Abstract

A television reception system is disclosed by which a television broadcasting program can be enjoyed at any place in a home without being influenced by connection to an antenna cable or a communication circuit and which can be connected to a network such as the Internet. A channel selection apparatus and a display apparatus are formed as separate apparatus from each other. The channel selection apparatus receives broadcasting signals, selects one of the broadcasting signals, forms a transmission signal from the selected broadcasting signal and transmits the transmission signal by radio. The radio signal from the channel selection apparatus is received by the display apparatus, and an image based on an image signal of the received signal is displayed on an LCD apparatus serving as a display element.

Claims

1-18. -18. (canceled)

19. A channel selection apparatus capable of receiving television signals, selecting a television signal from the received television signals and transmitting the selected television signal to a physically spaced and separated remote display apparatus, comprising:

a reception unit in communication via a network with the remote display and configured to receive a channel selection instruction from the remote display apparatus;

a channel selection unit configured to select a particular television signal from among supplied television signals in response to the channel selection instruction;

a transmission unit configured to transmit the particular television signal to the remote display apparatus through the network; and

a non-volatile memory configured to store information of the particular television signal selected before power to the channel selection apparatus is interrupted, and to cause said channel selection unit to automatically select a supplied television signal corresponding to the stored information when said power subsequently is restored.

20. The channel selection apparatus according to claim 19, further comprising a compression processing unit configured to compress the particular television signal in accordance with a predetermined compression technique for transmission through said network to said remote display apparatus.

21. The channel selection apparatus according to claim 20, wherein said predetermined compression technique comprises MPEG (Motion Picture Expert Group) processing.

22. The channel selection apparatus according to claim 19, wherein

said transmission unit modulates the particular television signal and transmits the modulated television signal to the remote display apparatus;

and wherein said network is a wireless communication channel.

23. A channel selection method capable of receiving television signals, selecting a television signal from the received television signals and transmitting the selected television signal over a network to a remote display apparatus, comprising the steps of:

receiving a channel selection instruction over said network from said remote display apparatus;

selecting a particular television signal from among the received television signals in response to the channel selection instruction;

storing information of the particular television signal in a non-volatile memory;

transmitting the particular television signal to the remote display apparatus through the network; and

automatically re-selecting a received television signal corresponding to the information stored in said non-volatile memory immediately prior to an interruption in power at the time said power is restored.

24. A program embodied in a computer-readable medium to control a processor to implement a channel selection method capable of receiving television signals, selecting a television signal from the received television signals and transmitting the selected television signal over a network to a remote display apparatus, said program consisting of instructions to control said processor to perform the method comprising the steps of:

receiving a channel selection instruction over said network from said remote display apparatus;

selecting a particular television signal from among the received television signals in response to the channel selection instruction;

storing information of the particular television signal in a non-volatile memory;

transmitting the particular television signal to the remote display apparatus through the network; and

automatically re-selecting a received television signal corresponding to the information stored in said non-volatile memory immediately prior to an interruption in power at the time said power is restored.

25. A computer-readable record medium on which is stored computer-readable instructions to control a processor to carry out the method by which a television signal is selected from received television signals and transmitted over a network to a remote display apparatus, said method implemented by said instructions comprising the steps of:

receiving a channel selection instruction over said network from said remote display apparatus;

selecting a particular television signal from among the received television signals in response to the channel selection instruction;

storing information of the particular television signal in a non-volatile memory;

transmitting the particular television signal to the remote display apparatus through the network; and

automatically re-selecting a received television signal corresponding to the information stored in said non-volatile memory immediately prior to an interruption in power at the time said power is restored.
