Abstract

An electronic apparatus executes communication with an external device. The electronic apparatus includes an encoder that encodes source data to generate transmission data, a communication device that transmits the transmission data generated by the encoder to the external device, a unit that determines the quality with which the source data is to be transmitted, in accordance with the type of the source data, and a unit that controls the encoder to vary an amount of the generated transmission data on the basis of the determined quality.

Claims

1. An electronic apparatus comprising:

an encoder that encodes source data to generate transmission data;

a wireless communication device that executes communication with an external device via a wireless network, and transmits the transmission data generated by the encoder to the external device;

means for detecting the number of devices connected to the wireless communication device via the wireless network;

means for determining a rate at which the source data is to be transmitted, on the basis of the detected number of devices and a type of the source data, wherein when the detected number is greater than a preset value, the rate is determined lower than when the detected number is not greater than the preset value; and

means for controlling the encoder to vary an amount of the generated transmission data on the basis of the determined rate of the source data.

2. The electronic apparatus according to claim 1, wherein the controlling means includes means for setting in the encoder a value of sampling frequency, which is to be used in the encoding of the source data, in accordance with the determined rate of the source data.

3. The electronic apparatus according to claim 1, wherein the controlling means includes means for setting in the encoder a kind of an encoding scheme, which is to be used in the encoding of the source data, in accordance with the determined rate of the source data.

4. The electronic apparatus according to claim 1, wherein the controlling means includes means for setting in the encoder a kind of an encoding scheme, which is to be used in the encoding of the source data, and a value of sampling frequency, which is to be used in the encoding of the source data, in accordance with the determined rate of the source data.

5. The electronic apparatus according to claim 1, further comprising a plurality of input devices capable of inputting data,

wherein the rate determining means includes means for detecting the type of the source data by determining from which of the input devices the source data is input.

6. The electronic apparatus according to claim 1, wherein:

the source data includes audio data,

the electronic apparatus further includes means for determining whether a device that transmits image data is connected to the wireless communication device via the wireless network, and

the rate determining means includes means for setting, when the device that transmits image data is connected to the wireless communication device, the rate of the source data at a first rate which is lower than a given rate.

7. A program that is stored in a computer-readable medium and controls wireless communication for transmitting transmission data, which is generated by encoding source data, from a computer to an external device via a wireless network, comprising:
