Description

i METHOD OF TRANSFER OF INFORMATION, CARRIER OF INFORMATION, SETTLEMENT TO TRANSMIT AND ARRANGEMENT TO RECEIVE INFORMATION. The invention relates to a method of transferring information by an information signal representing organized information in one or more information structures, in which the information signal is subdivided into blocks and in which the information signal contains data of application related to information. The invention furthermore relates to an information carrier in which an information signal representing information organized in one or more information structures is recorded, in which the information signal is subdivided into blocks and in which the information signal is divided into blocks. Information signal contains application data related to the information. The invention also refers to an arrangement for transmitting and an arrangement for receiving information, both to be used in the method. Such a method and information carrier are employed in the known CD-ROM system which is described in detail in Standard ECMA-130, Data Exchange on 120-mm Read Only Discs. In the known method, the information signal representing the information, i.e., audio information or digital data, is recorded in the known information carrier, the Compact Disc. An apparatus reads the information signal from the information carrier and retrieves the information for a destination. When the invention relates to a method of transferring information by an information signal representing the information organized in one or more information structures, in which the information signal is subdivided into blocks and in which the information signal contains application data related to the information. The invention furthermore relates to an information carrier in which an information signal representing the information organized in one or more information structures is recorded, in which the information signal is subdivided into blocks and in which The information signal contains application data related to the information. The invention also relates to an arrangement for transmit and an arrangement to receive information, both to be used in the method. '- "Such a method and information carrier are used in the well-known CD-ROM system which is described in detail in Standard ECMA-130, Data Exchange in 120-mm Read Only Disks In the known method the signal of information representing the information, ie, audio information or digital data, are recorded in the known information carrier, the Compact Disc.An apparatus reads the information signal from the information carrier and retrieves the information for a When the digital data is transferred, the information signal is subdivided into blocks.In addition to the information, the data thus defined, application data can be transferred by subcode channels on the CD-ROM. information related to audio information or digital data, such as subdivision in tracks, operating time, or catalog number .A condition of the known method is to quel for the information process, the information structure will be known at the end of destination. It is impossible to determine the information structure of the transferred information in a simple way. In addition, subcode channels are less suitable for transferring application data due to the difference in signal processing. It is an object of the invention, for example, to provide mechanisms by which information and application data can be transferred to a destination without the need to know the structure of the information. in advance. According to this first aspect of the invention, a method of the type defined in the introduction paragraph is characterized in that the application data is contained in blocks and that each block contains a code of application that is indicative of the structure of the information, while the structure of the application data depends on the application code. The invention is advantageous because the structure of the information of each block is known without the need to analyze in other information present from the blocks having a different information structure and without the need to store the result in a memory. It should be noted that the control field of the q-channel of the CD-ROM subcode carries application data reigated with the audio mode, such as the number of channels and pre-emphasis or no pre-emphasis. A determined value that indicates that the digital data is present. This value is thus adhered to in the case of the CD-ROM (ECMA-130, by 22.3.1), but in reality it only indicates that there is no audio information and that there is a transparent digital transfer channel. In the case of CD-ROM, this channel is used in the known way, in which the information signal is subdivided into blocks. Each block contains a mode indicator which indicates either one of the two possible error correction systems, or an empty block. Such mode indicator is not considered an application code, because this mode indicator does not relate in any way to the information structure of the information transferred, but only concerns the parameters of the information transfer channel.

A destination does not have the fix of this mode indicator and therefore can not derive anything about the structure of the information from this mode indicator. The invention is further advantageous in that the application data becomes simultaneously available with the information to which they are related. The invention also has another advantage, that the information density during the transfer of information can be high, because the manner in which the symbols represent the information can be chosen with minimal redundancy for each information structure. The invention has a further advantage, that the density of the information of the application data can be high, because the manner in which the symbols represent the application data, can be chosen with a minimum redundancy for each information structure. . In addition, the invention is advantageous because it is possible to transfer information having different information structures for different destinations, or in which the destination can select the information designated for this destination from the information flow supplied. Furthermore, the invention is advantageous because if the blocks have been lost during the transfer of the information, the information structure of each block is known immediately after the information transfer has finished. Another advantage of the invention is that without any modification of the arrangement, the method may be appropriate for transferring information having new information structures that have not yet been established. It is impossible to design a universal information structure that includes all the desired applications known at a given time and that, additionally, is appropriate for the extension of future applications. A method or carrier of information, for which the information is contained in a stream of the universal structure, for example, digits, symbols, can not be arranged for such a universal information structure. However, such a method or information carrier can be universal, if the information structure can be recognized distinctly from the block itself, whose block is the smallest significant group of symbols. The information of a new information structure can then be transferred alternately with previously determined information structures. An embodiment for the method in which the information structure comprises one or more substructures is characterized in that the substructure in each block depends on the application data. This incorporation is advantageous in that the information density is very high, since the way in which the symbols represent the information, can be chosen with minimal redundancy for each substructure of an information structure. At the point of destination, the information process can be simply tuned to a particular substructure. Another embodiment for the method, in which the information signal is subdivided into groups and a group contains a plurality of blocks, is characterized in that the group contains a group application code that relates to all the blocks of that group in particular. This incorporation is advantageous in that the array knows the group application code, the information structure for a period of time and does not need to analyze the application code of each block. Another embodiment for the method characterized in the group application code is equal to the application code of each of the blocks in that particular group, and has a predetermined value if the blocks in the group have different application codes. This incorporation is advantageous in that the array can derive from the group application code if the application code will vary in the blocks considered. Another embodiment for the method, in which the information signal is subdivided into volumes, and a volume comprises a plurality of groups, characterized in that the volume has a volume application code that relates to all the groups of that volume in particular. This incorporation is advantageous in that the array can derive from the volume application code, the information structure for a period of time and does not need to analyze the application code of each group. Another embodiment for the method is characterized in that the volume application code is equal to the group application code of each of the groups in that particular volume and has a predetermined value if the groups in the volume have different application codes. of groups. This incorporation is advantageous because the array can derive from the volume application code if the group application code will vary in the groups considered. According to a second aspect of the invention, an information carrier of the type defined in the introduction paragraph is characterized in that the application data is included in the blocks and in that each block contains an application code indicating the structure of the in-formation, while the structure of the application data depends on the application code. This embodiment of the invention is advantageous, for example, in that for each block, the information structure and the application data with its structure are immediately known when an apparatus starts reading the information carrier at an arbitrary point, as after a fast forward operation of the information carrier of the tape type. According to a third aspect of the invention, an arrangement comprising mechanisms for receiving the information signal defined in the introductory paragraphs, mechanisms for processing the information and mechanisms for processing the application data, is characterized in that the arrangement comprises mechanisms to retrieve the application data of each block, mechanisms for detecting the application code, mechanisms for adapting the information processing mechanisms in dependence on the detected application code, and mechanisms for adapting the application data processing mechanisms in -pendence with the detected application code. This embodiment is advantageous in that information with different information structures can be received and processed without the need to transfer control information to the array via a separate channel or by the user. Another incorporation of the information reception arrangement is characterized in that the arrangement comprises adaptation mechanisms to adapt the information processing mechanisms depending on the application data. Another embodiment of the information reception arrangement is characterized in that the arrangement comprises detection mechanisms for detecting the group application code and adaptation mechanisms for adapting the application code detection mechanisms., so that the application code is replaced by the group application code, unless a group application code has a default value. This embodiment is advantageous, for example, in that if the arrangement is unsuitable for changing the information structure after each block, the application code detection mechanisms are allowed to operate at a lower speed. Another embodiment of the arrangement for receiving information is characterized in that the arrangement comprises detection mechanisms for detecting the volume application code and adaptation mechanisms for adapting the group application code detection mechanisms, so that the application code of group is replaced by the volume application code, unless the volume application code has a default value. This incorporation is advantageous, for example, in that if the arrangement is unsuitable for processing the specific information structures, a volume having said information structure can be rejected immediately. Another embodiment for the information reception arrangement is characterized in that the arrangement comprises reading mechanisms for reading the information signal from an information carrier in which the information signal is recorded. According to a fourth aspect of the invention, an arrangement for transmitting the information signal defined in the introduction paragraph is characterized in that the arrangement comprises mechanisms for generating the application code and mechanisms for determining the structure of the application data, both operations are carried out depending on the structure of the information of the information. Another incorporation for the information transmission arrangement in which the information structure has one or more substructures is characterized in that the arrangement includes mechanisms to generate the application data depending on the substructure of the information.

Another embodiment of the arrangement for transmission of information is characterized in that the arrangement comprises mechanisms for generating the group application code; code-code that relates to all the blocks of a particular group, the group application code is equal to the application code of each of the blocks in that particular group and has a default value if the blocks the group has different application codes. Another incorporation of the information transmission arrangement is characterized in that the arrangement comprises mechanisms for generating a volume application code, -code that relates to all the groups of a particular volume, the volume application code is equal to the code of group application of each of the groups in that particular volume and that have a predetermined value if the groups in the volume have application codes of different groups. Another embodiment of the information transmission arrangement is characterized in that the arrangement comprises mechanisms for registering the information signal in said information carrier. The invention will now be explained with reference to Figs. 1 to 12 in which: Fig. 1 shows an information signal subdivided into blocks; Fig. 2 shows an information transfer system; Fig. 3 shows an information carrier, - Fig. 4 shows a layered structure for application codes; Fig. 5 shows a subdivision of a block with a head; Fig. 6 shows a head of a block that contains an application code and application data, - Fig. 7 shows a Table of Contents for an information carrier; Fig. 8 shows a Disc Identification Table with volume application code; Fig. 9 shows a track identification table with track application code, - Fig. 10 shows an arrangement for receiving information with an information carrier; Fig. 11 shows an arrangement for transmitting information by means of a radio signal, - and Fig. 12 shows an arrangement for transmitting information by means of a master information carrier.

Fig. 1 shows diagrammatically an information signal subdivided into blocks 2. The information is contained in a flow 1 of symbol information which is represented in the usual way by a physical information signal, for example, by electrical signal values or optics A plurality of symbols collectively represents a significant amount of information and is called block 2. Special sync patterns (sync) 11 which indicate the heads of the blocks are also present in the information stream 1. A quantity of information, the so-called head 12, also identifies a block, is adjusted to each block. Fig. 5 provides a more detailed representation of said block with head. Symbols in a block represent information of a specific type such as audio, video or computer software, or combinations of various types. The way in which the symbols represent these different types of information is different, but, without needing to observe this way, it must always be known under the information retrieval from the information signal. This way of representation is called information structure. Examples of such information structures are CD-DA (CD Audio Digital) or the CDI which is described under the title "Compact Interactive Disc, a semblance of the designer", published by Kluwer (ISBN 9020121219). In addition to the information represented in this way, many applications need to support information related to the information, in addition here reference is made to the application data. With audio information, for example, there is a need to indicate the playback time or song texts. For other applications there is a need to indicate substructures of the information structure by means of application data, such as, for example, for said CDI. Within the information structure of the CDI, there are some application data available, which denote what type of information is concerned, such as video, audio, etc. These application data also contain an indication for the coding method for storing the signal, for example, the frequency limit for audio and the resolution and the Color Tables for video. Generally, the structure of the application data depends on the information structure and is thus always different. In this case, the destination must know the structure of the application data. In the method according to the invention, these application data 7 are included in the blocks and each block receives an application code 4, which is indicative of the information structure, while the structure of the application data depends on the code of application. These additions are preferably included in the head 12 of the block. Fig. 2 shows a system for executing a transfer of information according to the invention. The system comprises an array 21 for transmitting information, a channel 22 for transfer of information signal and an array 23 for receiving the information. The transmission arrangement will gather the information flow of information supplied from one or more sources and / or generate information in itself. Then, the transmission array 21 encodes the information stream 1 in a form appropriate for the transmitter channel 22. The transmission channel 22 may be of the customary type, such as a telephone-modem link, a data network or a satellite link.

The transmitter channel 22 may also use an information carrier in which the information signal is recorded, such as a tape or a disk in which the information signal is represented in magnetic or optical reading patterns. The reception arrangement 23 detects the flow 1 of information from the information signal and processes the information according to its particular information structure, this is known in the reception arrangement with the base of the application code. These application data are converted, as required, according to the structure as defined by the application code. The method is obviously not restricted to said examples of signal transfer. It is preeminently appropriate for a system for transferring digitally encoded information, in which there is no possibility of communication between the source and the destination prior to the current transfer of information, for example, the distribution of information on a CD or the transmission of information by means of radio waves or through a LAN to an unknown number of receivers of different types. The default information structure used in such communication is called in telecommunications, protocol. If a protocol is impossible, the destination must know the structure of the information. Due to the high density of information and therefore of small redundancy, it is not possible to easily derive the information structure, which must always be implicitly available, from the information signal. If the system is capable of transferring information from one or more information structures, it is in this highly attractive way to discover the structure of information and related information, for example, the method of error correction or the title of the information to be transferred, in the information signal itself. With the application code and the application data it is possible for the information structure for each block to be derived from an information signal itself. Fig. 3 shows by way of example a signal carrier in the form of a disk 30 in which the information signal is recorded in a spiral, physical pattern. The disk is logically subdivided into tracks 31 which contain one or a plurality of blocks. These tracks form, in this case, the groups in the information flow, while the disk forms a volume. An information carrier may also comprise a plurality of volumes; as a signal carrier which is referenced in a mui-session bearer. A Table of Contents is recorded on the disk in an area 32 with the intention of this purpose. The Table of Contents contains information about the carrier and the tracks, - an example of such Table is shown in Fig. 7. From the Table of Contents it is known which blocks together form a track. The reception arrangement immediately knows the information structures of all the blocks in this Table, so that this structure does not need to be determined again for each block. This reduces the necessary speed of the mechanisms to detect and adapt the information structure. A predetermined code, for example, $ FF (hexadecimal numbering system) then, denotes that the blocks in the tracks have different application codes and that the information structure must be determined block by block. The information carrier may contain, for example, information in a first format for a computer system of a first type and information of a second format for a computer system of a second type. By subdividing the information carrier into two tracks, a reading device that receives an instruction from a computer system of the first or second type, can simply supply the computer system with only the information of that particular information structure, without each computer has an installation to distinguish intentional information for the system from other information. Another improvement is achieved in that the information carrier contains a volume application code. Here too, a predetermined value, for example, $ FF, denotes that not all track application codes are the same. As a result, a reading device can simply determine if all the information in this information carrier can be processed or if a subsequent analysis by track is needed. Fig. 4 shows a layered structure for application codes. Each block in information flow 1 has an application code 4. The blocks are subdivided into groups, indicated diagrammatically by the connection lines 41. For each group, a group application code 5 is attached which is related to all the blocks in the group. The groups together form a volume, as diagrammatically shown by the lines 42. A volume application code 6 is added to the volume. Furthermore, the manner in which the information structure is determined is as described with respect to the information carrier in Fig. 3, in which, according to a hierarchical scheme, the volume application code is first detected and then the group application code, as required, and the application code for each block-which is detected if still necessary. Figs. 5 to 9 are shown in the Tables in which the position and length of the items in the Table are set in bytes. They only work as examples. Fig. 5 shows the structure of a block. At the beginning of the block synchronization the symbols 51 indicating the start of the block are placed. They are followed by the head 12 and then the field 52 for information for a particular information structure. Finally, some symbols 53 are added, which make it possible to detect errors that have resulted somewhere in the block during the transfer. Fig. 6 shows a head of a block with application code 4 and application data 7. As is customary, such a head contains an address 62 which only identifies the block. In addition, this head contains a track number 63, so that it is possible to detect the track number even without consulting the Table of Contents. Alternatively, it is possible for block number 63 to include blocks with different track numbers within a limit order in information stream 1. Since it is very important for the information processing of the block that the information in the head is correct, a revision code 64 of the usual type CRC Cyclical Redundancy Review is added. With this code it is possible in a simple and very reliable way to check if the information in the head contains errors. Fig. 7 shows an embodiment for a Table of Contents for disk 30. This Table of Contents contains a system identification 71 and is further sub-divided into fields for different types of information concerning the information bearer. The field 72 contains a Disc Identification Table and is shown in detail in Fig. 8. In addition, the fields 73 are reserved for a Track Identification Table of each track, the contents of which are shown in Fig. 9. The The disk identification table shown in Fig. 8 may include, for example, data such as the number of tracks on the disk. The Disk Identification Table is also an eminent location for volume application code 6. Fig. 9 shows a Track Identification Table. This Track Identification Table is repeated for each track in the Disc's Table of Contents. This Track Identification Table may contain, for example, data such as the address of the first and last block in the track. A track forms in this case a group. The Track Identification Table is thus also appropriate as a location for the group application code 5. Fig. 10 shows an arrangement for receiving the information stored on the disk 30. The disk 30 is read by a ray 80 of radiation focused to the disk by a radiation unit 81. The reflected radiation is influenced by the effects on the disk that represents the signal of in-formation. The radiation unit 81 derives the information signal from this reflected radiation. A system controller of the usual type (not shown) controls the speed of rotation of the disk and the placement of the radiation unit 81 on the track 31. The synchronization unit 82 (Sync) converts the information flow 1 from the information signal and isolates the blocks in this information flow in response to sync patterns 11. From sync 82 unit, the blocks are transferred to the processing unit 83 and to the detection unit 84. From the processing unit, the information goes to one or more destinations through the outputs 85. These destinations can be, for example, an audio system or an image screen. These application codes are detected in the detection unit 84 and are used to set the processing unit to process the information according to a particular information structure. If the information structure is, for example, the CDI structure, the first processing unit 83 should derive the application data from each block, because this application data denotes which substructure has the information in the block, such as for example , an audio signal encoded according to a specific compression algorithm. In addition, the detection unit 84 may also comprise mechanisms for detecting the track application code and the volume application code. The detection unit may use the track application code and the volume application code to provide a single setting of the proving unit for a longer period of time, and has also been described with reference to Fig. 3 The detection unit can also pass in the track application code and the volume application code to the system controller and this system controller can then skip this particular track or refuse the complete information bearer if the array is incapable of processing the particular information structure, or if the user has instructed the system controller to read a specific type of information from the information bearer. There can also be several processing units (not shown) in which the blocks are transferred to the correct processing unit in response to these application codes. Fig. 11 shows an arrangement for transmitting information. Information from one or more sources 91, such as a microphone, or computer graphics data, is coded into the desired information structure and subdivided into blocks by a processing unit 92. A generator 93 determines the application code, the group application code and the volume application code in response to the information structure. The system controller (not shown) is instructed by the user to make a subdivision of information into groups and volumes, and this subdivision is passed to the generator 93. The information flow is converted into an information signal by the unit 94 sync and provides the sync patterns 11. The transmission unit 95 amplifies the information signal, for example, it modulates the same in an information carrier, and by means of an antenna 96, transmits the information signal to one or more receivers. The arrangement shown can be, for example, a radio transmitting station in which the traffic information having a second information structure is co-transmitted with the musical signal which has a first information structure. A group can then be used to describe a district and a volume to describe a country. A third information structure could, for example, be the co-transmission of the texts of the songs, so that they can be shown on a receiver. A group can be a clue and a vo-lumen can then be a program. For such an arrangement it is also desirable to include a group number in the head of each clock, because in this case, blocks having different information structures can be transmitted alternately. For example, the audio information must be converted into an uninterrupted flow at its destination, and in this way, of a nature so defined in real time. If the other blocks cause long interruptions in the flow of audio information, this will require large memories in the reception array and the result would be an additional delay between transmission and reception. Fig. 12 shows an arrangement for transmitting information, in which the information is distributed in carriers of information. First, a master information bearer is made with the arrangement shown. From this master information carrier, a multiplicity of information bearers are made by means of a customary process which molds and presses (not shown). In this arrangement, the processing unit 92 encodes the information of one or more sources 91, such as a video camera, or a computer program and the application data such as subtitling into a desired information structure and subdivides the information. in blocks. The distribution of the information on the tracks is determined, for example, by an editor and passed to a generator 93. The generator 93 determines the application code, the track application code and the volume application code as a function of the information structure, and stores the structure of the application data in the sync unit 94. The information flow is converted into an information signal by means of the sync unit 94, and is provided with the sync patterns 11. The channel coding unit 100 encodes the information signal in a manner appropriate for the disk-like information carrier and transfers the information signal with the radiation unit 101. The unit 101 introduces effects on the master information bearer 103 by a radiation beam 102. A system controller of the customary type (not shown) provides control of the disk rotation speed and placement of the unit 101 on the track 31. The incorporations for the arrangements are not restrictive to the examples of Figs. 10, 11 and 12 and may comprise any arrangement for receiving and / or transmitting information, in which an application code and application data, as required, are included in the information flow in the manner described in the method.
