And at least 10 rows × 20 columns (20 rows) on the television screen 15W of the television receiver 15.
The character information S1 or S2 of the digital recording medium is displayed according to a predetermined search format with a character arrangement of 0 characters or more, and the receiver 10 is controlled to control the digital information of the digital recording medium accommodated in the reproducing apparatuses 1 and 2. The system configuration is such that search and selection of character information S1 and S2 of CD and MD are performed while watching the character display on the television screen 15W.

Further, in addition to the above configuration, the receiver 10
Uses the television screen 15W as a screen keyboard, selects characters while watching the television screen 15W with a cursor key of a remote control device (not shown) of the receiver 10, and inputs characters to the memory devices 3, 4 of the playback devices 1, 2. As described above, the CPU (Central Information Processing Unit) 7 sends a command for writing character information to the playback devices 1 and 2 through the asynchronous bidirectional communication lines L1 and L2, and the CP of the playback devices 1 and 2
U (central information processing devices) 8 and 9 are memory devices 3 and 4
Or a writable digital recording medium (typically MD)
It controls to write the character information S2 to itself.

Incidentally, as the memory device 6 in the receiver 10, a RAM built in the CPU 7 is actually used.

After all, in the present system 30, the receiver 10 as one master device is composed of a plurality of slave devices such as the playback device 1 (CD player) and the playback device 2 (M
D deck) so that a digital recording medium can be searched and characters can be easily input while looking at the character information displayed on the television screen 15W.

The asynchronous bidirectional communication lines L1, L2
L2 and the bidirectional device control communication lines L3 and L4 are both cables consisting of a ground line and a character information communication line or a device control communication line (note that L1 and L3 and L2 and L4 are combined into one cable). Device control communication line L
The communication performed in L3 and L4 is used for a command to the reproduction apparatus such as reproduction or stop, or to obtain device state information from the reproduction apparatus. All commands related to reading / writing of character information are performed on the asynchronous bidirectional communication lines L1 and L2, and the data transmission / reception is the same as that of the conventional asynchronous bidirectional communication.

In the present invention, since a general-purpose cable can be used for the communication line between the devices as described above, it is more cost-effective than using a display screen of a personal computer. This is convenient because complicated operations such as activation are unnecessary. In other words, the use of a television screen, which has an overwhelmingly high penetration rate, is far more versatile than the use of a personal computer screen.

Hereinafter, an example of displaying character information on the television screen will be described with reference to FIG.

As described above, in the present system, by displaying the disc information and the track (song) information on the same screen on the television screen of the character display of 12 rows × 24 columns, the user can easily perform complicated operations without repeating the work. You can quickly search for the desired track without erroneous operation. The above 12
The character arrangement of rows × 24 columns is one example, and in the prototype of the inventor, if there is at least a character arrangement of 10 rows × 20 columns, the above-described easiness of retrieval is realized. Of course, the character arrangement more than the above example may be realized by improving the performance of the CPU 7.

Next, as a method of inputting characters, conventionally, a method of sequentially selecting uppercase letters (27 letters), lowercase letters (27 letters), numbers (10 letters), and symbols (about 20 letters) in order is used. However, in the present invention, FIG.
As shown in FIG. 4 and FIG. 4, a screen keyboard is configured using a television screen, and characters are selected while watching the television screen by a simple operation of a cursor key (right, left, up, down direction button) of a remote control device of the receiver 10. I do.
It will be clear that character input can be performed easily and reliably.

Next, in the present system 30, in particular, the reproducing apparatus 1 is a plural-panel reproducing apparatus (so-called CD changer) for a compact disk of a digital recording medium, and the receiver 10 is written in the memory device 3 of the reproducing apparatus 1. The CD text information of all the compact discs read out is written to its own memory device 6 and the CD
A search unit is provided for selecting and searching one of three items, a performer (performer) name, a disc title name, and a genre name included in the text information.

For example, as can be seen from the search method selection screen shown in FIG. 5, in order to search for one CD from a CD changer (containing 200 CDs), a PERFORMER (performer) ), Disc title (album name), and genre.

As shown in FIG. 5, if the search method is selected from the performers, as shown in FIG.
A character (FIRST CHARACTER) is input with a cursor from a screen keyboard.

When the search method is selected from the disc name as shown in FIG. 7, the first character of the disc name is input in the same manner.

When a method of searching from a genre is selected as shown in FIG. 8, one of the displayed five genre displays (if there is no display, scroll up and down) is selected.

The genre is CD text information.

FIG. 9 is a screen display example of search results when the above-mentioned player search method is selected and "A" is input as the first character. A list of performers can be displayed, and the disc name can be displayed by mode switching. At this time, the information of a plurality of discs is displayed on one screen, so that the search efficiency can be greatly improved for a screen in which only one disc information is displayed on one screen. By moving the cursor to select a desired disc and pressing the SET key, the reproduction of the disc can be started.

When searching by disc name or genre, a list of disc names is first displayed, and the player name can be displayed by mode switching.

As described above, several hundred CDs having a storage capacity
In general, it is not easy for a changer to search for a desired disk, but conventional playback devices have a function of searching from a list of disk names, but searching for a number exceeding 100 requires time. It was done. In the present invention, since the user selects a search method arbitrarily from among three types of search methods and performs a search while watching the television screen, the range of search choices is widened, and the user can easily search for a desired disc in a short time. It is possible to search by.

As a precautionary note, in the conventional AV equipment, several types of digital recording medium reproducing devices are included in the system, and all of these search and character input operations are displayed on a television screen. The idea of using it as a device had not yet been born.

[0069]
