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.

Providing enhanced video content includes processing at least one video feed through at least one spatiotemporal pattern recognition algorithm that uses machine learning to develop an understanding of a plurality of events and to determine at least one event type for each of the plurality of events. The event type includes an entry in a relationship library detailing a relationship between two visible features. Extracting and indexing a plurality of video cuts from the video feed is performed based on the at least one event type determined by the understanding that corresponds to an event in the plurality of events detectable in the video cuts. Lastly, automatically and under computer control, an enhanced video content data structure is generated using the extracted plurality of video cuts based on the indexing of the extracted plurality of video cuts.

An image processing apparatus includes: a signal receiver configured to receive a content signal comprising video data and first extraction information used in extracting the video data; a signal processor configured to process the video data extracted from the content signal; a communicator comprising communication circuitry configured to communicate with a server; and a controller configured to receive second extraction information from the server through the communication circuitry of the communicator, to extract the video data from the content signal based on the received second extraction information, and to control the signal processor to process an image based on the extracted video data.

The present invention relates to a digital broadcasting system for transmitting/receiving a digital broadcasting signal and a method of processing data. In one aspect of the present invention provides a method of processing data, the method including receiving a broadcasting signal in which mobile service data and main service data are multiplexed, demodulating the received broadcasting signal, obtaining an identifier indicating that data frame of the broadcasting signal includes service guide information, decoding and storing the service guide information from the data frame; and outputting a service included in the mobile service data according to the decoded service guide information.

In a digital contents receiver for receiving transmitted digital contents, the digital contents include at least component information indicating an element which constitutes a program of the contents. When the component information indicates that the received digital contents are a 3D component, it is determined whether a display part corresponds to display of the 3D component. If the display part corresponds to display of the 3D component, the received digital contents are displayed in 3D.

There is provided a method of conveying information using a set of first identifiers, the set of first identifiers having a first number, M, of possible values for representing a first number, M, of first information items. The method comprises the steps of partitioning the set of first identifiers into a second number, N, of sub-partitions, wherein the second number, N, of sub-partitions represents the number of possible values required to represent a set of second information items. A sub-partition is used to transmit a second information item while also transmitting a first information item using a first identifier.

A playback device plays video streams recorded in a recording medium, in which are one or more video streams including at least one of an HDR stream whose dynamic range of luminance of video corresponds to a high dynamic range (HDR), and an SDR stream whose dynamic range of luminance of video corresponds to a standard dynamic range (SDR) narrower than HDR, and identification information indicating whether the HDR stream is included in the one or more video streams. A playback method of the playback device includes: reading the identification information from the recording medium; acquiring playback capability information indicating whether the playback device can play the HDR stream, and display capability information indicating whether a connected display device can display the HDR video; and deciding on a video stream from the one or more video streams, according to the identification information, the playback capability information, and the display capability information.

A method for transmitting broadcast signals in a transmitter. Internet Protocol (IP) packets are input processed to output data of a plurality of Physical Layer Pipes (PLPs). The IP packets include service data for a service and service information for acquiring the service. The service information includes Electronic Service Guide (ESG) signaling information. When an ESG is delivered in a session that is included in at least one of the IP packets, the ESG signaling information includes identification information for identifying the session and IP address and port information for the ESG. Layer 1 (L1) signaling information is encoded for signaling the plurality of PLPs. A first signal frame and a second signal frame are modulated by an Orthogonal Frequency Division Multiplexing (OFDM) method. A first broadcast signal including the modulated first signal frame and a second broadcast signal including the modulated second signal frame are transmitted.
