Abstract

In a television receiver, based on speaker information of each of one or more devices including speakers which is a memory of the television receiver, a transmitting audio signal to be transmitted to each device including a speaker, in which synchronization is established between devices including speakers in a reproduction mode, is formed and transmitted to the device (including a speaker) through a communication interface. The device (including a speaker) receives the transmitting audio signal addressed thereto through a communication interface, plays back the signal, and uses a speaker of the device to generate sound.

Claims

1. A transmitting/receiving system comprising:

a transmitting device for transmitting an audio signal; and

at least one device including a speaker and having a function of operating in stand-alone form,

wherein;

said transmitting device comprises;

storage means for storing speaker information of said at least one device for each of said at least one device;

forming means for forming, based on the speaker information stored in said storage means, from an audio signal being subject to processing, a transmitting audio signal to be transmitted to each of said at least one device; and

transmitting means for transmitting the transmitting audio signal formed by said forming means to each of said at least one device; and

each of said at least one device comprises;

receiving means for receiving the transmitting audio signal transmitted from said transmitting device, the transmitting audio signal being addressed to each of said at least one device; and

generating means for generating, from the transmitting audio signal received by said receiving means, an audio signal to be supplied to each speaker included in each of said at least one device.

2. The transmitting/receiving system according to claim 1, wherein said transmitting device further comprises:

accepting means for accepting an input for setting the speaker information; and

recording means for recording, in said storage means, the speaker information accepted by said accepting means.

3. The transmitting/receiving system according to claim 1, wherein:

said transmitting device further comprises;

receiving means for receiving the speaker information transmitted from said at least one device; and

recording means for recording, in said storage means, the speaker information received by said receiving means; and

each of said at least one device further comprises;

information storing means for storing speaker information of each of said at least one device; and

transmitting means for transmitting the speaker information stored in said information storing means to said transmitting device.

4. The transmitting/receiving system according to claim 1, wherein the speaker information stored in said storage means of said transmitting device includes at least one of a speaker frequency characteristic, a maximum volume level, the time required for output after receiving the audio signal, the number of speakers, and positional information of said at least one device.

5. The transmitting/receiving system according to claim 3, wherein said transmitting device further comprises accepting means for accepting, as a piece of the speaker information stored in said storage means, an input for setting positional information of said at least one device.

6. A transmitting device for transmitting an audio signal to each of at least one device including a speaker, said transmitting device comprising:

storage means for storing speaker information of said at least one device for each of said at least one device;

forming means for forming, based on the speaker information stored in said storage means, from an audio signal being subject to processing, a transmitting audio signal to be transmitted to each of at least one device; and

transmitting means for transmitting the transmitting audio signal formed by said forming means to each of said at least one device.

7. The transmitting device according to claim 6, further comprising:

accepting means for accepting an input for setting the speaker information; and

recording means for recording, in said storage means, the speaker information accepted by said accepting means.

8. The transmitting device according to claim 6, further comprising:

receiving means for receiving the speaker information transmitted from said at least one device; and

recording means for recording, in said storage means, the speaker information received by said receiving means.

9. The transmitting device according to claim 6, wherein the speaker information stored in said storage means includes at least one of a speaker frequency characteristic, a maximum volume level, the time required for output after receiving the audio signal, the number of speakers, and positional information of said at least one device.

10. The transmitting device according to claim 8, further comprising:

accepting means for accepting, as a piece of the speaker information stored in said storage means, an input for setting positional information of said at least one device; and

recording means for recording, in said storage means, the speaker information accepted by said accepting means.

11. A device including a speaker and having a function of operating in stand-alone form, said device comprising:

receiving means for receiving a transmitting audio signal transmitted and addressed to said device; and

generating means for generating, from the transmitting audio signal received by said receiving means, an audio signal to be supplied to the speaker included in said device.

12. The device according to claim 11, further comprising:

information storing means for storing speaker information of said device; and

transmitting means for transmitting the speaker information stored in said information storing means to a transmitting device transmitting the transmitting audio signal.

13. The device according to claim 12, wherein the speaker information stored in storage means included in the said transmitting device includes at least one of a speaker frequency characteristic, a maximum volume level, the time required for output after receiving the audio signal, the number of speakers, and positional information of said device.
