At this time, a bit stream is generated by performing time division multiplexing processing on each of the audio encoded data supplied from the audio encoder 21 and the video encoded data supplied from the video encoder 22. The bit stream is scrambled, and the resulting multiplexed data D30 is output to the modulator 24.
Therefore, as a result, the transmission device 15 distributes the broadcast wave on which the EPG data is superimposed to the IRD 3.

In this case, the front end 30 of the IRD 3 (FIG. 4) extracts the broadcast wave of the channel on which the EPG data is superimposed from the received broadcast wave, and demodulates the broadcast wave of the extracted channel. To generate the multiplexed data D30 and send it to the demultiplexer 31.

The demultiplexer 31 outputs the multiplexed data D
30 is temporarily stored in a buffer (not shown), and the stored multiplexed data D30 is transmitted in advance using the descrambling key data owned by the IRD 3 (FIG. 3).
After the scramble performed in step (1) is released, the EPG data D25 is transferred to the flash memory 41 via the bus BUS and stored therein by appropriately reading the scramble.

As described above, the IRD 3 (FIG. 4) periodically updates the EPG data stored in the flash memory 41 and always stores the latest EPG data in the flash memory 41. .

In this state, when the user is watching a desired television program (referred to as a music program) via the display screen of the monitor 12 (FIG. 2) of the television apparatus 11, for example, C of the song being sung
If the user wants to obtain detailed information about the music, such as calling for a D (Compact Disk) or calling for singing karaoke of the song, the user needs to insert the removable medium 5 owned by himself into the slot provided in the IRD 3. It is made to be attached to.

As shown in FIG. 14, the removable medium 5 is inserted into a slot of each terminal device (FIG. 1: IRD 3, personal computer 6, mobile phone 7, PDA 8 and navigation device 9, FIG. 2: karaoke device 18). 5A, and a memory 5B connected to the connector 5A via a bus BUS.

When the removable medium 5 is the IRD 3
(FIG. 4), when the detection contact of the removable medium 5 is connected to the contact of the removable media interface 43 in the IRD 3, the interface processing unit 44 changes the signal level for detection of the removable medium (see FIG. 4). A change from a logic "L" level to a logic "H" level) is detected, and an interrupt signal is sent to the CPU 36 to perform interrupt processing. Thereby, the CPU 36 detects that the removable medium 5 is mounted.

The interface processing unit 44 transmits and receives data to and from the removable medium 5.
This is a processing block for performing protocol processing according to the interface specifications. As a result, the interface processing unit 44 enters a state in which additional information serving as user-specific information can be written to the removable medium 5.

The removable media interface 43 is constituted by a serial interface and has at least three data lines. The first data line transmits a clock signal during data transmission, the second data line transmits a status signal required during data transmission, and the third data line transmits data written to or read from the removable medium 5. Transmit serially.

In a state where the removable medium 5 is mounted in the slot of the IRD 3 (the CPU 36 detects that the removable medium 5 is mounted), the user uses the remote controller 29 to perform a predetermined additional information acquisition operation. Then, the remote controller 29 generates a command signal S1 corresponding to the operation, and superimposes the generated command signal S1 on infrared rays and transmits the signal to the IRD 3.

When the IRD 3 receives the command signal S1 superimposed on the infrared ray and transmitted by the infrared ray receiving section 28, the infrared ray receiving section 28 performs a photoelectric conversion on the received infrared ray to thereby superimpose it on the infrared ray. The command signal S1 is extracted and sent to the CPU 36.

Thus, the CPU 36 as a selecting means
Is the Event-ID corresponding to the music program selected by the IRD 3 (displayed on the monitor by the user) at this time.
All of the additional information existing in the lower hierarchy of the
Dictionary data such as characters and symbols stored in the RAM 3
9 on the RAM 39, and performs graphic processing on all the additional information read out at this time based on the dictionary data.
5 is generated and sent to the graphic engine 40.

The graphic engine 40 performs a digital-to-analog conversion process on the additional information selection screen data D45, and further converts it into an NTSC-type luminance signal and color difference signal to generate an additional information selection image signal S46. It is sent to the RGB encoder 35.

The RGB encoder 35 outputs the additional information selection image signal S 46 supplied from the graphic engine 40.
And a video signal supplied from the video decoder 33 at this time.
(FIG. 2), the television apparatus 11 displays on the monitor 12 (FIG. 2) an image corresponding to the mixed signal S46 and an additional information selection screen as shown in FIG. 15, for example. Prompt.

The user responds to the additional information selection screen displayed at this time by using the remote controller 29.
When a desired number is input and a predetermined acquisition operation (operation for acquiring the additional information provided by the communication karaoke company 17) is performed, the remote controller 29 generates a command signal S1 corresponding to the operation and generates the command signal S1. The command signal S1 is superimposed on infrared rays and transmitted to the IRD3.

When the IRD 3 receives the command signal S1 superimposed on the infrared ray and transmitted by the infrared ray receiving section 28, the infrared ray receiving section 28 performs photoelectric conversion on the received infrared ray to thereby superimpose it on the infrared ray. The command signal S1 is extracted and sent to the CPU 36.

Thus, the CPU 36 as a selecting means
Sends the additional information corresponding to the number input (selected) by the user among the additional information developed on the RAM 39 at this time to the filter unit 42.

The filter section 42 filters (rewrites or deletes) each additional information based on the registration information registered in the flash memory 41 of the IRD 3 in advance.

Here, the registration information is information for registering various terminal devices owned by the user in the IRD 3 or various terminal devices desired to be used as an identification code, and the identification code is a flash memory in the IRD 3. 4
1 is stored. The identification code has a combination corresponding to the identification code of Target device information (FIG. 6), which is an item of additional information, and is read out by the CPU 36 when the removable medium 5 is mounted.

In this registration information registration method, when the user purchases the IRD 3, the remote controller 29
When a predetermined initial registration operation is performed using
For example, a registration screen as shown in FIG. 17 is displayed to prompt the user to register. On the other hand, the user performs a predetermined registration operation using the remote controller 29 on the registration screen to register. The registered content registered at this time is the CPU
36 is reflected in the identification code of the registration information. That is, the identification code of the registration information represents various terminal devices used by the user or a combination of various terminal devices desired to be used.

Incidentally, the IRD 3 is designed to rewrite the registration information again. In this case, for example, when the user purchases a new terminal device and performs a predetermined re-registration operation using the remote controller 29, the CPU 36
Displays a registration screen as shown in FIG. 17 again, and prompts the user to register again. On the other hand, the user performs a predetermined registration operation using the remote controller 29 on the registration screen to register again. The registration contents registered at this time are reflected by the CPU 36 on the identification code of the registration information.

In a state where the additional information corresponding to the number input (selected) by the user is transmitted from the RAM 39 to the filter unit 42 as the recording means, the filter unit 42 transmits the additional information supplied from the RAM 39 at this time. An identification code (combination) of each Target device information and registration information (a personal computer 6, a mobile phone 7, a PDA 8 and a navigation device 9 as devices owned by the user, and a karaoke device as a terminal device desired by the user) The identification code of each Target device information is rewritten so that both the combination with the identification code (combination) of (18) is the same.

That is, the filter unit 42 outputs a Tar table representing a combination of terminal devices that the information providing advertiser wants to use.
Both the identification code of the get device information and the identification code of the registration information indicating the combination of the terminal devices used by the user match (the terminal device desired by the information providing advertiser and the terminal device used by the user). By rewriting the identification code of the target device information so as to be a combination, the rewritten identification code of the target device information is the terminal device that the information providing advertiser wants to use among the terminal devices that the user can use. It consists of a combination of devices.

That is, for example, the access information (eg, “http: // www. !!!!! .co.”) Of the additional information access item (eg, “URL” item, “position” item)
jp "," N: 38 ° 24'15 "/ S: 138 ° 2
By describing 3'53 "", a personal computer and a navigation device (that is, a personal computer as a terminal device that an information providing advertiser wants to use) can be handled as a terminal device that can be handled represented by the identification code of Target device information. And the navigation device is represented), and only the personal computer (that is, the terminal device possessed by the user is the only personal computer) as the treatable terminal device represented by the identification code of the registration information, The filter unit 42 rewrites the identification code of the Target device information to an identification code that can be handled only by the personal computer (that is, a combination of terminal devices that the user can use among the terminal devices that the information providing advertiser wants to use).

Further, the filter unit 42 determines whether or not the time limit described in the validity period of the additional information has passed based on the clock in the IRD 3 in advance. If the described time limit has passed, the additional information is filtered (deleted).

When the identification code of the Target device information is rewritten, the filter unit 42 stores the rewritten additional information in the memory 5B of the removable medium 5 via the removable medium interface 43 and the connector 5A (at this time, It is assumed that the additional information provided by the communication karaoke company 17 is also stored).

Here, the filter section 42 as recording means
When the additional information is stored in the removable medium 5, the identification code of the Target device information of the additional information is set to be used by either the karaoke device or the navigation device, or by both the karaoke device and the navigation device. A predetermined editing file stored in advance in the flash memory 41 is read out, and this is also read from the removable media interface 43.
