Abstract
A data transmission system, a data transmission method and an electronic equipment. In the playback system, by a controller, at step S1, SEID with respect to receiving stream is grasped. At step S2, inquiry command is used to designate SEID to inquire corresponding Bluetooth output plug No. At step S3, the grasped Bluetooth output plug No. is designated to inquire connecting destination within target of this Bluetooth output plug. Further, in the playback system, by the controller, at step S4, operating state of subunit serving as signal source is inquired. At step S5, information indicating signal source of stream is displayed on a display unit.
Claims54
A data transmission system adapted for carrying out transmission/reception of stream by wireless-connected plural electronic equipments,
- wherein a first electronic equipment which transmits the stream comprises one or plural signal generating means serving as signal source of the stream,
- wherein a second electronic equipment which receives the stream grasps either one of identifier for identifying interface with respect to stream within the first electronic equipment outputted from the one or plural signal generating means and identifier for identifying interface with respect to the stream between the second electronic equipment and the first electronic equipment, and
- wherein the second electronic equipment comprises command generating means for generating command for making an inquiry with respect to the first electronic equipment about mapping of the one identifier which has been grasped and the other identifier which has not been grasped on the basis of the one identifier which has been grasped, and response analysing means for analysing response indicating information of the other identifier transmitted from the first electronic equipment.
A data transmission method of carrying out transmission/reception of stream by wireless-connected plural electronic equipments,
- wherein a second electronic equipment which receives the stream grasps either one of identifier for identifying interface with respect to stream within a first electronic equipment which transmits the stream outputted from one or plural signal generating means serving as signal source of the stream that the first electronic equipment has and identifier for identifying interface with respect to the stream between the first electronic equipment and the second electronic equipment,
- the data transmission method comprising:
- a command generation step of generating command which makes an inquiry with respect to the first electronic equipment about mapping of the one identifier which has been grasped and the other identifier which has not been grasped on the basis of the one identifier that the second electronic equipment has grasped by the second electronic equipment;
- and
- a response analysis step of analysing response indicating information of the other identifier transmitted from the first electronic equipment by the second electronic equipment.
An electronic equipment which is wireless-connected to other electronic equipment and is capable of receiving stream transmitted from the other electronic equipment,
- wherein the electronic equipment grasps either one of identifier for identifying interface with respect to stream within the other electronic equipment outputted from one or plural signal generating means serving as signal source of the stream that the other electronic equipment has and identifier for identifying interface with respect to the stream between the electronic equipment and the other electronic equipment,
- the electronic equipment comprising:
- command generating means for generating command which makes an inquiry with respect to the other electronic equipment about mapping of the one identifier which has been grasped and the other identifier which has not been grasped on the basis of the one identifier which has been grasped;
- and
- response analysing means for analysing response indicating information of the other identifier transmitted from the other electronic equipment.
A data transmission system for carrying out transmission/reception of stream by plural electronic equipments,
- the data transmission system comprising:
- a first electronic equipment for transmitting or receiving the stream;
- a second electronic equipment which is wireless-connected to the first electronic equipment and is capable of receiving or transmitting the stream;
- and
- a third electronic equipment for generating command which selects the second electronic equipment in accordance with the first electronic equipment to instruct the first electronic equipment to connect to the second electronic equipment.
A data transmission method of carrying out transmission/reception of stream by plural electronic equipments,
- the data transmission method comprising:
- a command generation step of generating command which selects, by a third electronic equipment, a second electronic equipment which is wireless-connected to a first electronic equipment for transmitting or receiving the stream and is capable of receiving or transmitting the stream in accordance with the first electronic equipment to instruct the first electronic equipment to connect to the second electronic equipment by the third electronic equipment.
An electronic equipment constituting a data transmission system for carrying out transmission/reception of stream by plural electronic equipments,
- the electronic equipment comprising:

47 The electronic equipment as set forth in claim 46,
- wherein the command generating means generates command which discovers an electronic equipment or equipments in which connection can be made with respect to the first electronic equipment.
48 The electronic equipment as set forth in claim 47,
- wherein the command generating means discovers devices in which connection can be made by the first electronic equipment to list up the devices to select the second electronic equipment from the devices in which connection can be made in accordance with generated response.
49 The electronic equipment as set forth in claim 46,
- wherein the stream is audio stream and/or video stream.
50 The electronic equipment as set forth in claim 46,
- wherein the first electronic equipment and the second electronic equipment are wireless-connected by Bluetooth link, and
- wherein the electronic equipment is wireless-connected to the first electronic equipment by Bluetooth link.
51 The electronic equipment as set forth in claim 46,
- wherein the first electronic equipment and the second electronic equipment are wireless-connected by Bluetooth link, and
