Abstract: A metadata preparing device comprising a content reproducing unit (1) for reproducing and outputting content, a monitor (3) for monitoring the content reproduced by the content reproducing unit, a voice input unit (4), a voice recognition unit (5) for recognizing a voice signal input from the voice input unit, a metadata generation unit (6) for converting information recognized by the voice recognition unit into metadata, and an identification information imparting unit (7) for acquiring identification information that identifies respective parts in the content from the reproduced content supplied from the content reproducing unit, for imparting to metadata, wherein the generated metadata is so constructed as to be associated with respective parts in the content.

Abstract: A first moving image information volume compression encoder which compression-encodes a video signal from a camera part as a moving image, a second still image information volume compression encoder which compression-encodes the input video signal as a still image, and recording means which records, in memory means, both a first compression signal obtained by the first compression encoder and a second compression signal obtained by the second compression encoder. The compression encoders shoot based on shutters respectively which are independent of each other.
