  The broadcast receiving apparatus 30 receives broadcast data (including audio data) of a channel selected from broadcast data of a plurality of channels, converts the audio data into HDMI data, and transmits the HDMI data to the AV amplifier 20. The AV amplifier 20 performs D / A conversion, volume adjustment processing and amplification processing on the audio data received from the broadcast receiving apparatus, outputs the audio data to a connected speaker, and reproduces the audio.

  FIG. 1 is a block diagram showing the configuration of the AV amplifier 20 and the broadcast receiving device 30. The AV amplifier 20 and the broadcast receiving apparatus 30 comply with, for example, the HDMI standard and are connected to each other via an HDMI cable.

[Configuration of Broadcast Receiver 30]
The broadcast receiving device 30 includes a control unit 31, a memory 32, a tuner 33, an HDMI transmission unit 34, an operation unit 35, a display unit 36, and an HDMI terminal 37.

  The tuner 33 receives broadcast data of one channel number selected by user operation from broadcast data (including audio data) of a plurality of channel numbers, and supplies it to the HDMI transmission unit 34.

  The HDMI transmission unit 34 generates HDMI data from the audio data supplied from the tuner, and transmits the HDMI data to the AV amplifier 20 via the HDMI terminal. Note that when the broadcast data includes video data, the HDMI data includes video data.

  The operation unit 35 receives a user operation, and is a remote control transceiver, an operation button provided on the housing of the broadcast receiving apparatus 30, or the like. When an instruction to change (select) the channel number is input by a user operation, the operation unit 35 supplies the selected channel number to the control unit 31. The display unit 36 displays the selected channel number and the like, and is an LCD, FL tube, or the like.

  The control part 31 performs each process mentioned later based on the operation | movement program of the broadcast receiving apparatus 30 stored in the memory 32, and is a microcomputer, CPU, etc. The control unit 31 is connected to the control unit 21 of the AV amplifier 20 via the CEC line of the HDMI cable, and transmits / receives commands and notifications to / from the control unit 21 of the AV amplifier 20 via the CEC line. Note that commands and notifications can be transmitted and received using other communication lines instead of the CEC line of the HDMI cable.

  When the channel number received by the tuner 33 is changed, the control unit 31 transmits a channel change notification including the changed channel number (current channel number) to the control unit 21 of the AV amplifier 20 via the CEC line. To do.

[Configuration of AV amplifier]
The AV amplifier 20 includes a control unit 21, a memory 22, an HDMI receiving unit 23, an audio processing unit 24, an operation unit 25, a display unit 26, and an HDMI terminal 27.

  The HDMI receiving unit 23 receives the HDMI data transmitted from the HDMI transmitting unit 34 of the broadcast receiving device 30 via the HDMI terminal 27, generates original audio data from the received HDMI data, and generates an audio processing unit 24. To supply.

  The audio processing unit 24 performs processing such as D / A conversion, signal processing, volume adjustment processing, and amplification processing on the audio data supplied from the HDMI receiving unit 23, and outputs audio to the speaker 60 connected to the outside. Supply the signal. A volume value (this volume value is referred to as an output volume value) that the audio processing unit 24 adjusts to the audio data is set by an instruction from the control unit 21.

  The memory 22 stores a volume value table shown in FIG. The volume value table registers the output volume value set by the user operation for each channel number, and when the channel number is changed, the volume value corresponding to the changed channel number is read. This is a table for setting as an output volume value. In the volume value table, the volume value and the number of times of reading are registered in association with the channel number of the broadcast data received by the broadcast receiving device 30. As the volume value, an output volume value set by a user operation when the audio data of the current channel number is received by the AV amplifier 20 and output to the speaker is registered. The number of times of reading is the number of times that the volume value of the changed channel number is read and set as the output volume value when the channel number of the broadcast data received by the broadcast receiving device 30 is changed.

  The operation unit 25 receives user operations, and includes a remote control transceiver, operation buttons provided on the housing of the AV amplifier 20, and the like. The operation unit 25 receives a volume value by a user operation and supplies the volume value to the control unit 21.

  The control unit 21 executes each process to be described later based on an AV amplifier operation program stored in the memory 22, and is a microcomputer, a CPU, or the like. The control unit 21 is connected to the control unit 31 of the broadcast receiving device 30 via the CEC line of the HDMI cable, and transmits / receives commands and notifications to / from the control unit 31 of the broadcast receiving device 30 via the CEC line. Note that commands and notifications can be transmitted and received using other communication lines instead of the CEC line of the HDMI cable.

  When receiving the channel change notification from the control unit 31 of the broadcast receiving device 30, the control unit 21 reads the volume value corresponding to the changed channel from the volume value table and sets it as the output volume value. Further, the control unit 31 changes the output volume value when the volume value is changed by a user operation. In addition, when the output volume value is different from the volume value registered in the volume value table, the control unit 31 changes the volume value in the volume value table to the output volume value.

[Operation]
The operation of this embodiment will be described below. FIG. 3 is a flowchart showing the process of the control unit 31 of the broadcast receiving apparatus 30, and FIG. 4 is a flowchart showing the process of the control unit 21 of the AV amplifier 20.

  As shown in FIG. 3, the control unit 31 of the broadcast receiving apparatus 30 determines whether or not an instruction to change the channel number of broadcast data is input by a user operation (S31). When an instruction to change the channel number is input (YES in S31), the control unit 31 controls the tuner 33 to change the received channel number to the channel number selected by the user operation (S32). In response to this, the tuner 33 changes the channel number of the received broadcast data to the channel number designated by the control unit 31. Subsequently, the control unit 31 transmits a channel change notification including the changed channel number to the control unit 21 of the AV amplifier 20 via the CEC line (S33). For example, when the channel number is changed (or selected), a channel change notification including the channel number 1 is transmitted.

  As shown in FIG. 4, the control unit 21 of the AV amplifier 20 determines whether or not a channel change notification is received from the control unit 31 of the broadcast receiving apparatus 30 via the CEC line (S1). When the channel change notification is not received (NO in S1), the control unit 21 determines whether or not an instruction to change the volume value is input by a user operation (S9). If no instruction to change the volume value is input (NO in S9), it is determined whether the state in which the output volume value and the volume value registered in the volume value table are different for a predetermined time has continued (S11). . When the state where the output volume value and the volume value registered in the volume value table do not continue for a predetermined time, the process returns to S1. That is, the control unit 21 repeatedly executes the determination processes of S1, S9, and S11.

  When the channel change notification is received in S1 (YES in S1), the control unit 21 reads the channel number included in the channel change notification, searches the volume value table for the channel number (S2), It is determined whether or not the channel number is registered in the volume value table (S3). The control unit 21 causes the display unit 26 to display the channel number included in the channel change notification as the current channel number.

[When the current channel number is not registered in the volume value table]
If the channel number is not registered in the volume value table due to the reason such as the channel number selected for the first time (NO in S3), the control unit 21 can register an empty area (the volume value of this channel number can be registered in the volume value table). (S6). If an empty area exists in the volume value table (YES in S6), the process proceeds to S8.

  On the other hand, when there is no free area in the volume value table (NO in S6), the control unit 21 deletes the information of the channel number with the smallest number of readings from the volume value table, thereby generating a free area (S7). . In S8, the control unit 21 creates a column of the current channel number in the volume value table in order to register the volume value of the current channel number, and registers the current output volume value in the created column. For example, if channel number 1 is included in the channel change notification and the channel number 1 field does not exist in the volume value table, the channel number 1 field is generated and, for example, the current output volume value 40 is registered. The

  Subsequently, in S9, when an instruction to change the volume value is input by a user operation (YES in S9), the control unit 21 changes the output volume value and the display volume value. For example, when the current channel number is 1 and the output volume value is 40 and the display volume value is 40 and the volume value is increased by 10 and changed to 50 by a user operation, the output volume value is 50, The display volume value is changed to 50.

  Subsequently, in S11, if the state in which the output volume value and the volume value registered in the volume value table are different from each other for a predetermined time or longer with respect to the current channel number (YES in S11), the output volume value is It is registered as a volume value of the current channel number in the value table (S12). For example, when the output volume value of channel number 1 is 50 and the volume value registered in association with the current channel number in the volume value table is 40, the output volume value 50 is It is registered as the volume value of channel number 1 in the volume value table.

[When the current channel number is registered in the volume value table]
If the current channel number is registered in the volume value table in S3 (YES in S3), the volume value corresponding to the current channel number is read from the volume value table and set as the output volume value (S4). At this time, the display volume value is not changed in this example. For example, when the current output volume value is 30, the display volume value is 40, and the volume value of the volume value table corresponding to the current channel number 1 is 50, the volume value 50 is read and the output volume value Is changed to 50, and the display volume value remains at 40.

  Subsequently, the control unit 2 increments the read count corresponding to the current channel number by 1 in the volume value table (S5).

  Subsequently, in S9, when an instruction to change the volume value is input by a user operation (YES in S9), the control unit 21 changes the output volume value and the display volume value. For example, when the current channel number is 1, when the volume value is increased by 5 and changed to 55 by the user operation from the state of the output volume value 50 and the display volume value 40, the output volume value 55 and the display volume value 45 Changed to

  Subsequently, in S11, if the state in which the output volume value and the volume value registered in the volume value table are different from each other for a predetermined time or longer with respect to the current channel number (YES in S11), the output volume value is It is registered as a volume value of the current channel number in the value table (S12). For example, when the output volume value of channel number 1 is 55 and the volume value registered in association with the current channel number in the volume value table is 50, the output volume value 55 is It is registered as the volume value of channel number 1 in the volume value table.

Next, an example of processing based on the flowchart of FIG. 4 will be described.
(1) When the channel number included in the channel change notification is 1, channel number 1 is displayed on the display unit 26 as the current channel number. A column of channel number 1 is newly generated in the volume value table. When the current output volume value is 40 and the display volume value is 40, the output volume value 40 is registered as the volume value of channel number 1 in the volume value table. When the volume value is increased by 10 and changed to 50 by a user operation, the output volume value is changed to 50 and the display volume value is changed to 50. When this state continues for a predetermined time or more, the output volume value 50 is registered as the volume value of channel number 1 in the volume value table.

(2) When the channel number included in the next channel number notification is 2, the channel number 2 is displayed on the display unit 26 as the current channel number. A channel number 2 field is newly generated in the volume value table. Since the current output volume value is 50 and the display volume value is 50, the output volume value 50 is registered as the volume value of channel number 2 in the volume value table. When the volume value is decreased by 20 and changed to 30 by a user operation, the output volume value is changed to 30 and the display volume value is changed to 30. When this state continues for a predetermined time or more, the output volume value 30 is registered as the volume value of channel number 2 in the volume value table.

(3) When the channel number included in the next channel number notification is 3, the channel number 3 is displayed on the display unit 26 as the current channel number. A column for channel number 3 is newly generated in the volume value table. Since the current output volume value is 30 and the display volume value is 30, the output volume value 30 is registered as the volume value of channel number 3 in the volume value table. When the volume value is increased by 10 and changed to 40 by a user operation, the output volume value is changed to 40 and the display volume value is changed to 40. When this state continues for a predetermined time or more, the output volume value 40 is registered as the volume value of channel number 3 in the volume value table.

(4) When the channel number included in the next channel change notification is 1, the channel number 1 is displayed on the display unit 26 as the current channel number. Since the column of channel number 1 generated in (1) already exists in the volume value table, the volume value 50 is read and the output volume value is changed to 50. At this time, the display volume value remains at 40. When the volume value is increased by 5 and changed to 55 by a user operation, the output volume value is changed to 55 and the display volume value is changed to 45. When this state continues for a predetermined time or more, the output volume value 55 is registered as the volume value of channel number 1 in the volume value table.

(5) When the channel number included in the next channel change notification is 2, the channel number 2 is displayed on the display unit 26 as the current channel number. Since the column of the channel number 2 generated in (2) already exists in the volume value table, the volume value 30 is read and the output volume value is changed to 30. At this time, the display volume value remains 45.

  FIG. 5 is a flowchart showing the processing of the control unit 21 of the AV amplifier 20 according to another preferred embodiment. The process of FIG. 5 differs from the process of FIG. 4 only in that S4 is changed to S24. In S24, the control unit 21 reads the volume value corresponding to the current channel number from the volume value table, and changes both the output volume value and the display volume value to the read volume value.

An example of processing based on the flowchart of FIG. 5 will be described.
(1) When the channel number included in the channel change notification is 1, channel number 1 is displayed on the display unit 26 as the current channel number. A column of channel number 1 is newly generated in the volume value table. When the current output volume value is 40 and the display volume value is 40, the output volume value 40 is registered as the volume value of channel number 1 in the volume value table. When the volume value is increased by 10 and changed to 50 by a user operation, the output volume value is changed to 50 and the display volume value is changed to 50. When this state continues for a predetermined time or more, the output volume value 50 is registered as the volume value of channel number 1 in the volume value table.

(2) When the channel number included in the next channel number notification is 2, the channel number 2 is displayed on the display unit 26 as the current channel number. A channel number 2 field is newly generated in the volume value table. Since the current output volume value is 50 and the display volume value is 50, the output volume value 50 is registered as the volume value of channel number 2 in the volume value table. When the volume value is decreased by 20 and changed to 30 by a user operation, the output volume value is changed to 30 and the display volume value is changed to 30. When this state continues for a predetermined time or more, the output volume value 30 is registered as the volume value of channel number 2 in the volume value table.

(3) When the channel number included in the next channel number notification is 3, the channel number 3 is displayed on the display unit 26 as the current channel number. A column for channel number 3 is newly generated in the volume value table. Since the current output volume value is 30 and the display volume value is 30, the output volume value 30 is registered as the volume value of channel number 3 in the volume value table. When the volume value is increased by 10 and changed to 40 by a user operation, the output volume value is changed to 40 and the display volume value is changed to 40. When this state continues for a predetermined time or more, the output volume value 40 is registered as the volume value of channel number 3 in the volume value table.

(4) When the channel number included in the next channel change notification is 1, the channel number 1 is displayed on the display unit 26 as the current channel number. Since the column of channel number 1 generated in (1) already exists in the volume value table, the volume value 50 is read and the output volume value and the display volume value are changed to 50. When the volume value is increased by 5 and changed to 55 by a user operation, both the output volume value and the display volume value are changed to 55. When this state continues for a predetermined time or more, the output volume value 55 is registered as the volume value of channel number 1 in the volume value table.

(5) When the channel number included in the next channel change notification is 2, the channel number 2 is displayed on the display unit 26 as the current channel number. Since the column of channel number 2 generated in (2) already exists in the volume value table, the volume value 30 is read, and the output volume value and the display volume value are changed to 30.

  Through the above processing, the volume value is stored in association with each channel number, and when the channel number is changed, the volume value corresponding to the channel number included in the channel change notification is read and set as the output volume value. Thus, it is not necessary to change the volume value by a user operation every time the channel is changed.
