Abstract

The method according to the invention enables a user to navigate to a desired part (310) in a recording (302). The recording (302) is created from a received signal (110), whereby a plurality of positions in the recording are associated with respective points in time (316) from which the signal representing content at these positions has been received. The user specifies a desired point in time (320), from which the signal representing the desired part is known to have been received. Subsequently, playback of the recording is proceeded at the particular position (322) in the recording of which the associated point in time substantially equals the desired point in time, whereby verification whether the associated point in time substantially equals the desired point in time is executed by a device.

Claims

1. A method of enabling a user to navigate to a desired part in a recording, comprising:

creating the recording from a received signal,

associating a plurality of positions in the recording with respective points in time from which the signal representing content at these positions has been received,

obtaining a desired point in time, from which the signal representing the desired part is known to have been received, and

proceeding to the particular position in the recording of which the associated point in time substantially equals the desired point in time, whereby verification whether the associated point in time substantially equals the desired point in time is executed by a device.

2. A method as claimed in claim 1, whereby associating the plurality of positions in the recording with respective points in time is realized by:

assigning to the recording a begin timestamp indicating the point in time from which the signal representing the begin of the recording has been received, and

assigning to each of the plurality of positions in the recording a position timestamp indicating, relative to the begin timestamp, the point in time from which the signal representing content at that position has been received.

3. A method as claimed in claim 1, whereby associating the plurality of positions in the recording with respective points in time is realized by assigning to each of the plurality of positions in the recording a position timestamp indicating the point in time from which the signal representing content at that position has been received.

4. A method as claimed in claim 1, whereby the recording is created from a received broadcast signal and whereby the desired point in time is the scheduled broadcast time of the broadcast signal representing the desired part.

5. A method as claimed in claim 4, whereby an offset is obtained indicating the difference between the scheduled broadcast time and the actual point in time from which the broadcast signal representing the desired part has been received and whereby the verification whether the associated point in time substantially equals the desired point in time is based on the offset.

6. A method as claimed in claim 5, whereby the offset is obtained from an Electronic Program Guide.

7. A reproduction device enabling a user to navigate to a desired part in a recording, wherein a plurality of positions in the recording are associated with respective points in time from which the signal representing content at these positions has been received, the device comprising:

verification means for verifying whether the associated point in time of a particular one of the plurality of positions in the recording substantially equals a desired point in time from which the signal representing the desired part is known to have been received, and

proceeding means for proceeding to the particular one of the plurality of positions in the recording of which the associated point in time substantially equals the desired point in time.

8. A reproduction device as claimed in claim 7, further comprising input means for obtaining the desired point in time.

9. A reproduction device as claimed in claim 7, wherein the recording is created from a received broadcast signal and wherein the desired point in time is the scheduled broadcast time of the broadcast signal representing the desired part, the device further comprising offset obtaining means for obtaining an offset indicating the difference between the scheduled broadcast time and the actual point in time from which the broadcast signal representing the desired part has been received, and wherein the verification means is arranged to verify whether the associated point in time substantially equals the desired point in time on basis of the offset.

10. A reproduction device as claimed in claim 7, wherein the offset obtaining means is arranged to obtain the offset from an Electronic Program Guide.

11. A computer program product comprising software code for causing a processor to:

enable a user to navigate to a desired part in a recording, wherein a plurality of positions in the recording are associated with a point in time from which a signal 110 representing content at that position has been received,

verify whether the associated point in time of a particular position in the recording substantially equals a desired point in time from which the signal representing the desired part is known to have been received, and

proceed to the particular position in the recording of which the associated point in time substantially equals the desired point in time.
