Data processing unit and data encoding device

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.

1. A data processing unit connected wirelessly to an output device for outputting sensing data and capable of processing the sensing data to be output by the output device, the data processing unit comprising:
a data acquiring section configured to acquire the sensing data to be output by the output device; a first encoding section configured to encode, with a predetermined quality, the sensing data acquired by and received from the data acquiring section to generate first coded data; a radio transmission section configured to transmit the first coded data generated by the first encoding section sequentially to the output device through a radio connection; a second encoding section configured to extract, from the sensing data acquired by and received from the data acquiring section, additional information for increasing the quality of a content included in the first coded data, and encode the additional information to generate second coded data; and a transmission section configured to separately transmit the first coded data and the second coded data to a recording device to record the first coded data and the second coded data on a recording medium, wherein sequential transmission by the radio transmission section of the first coded data is sequential in a temporal manner, and wherein the transmission of the first coded data and the second coded data by the transmission section are separated temporally.
