c) comparing the characteristic information of the user content items stored on the client device with characteristic information stored on the server and suitable to identify the server content items; and

d) updating the user profile on the server based on the comparison carried out in c) by generating automatic feedback in response to the characteristic information of the user content items stored on the client device matching characteristic information stored on the server and generating user feedback information based on a user input related to the respective server content item,

wherein

the user profile comprises a plurality of channels,

one of the user content items is assignable to at least one of the plurality of channels, and

the user profile is updated, based on the respective user content item, merely with respect to a respective one of the plurality of channels to which the respective user content item is assignable,

wherein steps b-d are repeated each time a user content item is added to and/or deleted from the client,

wherein the user input includes explicit and implicit input, and

wherein the implicit input is based in part on skipping of a transfer process of a server content item.

2. The method according to claim 1, wherein the implicit input is further based on a scroll speed of a visually displayed content item.

15. The method according to claim 3, wherein a user input is requested on the client prior to carrying out the steps as defined in any one of the preceding claims and the updating the user profile is either continued, retarded or cancelled depending on the user input.

3. A method for updating a user profile on a server based on user content items on a client, the server being able to communicate with the client via a communication network, comprising:

a) transferring characteristic information from the server to the client, the characteristic information being suitable to identify each of a part of server content items;

b) for each of the part of server content items;

b1) comparing, at the client, the respective characteristic information received from the server with characteristic information stored on the client suitable to identify each of the client'"'"'s content items, and

b2) in response to the characteristic information of a respective server content item matching with the characteristic information of a user content item stored on the client device, generating, at the client, automatic feedback information, or

b3) in response to the characteristic information of a respective server content item not matching with the characteristic information of a user content item stored on the client device, generating, at the client, user feedback information based on a user input related to the respective server content item or based on the absence of an user input, wherein the automatic feedback information and the user feedback information correspond to one out of possible stages or states of user feedback information;

c) transferring, from the client to the server, the feedback information for each of the part of the server content items; and

d) updating the user profile at the server based on the automatic user feedback information and/or user feedback information of each of the part of server content items, wherein the part of server content items comprises server content items of a content recommendation list stored on the server,

wherein step b is repeated each time a user content item is added to and/or deleted from the client,

wherein the user input includes explicit and implicit input, and

wherein the implicit input is based in part on skipping of a transfer process of a server content item.

4. The method according to claim 3, wherein a number of possible stages or states of user feedback information equals two.

5. The method according to claim 3, wherein the characteristic information of a content item corresponds to the content item itself and/or to an identification code identifying the content item.

6. The method according to claim 3, wherein the updating the user profile at the server further comprises:

for each of the user content items showing a match with a respective server content item, determining if there is descriptive data available for the respective server content item on the server.

7. The method according to claim 6, further comprising, in case descriptive data are available for the respective server content item, updating the user profile based on the descriptive data available for the respective server content item.

8. The method according to claim 6, further comprising, in case no descriptive data are available for the respective server content item, discarding the respective server content item when updating the user profile.

9. The method according to claim 3, further comprising, in case no descriptive data are available for the respective server content item, analyzing the respective server content item and updating the user profile based on a result of the analysis.

10. The method according to claim 3, wherein, in case the user profile comprises a plurality of channels, whereas content items are assignable to at least one channel, updating the user profile based on the respective server content item merely with respect to the at least one channel.

11. The method according to claim 10, further comprising:

rating the respective server content item with respect to each of the channels; and

determining at least one channel as a channel having a best rating.

12. The method according to claim 11, wherein the channel having the best rating is updated as a best channel.

13. The method according to claim 10, wherein each channel relates to a type of content item.

14. The method according to claim 3, wherein the respective server content item is discarded from updating the user profile in case a best rating does not exceed a predetermined minimum rating.

16. A non-transitory computer-readable storage medium having embedded therein instructions, which when executed by a processor, cause the processor to perform a method according to claim 3.

17. The method according to claim 3, wherein the automatic feedback information cannot be distinguished from manually entered user input.

18. A client being configured to communicate with a server via a communication network for updating a user profile on the server based on user content items on the client, comprising:

circuitry configured to

receive characteristic information from the server, the characteristic information being suitable to identify each of a part of server content items;
