Abstract

An information processing apparatus includes: position detection means for detecting a position of a client unit held by a user on the basis of a signal outputted from the client unit; conversion means for variably setting a parameter value used to convert at least one of a sound signal and a video signal on the basis of the position of the client unit detected by the position detection means and converting the signal using the parameter value; and output means for outputting the signal after conversion by the conversion means.

Claims

1. An information processing apparatus comprising:

position detection means for detecting a position of a client unit held by a user on the basis of a signal outputted from the client unit;

conversion means for variably setting a parameter value used to convert at least one of a sound signal and a video signal on the basis of the position of the client unit detected by the position detection means and converting the signal using the parameter value; and

output means for outputting the signal after conversion by the conversion means.

2. The information processing apparatus according to claim 1,

wherein the conversion means variably sets a parameter value used to determine a mixing ratio of a multi-channel sound signal and converts the sound signal using the parameter value.

3. The information processing apparatus according to claim 1,

wherein, of a plurality of divided regions obtained by dividing a predetermined region, the position detection means detects information specifying a divided region in which the client unit is positioned, and

the conversion means variably sets the parameter value on the basis of the information detected by the position detection means.

4. The information processing apparatus according to claim 1,

wherein the conversion means variably sets a parameter value used to determine an enlargement ratio of one of a video corresponding to the video signal and a character relating to the video and converts the video signal using the parameter value.

5. The information processing apparatus according to claim 1,

the position detection means detects the position of the client unit as a time variable on the basis of temporal transition of a signal outputted from the client unit.

6. The information processing apparatus according to claim 1,

wherein the conversion means maintains setting of the parameter value in a case where the position detection means detects that the position of the client unit has not been changed.

7. An information processing method for an information processing apparatus that outputs at least one of a sound signal and a video signal as an output signal, the method comprising the steps of:

detecting a position of a client unit held by a user on the basis of a signal outputted from the client unit;

variably setting a parameter value used to convert an original signal from which the output signal is generated on the basis of the detected position of the client unit and converting the signal using the parameter value; and

outputting the signal after conversion as the output signal.

8. A computer-readable medium storing a program causing a computer that performs control to output at least one of a sound signal and a video signal as an output signal to perform control processing comprising the steps of:

detecting a position of a client unit held by a user on the basis of a signal outputted from the client unit;

variably setting a parameter value used to convert an original signal from which the output signal is generated on the basis of the detected position of the client unit and converting the signal using the parameter value; and

outputting the signal after conversion as the output signal.

9. An information processing apparatus comprising:

a position detection unit configured to detect a position of a client unit held by a user on the basis of a signal outputted from the client unit;

a conversion unit configured to variably set a parameter value used to convert at least one of a sound signal and a video signal on the basis of the position of the client unit detected by the position detection unit and convert the signal using the parameter value; and

an output unit configured to output the signal after conversion by the conversion unit.
