    摘要： Disclosed in a technique for performing data transmission between units efficiently in an imaging device, in which a camera unit and the other units (particularly a display unit) are separated and connected wirelessly, to improve convenience. According to this technique, video content data imaged by an imaging section is encoded, by means of hierarchical coding, into checking content coded data of a core layer and saving content coded data of an enhancement layer. The checking content coded data is sent immediately from a checking content transmission section 906 to a display unit 950 through wireless communication, and a display thereof is output. On the other hand, the saving content coded data is stored in a recording section 907 together with the checking content coded data. Thus, both a rapid display of video content data and storage thereof while keeping the quality are achieved.
