Abstract
A data communication apparatus and method that permits communication between two devices without having to perform a complicated initial connection procedure. A communication unit conducts data transmission/reception with an external data communication apparatus, and a controller controls the communication unit to operate in one of a network mode or a broadcast mode. The network mode conducts network communication via connection through an initial connection procedure with the external data communication apparatus and the broadcast mode receives or transmits data to/from the external data communication apparatus according to a predetermined broadcast method.
Claims20
A data communication apparatus comprising:
- a communication unit conducting data transmission/reception with an external data communication apparatus;
- and
- a controller controlling the communication unit to operate in one of a network mode and a broadcast mode,
- wherein the network mode conducts network communication via connection through an initial connection procedure between the external data communication apparatus and the data communication apparatus, in which said initial connection procedure includes a search, selection and acceptance of a communication session prior to the transmission or reception of data, and
- wherein the broadcast mode transmits data to the external data communication apparatus or receives data from the external data communication apparatus according to a predetermined broadcast method without said initial connection procedure between the external data communication apparatus and the data communication apparatus.
A data communication apparatus comprising:
- a communication unit conducting data transmission/reception with an external data communication apparatus;
- and
- a controller controlling the communication unit to operate in one of a network mode and a broadcast mode,
- wherein the network mode conducts network communication via connection through an initial connection procedure with the external data communication apparatus,
- wherein the broadcast mode transmits data to the external data communication apparatus or receives data from the external data communication apparatus according to a predetermined broadcast method, and
- wherein the controller controls the communication unit to operate in one of the network mode and the broadcast mode according to a type of data to be transmitted.
A data communication apparatus comprising:
- a communication unit conducting data transmission/reception with an external data communication apparatus;
- and
- a controller controlling the communication unit to operate in one of a network mode and a broadcast mode,
- wherein the network mode conducts network communication via connection through an initial connection procedure with the external data communication apparatus, and
- wherein the broadcast mode transmits data to the external data communication apparatus or receives data from the external data communication apparatus according to a predetermined broadcast method, and
- wherein the controller controls the communication unit to operate in one of the network mode and the broadcast mode according to a number of external communication devices that are to be transmitted a same data.
A data communication method of a data communication apparatus comprising:
- determining by a controller a selection of one of a network mode and a broadcast mode for communication;
- and
- conducting by a communication unit network communication via connection through an initial connection procedure with an external data communication apparatus when the network mode is determined, in which said initial connection procedure includes a search, selection and acceptance of a communication session between the data communication apparatus and the external data communication apparatus prior to a transmission or reception of data, and transmitting or receiving a data to or from the external data communication apparatus in a broadcast method when the broadcast mode is determined,
- wherein the controller controls the communication unit to operate in one of the network mode and the broadcast mode according to a type of data to be transmitted.
A data communication method of a data communication apparatus comprising:
- determining a selection of one of a network mode and a broadcast mode for communication;
- and
- conducting network communication via connection through an initial connection procedure with an external data communication apparatus when the network mode is determined, and transmitting data to the external data communication apparatus or receiving data from the external data communication apparatus in a broadcast method when the broadcast mode is determined, wherein the selection of one of the network mode and the broadcast mode is based on at least one of a size of the data to be transmitted and a number of external communication devices that are to be transmitted a same data.
