以下、図面を参照して本発明の実施の形態について説明する。
Ａ．第１実施形態
（１）構成
図１は本発明の第１実施形態によるホームネットワーク装置１００の構成を示すブロック図である。この図に示すホームネットワーク装置１００は、放送受信部１０、制御部２０、コンテンツ蓄積部３０および配信部４０から構成され、宅内の各部屋に設置されるテレビ５０−１〜５０−３がそれぞれ要求する受信チャンネルの放送を配信する。 Embodiments of the present invention will be described below with reference to the drawings.
A. First Embodiment (1) Configuration FIG. 1 is a block diagram showing a configuration of a home network device 100 according to a first embodiment of the present invention. The home network device 100 shown in this figure includes a broadcast receiving unit 10, a control unit 20, a content storage unit 30, and a distribution unit 40, and each of the televisions 50-1 to 50-3 installed in each room in the home requests it. Broadcast the broadcast of the receiving channel.

リモコン５１〜５３は、周知の赤外線リモコン等で構成され、電源オンオフを指示する電源スイッチや受信チャンネルの切り替えを指示するチャンネルスイッチ等を備える。これらリモコン５１〜５３では、チャンネルスイッチの操作に応じたチャンネル設定信号を発生する。チャンネル設定信号は、リモコン識別データ、優先権の有無および受信チャンネル番号を含む。これらリモコン５１〜５３のいずれかの１つには、受信チャンネルの切換えを優先的に行わせる優先権が付与される。本実施形態では、一例としてリモコン５１に優先権を付与する。 The remote controllers 51 to 53 are configured by a known infrared remote controller or the like, and include a power switch for instructing power on / off, a channel switch for instructing switching of a reception channel, and the like. These remote controllers 51-53 generate channel setting signals in accordance with channel switch operations. The channel setting signal includes remote control identification data, presence / absence of priority, and reception channel number. Any one of these remote controllers 51 to 53 is given a priority to preferentially switch the reception channel. In the present embodiment, priority is given to the remote controller 51 as an example.

テレビ５０−１〜５０−３は、配信部４０（後述する）から供給される映像・音声信号を映像表示および音声再生する一方、それぞれリモコン５１〜５３から赤外線送出されるチャンネル設定信号を受信して制御部２０に出力する。放送受信部１０は、複数のチューナを有し、制御部２０から供給される受信チャンネル番号で指定される各放送信号をそれぞれ受信復調してコンテンツ蓄積部３０に出力する。 The televisions 50-1 to 50-3 display and reproduce the video / audio signals supplied from the distribution unit 40 (described later), and receive channel setting signals transmitted from the remote controllers 51 to 53, respectively. To the control unit 20. The broadcast receiving unit 10 includes a plurality of tuners, receives and demodulates each broadcast signal specified by the reception channel number supplied from the control unit 20, and outputs the received broadcast signal to the content storage unit 30.

制御部２０は、チャンネルテーブルＣＴＬを有する。チャンネルテーブルＣＴＬとは、上述したチャンネル設定信号（リモコン識別データ、優先権の有無、受信チャンネル番号）を各テレビ５０−１〜５０−３毎に記憶したテーブルである。チャンネルテーブルＣＴＬでは、チャンネル設定が行われる毎に新たなチャンネル設定信号が更新登録される。制御部２０では、こうしたチャンネルテーブルＣＴＬを参照したチャンネル変更処理（後述する）を行い、チャンネル変更された映像・音声信号を指定の視聴系統（テレビ５０−１〜５０−３）に配信するよう配信部４０に指示する。 The control unit 20 has a channel table CTL. The channel table CTL is a table in which the above-described channel setting signal (remote control identification data, presence / absence of priority, reception channel number) is stored for each television 50-1 to 50-3. In the channel table CTL, a new channel setting signal is updated and registered every time channel setting is performed. The control unit 20 performs channel change processing (to be described later) with reference to the channel table CTL, and distributes the channel / changed video / audio signals to the specified viewing system (TVs 50-1 to 50-3). The unit 40 is instructed.

具体的には、例えばテレビ５０−１〜５０−３がそれぞれ「Ａｃｈ」、「Ｂｃｈ」、「Ｃｃｈ」を視聴している状態で、優先権を有するリモコン５１がテレビ５０−２の受信チャンネルを「Ａｃｈ」に変更するチャンネル設定信号を発生した場合、テレビ５０−２の受信チャンネルを「Ａｃｈ」に変更すると同時に、テレビ５０−１の受信チャンネルを「Ｂｃｈ」に変更する。つまり、チャンネル変更処理では、ある視聴系統の受信チャンネルが変更された場合に、変更以前の受信チャンネルを他の視聴系統にアサインするようになっている。 Specifically, for example, when the televisions 50-1 to 50-3 are viewing “Ach”, “Bch”, and “Cch”, respectively, the remote controller 51 having the priority right selects the reception channel of the television 50-2. When the channel setting signal to be changed to “Ach” is generated, the reception channel of the television 50-2 is changed to “Ach”, and at the same time, the reception channel of the television 50-1 is changed to “Bch”. That is, in the channel change process, when a reception channel of a certain viewing system is changed, a reception channel before the change is assigned to another viewing system.

制御部２０では、テレビ５０−１〜５０−３側から出力されるチャンネル設定信号から受信チャンネル番号を抽出して放送受信部１０に供給する。コンテンツ蓄積部３０は、制御部２０の制御の下に、放送受信部１０が受信復調した各受信チャンネルの映像・音声信号を配信部４０にスルー出力したり、あるいは制御部２０が指定する受信チャンネルの映像・音声信号を録画又は再生する。配信部４０は、コンテンツ蓄積部３０から出力される映像・音声信号を、制御部２０が指定する視聴系統（テレビ５０−１〜５０−３）に配信出力する。 In the control unit 20, the reception channel number is extracted from the channel setting signal output from the TV 50-1 to 50-3 side and supplied to the broadcast receiving unit 10. Under the control of the control unit 20, the content storage unit 30 outputs the video / audio signal of each reception channel received and demodulated by the broadcast reception unit 10 to the distribution unit 40, or the reception channel designated by the control unit 20 Record or play back video / audio signals. The distribution unit 40 distributes and outputs the video / audio signal output from the content storage unit 30 to the viewing system (TVs 50-1 to 50-3) designated by the control unit 20.

（２）動作
次に、図２を参照して制御部２０が実行するチャンネル変更処理の動作を説明する。テレビ５０−１〜５０−３のいずれかからチャンネル設定信号が入力されると、制御部２０は図２に図示するチャンネル変更処理を実行し、ステップＳＡ１に進む。ステップＳＡ１では、前述したチャンネルテーブルＣＴＬを参照してチャンネル設定信号を出力したテレビとリモコンの組合わせが前回と同じであるか否かを判断する。 (2) Operation Next, the operation of the channel change process executed by the control unit 20 will be described with reference to FIG. When a channel setting signal is input from any of the televisions 50-1 to 50-3, the control unit 20 executes a channel change process illustrated in FIG. 2 and proceeds to step SA1. In step SA1, it is determined by referring to the above-mentioned channel table CTL whether or not the combination of the television and the remote controller that has output the channel setting signal is the same as the previous time.

例えば、リモコン５２の操作によりテレビ５０−２で「Ｂｃｈ」を視聴していた状態で、リモコン５２を操作してテレビ５０−２のチャンネルを「Ｃｃｈ」に変更したとする。そうすると、この場合にはテレビとリモコンの組合わせが前回と同じになる為、ステップＳＡ１の判断結果は「ＹＥＳ」になり、ステップＳＡ２に進む。 For example, it is assumed that the channel of the television 50-2 is changed to “Cch” by operating the remote controller 52 while “Bch” is being viewed on the television 50-2 by operating the remote controller 52. Then, in this case, since the combination of the television and the remote controller is the same as the previous time, the determination result in step SA1 is “YES”, and the process proceeds to step SA2.

ステップＳＡ２では、チャンネル設定信号から抽出した受信チャンネル番号を放送受信部１０に供給する一方、チャンネル変更された映像・音声信号をテレビ５０−２に配信するよう配信部４０に指示する。これにより、チャンネル変更の指示のあったテレビの受信チャンネルのみが変更される。つまり、上記一例の場合、テレビ５０−２の受信チャンネルが「Ｂｃｈ」から「Ｃｃｈ」に変更される。この後、制御部２０は本処理を終えてチャンネル設定信号入力待ちの状態となる。 In step SA2, the reception channel number extracted from the channel setting signal is supplied to the broadcast receiving unit 10, while the distribution unit 40 is instructed to distribute the channel-changed video / audio signal to the television 50-2. As a result, only the reception channel of the television instructed to change the channel is changed. That is, in the above example, the reception channel of the television 50-2 is changed from “Bch” to “Cch”. Thereafter, the control unit 20 finishes this process and enters a channel setting signal input waiting state.

一方、チャンネル設定信号を出力したテレビとリモコンの組合わせが前回と異なる場合、例えばリモコン５２の操作によりテレビ５０−２が「Ａｃｈ」を視聴している状態で、優先権を有していないリモコン５３を操作してテレビ５０−２のチャンネルを「Ｃｃｈ」に変更したとする。そうすると、テレビとリモコンの組合わせが前回と異なるので、上記ステップＳＡ１の判断結果が「ＮＯ」になり、ステップＳＡ３に進む。 On the other hand, if the combination of the TV that has output the channel setting signal and the remote controller is different from the previous one, for example, a remote controller that does not have priority when the TV 50-2 is viewing “Ach” by operating the remote controller 52. It is assumed that the channel of the television 50-2 is changed to “Cch” by operating 53. Then, since the combination of the television and the remote controller is different from the previous time, the determination result in step SA1 is “NO”, and the process proceeds to step SA3.

ステップＳＡ３では、優先権を持つリモコンのチャンネル変更であるか否かを判断する。上記一例の場合には、優先権を有していないリモコン５３の操作によるチャンネル変更なので、判断結果は「ＮＯ」となり、上述のステップＳＡ２に進み、チャンネル変更の指示のあったテレビの受信チャンネルのみを変更した後、本処理を終えてチャンネル設定信号入力待ちの状態となる。 In step SA3, it is determined whether or not the channel of the remote controller having priority is changed. In the case of the above example, since the channel is changed by the operation of the remote controller 53 that does not have priority, the determination result is “NO”, the process proceeds to step SA2, and only the reception channel of the television instructed to change the channel is obtained. After changing the above, the present processing is finished and a channel setting signal input waiting state is entered.

これに対し、例えばリモコン５１〜５３の各操作によりテレビ５０−１〜５０−３がそれぞれ「Ａｃｈ」、「Ｂｃｈ」、「Ｃｃｈ」を視聴している状態で、優先権を有するリモコン５１がテレビ５０−２のチャンネルを「Ａｃｈ」に変更するチャンネル設定信号を発生した場合を想定する。この場合、テレビとリモコンの組合わせが前回と異なるから、上記ステップＳＡ１の判断結果は「ＮＯ」となり、ステップＳＡ３に進み、さらに優先権を持つリモコンの操作によるチャンネル変更である為、このステップＳＡ３の判断結果が「ＹＥＳ」になり、ステップＳＡ４に進む。 On the other hand, for example, when the televisions 50-1 to 50-3 are respectively viewing “Ach”, “Bch”, and “Cch” by the operations of the remote controllers 51 to 53, the remote controller 51 having the priority right is the television. Assume that a channel setting signal for changing the channel 50-2 to "Ach" is generated. In this case, since the combination of the TV and the remote control is different from the previous time, the determination result in step SA1 is “NO”, and the process proceeds to step SA3. Further, the channel is changed by operating the remote control with priority. The determination result is “YES”, and the flow proceeds to step SA4.

そして、ステップＳＡ４では、チャンネル変更の指示のあったテレビの現在のチャンネルを同じリモコンが前回チャンネル変更指示を行ったテレビに移動させる。つまり、上記一例の場合には、テレビ５０−２の受信チャンネルを「Ａｃｈ」に変更すると同時に、テレビ５０−１の受信チャンネルを「Ｂｃｈ」に変更するよう配信部４０に指示する。こうして、ある視聴系統の受信チャンネルが変更された場合に、変更以前の受信チャンネルを他の視聴系統にアサインすると、ステップＳＡ５に進む。 In step SA4, the current channel of the television instructed to change the channel is moved to the television to which the same remote controller has instructed the previous channel change. That is, in the above example, the distribution unit 40 is instructed to change the reception channel of the television 50-2 to “Bch” at the same time as changing the reception channel of the television 50-2 to “Ach”. In this way, when the receiving channel of a certain viewing system is changed, if the receiving channel before the change is assigned to another viewing system, the process proceeds to step SA5.

ステップＳＡ５では、チャンネル設定信号から抽出した受信チャンネル番号を放送受信部１０に供給する一方、チャンネル変更された映像・音声信号をテレビ５０−２に配信するよう配信部４０に指示することより、チャンネル変更の指示のあったテレビの受信チャンネルのみを変更した後、本処理を終えてチャンネル設定信号入力待ちの状態となる。 In step SA5, the reception channel number extracted from the channel setting signal is supplied to the broadcast receiving unit 10, while the distribution unit 40 is instructed to distribute the video / audio signal whose channel has been changed to the television 50-2. After changing only the reception channel of the television instructed to change, this processing is finished and the channel setting signal input wait state is entered.

以上のように、第１実施形態では、現在視聴中の受信チャンネルを設定したリモコンを識別するリモコン識別データと、そのリモコンの優先権の有無と、設定した受信チャンネル番号とを含むチャンネル設定信号を、各視聴系統（テレビ５０−１〜５０−３）毎に記憶するチャンネルテーブルＣＴＬを設けておき、チャンネル設定信号が発生する都度、このチャンネルテーブルＣＴＬを参照してテレビとリモコンの組合わせが前回と異なり、かつ優先権を持つリモコンの操作によるチャンネル変更であるか否かを判断する。そして、この条件に合致すれば、チャンネル変更の指示のあった視聴系統の現在の受信チャンネルを同じリモコンが前回チャンネル変更指示を行った視聴系統に移動させる。これにより、ある視聴系統で受信チャンネルが変更された場合に、その変更以前の受信チャネルを即座に他の視聴系統に設定することができる。 As described above, in the first embodiment, the channel setting signal including the remote control identification data for identifying the remote controller that has set the receiving channel currently being viewed, the presence / absence of priority of the remote controller, and the set receiving channel number is provided. A channel table CTL to be stored for each viewing system (TVs 50-1 to 50-3) is provided, and each time a channel setting signal is generated, the combination of the TV and the remote controller is referred to the previous time by referring to this channel table CTL. It is determined whether or not the channel is changed by operating a remote controller having priority. If this condition is met, the current receiving channel of the viewing system instructed to change the channel is moved to the viewing system for which the same remote controller previously instructed to change the channel. Thereby, when a receiving channel is changed in a certain viewing system, the receiving channel before the change can be immediately set to another viewing system.

なお、本実施形態では、ある視聴系統で受信チャンネルが変更された場合に、その変更以前の受信チャネルを即座に他の視聴系統に設定するようにしたが、これに替えて、ある視聴系統で受信チャンネルが変更されたら、その変更以前の受信チャネルを即座に録画させる態様としても良い。例えばテレビ５０−１〜５０−２がそれぞれ「Ａｃｈ」、「Ｂｃｈ」を視聴している状態で、優先権を有するリモコン５１がテレビ５０−２の受信チャンネルを「Ａｃｈ」に変更するチャンネル設定信号を発生したら、テレビ５０−２で視聴していた「Ｂｃｈ」の放送をコンテンツ蓄積部３０に録画させると同時に、テレビ５０−２の受信チャンネルを「Ａｃｈ」に変更する。このようにすることで、放送時刻が重なる２つの番組の一方を視聴しながら他方を録画する為、見たい番組の見逃しを防ぐことが可能になる。 In this embodiment, when a reception channel is changed in a certain viewing system, the reception channel before the change is immediately set to another viewing system. When the reception channel is changed, the reception channel before the change may be recorded immediately. For example, a channel setting signal for the remote controller 51 having priority to change the reception channel of the television 50-2 to “Ach” while the televisions 50-1 to 50-2 are viewing “Ach” and “Bch”, respectively. Is generated, the content storage unit 30 records the broadcast of “Bch” viewed on the television 50-2, and at the same time, the reception channel of the television 50-2 is changed to “Ach”. In this way, since one of the two programs having the same broadcast time is viewed while the other is recorded, it is possible to prevent a program that is desired to be missed.

Ｂ．第２実施形態
（１）構成
図２は本発明の第２実施形態によるホームネットワーク装置の構成を示すブロック図である。この図に示すホームネットワーク装置は、複数の視聴系統（放送受信機６０−１〜６０−３）から構成される。各視聴系統（放送受信機６０−１〜６０−３）は、それぞれリモコン受光部６０ａ、制御部６０ｂ、放送受信部６０ｃ、表示部６０ｄおよび通信部６０ｅから構成される。 B. Second Embodiment (1) Configuration FIG. 2 is a block diagram showing a configuration of a home network device according to a second embodiment of the present invention. The home network device shown in this figure is composed of a plurality of viewing systems (broadcast receivers 60-1 to 60-3). Each viewing system (broadcast receivers 60-1 to 60-3) includes a remote control light receiving unit 60a, a control unit 60b, a broadcast receiving unit 60c, a display unit 60d, and a communication unit 60e.

リモコン受光部６０ａは、リモコン７０〜７２からの赤外線を受光し、当該赤外線により搬送される制御データを復調して制御部６０ｂに出力する。リモコン７０〜７２は、周知の赤外線リモコン等で構成され、電源オンオフを指示する電源スイッチや受信チャンネルの切り替えを指示するチャンネルスイッチ等を備える。 The remote control light receiving unit 60a receives infrared rays from the remote controls 70 to 72, demodulates control data carried by the infrared rays, and outputs the control data to the control unit 60b. The remote controllers 70 to 72 are configured by a known infrared remote controller or the like, and include a power switch for instructing power on / off, a channel switch for instructing switching of a reception channel, and the like.

これらリモコン７０〜７２では、チャンネルスイッチの操作に応じた制御データとしてチャンネル設定信号を発生する。チャンネル設定信号は、自己のリモコン番号、優先権の有無および受信チャンネル番号を含む。したがって、リモコン受光部６０ａは、リモコン７０〜７２のいずれかから制御データ（チャンネル設定信号）を受領した場合、当該制御データを復調して自己のリモコン番号、優先権の有無および受信チャンネル番号を含むチャンネル設定信号を制御部６０ｂに供給する。 These remote controllers 70 to 72 generate channel setting signals as control data corresponding to channel switch operations. The channel setting signal includes its own remote control number, presence / absence of priority, and reception channel number. Therefore, when receiving the control data (channel setting signal) from any of the remote controllers 70 to 72, the remote control light receiving unit 60a demodulates the control data and includes its own remote control number, presence / absence of priority, and reception channel number. A channel setting signal is supplied to the controller 60b.

制御部６０ｂは、リモコン受光部６０ａが出力するチャンネル設定信号から受信チャンネル番号を抽出して放送受信部６０ｃに供給する。また、制御部６０ｂは、上述したチャンネル設定信号（リモコン番号、優先権の有無、受信チャンネル番号）を、チャンネル設定毎に更新登録するチャンネル設定レジスタＣＳＲを有し、このチャンネル設定レジスタＣＳＲを参照したチャンネル変更処理を実行する。チャンネル変更処理では、後述するように、優先権を有するリモコンからのチャンネル変更指示があった場合に、通信部６０ｅを介して他の視聴系統の受信チャンネル変更指示を無線送信する。 The control unit 60b extracts the reception channel number from the channel setting signal output from the remote control light receiving unit 60a, and supplies it to the broadcast receiving unit 60c. Further, the control unit 60b has a channel setting register CSR for updating and registering the above-described channel setting signal (remote control number, presence / absence of priority, reception channel number) for each channel setting, and refers to this channel setting register CSR. Execute channel change processing. In the channel change process, as will be described later, when there is a channel change instruction from a remote controller having priority, a reception channel change instruction for another viewing system is wirelessly transmitted via the communication unit 60e.

具体的には、例えば各視聴系統（放送受信機６０−１〜６０−３）がそれぞれ「Ａｃｈ」、「Ｂｃｈ」、「Ｃｃｈ」を視聴している状態で、優先権を有するリモコン７０が放送受信機６０−２の受信チャンネルを「Ａｃｈ」に変更するチャンネル設定信号を発生した場合、放送受信機６０−２の制御部６０ｂが受信チャンネルを「Ａｃｈ」に変更すると同時に、放送受信機６０−２の制御部６０ｂが通信部６０ｅを介して放送受信機６０−１側に受信チャンネルを「Ｂｃｈ」に変更するよう指示する。つまり、チャンネル変更処理では、ある視聴系統の受信チャンネルが変更された場合に、変更以前の受信チャンネルを他の視聴系統にアサインする。 Specifically, for example, when each viewing system (broadcast receivers 60-1 to 60-3) is viewing “Ach”, “Bch”, and “Cch”, the remote controller 70 having the priority right broadcasts. When a channel setting signal for changing the reception channel of the receiver 60-2 to "Ach" is generated, the control unit 60b of the broadcast receiver 60-2 changes the reception channel to "Ach" and at the same time, the broadcast receiver 60- The second control unit 60b instructs the broadcast receiver 60-1 side to change the reception channel to “Bch” via the communication unit 60e. That is, in the channel change process, when a reception channel of a certain viewing system is changed, a reception channel before the change is assigned to another viewing system.

さらに、制御部６０ｂでは、通信部６０ｅを介して他の視聴系統から受信チャンネルの変更指示を受信した場合、変更指示された受信チャンネル番号を放送受信部６０ｃに供給する。放送受信部６０ｃは、制御部６０ｂから供給される受信チャンネル番号で指定される放送信号をアンテナＡＮＴ１を介して受信復調して表示部６０ｄに出力する。通信部６０ｅは、制御部６０ｂから与えられる送出パケットをアンテナＡＮＴ２から無線送信する一方、他の視聴系統からの送出パケットをアンテナＡＮＴ２を介して受信して制御部６０ｂに出力する。 Further, when receiving a channel change instruction from another viewing system via the communication unit 60e, the control unit 60b supplies the received reception channel number to the broadcast receiving unit 60c. The broadcast receiving unit 60c receives and demodulates the broadcast signal specified by the reception channel number supplied from the control unit 60b via the antenna ANT1, and outputs the received signal to the display unit 60d. The communication unit 60e wirelessly transmits a transmission packet given from the control unit 60b from the antenna ANT2, while receiving a transmission packet from another viewing system via the antenna ANT2 and outputs it to the control unit 60b.

（２）動作
次に、図４〜図５を参照して第２実施形態の動作を説明する。以下では、例えば放送受信機６０−１の制御部６０ｂが実行するチャンネル変更処理について述べる。放送受信機６０−１の受光部６０ａがリモコン７０〜７２のいずれかからチャンネルスイッチの操作に応じた制御データを受領すると、当該制御データを復調して自己のリモコン番号、優先権の有無および受信チャンネル番号を含むチャンネル設定信号を制御部６０ｂに供給する。すると、放送受信機６０−１の制御部６０ｂは、図４に図示するチャンネル変更処理を実行し、ステップＳＢ１に進む。ステップＳＢ１では、前述したチャンネル設定レジスタＣＳＲを参照して、今回のチャンネル設定信号を出力したリモコンが前回と同じであるか否かを判断する。 (2) Operation Next, the operation of the second embodiment will be described with reference to FIGS. Below, the channel change process which the control part 60b of the broadcast receiver 60-1 performs, for example is described. When the light receiving unit 60a of the broadcast receiver 60-1 receives control data corresponding to the operation of the channel switch from any one of the remote controllers 70 to 72, the control data is demodulated to receive its own remote control number, presence of priority, and reception. A channel setting signal including the channel number is supplied to the controller 60b. Then, the control part 60b of the broadcast receiver 60-1 performs the channel change process shown in FIG. 4, and progresses to step SB1. In step SB1, referring to the above-described channel setting register CSR, it is determined whether or not the remote controller that has output the current channel setting signal is the same as the previous one.

例えば、リモコン７１の操作により放送受信機６０−１が「Ｂｃｈ」を視聴していた状態で、同じリモコン７１を操作して放送受信機６０−１のチャンネルを「Ｃｃｈ」に変更したとする。そうすると、この場合には前回と同じリモコンからのチャンネル変更指示となるので、上記ステップＳＢ１の判断結果は「ＹＥＳ」になり、ステップＳＢ２に進み、受光部６０ａが供給するチャンネル設定信号から抽出した受信チャンネル番号を放送受信部６０ｃに供給する。これにより、指示された受信チャンネルに変更する。つまり、上記一例の場合、放送受信機６０−１の受信チャンネルが「Ｂｃｈ」から「Ｃｃｈ」に変更される。この後、制御部２０は本処理を終えてチャンネル設定信号入力待ちの状態となる。 For example, it is assumed that the channel of the broadcast receiver 60-1 is changed to “Cch” by operating the same remote controller 71 while the broadcast receiver 60-1 is viewing “Bch” by operating the remote controller 71. Then, in this case, since the same channel change instruction is given from the remote controller as in the previous case, the determination result in step SB1 is “YES”, the process proceeds to step SB2, and the reception extracted from the channel setting signal supplied by the light receiving unit 60a. The channel number is supplied to the broadcast receiving unit 60c. As a result, the designated reception channel is changed. That is, in the above example, the reception channel of the broadcast receiver 60-1 is changed from “Bch” to “Cch”. Thereafter, the control unit 20 finishes this process and enters a channel setting signal input waiting state.

一方、今回のチャンネル設定信号を出力したリモコンが前回と異なる場合、例えばリモコン７１の操作により放送受信機６０−１が「Ａｃｈ」を視聴している状態で、優先権を有していないリモコン７２を操作して放送受信機６０−１の受信チャンネルを「Ｃｃｈ」に変更したとする。そうすると、今回のチャンネル設定信号を出力したリモコンが前回と異なるので、上記ステップＳＢ１の判断結果が「ＮＯ」になり、ステップＳＢ３に進む。ステップＳＢ３では、優先権を持つリモコンによるチャンネル変更であるか否かを判断する。上記一例の場合には、優先権を有していないリモコン７２の操作によるチャンネル変更なので、判断結果は「ＮＯ」となり、上述のステップＳＢ２に進み、指示された受信チャンネルに変更した後、本処理を終えてチャンネル設定信号入力待ちの状態となる。 On the other hand, if the remote controller that has output the current channel setting signal is different from the previous one, for example, the remote controller 72 that does not have priority in the state where the broadcast receiver 60-1 is viewing “Ach” by operating the remote controller 71. To change the reception channel of the broadcast receiver 60-1 to “Cch”. Then, since the remote controller that has output the current channel setting signal is different from the previous one, the determination result in step SB1 is “NO”, and the process proceeds to step SB3. In step SB3, it is determined whether or not the channel is changed by a remote controller having priority. In the case of the above example, since the channel is changed by the operation of the remote controller 72 having no priority, the determination result is “NO”, the process proceeds to step SB2 described above, and after changing to the instructed receiving channel, this processing is performed. After completing the above, it enters a channel setting signal input waiting state.

これに対し、例えばリモコン７０〜７２の各操作により各視聴系統（放送受信機６０−１〜６０−３）がそれぞれ「Ａｃｈ」、「Ｂｃｈ」、「Ｃｃｈ」を視聴している状態で、優先権を有するリモコン７０により放送受信機６０−２の受信チャンネルを「Ａｃｈ」に変更するチャンネル設定信号を発生した場合を想定する。この場合、今回のチャンネル設定信号を出力したリモコンが前回と異なる為、上記ステップＳＢ１の判断結果は「ＮＯ」となり、ステップＳＢ３に進み、さらに優先権を持つリモコンの操作によるチャンネル変更であるから、このステップＳＢ３の判断結果が「ＹＥＳ」になり、ステップＳＢ４に進む。 On the other hand, for example, when each viewing system (broadcast receivers 60-1 to 60-3) is viewing “Ach”, “Bch”, and “Cch” by each operation of the remote controllers 70 to 72, priority is given. It is assumed that a channel setting signal for changing the reception channel of the broadcast receiver 60-2 to “Ach” is generated by the authorized remote controller 70. In this case, since the remote controller that has output the channel setting signal this time is different from the previous one, the determination result in step SB1 is “NO”, and the process proceeds to step SB3. The determination result in step SB3 is “YES”, and the process proceeds to step SB4.

そして、ステップＳＢ４では、現在の受信チャンネル番号と、今回のチャンネル設定信号を出力したリモコンのリモコン番号とを含むパケットを形成して通信部６０ｅから無線送信する。上記一例の場合、現在の受信チャンネル「Ｂｃｈ」と、リモコン７０のリモコン番号とを含むパケットを、他の視聴系統（放送受信機６０−１、６０−３）に無線送信する。 In step SB4, a packet including the current reception channel number and the remote control number of the remote controller that has output the current channel setting signal is formed and wirelessly transmitted from the communication unit 60e. In the case of the above example, a packet including the current reception channel “Bch” and the remote control number of the remote controller 70 is wirelessly transmitted to other viewing systems (broadcast receivers 60-1 and 60-3).

次いで、ステップＳＢ５では、受光部６０ａが供給するチャンネル設定信号から抽出した受信チャンネル番号を放送受信部６０ｃに供給して指示された受信チャンネルに変更する。つまり、上記一例の場合には、優先権を有するリモコン７０の操作により放送受信機６０−２の受信チャンネルが「Ｂｃｈ」から「Ａｃｈ」に変更される。この後、制御部２０は本処理を終えてチャンネル設定信号入力待ちの状態となる。 Next, in step SB5, the reception channel number extracted from the channel setting signal supplied by the light receiving unit 60a is supplied to the broadcast receiving unit 60c and changed to the designated reception channel. That is, in the case of the above example, the reception channel of the broadcast receiver 60-2 is changed from “Bch” to “Ach” by operating the remote controller 70 having priority. Thereafter, the control unit 20 finishes this process and enters a channel setting signal input waiting state.

さて、上記ステップＳＢ４において無線送信されたパケットは、他の視聴系統（放送受信機６０−１、６０−３）で受信される。パケットを受信した視聴系統（放送受信機６０−１、６０−３）の制御部６０ｂは、図５に図示するパケット受信処理を実行し、ステップＳＣ１に処理を進める。ステップＳＣ１では、受信したパケットに含まれるリモコン番号と、前述したチャンネル設定レジスタＣＳＲに格納されるリモコン番号とが一致するか、つまり受信したパケットに含まれるリモコン番号が現在の受信チャンネルを設定したリモコンのリモコン番号と同じであるかどうかを判断する。 The packet wirelessly transmitted in step SB4 is received by other viewing systems (broadcast receivers 60-1 and 60-3). The control unit 60b of the viewing system (broadcast receivers 60-1 and 60-3) that has received the packet executes the packet reception process illustrated in FIG. 5, and proceeds to step SC1. In step SC1, the remote control number included in the received packet matches the remote control number stored in the channel setting register CSR described above, that is, the remote control in which the remote control number included in the received packet sets the current reception channel. It is determined whether it is the same as the remote control number.

上記一例の場合、放送受信機６０−３では、受信したパケットに含まれるリモコン番号と、前述したチャンネル設定レジスタＣＳＲに格納されるリモコン番号とが一致しないので、判断結果は「ＮＯ」になり、何も行わずに本処理を終える。したがって、放送受信機６０−３では、チャンネル変更を行わず、「Ｃｃｈ」を視聴している状態を維持する。 In the case of the above example, in the broadcast receiver 60-3, since the remote control number included in the received packet does not match the remote control number stored in the channel setting register CSR described above, the determination result is “NO”. The process ends without doing anything. Therefore, the broadcast receiver 60-3 maintains the state where “Cch” is viewed without changing the channel.

これに対し、放送受信機６０−１では、受信したパケットに含まれるリモコン番号と、前述したチャンネル設定レジスタＣＳＲに格納されるリモコン番号とが一致する為、判断結果は「ＹＥＳ」になり、ステップＳＣ２に進む。ステップＳＣ２では、受信したパケットに含まれる受信チャンネル番号を放送受信部６０ｃに供給して指示された受信チャンネルに変更する。すなわち、上記一例の場合には、放送受信機６０−１の受信チャンネルが「Ａｃｈ」から「Ｂｃｈ」に自動的に変更される。 On the other hand, in the broadcast receiver 60-1, since the remote control number included in the received packet matches the remote control number stored in the channel setting register CSR described above, the determination result is “YES”, and the step Proceed to SC2. In step SC2, the reception channel number included in the received packet is supplied to the broadcast receiving unit 60c and changed to the designated reception channel. That is, in the above example, the reception channel of the broadcast receiver 60-1 is automatically changed from “Ach” to “Bch”.

このように、第２実施形態では、チャンネル変更を指示したリモコンから出力されるチャンネル設定信号（リモコン番号、優先権の有無および受信チャンネル番号）を一時記憶するチャンネル設定レジスタＣＳＲを、各視聴系統（放送受信機６０−１〜６０−３）に設ける。各視聴系統は、チャンネル設定レジスタＣＳＲを参照し、今回のチャンネル設定信号を出力したリモコンが前回と異なり、かつ優先権を持つリモコンの操作によるチャンネル変更であるかどうかを判断する。この条件に合致した場合には、現在の受信チャンネル番号と、今回のチャンネル設定信号を出力したリモコンのリモコン番号とを含むパケットを形成して他の視聴系統に無線送信する。 As described above, in the second embodiment, the channel setting register CSR that temporarily stores the channel setting signal (remote control number, presence / absence of priority and reception channel number) output from the remote controller instructing the channel change is stored in each viewing system ( Provided in the broadcast receivers 60-1 to 60-3). Each viewing system refers to the channel setting register CSR and determines whether or not the remote controller that has output the current channel setting signal is a channel change due to the operation of the remote controller having priority, unlike the previous one. If this condition is met, a packet including the current reception channel number and the remote control number of the remote controller that has output the current channel setting signal is formed and wirelessly transmitted to another viewing system.

このパケットを受信した他の視聴系統では、受信したパケットに含まれるリモコン番号が現在の受信チャンネルを設定したリモコンのリモコン番号と同じであるかどうかを判断し、同じならば受信したパケットに含まれる受信チャンネル番号で指示される受信チャンネルに変更する。この結果、ある視聴系統で受信チャンネルが変更された場合に、その変更以前の受信チャネルを即座に他の視聴系統に設定することが可能になる。 In other viewing systems that have received this packet, it is determined whether or not the remote control number included in the received packet is the same as the remote control number of the remote control that has set the current reception channel. Change to the receive channel indicated by the receive channel number. As a result, when a receiving channel is changed in a certain viewing system, it is possible to immediately set the receiving channel before the change to another viewing system.
