Abstract
According to one embodiment, an encoding apparatus encodes each of items of image data captured in the same space by a plurality of cameras. A streaming apparatus changes items of encoded image data into streams, respectively. A resolution setting apparatus determines a resolution of each item of image data within the streams. A stream selection apparatus selects one or more streams from a plurality of streams within a transmission capacity. A stream synthesis apparatus synthesizes a selected stream and a stream which carries a control signal into one stream, and outputs a synthesized stream.
Claims13
A transmission signal processing apparatus comprising:
- an encoding apparatus which encodes each of items of captured image data captured in a same shooting space by a plurality of cameras provided at different locations;
- a resolution setting apparatus which operates together with the encoding apparatus, and sets respective resolutions of image data;
- a streaming apparatus which changes items of encoded image data into streams, respectively, the items of encoded image data being those for which the resolutions are set and which are encoded in accordance with the items of captured image data;
- a stream selection apparatus which selects one or more streams from a plurality of streams which carry the encoded image data;
- a stream synthesis apparatus which synthesizes a selected stream and a stream which carries a control signal into one stream, and outputs a synthesized stream;
- and
- a transmission signal generation apparatus which outputs the synthesized stream as a transmission signal.
A received signal processing apparatus comprising:
- a reception/demodulation device which receives and demodulates a synthesized stream produced by synthesizing a first stream which carries first image data for which a first resolution is set and which is encoded, and a second stream which carries second image data for which the first resolution or a second resolution is set and which is encoded, the first image data and the second image data being items of image data which are acquired by imaging a subject in a same shooting space from different angles;
- a separation circuit which separates the first stream from the second stream;
- first and second decoders which decode items of image data of the separated first and second streams, and obtain the first image data and the second image data;
- a display pattern setting module for outputting the first and second image data to a display such that first and second images produced by the first and second image data are arranged in a display area of the display in a set display pattern;
- and
- a system control apparatus which communicates with a portable monitor in order to select the display pattern from a plurality of patterns, receives an operation signal, and controls the display pattern setting module.
A method of processing a transmission signal in a block which forms a transmission apparatus, the method comprising:
- encoding each of items of captured image data captured in a same shooting space by a plurality of cameras provided at different locations;
- determining respective resolutions of image data;
- changing items of encoded image data for which the resolutions are set and which are encoded into streams, respectively;
- selecting one or more streams from a plurality of streams which carry the encoded image data;
- synthesizing a selected stream and a stream which carries a control signal into one stream, and outputting a synthesized stream;
- and
- outputting the synthesized stream as a transmission signal.
