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 an audiovisual program in a reading device, comprising:

reading the audiovisual program;

interrupting the reading of the audiovisual program when at a first point in the audiovisual program a user actuates a command for reading the audiovisual program starting at a second point thereof;

marking the first point of the audiovisual program;

reading the audiovisual program starting at the second point in the audiovisual program;

interrupting the reading of the audiovisual program when at a third point in the audiovisual program, the user actuates a further command;

comparing a time interval between the third and second points to a predetermined time; and

marking the third point of the audiovisual program if the time interval between the third and second points is greater than the predetermined time, and not marking the third point of the audiovisual program if the time interval between the third and second points is not greater than the predetermined time.

2. The method of claim 1, wherein the user actuates commands using at least one user control device having at least one control key.

3. The method of claim 1, wherein a previous marking is not erased by a subsequent marking.

4. The method of claim 1, wherein each point of the audiovisual program is associated with an address, the method comprising registering the address associated with each marked point in a memory.

13. The method of claim 1, wherein the further command is for reading the audiovisual program starting at a fourth point thereof, the method comprising moving to the fourth point of the audiovisual program.

14. The method of claim 13, wherein the first and fourth points are the same.

5. The method of 4, comprising:

reading an address registered in the memory; and

moving to the point of the audiovisual program associated with the address read.

6. The method of claim 5, wherein each marked point is associated with a numbered key of a user control device, and wherein the address read is the address registered in the memory for the marked point associated with the actuated numbered key.

7. The method of comprising providing a graphical display with a representation of a duration of the audiovisual program and a tag indicating a location in the audiovisual program of each marked point.

8. The method of claim 7, wherein with each tag is associated with a marking number.

9. The method of claim 7, wherein a timeout step is triggered on completion of a predetermined time after each marking step making it possible to interrupt the graphical display step.

10. The method of claim 9, wherein the timeout step triggers the display of an indicator indicating that at least one marking is recorded.

11. The method of claim 10, wherein the indicator being displayed, a first actuation of a user control device triggers the graphical display step and a second actuation triggers the moving step.

12. The method of comprising displaying a graphical information item indicating that at least one point has been marked.

15. A system for reading an audiovisual program comprising:

means for reading the audiovisual program;

a user input device for interrupting the reading of the audiovisual program so as to move the reading of the audiovisual program to another point thereof;

a marking circuit, the marking circuit;

marking a first point of the audiovisual program upon actuation of the user input device to move to a second point of the audiovisual program,

upon further actuation of the user input device at a third point in the audiovisual program, comparing a time interval between the third and second points to a predetermined time, and

marking the third point of the audiovisual program if the time interval between the third and second points is greater than the predetermined time, and not marking the third point of the audiovisual program if the time interval between the third and second points is not greater than the predetermined time; and

moving means for moving the reading of the audiovisual program.

16. The system of claim 15, wherein each point of the audiovisual program is associated with an address, the marking circuit registering the address associated with each marked point in a memory.

17. The system of claim 16, comprising a reading circuit for reading an address registered in the memory, wherein the moving means moves the reading of the audiovisual program to the point associated with the address read.

18. The system of claim 17, wherein each marked point is associated with a numbered key of the user input device, and wherein actuation of a numbered key causes the reading circuit to read the address registered in the memory for the marked point associated with the actuated numbered key.

19. The system of claim 18, wherein the marking circuit assigns a marking number to each address registered in the memory, the marking numbers corresponding to the numbered keys of the user input device.
