The present invention provides a method and an apparatus for transmitting and receiving a broadcast signal so as to adjust a colour range of content. The method for transmitting a broadcast signal according to an embodiment of the present invention comprises the steps of: encoding video data and signalling information including metadata with respect to the gamut of the video data; generating a broadcast signal including the encoded video data and signalling information; and transmitting the generated broadcast signal.

The present invention provides a method and an apparatus for transceiving a broadcast signal for viewing environment adjustment. A method for transmitting a broadcast signal, in accordance with one embodiment of the present invention, comprises the steps of: encoding video data and signaling information including metadata regarding the production environment of the video data; generating a broadcast signal comprising the encoded video data and signaling information; and transmitting the generated broadcast signal.

A tactile vibration signals is satisfactorily transmitted. A transmission signal for each block including a plurality of frames for an audio signal is sequentially transmitted to a receiving side via a predetermined transmission line. The transmission signal includes a tactile vibration signal of a predetermined number of channels. For example, the tactile vibration signal is generated on the basis of a media signal associated with the audio signal. For example, configuration information of the tactile vibration signal of the predetermined number of channels is added to the transmission signal. For example, the configuration information is added by use of a predetermined bit area of a channel status configured for each block.
