadcast service data
and decoding the extracted video data,
wherein the video data includes data
of a base layer and data of an enhanced
layer and wherein the enhanced layer
has a spatial resolution or an image
quality different from that of the base
layer.
