Abstract
The present invention relates to a device and method for transmitting and receiving a broadcasting signal including a subtitle service. An embodiment of the present invention provides a broadcasting signal transmission method comprising the steps of: generating a broadcasting signal including video data and subtitle data; and transmitting the generated broadcasting signal. According to an embodiment of the present invention, a transmission stream providing a digital broadcasting subtitle service using XML subtitles can be transmitted.
Claims15
1-14. (canceled)
A method of transmitting a broadcast signal, comprising:
- encoding, by an encoder, High Efficiency Video Coding (HEVC) video data including a Supplemental Enhancement Information (SEI) message for video quality enhancement;
- generating, by a multiplexer, a broadcast signal including the encoded HEVC video data;
- and
- transmitting, by a transmitter, the generated broadcast signal,
- wherein the SEI message for video quality enhancement includes luminance information being applicable to the encoded HEVC video data.
A method of receiving a broadcast signal, comprising:
- receiving a broadcast signal including High Efficiency Video Coding (HEVC) video data with a supplemental enhancement information (SEI) message for video quality enhancement;
- demultiplexing the broadcast signal into the HEVC video data and the SEI message for the video quality enhancement;
- decoding the HEVC video data and the SEI message for the video quality enhancement;
- and
- applying luminance information included in the SEI message for the video quality enhancement to the decoded HEVC video data.
A broadcast signal transmission device comprising:
- an encoder to encode High Efficiency Video Coding (HEVC) video data including a Supplemental Enhancement Information (SEI) message for video quality enhancement;
- a multiplexer to generate a broadcast signal including the encoded HEVC video data;
- and
- a transmitter to transmit the generated broadcast signal,
- wherein the SEI message for video quality enhancement includes luminance information being applicable to the encoded HEVC video data.
A broadcast signal reception device comprising:
- a receiver to receive a broadcast signal including High Efficiency Video Coding (HEVC) video data with a supplemental enhancement information (SEI) message for video quality enhancement;
- a demultiplexer to demultiplex the broadcast signal into the HEVC video data and the SEI message for the video quality enhancement;
- a decoder to decode the HEVC video data and the SEI message for the video quality enhancement;
- and
- a post processor to apply luminance information included in the SEI message for the video quality enhancement to the decoded HEVC video data.
