Abstract

In a provided information processing device, a first information processing module, within its transmission time segment, transmits an encoded signal in which mutually distinct first and second bit values are respectively expressed by pluralities of mutually distinct first amplitude values and second amplitude values, the same amplitude value not occurring consecutively and the amplitude value polarity being inverted with each cycle. Within a transmission time segment for a second information processing module, the first information processing module transmits a clock signal that corresponds to the cycle at which the polarity is inverted. The second information processing module extracts the clock signal by detecting the polarity inversions in the encoded signal, decodes the first and second bit values from the encoded signal using the clock signal, generates a transmission signal by controlling the amplitude values of the clock signal, and transmits the transmission signal in synchronization with the clock signal.

Description

technical field [0001] The present invention relates to an information processing device and a two-way transmission method. Background technique [0002] Most mobile terminals represented by mobile phones and the like use a movable member as a connecting portion between an operating portion operated by a user and a display portion displaying information. Typical examples include opening and closing structures of folding mobile phones and the like. In addition, recent mobile phones have a video viewing function, a camera function, etc. that require moving the above-mentioned connection parts in a complex manner according to the user's usage, in addition to the telephone function and the e-mail function. For example, in the case where a mobile phone is used for viewing and listening to videos, it is conceivable that the user should turn the display portion toward himself, and put away operation portions that are unnecessary for viewing and listening. Therefore, there is a ne...
