Embodiment approach 1

[0061] figure 1 It is a block diagram showing a schematic configuration example of a data transmission device according to an embodiment of the present invention.

[0062] The data transmission device 10 in this embodiment is composed of a data multiplexing unit 11 and a transmission unit 12 .

[0063] The input video data is compressed and encoded, and output to the data multiplexing unit 11 . Various compression methods such as ISO / IEC 13818-2 (MPEG-2Video), ISO / IEC 14496-2 (MPEG-4 Visual), and ISO / IEC 14496-10 (MPEG-4 AVC) can be used for video encoding.

[0064] Similarly, the input audio data is compressed and encoded, and output to the data multiplexing unit 11 . Various compression methods such as ISO / IEC 13818-7 (MPEG-2 AAC) and ISO / IEC 14496-3 (MPEG-4 Audio) can be used for audio coding.

[0065] Furthermore, the identification information and lighting control data are compressed and coded, and output to the data multiplexing unit 11 . In addition, the identificat...

Embodiment approach 2

[0120] A second embodiment of the present invention will be described with reference to the drawings. Since the schematic structures of the data sending device and the data receiving device in this embodiment are consistent with figure 1 and Figure 7 are the same, so detailed description is omitted.

[0121] First, an example of a lighting device will be described. Figure 14 It is a diagram showing the structure of a table referred to when describing the arrangement pattern of a plurality of lighting devices and the position of each lighting device. The reference table is composed of a first table ( T16 ) indicating the arrangement pattern of the lighting devices in the audio-visual environment space, and a second table ( T16 a , T16 b , T16 c , T16 d ) showing the positions of the lighting devices.

[0122] The data transmission device 10 transmits the value (ChannelTypeID) indicating the lighting arrangement pattern, the value (Position) indicating the position of each ...

Embodiment approach 3

[0135] A third embodiment of the present invention will be described with reference to the drawings. Figure 20 It is a figure which shows another structural example of the table referred to when describing the position of each peripheral device. The reference table is composed of a first table specifying "left", "right", and "front" positions (Position), and a second table specifying a list of available positions and a detailed arrangement of each available position. Figure 20 The definition of Position in the first table is an example, and the positions included in the specific wall surface of the audio-visual environment space may be uniformly defined as surfaces such as "left side", "right side", and "front side". For example, the front left, left, and rear left in the first table can also be collectively defined as the left face, or the front right, right, and rear right in the first table can be collectively defined as the right face.

[0136] The detailed configuratio...
