DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast receiving apparatus for receiving, for example, digital television broadcasting and outputting video and audio.

[0002]

2. Description of the Related Art Image compression using digital signal compression technology
There is digital broadcasting that compresses audio signals and broadcasts a stream (transport stream) obtained by time-division multiplexing of video and audio digital signals of a plurality of programs via a transponder (satellite repeater). On the other hand, a broadcast receiving apparatus that receives such a digital multi-channel broadcast selects one of a plurality of transponders of the digital broadcast received through a dedicated antenna by a tuner, and selects a plurality of channels included in the one transponder. One of them is selected by demultiplex processing, and a video / audio signal is output by decoding a digital signal of the selected channel.

[0003] By the way, in such digital television broadcasting, in addition to transmitting video and audio in the same manner as conventional analog broadcasting, service information (program name, program content, program start time, program end time, etc.) is also transmitted. On the broadcast receiver side, an OSD (On Screen Display) function and an EPG (Electronic ProgramGu) are used.
By providing the (ide) function, a program desired by a viewer can be efficiently selected from multi-channel digital broadcasting. Also, by displaying a menu screen on a display by the OSD function,
The user can easily select various functions of the broadcast receiving device while viewing the menu screen.

[0004]

However, although the operability is improved by the screen display function as described above, especially for the elderly, the display characters are difficult to see or the operation method is not understood. For the reason that the above display is easily overlooked, various functions of the broadcast receiving apparatus cannot be sufficiently used.

[0005] In view of the above circumstances, it is an object of the present invention to make it easier to operate a broadcast receiving apparatus, that is, to make it easier for a user to receive information emitted by a broadcast receiving apparatus.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a broadcast receiving apparatus for receiving broadcast waves and outputting video and audio, generates message information and displays a screen. Message screen output means for outputting, message sound output means for outputting a message sound,
Control means for causing the message screen output means to output a message screen and outputting the message sound to the message sound output means in response to an operation of the operation unit by the user. Preferably, the message sound output means comprises a voice synthesis means. Further, the control means determines whether or not there is a failure in performing the operation instructed by the user now or later, and outputs a message screen output to the message screen output means when determining that a failure exists. It is preferable that the message sound output means output the message sound.

In such a configuration, a predetermined message screen and a predetermined message sound are output in response to the operation of the operation unit by the user. For example, when the user performs a mistake operation, a warning sound or a voice message is output together with a message screen such as “Miss operation”. Further, for example, when the user performs a predetermined program reservation operation, a voice message such as “Reservation received” is output together with a message screen “Reservation received”.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to FIG.
4 to FIG. 4, in which the user
(Broadcasting via Satelli
te) A case where digital broadcasting is received is illustrated.

FIG. 1 is a block diagram showing a digital broadcast receiving apparatus 30 of this embodiment for receiving a BS digital broadcast.

[0010] The antenna 1 is arranged outdoors in a predetermined direction, and receives a digital broadcast signal transmitted from the BS. The antenna 1 generally includes a frequency converter, and supplies a received / frequency-converted signal to a tuner 2.

The tuner 2 extracts a signal of a specific frequency from a high-frequency digital modulation signal including video and audio data. That is, a process of selecting one from a plurality of digital broadcast transponders is performed. Further, the tuner 2 includes a demodulation circuit, a deinterleave circuit, an error correction circuit, and the like, and thereby demodulates the selected digital modulation signal and outputs a transport stream.

A demultiplexer (DEMUX) 3 converts the transport stream received from the tuner 2 into an MPEG2 (Moving Picture Ex
parts transport group 2) video transport packet, audio transport packet, and P
SI (Program Specific Information)
mate). The demultiplexer 3 supplies a video transport packet and an audio transport packet to the AV decoder 4, and supplies service information and the like included in the PSI to the system controller 13. As described above, a plurality of channels are multiplexed in the transport stream, and a process for selecting an arbitrary channel from among the channels is performed by the P
This can be achieved by extracting data such as which packet ID a given channel is multiplexed in the transport stream from the SI. Also, the selection of the transport stream (transponder selection) is P
It can be performed based on SI information. Further, the service information includes program information (program contents, program start time,
Program end time, genre information, etc.).

The AV decoder 4 includes a video decoder for decoding video transport packets and an audio decoder for decoding audio transport packets. The video decoder is
The input variable length code is decoded to obtain a quantization coefficient and a motion vector, and inverse DCT transform and motion compensation control based on the motion vector are performed. The audio decoder generates audio data by decoding the input coded signal. The video data generated by the decoding is output to the video processing circuit 5, and the audio data is output to the audio processing circuit 6.

The video processing circuit 5 receives video data from the AV decoder 4 and performs D / A conversion, for example, NTS
Convert to a C format composite signal. The audio signal processing circuit 6 receives the audio data output from the AV decoder 4, performs D / A conversion, and generates, for example, a right (R) sound analog signal and a left (L) sound analog signal.

The video output circuit 7 and the audio output circuit 8 are provided with an output resistor, an amplifier and the like. The AV output terminal 9 is provided with an output unit (a set of left and right audio output terminals and the like and a set of video output terminals). One output unit has a video / audio code 1
A VCR (Video Cassette Recorder) 16 is connected by 7, and a monitor 18 having a picture tube 18 a and a speaker 18 b is connected to another output unit by a video / audio code 19.
Is connected.

The OSD (on-screen display) circuit 12 outputs bitmap data based on character information and color information instructed by the system controller 13 to be output to the adder 20. The adder 20 performs a process of incorporating the bitmap data into a video signal output from the video processing circuit 5. The OSD circuit 12 receives an EPG (Electronic Pr) based on the service information included in the PSI received by the system controller 13.
(Guide Guide) screen display, and various menu screen displays are realized. On the EPG screen or the menu screen, a broadcast program name, a program start / end time, and the like are displayed. Further, the OSD circuit 12 receives from the system controller 13 a character information output instruction such as “operation error” or “accepted” or a color change instruction at a predetermined location, and performs on-screen processing based on the output instruction. .

The speech synthesis circuit 21 has, for example, encoded data obtained by compressing and encoding some words uttered by a human (for example, “operation error” or “accepted”). The coded data is selected based on the message specifying information from 13, the selected coded data is subjected to decoding processing and sound signal conversion (D / A conversion), and output to the sound output circuit 8.

The remote control transmitter 10 is a transmitter for transmitting a command to the broadcast receiving device 30. When a key (not shown) provided on the remote control transmitter 10 is operated, a signal light (remote control signal) indicating a command corresponding to the key is transmitted from a light emitting unit (not shown). The remote control light receiver 11 receives the signal light, converts the light into an electric signal, and supplies the electric signal to the system controller 13.

The system controller 13 performs processing such as receiving a recording reservation by a user using the remote control transmitter 10 or the like. Information obtained by the recording reservation processing or the like is stored in the memory 14A. Also, the system controller 13
Has a function as a message determination unit. That is, the message is determined based on the operation state of the broadcast receiving device 30 or information (operation / operation information) based on a user operation command. For example, when it is determined that the operation command from the user is not executable, a message “operation error” is selected. For this message selection process, the system controller 13 uses, for example, a table in which the above-mentioned operation / operation information is associated with the message. This table is stored in the nonvolatile memory 1
4B. The system controller 13
OSD displays the message selected based on the operation / operation information
Output to the circuit 12 and the speech synthesis circuit 21.

The external device remote control transmitter 15 is provided with the VC
It is a transmitter for sending a command to R16, and outputs a signal light (remote control signal) from a light emitting unit (not shown) based on a control signal output from the system controller 13.
The system controller 13 can execute a command process based on a remote control code in the VCR of each company.
When a command to the VCR 16 is issued, the external device remote control transmitter 15 is driven based on the remote control code used in the VCR 16.

FIG. 2 shows a broadcast receiving apparatus 30, a VCR 16,
FIG. 2 is a perspective view showing the appearance of a monitor 18 and an external device remote controller transmitter 15. The external device remote control transmitter 15 is connected to the broadcast receiving device 30 by wire (or may be wireless). The signal light (remote control signal) emitted from the external device remote control transmitter 15 reaches the light receiving section of the VCR 16. Unlike the remote control transmitter 10, the external device remote control transmitter 15 does not need to be provided with a key or the like.

FIG. 3 is an explanatory diagram showing an example of the remote controller correspondence table of each company described in the instruction manual. For example, VC
If R16 is made by Company A and employs mode 1, the user operates keys "0" and "1" of remote control transmitter 10 in the external device registration mode,
The broadcast receiving apparatus 30 can recognize that the VCR manufactured by Company A is connected and that the mode is set to mode 1.

The system controller 13 writes information (recording reservation program information and the like) input on the EPG screen and various menu screens into the memory 14A. Then, when the start time of the program specified based on the information stored in the memory 14A comes, the tuner 2 performs the tuning process for receiving the program, and outputs the video / audio from the AV output terminal 9 while , The external device remote control transmitter 15 is driven by using the remote control code adopted in the VCR 16, and the VCR 16 records the program.

Further, the system controller 13 executes a message output process as described below. FIG.
(A) shows an example of an EPG screen displayed on the picture tube 18a and a voice message output from the speaker 18b. The user can make a program reservation using the remote control transmitter 10 while watching the EPG screen. When a program reservation operation is performed by the user, the system controller 13 determines whether or not a program reservation has been made repeatedly in the same time zone in light of the already reserved information stored in the memory 14A. When it is determined that there is no overlapping reservation, a color change process is performed on the portion of "Yes" in the figure. That is, color change information indicating that the reservation has been accepted is generated and output to the OSD circuit 12 on the screen. At the same time, the information indicating the voice message "program reservation accepted" is output to the voice synthesis circuit 21, and the voice synthesis circuit 21 outputs the voice message "program reservation received".

On the other hand, if it is determined that the reservation is a duplicate reservation, the contents of the program reservation are displayed as shown in FIG. 4 (b), and "a plurality of programs are reserved at the same time. Please set again." Generates character information of OSD
The screen is output by the circuit 12. At the same time, information indicating a warning sound (message sound) of "Bibi" and a voice message of "Reserving a plurality of programs at the same time, please set again" is output to the voice synthesis circuit 21.
The voice synthesizing circuit 21 outputs a voice message.

FIG. 5 is a flowchart showing an example of a message output process. First, it is determined whether or not an operation (remote control operation or the like) has been performed by the user (step S1). If the user has performed an operation, it is determined whether or not an operation error has occurred (step S2). If the operation is not an error, a process corresponding to the remote control operation is executed (step S4), and the process returns. On the other hand, if the operation is incorrect, the content of the error is displayed by the OSD circuit 12, and at the same time, a voice message is output by the voice synthesizing circuit 21 (step S3).

In the above-described example, the message output accompanying the program reservation recording operation has been described. However, the present invention is not limited to this, and the message output can be performed for various operations. Further, as for the voice message, a mode in which both the message sound and the voice message are output has been described, but the present invention is not limited to this, and a mode in which only one is output may be adopted. When outputting only the message sound, the voice synthesis circuit 21 is not required, and a simple sound generation circuit may be provided. Further, a message may be output when an emergency broadcast is received. Also, the case where digital broadcasting is viewed has been described as an example. However, the present invention is not limited to this, and the present invention can be applied to the case where analog broadcasting is viewed.

[0028]

As described above, according to the present invention, a message is displayed on a screen and a sound or voice message is output in response to a user's operation of a remote controller or the like. Can be easily transmitted to the user, and even an unfamiliar person can use the broadcast receiving device comfortably.
