Abstract

A network apparatus that sends sound data to another network apparatus connected over a network is disclosed. The network apparatus includes: a destination selecting part configured to select a predetermined number of network apparatuses as a destination network apparatus from network apparatuses connected to the network; and a sound data sending part configured to broadcast sound data to the predetermined number of the network apparatuses selected in the destination selecting part.

Claims

1. A network apparatus that sends sound data to another network apparatus connected over a network, the network apparatus comprising:

a destination selecting part configured to select a predetermined number of network apparatuses as a destination network apparatus from network apparatuses connected to the network; and

a sound data sending part configured to broadcast sound data to the predetermined number of the network apparatuses selected in the destination selecting part.

2. The network apparatus according to claim 1, further comprising a network apparatus detecting part configured to automatically detect a network apparatus connected to the network.

3. The network apparatus according to claim 1,

wherein the sound data sending part has:

a shared memory in which the sound data is arranged; and

a sending means for extracting the sound data from the shared memory and for sending the sound data to the corresponding network apparatus, the sending means being provided by the predetermined number.

4. The network apparatus according to claim 1, further comprising a group registration part configured to register a group configured of given network apparatuses selected from network apparatuses connected to the network,

wherein the destination selecting part selects a predetermined number of groups registered in the group registration part to select the predetermined number of the network apparatuses.

5. A sound data transmission method of a network apparatus that sends sound data to another network apparatus connected over a network, the sound data transmission method comprising the steps of:

acquiring sound data from a sound source device;

compressing and encoding sound data acquired in the sound data acquiring step;

arranging sound data compressed and encoded in the compressing and encoding step in a shared memory; and

extracting the sound data from the shared memory and broadcasting the sound data to a predetermined number of the other network apparatuses.

6. A sound data transmission program that allows a computer to function as:

a sound data acquiring means for acquiring sound data from sound source device;

an encoding means for compressing and encoding sound data acquired in the sound data acquiring means;

a sound data arranging means for arranging a sound data compressed and encoded in the encoding means in a shared memory; and

a sound data sending means for extracting the sound data from the shared memory and for broadcasting the sound data to a predetermined number of network apparatuses.

7. A monitoring apparatus that is connected to a security camera having a sound output function over a network, the monitoring apparatus comprising:

a destination selecting means for selecting a predetermined number of the security cameras as a destination from security cameras connected to the network; and

a sound data sending part configured to broadcast sound data to the predetermined number of the security cameras selected in the destination selecting means.

8. A security camera system comprising:

a security camera connected to a monitoring apparatus over a network,

wherein the security camera has;

a sound data receiving part configured to receive sound data sent from the monitoring apparatus; and

a sound output part configured to output sounds configured of sound data received in the sound data receiving part, and

the monitoring apparatus has;

a destination selecting means for selecting a predetermined number of the security cameras as a destination from security cameras connected to the network; and

a sound data sending part configured to broadcast sound data to the predetermined number of the security cameras selected in the destination selecting means.

9. A monitoring apparatus that is connected to a security camera having a sound output function over a network, the monitoring apparatus comprising:

a destination selecting unit configured to select a predetermined number of the security cameras as a destination from security cameras connected to the network; and

a sound data sending part configured to broadcast sound data to the predetermined number of the security cameras selected in the destination selecting unit.

10. A security camera system comprising:

a security camera connected to a monitoring apparatus over a network,

wherein the security camera has;

a sound data receiving part configured to receive sound data sent from the monitoring apparatus; and

a sound output part configured to output sounds configured of sound data received in the sound data receiving part, and

the monitoring apparatus has;

a destination selecting unit configured to select a predetermined number of the security cameras as a destination from security cameras connected to the network; and

a sound data sending part configured to broadcast sound data to the predetermined number of the security cameras selected in the destination selecting means.
