The present technology relates to a receiving device, a receiving method, a transmitting device, and a transmitting method that enable a more appropriate introduction of a new broadcasting scheme.

A receiving device is provided including a receiving unit that receives a transmission frame transmitted from a transmitting device, and a demodulation unit that performs demodulation processing on a data signal obtained from a transmission frame that has been received, on the basis of a transmission control signal obtained from the transmission frame that has been received, in which the transmission control signal includes time-division control information regarding time-division control, as control information according to introduction of a second scheme compatible with a first scheme, and the demodulation unit operates according to the time-division control information. The present technology can be applied to, for example, a transmission system compliant with a broadcasting scheme such as an ISDB-T scheme.

A method for receiving a device capability associated with a service guide is described. The method may include (a) receiving a content fragment within said service guide; (b) receiving capabilities syntax element within said content fragment that indicates required capabilities for decoding and presenting signaled content; (c) wherein said capabilities syntax element includes: (i) an element capability code (ccode) that represents a certain capability or capability group defined by 1 to 4 hexadecimal digits (1*4HEXDIG); (ii) an element capability string code (capability_string_code) having a first operand (ubyte) that represents a registry identified by capability category code and a second operand (1*utf8) that specifies a capability or capability group within said registry, where said first operand (ubyte) is defined as 1 to 3 digits (1*3DIGIT) and said utf8 is defined as one or more UTF-8 characters (*(UTF8-char)); (d) decoding said service guide.

The reception side can easily acquire at least function enhancement information inside a codec. Image data of each picture of a base layer is encoded to generate a first encoded stream, and image data of each picture of an enhanced layer is encoded to generate a second encoded stream. The first encoded stream and the second encoded stream are transmitted. Function enhancement information including at least function enhancement information inside a codec is transmitted outside the encoded stream. For example, the function enhancement information further includes function enhancement information outside the codec.

A system and method for automatically recording viewer reactions to viewed video content. The system and method utilize a system that responds to pre-tagged segments of video content. Upon recognition of such a tagged segment, a video camera is activated to capture the viewer response. A composite video of the captured viewer response and the segment of viewed video is then created. The viewer is notified that the composite video has been created. The system and method also provide the viewer with options to share the video via social media.

This technique relates to a receiving device, a receiving method, a providing device, a providing method, a program and a broadcasting system that can notify the receiving side of control information such as the timing to synchronize an application program with progress of a show without using a television broadcast signal. When the application control type written in the application control descriptor is 3, the receiving device acquires application control data from a server, and, for example, acquires and starts a new information service application in accordance with the segment data forming the application control data. When an external device is designated as the command destination device, the receiving device generates a command for the external device, and outputs the command to the external device. In accordance with the command from the receiving device, the external device, for example, acquires and starts the new information service application. This disclosure can be applied in a case where the receiving device is controlled from the broadcasting side.

Apparatus and methods conforming to the present invention comprise a method of controlling playback of an audio signal through analysis of a corresponding close caption signal in conjunction with analysis of the corresponding audio signal. Objection text or other specified text in the close caption signal is identified through comparison with user identified objectionable text. Upon identification of the objectionable text, the audio signal is analyzed to identify the audio portion corresponding to the objectionable text. Upon identification of the audio portion, the audio signal may be controlled to mute the audible objectionable text.
