Abstract

An apparatus for reproducing an information signal stored on a first storage medium (4). The apparatus comprises a reading unit (2) for reading the information signal from the first storage medium, an output unit (6) for supplying the information signal to a display unit, an user controllable input unit (8) for receiving commands to enable an user to access the information signal. The user controllable input unit is adapted to receive a first command at an instant. The apparatus further comprises a unit (10) for controlling the reading unit to start reading the information signal from said storage medium at a second position in the information signal in response to said first command, the information signal at said second position having features showing a similarity with features of the information signal at a first position read at said instant of receiving said first command, or a features of an information signal read prior to said instant.

Claims

1. An apparatus for reproducing an information signal stored on a first storage medium, the apparatus comprises:

reading means for reading the information signal from the first storage medium,

output means for supplying the information signal to a display unit,

user controllable input means for receiving commands to enable a user to access the information signal, wherein the user controllable input means is adapted to receive a first command at an instant, the apparatus further comprises

means for controlling the reading means to start reading the information signal from said storage medium at a second position in the information signal, the information signal at said second position having features showing a similarity with features of the information signal at a first position read at said instant of receiving said first command, or features of the information signal read prior to said instant and further adapted to read a data signal from a second storage medium, the data signal comprising information about positions in the information signal and other positions in the information signal having similar features.

2. The apparatus according to claim 1 wherein the apparatus further comprises:

extraction means for extracting said features from the information signal,

means for determining dependence of said extracted features positions having similar features so as to obtain said data signal, and writing means for writing said data signal on said second storage medium.

3. The apparatus according to claim 1 wherein the features have a relationship with the color histogram of images corresponding to positions in the information signal.

4. The apparatus according to claim 1 wherein the features have a relationship with the color grid histogram of images corresponding to positions in the information signal.

5. The apparatus according to claim 1 wherein the features have a relationship with the color structure histogram of images corresponding to positions in the information signal.

6. The apparatus according to claim 1 wherein the user controllable input means comprises input means for controlling the reading means to start reading the information signal at a position which follows the position in the information signal at said instant.

7. The apparatus according to claim 1 wherein the user controllable input means comprises input means for controlling the reading means to start reading the information signal at a position which is preceding to the position in the information signal at said instant.

8. Method of reproducing an information signal stored on a first storage medium, the method comprises the step of:

reading the information signal from the first storage medium,

supplying the information signal to a display unit,

receiving commands to enable a user to access the information signal, characterized in that the method further comprises the steps of;

receiving a first command at an instant,

start reading the information signal from said storage medium at a second position in the information signal, the information signal at said second position showing a similarity with the information signal at a first position read at said instant of receiving said first command, or showing similarity with a part of the information signal read prior to said instant and

reading a data signal from a second storage medium, the data signal comprising information about positions in the information signal and other positions in the information signal having similar features.

9. A computer readable-medium having stored thereon a program for enabling a processor to carry out the method according to claim 8.
