Abstract

The present invention provides an apparatus for transmitting a video stream, an apparatus for receiving a video stream, a method for transmitting a video stream, and a method for receiving a video stream. One embodiment of the present invention, discloses the method for transmitting the video stream, comprising the steps of: down-sampling a UHD (ultra high definition) video stream to divide the UHD video stream into a sub-stream of a viewable HD compatible video, a sub-stream of an HD-sized video, and a sub-stream of a residual signal as a difference between the HD compatible video and the HD-sized video, and encoding the divided sub-streams; multiplexing signaling information for describing the relationship between the UHD video stream and at least one sub-stream and including the sub-stream; and transmitting the multiplexed HD sub-stream and the signaling information.

Dependent claims

A method for transmitting a video stream comprising the steps of:

downsampling, by an encoder, a High Efficiency Video (HEVC) stream carrying HEVC-encoded video data by an ultra-high definition (UHD)-to-HD down sampling process and outputting a sub-stream of a high definition (HD) compatible video and a sub-stream of residual data,
wherein the HD compatible video is generated through the UHD-to-HD down sampling process, and
wherein the residual data represents a difference between video data processed through the UHD-to-HD down sampling process and video data decimate-sampled from the HEVC-encoded video data;
encoding, by the encoder, the sub-stream of the HD compatible video and the sub-stream of the residual data, respectively;
multiplexing, by a multiplexer, signaling information describing the sub-streams;
and
transmitting, by a transmitter, the multiplexed sub-streams and the signaling information.
