Abstract

A transmitting device is provided with a TV tuner for receiving television broadcasts, a DVD player for reading out data from a DVD medium, etc. Based on the wireless communications between the transmitting device and the user'"'"'s small terminal carried by the user, the ID of a receiving device that is located in the neighborhood of the user is acquired. The transmitting device 1 transfers a variety kinds of data, including television broadcast data received by the TV tuner and the DVD data read out by the DVD player, to the recognized receiving device identified by the ID received from the user'"'"'s small terminal.

Claims

1. A data transmitting/receiving system comprising:

a transmitting device configured to transmit data; and

a plurality of receiving devices configured to receive data from the transmitting device,

the transmitting device including;

a recognizing unit configured to recognize which one of the receiving devices is located in a neighboring region of a predetermined user; and

a data transmission-controlling unit configured to transmit data to the receiving device recognized by the recognizing unit.

2. The data transmitting/receiving system according to claim 1, wherein the transmitting device and the receiving device exchange data by wireless communications.

3. The data transmitting/receiving system according to claim 1, wherein the transmitting device further includes a managing unit configured to manage a data reproduction function provided for each of the receiving devices,

the data transmission-controlling unit prepares transmission data in accordance with the data reproduction function of each receiving device managed by the managing unit.

4. The data transmitting/receiving system according to claim 1, further comprising:

a small terminal device including a detection unit configured to detect which one of the receiving devices is located within a predetermined region, and a notification unit configure to notify the transmitting device of identification data on the receiving device detected by the detection unit,

the recognizing unit of the transmitting device recognizes which one of the receiving devices can receive data, on the basis of the identification data sent from the notification unit of the small terminal device.

5. The data transmitting/receiving device according to claim 4, wherein the detection unit of the small terminal device detects a receiving device based on wireless communications, and acquires identification data from the detected receiving device.

6. The data transmitting/receiving device according to claim 4, wherein, when the detection unit of the small terminal device newly detects another receiving device different from any one of the receiving devices, the notification unit of the small terminal device notifies the transmitting device of identification data on the another receiving device.

7. The data transmitting/receiving device according to claim 4, wherein the detection unit of the small terminal device detects that the receiving device detected last time moves out of the predetermined region,

the notification unit of the small terminal device notifies the transmitting device of a time when the detection unit of the small terminal device detects that the receiving device detected last time moves out of the predetermined region.

8. The data transmitting/receiving device according to claim 4, wherein the data transmission-controlling unit of the transmitting device operates such that when data must be transmitted to a given user and if the recognizing unit of the transmitting device recognizes none of the receiving devices, the data transmission-controlling unit transmits data to the small terminal device, thereby notifying the user that data to be transmitted is present.

9. The data transmitting/receiving device according to claim 8, wherein the transmitting device further includes a determination unit configured to determine priority of each data,

recognizing which one of the receiving devices is located in a neighboring region of a predetermined user; and

transmitting data to a receiving device that has been recognized.

14. The data transmitting/receiving method according to claim 13, wherein the transmitting step prepares the data transmitted to each receiving device in accordance with a data reproduction function of each receiving device.

15. The data transmitting/receiving method according to claim 13, wherein the recognizing step recognizing one of the receiving devices that is capable of receiving data, based on identification data sent by a small terminal device, the small terminal device including a detection unit configured to detect which one of the receiving devices is located within a predetermined region, and a notification unit configured to notify the transmitting device of identification data on the receiving device detected by the detection unit.

16. The data transmitting/receiving method according to claim 15, wherein the transmitting step transmits to the small terminal device data which notifies a given user that there is data to be transmitted, when the data must be transmitted to the given user and if none of the receiving devices is recognized.

17. The data transmitting/receiving method according to claim 16, further comprising:

determining priority of each data,

the transmitting step transmits data to the small terminal device only when the priority of the data is determined to be higher than a preset level.
