Abstract:
Disclosed are an apparatus for transmitting broadcast signals, an apparatus for receiving broadcast signals and methods for transmitting and receiving broadcast signals. The apparatus for transmitting broadcast signals includes a video encoding unit generating a video elementary stream by encoding a video signal, a caption data generation unit generating caption data and caption service information based on a caption signal corresponding to the video signal, a packet generation unit packetizing the video elementary stream, the caption data, and the caption service information such that the caption data is packetized through an independent stream from the video elementary stream, and a transmission unit transmitting the packetized video elementary stream and caption data through a broadcast signal.
Abstract:
The present invention relates to a method and an apparatus for transmitting and receiving an ultra high-definition broadcasting signal for expressing high-quality color in a digital broadcasting system. An apparatus for receiving an ultra high-definition broadcasting signal according to one embodiment of the present invention comprises: a receiving unit for receiving an ultra high-definition broadcasting signal which includes ultra high-definition broadcasting contents and display information metadata representing display environment information suitable for the ultra high-definition broadcasting contents; a decoder for decoding the received ultra high-definition broadcasting contents and the display information metadata; a controlling unit for adjusting the display environment of the receiving apparatus to a display environment suitable for the ultra high-definition broadcasting contents using the display information metadata; and a reproducing unit for reproducing the ultra high-definition broadcasting contents.
Abstract:
A broadcast receiver receives a packetized stream. The broadcast receiver extracts display time information from the header of the received packetized stream, and extracts preparation trigger information including a target service identifier from the payload of the received packetized stream. If a current time is a preparation time designated by the extracted display time information, the broadcast receiver starts to prepare an object corresponding to the target service identifier for activation at a later time.
Abstract:
