Title:
SIGNAL TRANSMISSION DEVICE, SIGNAL TRANSMISSION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/169887
Kind Code:
A1
Abstract:
The present disclosure relates to a signal transmission device, signal transmission method, and program, which are capable of alleviating an impact caused by a quantization error. A quantization error notification unit notifies a stage which is downstream of a bit precision restriction region, which is a region in which a restriction of bit precision occurs, of a quantization error which occurs in a quantization processing unit which carries out a quantization process upon a signal which is transmitted via the bit precision restriction region. A quantization error receiving unit receives the quantization error and supplies the quantization error to an inverse quantization processing unit which carries out an inverse quantization process upon the signal which is transmitted via the bit precision restriction region. It would be possible, as an example, to apply the present technology to an image signal transmission device which transmits an image signal.
