(Embodiment)
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a television receiving system according to the first embodiment of the present invention. In FIG. 1, 101 is a portable television receiver, and 102 is a stationary television receiver. The portable television receiver 101 is a television receiver that can be easily held by a viewer or moved by hand. The stationary television receiver 102 is a large television receiver installed in a living room of a home, and is generally installed and used without being moved on a daily basis.

  The antenna 1 receives radio waves of television broadcasting. The channel selection unit 2 selects a television signal of a program from the RF signal by a viewer operation or the like. The demodulator 3 demodulates the video signal, audio signal, and information data. The control unit 4 controls each unit of the mobile television receiver 101. The storage unit 5 stores data such as channel information during channel selection. The display unit 6 displays the demodulated video signal. The speaker 7 outputs an audio signal. The operation unit 8 is an input means for the viewer to perform operations such as channel selection, and includes a power switch and a channel up / down key for selecting and viewing a desired program. An infrared transmission unit 9 as a transmission unit that outputs a remote control signal outputs channel information and the like as a remote control signal. The vibration sensor 10 detects vibration generated when the portable television receiver 101 moves. That is, no vibration is detected when the portable television receiving apparatus 101 is placed on a desk or the like or is stationary. At this time, the vibration sensor 10 outputs a first state transition detection signal. Further, when the portable television receiving apparatus 101 is moving, the main body has some vibration, and at this time, the second state transition detection signal is output. In the portable television receiver 101, the television receiver 19 receives and selects a television broadcast, outputs video / audio / information data, and performs a basic television function of user input operation and data storage.

  In the stationary television receiver 102, the television receiver 18 receives and selects a television broadcast, outputs video / audio / information data, and performs a user's input operation and basic television functions for data storage. An infrared receiving unit 16 as a receiving unit that receives a remote control signal receives a remote control signal including control information such as channel information and power on / off.

  The operation of the television receiving system having the above configuration will be described with reference to the operation flowchart of the vibration sensor in FIG. 2 and the remote control signal communication procedure diagram in FIG. As shown in FIG. 2, the vibration sensor 10 has two state transition detection signals. First, in step S200, it is determined whether or not it is in a stationary state. When the stationary state is reached, the process proceeds to step S201 to output a first state transition detection signal. Next, in step S202, it is determined whether or not it is in a vibration state. If it becomes a vibration state, it will progress to step S203 and will output a 2nd state transition detection signal. And it returns to S200 which is the first step.

  As shown in FIG. 1, the control unit 4 of the television receiver 19 inputs a signal from the vibration sensor 10 and determines whether the signal has changed to the first or second state transition detection signal. As a result, it can be determined whether the portable television receiver 101 is installed or has started moving. In other words, the time point when the process changed from step S200 to step S201 is the time when the movement is completed. Further, the time point when the process changes from step S202 to step S203 is when the installation state is changed to the movement state.

  FIG. 3 is a diagram showing a remote control signal communication procedure between the portable television receiver 101 and the stationary television receiver 102. FIG. 3A shows a TV program using the portable TV receiver 101, and moves to the living room by holding it in the hand, so that the stationary TV receiver 102 and an infrared remote control signal are transmitted. Assume that you are in a place where you can communicate. In such a case, as shown in the figure, the state has changed to a state in which vibration is not detected. At this time, a change to the first state transition detection signal from the vibration sensor 10 is detected, and the portable television receiving device 101 is detected. The infrared transmitter 9 adds the channel selection information such as the channel information received at that time to the remote control signal and transmits it.

  The infrared receiver 16 of the stationary television receiver 102 can input a remote control signal and select a program based on the channel selection information. As a result, the viewer simply enters the living room and places the portable television receiver 101 on a desk or the like so that the stationary television receiver 102 is automatically controlled. There is an effect that the program that has been played can be continuously viewed without any special operation.

  In order to allow the stationary television receiving apparatus 102 to be turned on and viewed even when no power is applied such as in a standby state, a power signal for applying power is added to the remote control signal, and the stationary television receiver 102 is installed. When the stationary television receiving apparatus 102 receives the first state transition detection signal and the power supply signal, control may be performed so that the power of the apparatus is applied by the power supply signal. Also, if it has already been applied, it can be ignored.

  Further, the channel information may be the position number or channel number of the remote controller, or the portable TV receiving apparatus 101 and the stationary TV receiving apparatus 102 store the conversion table of the mutual channel information in advance or on each side for viewing. It is possible to set a program or a broadcasting station to be switched according to the intention of the person.

  Next, FIG. 3B shows a television program being viewed using the stationary television receiver 102, and the portable television receiver 101 placed on a desk is picked up and moved to another room. It is assumed that the user continues to watch the program using the portable television receiver 101. As shown in the figure, when a transition is made to a state in which vibration is detected, a change to the second state transition detection signal from the vibration sensor 10 is detected at this time, and infrared transmission of the portable television receiver 101 is performed. The unit 9 can turn off the power of the stationary television receiver 102 based on the second state transition detection signal. At this time, the portable television receiving device 101 selects a program from the channel selection information received previously.

  If another viewer continues to watch the stationary television receiver 102, it is rather undesirable to turn off the power. In this case, the operation based on the second state transition detection signal can be used in order to make the operation distinct from the control by the normal remote control signal. Therefore, when viewing is not started based on the channel selection information from the portable television receiver 101, it is possible to set in advance so as not to turn off the power regardless of the previous control method. Further, as a screen display, the power may be turned off only when there is a prior notice that the power is turned off at this time and control from the viewer by a remote control signal or the like has not been performed for a while.

(Second Embodiment)
FIG. 4 is a block diagram showing a television receiving system according to the second embodiment of the present invention. In FIG. 4, 101 is a portable television receiver, 102 is a stationary television receiver, and in addition to the components in FIG. 1, an infrared receiver 11 as a receiver for receiving a remote control signal and a transmitter for outputting a remote control signal It is the structure which added the infrared transmission part 17 as. The functions of the television receivers 18 and 19, the vibration sensor 10, the infrared transmitter 9, and the infrared receiver 16 are the same as those in the first embodiment.

  The operation of the television receiving system configured as described above will be described with reference to the remote control signal communication procedure diagram of FIG. FIG. 5A shows a TV program using the portable TV receiver 101, and moves it by holding it in the living room to enter the living room etc. Assume that you are in a place where you can communicate. In such a case, as shown in the figure, the transition is made to a state where no vibration is detected, and at this time, the control unit 4 detects a change from the vibration sensor 10 to the first state transition detection signal.

  In step S11, the infrared transmitter 9 of the portable television receiver 101 adds the first state transition detection signal to the remote control signal and transmits it. The stationary television receiver 102 receives the remote control signal at the infrared receiver 16. Here, the stationary television receiving apparatus 102 recognizes that the channel selection information received by the portable television receiving apparatus 101 at that time is ready to be delivered.

  Next, in step S12, if the stationary television receiving apparatus 102 is in a standby state at that time, power is applied to the respective units in order to set the receiving state. Then, in order to request channel selection information, a viewing state signal S1 indicating whether it is waiting or receiving is added from the infrared transmitter 17 to the remote control signal and transmitted. If the stationary television receiving apparatus 102 is set not to receive control from the portable television receiving apparatus 101, a signal that can be used to determine whether or not the viewing state signal S2 is locked is added to the remote control signal and transmitted. To do. The portable television receiver 101 receives the remote control signal at the infrared receiver 11.

  Next, in step S13, if the stationary television receiving apparatus 102 is not in the locked state based on the viewing state signals S1 and S2, the portable television receiving apparatus 101 transmits channel selection information related to the program received at that time to the infrared transmission unit. 9 is added to the remote control signal and transmitted. The stationary television receiver 102 receives the remote control signal at the infrared receiver 16.

  In step S14, the stationary television receiving apparatus 102 performs channel selection control based on the received channel selection information, and can select a program received by the portable television receiving apparatus 101. Further, the reception response signal is transmitted as a remote control signal. The portable television receiving apparatus 101 can save power by receiving the remote control signal and setting itself to a standby state.

  Next, FIG. 5B shows a television program being viewed using the stationary television receiver 102, and the portable television receiver 101 placed on a desk or the like is picked up and moved to another room or the like. It is assumed that the user continues to watch the program using the portable television receiver 101. As shown in the figure, the state changes to a state in which vibration is detected. At this time, the control unit 4 detects a change from the vibration sensor 10 to the second state transition detection signal. Based on this, if the portable television receiver 101 is in a standby state, power is applied to each part thereof. However, each unit related to reception / display such as the channel selection unit 2, the demodulation unit 3, and the display unit 6 is not necessary at this time, and does not need to be particularly operated.

  In step S21, the infrared transmission unit 9 of the portable television receiver 101 adds the second state transition detection signal to the remote control signal and transmits it. The stationary television receiver 102 receives the remote control signal at the infrared receiver 16. Here, the stationary television receiver 102 can recognize that the portable television receiver 101 is about to start moving at that time.

  Next, in step S22, if the stationary television receiving apparatus 102 is in a standby state at that time, power is applied to each unit in order to enter a reception state. Then, the channel selection information and the viewing state signal S1 indicating whether it is waiting or receiving are added from the infrared transmitter 17 to the remote control signal and transmitted. As a result, the channel selection information related to the program received at that time or the program received before entering standby is transmitted.

  If the stationary television receiver 102 is set so as not to receive control from the portable television receiver 101, a signal that can determine whether or not the viewing state signal S2 is locked is added to the remote control signal. Send. The portable television receiver 101 receives the remote control signal at the infrared receiver 11.

  Next, in step S23, the portable television receiving device 101 performs channel selection control based on the received channel selection information, and continuously watches the program received by the stationary television receiving device 102 or the last received program. become able to. Next, when the received viewing state signal S2 is not set to locked, a signal for shutting off the power of the stationary television receiving apparatus 102 is added from the infrared transmitter 9 to the remote control signal via the remote control signal. Send. The stationary television receiver 102 can receive the remote control signal and shut off the power.

  In step 24, the stationary television receiving apparatus 102 adds a viewing state signal to the remote control signal and transmits it to make a reception response. Upon receiving this, the portable television receiving apparatus 101 can recognize whether the power of the stationary television receiving apparatus 102 has been shut off or whether the program is being received in a locked state. Therefore, in the mobile television receiver 101 that is moving, there is an effect that it is possible to provide useful information to the viewer when the power of the stationary television receiver 102 is not cut off by voice or screen display.

  Note that the portable television receiver 101 may be provided with the timer 13 and may have a timer function capable of measuring time. In this case, a timer function that takes time from when the portable television receiving device 101 transmits the first or second state transition signal to when a predetermined response such as a viewing state signal from the stationary television receiving device 102 is made is used. measure. If there is no predetermined response for a certain time, the first or second state transition signal is retransmitted. In this way, even if communication cannot be performed due to a temporary failure, the operation can be reliably performed with the retransmitted signal.

  Further, the number of retransmissions may be terminated at a predetermined number. In this case, since there is no predetermined response to the retransmitted signal, it can be determined that there is no stationary television receiver 102 or that the power supply of all functions of the stationary television receiver 102 is completely OFF, Subsequent operations can be aborted.

  Furthermore, the viewing state signal S1 may be a signal that is different between standby and reception. In this way, the above-described series of operations are performed while waiting, but when receiving, it can be determined that another person is already viewing and the subsequent signals can be prevented from being transmitted. .

(Third embodiment)
FIG. 6 is a block diagram showing a television receiving system in the third embodiment of the present invention. In FIG. 6, 101 and 202 are portable television receivers, and 102 and 203 are stationary television receivers. The infrared transmission unit 9 and the infrared reception unit 11 shown in FIG. 4 are integrated and represented as an infrared transmission / reception unit 12, and 15, 32, and 36 are also infrared transmission / reception units. The functions of the television receivers 18, 19, 31, and 36 and the vibration sensors 10, 30 are the same as in the second embodiment.

  Hereinafter, the operation of the television receiving system configured as described above will be described with reference to FIG. Here, a user is watching a TV program using the portable TV receiver 101, moves it in his / her hand, enters a living room, etc., and includes other portable TV receivers and a plurality of stationary TV receivers. It is assumed that the remote control signals can be transmitted and received between each other. As shown in the figure, the portable television receiver 101 can transmit and receive a remote control signal to and from the portable television receiver 202 and the two stationary television receivers 102 and 203.

  As already described in the second embodiment, the portable television receiving apparatus 101 is viewing by exchanging the first or second state transition detection signal, the viewing state signal, and the channel selection information with another apparatus. The program information is transferred to other devices so that the program can be viewed continuously. However, if applied to such a situation as it is, transmission of remote control signals may occur simultaneously in a plurality of devices, and interference will occur and normal operation cannot be expected. Therefore, when exchanging such information, it is assumed that its own unique number and the unique number of the target device to receive the remote control signal are added and transmitted. Also, the unique number of the device that continues the program to be viewed is stored in advance.

  For example, when a viewing program is continued between the portable television receiving device 101 and the stationary television receiving device 102, for example, 102 as a target device to receive the own unique number such as 101 and the remote control signal. A remote control signal is transmitted with a unique number such as. Each device that has received the remote control signal detects whether or not its own unique number is included, and if so, responds to it. At this time, the remote control signal is transmitted by adding its own unique number and the unique number of the transmission source device. In this way, even if a plurality of devices can simultaneously transmit and receive remote control signals to each other, there is no crosstalk because there is only one device that responds. In this way, even when a plurality of devices can communicate at the same time, the program to be viewed can be continued without interruption.

  In the above embodiment, it is assumed that a plurality of television receivers are arranged in an environment such as one room and remote control signals can be transmitted / received to / from each other. In such a case, it is also useful to design the directivity of the remote control transmission unit to be quite narrow and to design the reception unit to be sufficiently wide so that a set of devices that can communicate with each other. Similarly, if the transmission power is reduced and the transmission unit and the reception unit are installed close to each other, the same state as described above can be obtained, so that this method also has an effect that the viewing program can be reliably continued. In addition, since each device has a unique number such as 101 or 102, the remote control signal is not only transmitted / received by infrared rays but also wireless communication such as a home wireless LAN (local area network) or Bluetooth (registered trademark). It is also possible to transmit using.

  Other operations, operations, and effects are the same as those in the second embodiment.

  The reception switching function and method of the television reception system according to the present invention are useful because it is possible to automatically switch the reception device between the portable television reception device and the stationary television reception device in a simple manner.
