Abstract

This invention relates on a method and a system for reading a set of recorded information that is applicable to a reading system making it possible to read sequential information. In a first step, the user marks a first information sequence currently being read triggered by a first interrupt by actuating a device for triggering a special processing mode. This special mode can be trigger by a fast movement key, this mode allows reading a second information sequence. In a second step, the user can rewind to the first information sequence interrupted and marked during the previous marking step. This rewind step is triggered during the reproduction of the second sequence when the user actuates a rewind device. The invention is applicable to the reproduction by a user of recorded information and more particularly to the displaying of an audiovisual work.

Claims

1. A method of reading a set of recorded information that is applicable to a reading system making it possible to read information, especially sequential information, and comprising at least one device for triggering a mode of special processing of the information to be read, wherein it comprises:

a. marking a first information sequence currently being read triggered by a first interrupt when the user actuates said device for triggering a mode of special processing with a view to reading a second information sequence;

b. rewinding to the first information sequence interrupted and marked during the previous marking step, this rewind step being triggered by the user during the reproduction of the second sequence when the user actuates a rewind device.

14. The method of reading information as claimed in claim 927, wherein, the simplified indicator being displayed, a first actuation of the rewind device triggers the graphical display step and a second actuation triggers the rewind step.

20. The method of reading information as claimed in claim 1, wherein it is applicable to a system comprising several control devices or control keys and in that the rewind step can be controlled by any one of these control devices.

21. The method of reading information as claimed in claim 1, wherein, after a first marking step, if the user again actuates said device for triggering a mode of special processing after a time of reading of the second sequence that is greater than a determined time, a second marking step is triggered and so on and so forth.

22. The method of reading information as claimed in claim 21, wherein a previous marking is not erased by a subsequent marking.

23. The method of reading information as claimed in claim 1, wherein, after a first marking step, if the user again actuates said device for triggering a mode of special processing after a time of reading of the second sequence that is less than a determined time, a second marking step is not triggered.

24. The method of reading information as claimed in claim 21, wherein to each information item is assigned an address or indication for pinpointing this information item and in that each marking step provides for the registering, in a temporary memory, of the address or of the pinpointing indication corresponding to a sequence of information.

25. The method of reading information as claimed in claim 23, wherein the rewind step comprises a phase of reading said memory and a phase of addressing the information sequence corresponding to a pinpointing indication read from the temporary memory.

26. The method of reading information as claimed in claim 23, wherein various pinpointing indications corresponding to various markings are numbered in the temporary memory and in that the rewind device comprises numbered keys, the actuation of a numbered key allowing the reading of the pinpointing indication bearing the same number, and the rewind step providing for the rewind to the sequence situated at the pinpointing indication read.

27. The method of reading information as claimed in claim 1, wherein it provides for a step of graphical display comprising a representation of the duration or of the length of the set of information recorded as well as the displaying on this graphic of a tag pinpointing the location of each sequence marked.

28. The method of reading information as claimed in claim 27, wherein with each tag is associated a marking number.

29. The method of reading information as claimed in claim 1, wherein there is provided a step of displaying a graphical information item indicating that at least one marking step has been triggered.

30. The method of reading information as claimed in claim 27, wherein a timeout step is triggered on completion of a determined time after each marking step and making it possible to interrupt the display step.

31. The method of reading information as claimed in claim 30, wherein the timeout step triggers the display of a simplified indicator indicating that at least one marking is recorded.

2-13. -13. (canceled)

15. A system for reading a set of recorded information making it possible to read information in series and comprising at least one device for triggering a mode of special processing of the information to be read capable of interrupting the normal reading of the information so as to move to another sequence of the recording, wherein it comprises a circuit for marking an interrupted sequence receiving a special mode signal and instructing in exchange the marking of the address of the sequence interrupted in a memory.

16. The system for reading a set of information as claimed in claim 15, wherein it comprises at least one control device for instructing rewind to an interrupted sequence as well as a circuit for reading the memory instructing the reading of the interrupt address in said memory and instructing the rewind to the reading of the recording from this interrupt address.

17. The system for reading a set of information as claimed in claim 15, wherein the marking circuit instructs the registering in a memory of one or more interrupt addresses.

18. The system for reading a set of information as claimed in claim 15, wherein the marking circuit assigns a serial number to each interrupt address.

19. The system for reading a set of information as claimed in claim 18, wherein the rewind control device comprises numbered keys, the signal emitted by the actuation of a numbered key being used by the reading circuit to instruct the reading from the memory of the address having the same serial number as the number of the numbered key actuated.
