Definitions

  • the present application relates to a device and to a method of operating the device, for storing and displaying text information relating to the content of the information stored on a digital recording medium.
  • the invention is particularly suitable for application to any pre-recorded digital recording medium which cannot be subsequently altered or amended by the user, such as compact discs, laser discs and pre-recorded digital magnetic cassettes or discs.
  • the conventional digital magnetic cassette or compact disc player is either not able to display any data relating to the content of the cassette or disc or is only able to display very limited information such as the number of different items recorded and their length of duration.
  • Such a system is known from EP-A-0 029 946. As shown in Fig. 1, information is read from a magnetic tape (100) by a head (110) and is transmitted to a memory (T) via a buffer memory
  • the information which is read normally consists of a playing time and a track number and a display may be provided for continuously displaying information contained in the buffer memory.
  • a further disadvantage with present systems in which only the track number and duration is displayed is that the user must first consult the cover or casing of the recording medium or consult a separate pamphlet in order to determine which title is located at a particular track position.
  • the sequence of items to be played can be pre-programmed, it is therefore necessary for the user to set up the programme based on the number of the track and not upon the title of the piece to be played.
  • pre-programming the sequence to be played can be a lengthy procedure.
  • the object of the present invention is therefore to provide a system which is capable of storing and displaying Bibliographical data relating to recorded information on a recording medium.
  • a further object of the present invention is to provide a system in which existing recording media may be used as well as recording media in which the Bibliographical data is already pre-recorded.
  • a further object of the present invention is to provide a system in which the pre-recorded item may be searched not only by its sequence number on the recording medium but also by its title.
  • a further object of the present invention is to provide a system with which Bibliographical data relating to the library of recording media can be printed out and updated.
  • an audio, video or audio-video digital system including tracking reading means for reading first digital data stored on a selected track of a recording maximrn and for outputting said first digital data as a digital signal; memory means for storing second digital data, said memory means being non volatile memory means; encoding means operatively connected to said tracking and reading means for encoding a part of the first digital data and read/write means for reading said second digital from a memory address location in said memory means c h a r a c t e r i z e d by said encoding means including means for generating a memory address signal determined from said encoded first digital data, said memory address signal determining the said memory address location.
  • the objects of the invention are also solved by a method of operating an audio/digital reproduction system, in particular, an audio, video or audio-video digital system, including non-volatile memory means, comprising: reading first digital data from a selected track of a recording medium; encoding said first digital data to form a memory address signal; reading second digital data stored in said memory, at a memory address location determined by said address signal.

  • the pick-up (4) is arranged to read the data recorded on the compact disc (3) in the conventional manner.
  • the data from the pick-up (4) is transmitted to the digital analogue converter (7) and the analogue music signal is then transmitted to amplifiers/loudspeakers via the analogue bus (8).
  • the data read by the pick-up (4) is also supplied to the central processor (11) which is linked to a memory (12).
  • the memory (12) includes a non-volatile memory for storing the Bibliographical data as well as programming data.
  • the non-volatile memory may also be constituted by a separate floppy disc or hard disc unit.
  • Data can also be input to the central processor (11) via an inputting device (10) which may be a keyboard or any similar device such as a bar code reader for reading information printed in the form of a bar code on the casing of the respective compact disc.
  • the central processor (11) can also output data to a display (9) or via an RF output (16) to a TV monitor (17) or via a serial output (13) to a printing device (14).
  • the output of the central processing unit (11) may be output to a voice synthesizer (18) whose output is connected either to the digital bus (5) or the analogue bus (8) so that the data from the central processing unit is converted into audible speech.
  • the central processor (11) controls the operation of all these peripheral devices based on pre-programmed instructions.
  • the above described audio digital system operates in three different modes:
  • the pick-up (4) reads N bytes of information from the disc (3). These N bytes are then processed in the central processing unit (11) which contains means for calculating in accordance with a particular algorithm.
  • This algorithm is constructed in such a way that starting from the N bytes read from the disc and operating on them with a sequence of shifts and boolean operations, a data code (C) is calculated that is unique for each disc or item on each disc.
  • the code (C) is then processed through means for generating an address code according to an addressing algorithm (hash table or equivalent) to determine an address code (A) in the memory where the Bibliographical information relating to the disc or to the item on a disc currently being played can be found.
  • the N bytes of information read from the disc can be specially pre-recorded information on the disc. Alternatively, the information can be N bytes read directly from the digitally recorded information on the disc, for example, the first N bytes of the recording.
  • the CPU finds that the location 24 has been already occupied by
  • Data In this case the information of D . is written in the next available address of the free list (A 1000) which is stored in a register NAFL and that address is written at AFL (24);
  • NAFL is a register containing the next free list address available.
  • the information relating to the disc currently being played is read from the memory by read/write means and is output to the display (9), the televis on monitor (17), the printer (14) or the voice synthesizer (18).
  • the memory (12) may not contain the relevant information. This information is stored in the memory during the learn mode.
  • the appropriate N bytes of information are read from the disc and by using the same algorithms, methods and system elements described under the search mode, the address location in the memory (12) is determined for the particular disc.
  • the flow chart for this procedure is shown in Fig. 6.
  • the Bibliographical information can be entered via the input device (10) which may be a keyboard.
  • the Bibliographical information may be stored on the casing of the disc in the form of a bar code.
  • the input device (10) is a bar code reader.
  • (12) may be made directly from the disc itself by further reading of data from the disc (3) using the pick-up (4) as controlled by the control system (6).
  • the general catalogue disc may contain all information relating to all discs supplied by a particular manufacturer or all discs available on the market.
  • the general catalogue disc may contain information relating to the organization of the information of the memory (12) as will be described later,
  • the information stored in the memory (12) can be printed out via the printer (14).
  • the printer (14) In order to allow the report to be sorted by title or by author, by category, by inventory location or by any other means, it is necessary that the text can be retrieved not only by using the data code but also through a multiple set of pointers linking the data in different ways.
  • the general catalogue disc may be organized in the same way.
  • Fig. 3 a possible organization of the information in the memory (12) is shown. For each set of Bibliographical information, a series of pointers is specified, each pointer relating to a particular search mode.
  • the second pointer A2 would then be located at the next author determined alphabetically.

Abstract

Un système de reproduction numérique et notamment un système numérique audio, vidéo ou audio-vidéo comprend un moyen de suivi de lecture (2, 4, 6) destiné à lire des premières données numériques enregistrées sur un support d'enregistrement (3), une mémoire (12) destinée à stocker des secondes données numériques, un codeur (11) destiné à coder une partie des données numériques lues par le moyen de suivi et de lecture (2, 4, 6) ainsi que des moyens d'affichage (9; 14; 17; 18) destinés à afficher les secondes données numériques lues à partir de la mémoire (12). L'adresse dans la mémoire (12) des secondes données numériques associées aux premières données numériques est déterminée par codage d'une partie des premières données numériques lues par le moyen d'enregistrement. Ainsi, il est possible d'accéder aux données bibliographiques stockées dans la mémoire (12) et de les afficher d'après la partie correspondante d'informations pré-enregistrée sur le support d'enregistrement. Les secondes données numériques peuvent être introduites dans la mémoire à l'aide d'un clavier (10) où elles peuvent être lues directement à partir du support d'enregistrement (3) ou à partir d'un autre support d'enregistrement (3) servant de catalogue général. Le système peut être commandé par une unité centrale (11).
