The video signal is displayed on the display 201 and the audio signal is output from the speaker 202.

  Through the above operation, channel selection and program channel switching can be performed by transmitting / notifying the broadcast receiving apparatus 100 of information on the remote control code of the channel switching operation by the user operating the remote control means 111.

  Next, an operation when the broadcast receiving apparatus 100 is installed will be described. When receiving a broadcast by radio wave via an antenna when receiving a broadcast from a broadcast station, or receiving a broadcast via an IP network, the broadcast station selection, remote control button channel number setting, etc. It is necessary to perform the initial setting when the receiving apparatus 100 is installed. Items that need to be initialized include 1) initial setting of the channel selection frequency and 2) correspondence setting of the remote control channel.

  In terrestrial broadcasting using radio waves, broadcast stations that can be received for each area where the broadcast receiving apparatus 100 is installed and the transmission frequency of the broadcast station are determined as area information. For this purpose, the area information is obtained from information necessary for position search such as a telephone number or a postal code. As one of the initial setting methods, there is a method of setting the area information obtained by the user by using a menu screen or an initial setting screen in the broadcast receiving apparatus 100 to input.

  The frequency for selecting from the area information set in this way, the information for designating (selecting) the broadcast program of the corresponding broadcast station from the transmission stream transmitted via the network, etc. are selected. Store / manage in the station information storage means 108, and store / manage correspondence between information for selecting a broadcast program in the tuning information storage means 108 and a remote control code generated when the user operates the remote control means 111 To do.

  When the settings as described above are made, the automatic channel selection control unit 110 receives data based on the frequency information of each broadcasting station based on the channel selection information for frequency selection stored in the channel selection information storage unit 108. The reception control means 109 is controlled so that the control means 109 controls the channel selection front end means 102 to sequentially select broadcast stations.

  When selecting a broadcasting station, the reception state determining unit 119 performs the channel selection front end every time the channel selection front end unit 102 sequentially selects a channel based on the stored information stored in the channel selection information storage unit 108. The demodulation state in the demodulation means 115 constituting the means 102 is detected, and the detected demodulation state is notified to the channel selection setting determination means 107 via the channel selection information acquisition means 116.

  On the other hand, in broadcasting received via an IP network, a user obtains information necessary for channel setting that can be received in each area online via the IP network, or other information related to, for example, own channel selection. Obtained by collecting information.

  The information necessary for channel setting acquired in this way is input from the remote control unit 111 to the broadcast receiving apparatus 100 by the user, and is selected through the remote control receiving unit 112, the reevaluation setting unit 113, and the channel selection setting determining unit 107. Stored / managed in the information storage means 108. Further, in the channel selection information storage means 108, information necessary for channel setting, that is, information for selecting a broadcast program and a remote control code transmitted from the remote control means 111 to the broadcast receiving apparatus 100 by a user operation are stored. And information for identifying which one of the broadcasts using radio waves and the broadcast via the broadband network is to be stored / managed.

  When the above settings are made, the automatic tuning control means 110 selects the reception control means 109 based on the tuning information of each broadcasting station based on the tuning information stored in the tuning information storage means 108. The reception control means 109 is controlled so that the station front end means 114 is controlled to sequentially select each broadcasting station.

  When selecting a broadcasting station, the transmission state determination unit 120 selects the channel selection front end each time the channel selection front end unit 114 sequentially selects a channel based on the stored information stored in the channel selection information storage unit 108. The state of transmission in the communication control means 117 constituting the means 114 is detected, and the detected transmission state is notified to the channel selection setting judgment means 107 via the communication control means 117 and the channel selection information acquisition means 118.

  In the broadcast receiving apparatus 100 that has been initially set as described above, the user performs a channel selection operation on the remote control means 111, whereby the remote control code transmitted from the remote control means 111 by the broadcast receiving apparatus 100 is received by the remote control receiving means 112. The broadcast station for broadcasting by radio waves corresponding to the received remote control code or the broadcasting station for broadcasting by the IP network is selected, so that the program channel to be viewed or the program channel to be viewed can be switched.

  However, the reception status of video / audio / data multiplexed streams of broadcast signals received from broadcast stations selected from broadcast stations connected via an IP network in radio broadcasts is always the same quality. Not necessarily.

  In the case of a broadcasting station for broadcasting by radio waves, the reception state in the broadcast receiving device 100 deteriorates due to weather or the generation of a new noise source between the receiving equipment and the receiving antenna, and the reception quality of the video / audio / data multiplexed stream deteriorates. The video quality may deteriorate. As for this deterioration state, the reception state determination unit 119 detects the demodulation state in the demodulation unit 115 constituting the channel selection front end 102, and the detected demodulation state is detected by the channel selection information acquisition unit 116 and the channel setting setting determination unit 107. And stored in the channel selection information storage means 108.

  In addition, a video / audio / data multiplexed stream received from a broadcasting station selected from broadcasting stations connected via an IP network may be deteriorated depending on a transmission state / transmission environment in the IP network. The state of transmission quality deterioration due to such a transmission state / transmission environment is detected by the transmission state judgment unit 120 detecting the transmission state in the communication control unit 117 constituting the channel selection front-end unit 114, and the detected transmission state. It is stored and managed in the channel selection information storage unit 108 via the channel selection information acquisition unit 118 and the channel selection setting determination unit 107.

  As described above, the user operates the remote control unit 111 in the situation where the reception state or transmission state from each broadcasting station in the broadcast receiving apparatus 100 is stored / managed for each broadcasting station in the tuning information storage unit 108. When selecting a channel, i.e., selecting a program, the remote control receiving means 112 receives a remote control code corresponding to this channel selection (program selection) and transmits it to the re-evaluation setting means 113 to re-evaluate the setting means. 113 notifies the channel selection setting unit 107 of the re-evaluation based on the remote control code transmitted from the remote control reception unit 112, so that the information stored / managed in the channel selection information storage unit 108, that is, the broadcast to be selected The broadcast station to be selected can be switched based on the information regarding the reception state or transmission state of the station. For example, even if the program selected by the user is a program of a broadcast station (tentatively referred to as broadcast station C) broadcast by radio waves, the reception state of the broadcast station C is bad, and the same program as the broadcast station C is broadcast. When the transmission quality of the broadcasting station c in the broadcasting using the IP network is good, the broadcasting station to be selected can be automatically switched from the broadcasting station C to the broadcasting station c.

  In this case, since the user performs a normal program channel switching operation or a program channel selection operation, the user does not feel uncomfortable with the change in the screen display that accompanies the switching, and is aware of the channel selection switching. Nor. In addition, since automatic switching (tuning switching) of broadcasting stations based on reception quality is performed at the timing when a user performs a program channel switching operation or a program channel selection operation, Channel selection can be switched without feeling disturbed.

  In Embodiment 1 of the present invention, when the user is performing an operation of switching the program channel for channel selection, the quality of the selected program channel in the reception status or transmission status is judged, that is, reevaluation is performed. However, the present invention is not limited to this. For example, when the user does not view the program, such as when the broadcast receiving device 100 is turned on, By re-evaluating the reception status and transmission status of each broadcasting station and storing / managing the result in the channel selection information storage means 108, the same effect can be obtained.

  In the first embodiment of the present invention, the remote control unit 111 is described as an external accessory device of the broadcast receiving apparatus 100. However, the present invention is not limited to this. For example, all or a part of the functions of the remote control unit 111 are used. May be built in the broadcast receiving apparatus 100.

  As described above, video quality and audio quality can be dealt with by automatically switching between broadcast stations using radio waves and IP networks based on reception quality or transmission quality in response to degradation of reception quality or transmission quality. Can be viewed by the user in the best possible state.

  Further, the broadcast receiving apparatus of the present invention is configured to detect the channel selection timing by the user's remote control and automatically switch the broadcast station at the channel selection timing, so that the user feels uncomfortable / uncomfortable. Broadcast stations can be automatically switched (channel selection) without giving. In addition, when the broadcasting receiver is turned on, the reception status and transmission status of each broadcasting station are evaluated, and the channel selection information in the optimum state is associated with the remote control code, so that the user can always broadcast in a high quality state. Can be watched.
