Abstract

While presenting on a display apparatus videos of high picture quality obtained from portable video processing apparatuses such as a camera and a cellular, it is possible to communicate with the Internet and/or a home network. A display apparatus includes a first radio communication unit capable of receiving video information by radio from an external video processing apparatus, a second radio communication unit capable of connecting by radio to a network, and a control unit for controlling assignment of connection by radio transmission for each of the first and second radio communication units. The control unit assigns connection of the first radio communication unit with higher priority and controls the assignment of the transmission rate such that the transmission rate between the first radio communication unit and the external video processing apparatus is more than that between the second radio communication unit and the network.

Claims

1. A display apparatus, comprising:

a first radio communication unit capable of receiving digital video information by radio from an external video processing apparatus;

a second radio communication unit capable of connecting by radio to the external video processing apparatus, accessing to an internet or a home network through the external video processing apparatus by radio, and receiving digital information; and

a control unit for controlling assignment of connection by radio transmission for each of the first and second radio communication units, so that the first radio communication unit receives digital video information from the external video processing apparatus and the second radio communication unit connects to the internet or the home network simultaneously,

wherein said first radio communication unit and said second radio communication unit are different from each other in frequency bandwidth and modulation/demodulation method,

wherein the control unit controls assignment of a transmission rate between the first radio communication unit and the external video processing apparatus, and assignment of a transmission rate between the second radio communication unit and the internet or the home network, and

wherein the control unit controls the assignment of the transmission rate such that the transmission rate between the first radio communication unit and the external video processing apparatus, is more than the transmission rate between the second radio communication unit and the internet or the home network, when a user issues an indication to receive video information by using the first radio communication unit from the video processing apparatus while acquiring information from the Internet by use of the second radio communication unit.

2. A display apparatus according to claim 1, wherein the control unit assigns connection of the first radio communication unit with higher priority.

3. A display apparatus according to claim 1, further comprising a detection unit for detecting a state of a transmission path, wherein

a demodulation method in the first or second radio communication unit is controlled according to a result of detection conducted by the detection unit.

4. A video processing apparatus, comprising:

a first radio communication unit capable of transmitting digital video information by radio to an external display apparatus;

a second radio communication unit capable of connecting by radio to the external display apparatus, accessing to an internet or a home network, and receiving digital information; and

a control unit for controlling assignment of connection by radio transmission for each of the first and second radio communication units, so that the first radio communication unit transmits digital video information from the external video processing apparatus and the second radio communication unit connects to the internet or the home network simultaneously,

wherein said first radio communication unit and said second radio communication unit are different from each other in frequency bandwidth and modulation/demodulation method,

wherein the control unit controls assignment of a transmission rate between the first radio communication unit and the external video display apparatus, and assignment of a transmission rate between the second radio communication unit and the internet or the home network, and

wherein the control unit controls the assignment of the transmission rate such that the transmission rate between the first radio communication unit and the external video display apparatus, is more than the transmission rate between the second radio communication unit and the internet or the home network, when a user issues an indication to receive video information by using the first radio communication unit from the video processing apparatus while acquiring information from the Internet by use of the second radio communication unit.

5. A video processing apparatus according to claim 4, wherein the control unit assigns connection of the first radio communication unit with higher priority.

6. A video processing apparatus according to claim 4, further comprising a detection unit for detecting a state of a transmission path, wherein

a demodulation method in the first or second radio communication unit is controlled according to a result of detection conducted by the detection unit.
