  Solutions for Identifying Media Tracks, Memorizing their Identification Information, Applying Services to this Information

1. Problem Statement

When consuming a media track on a conventional analogue receiver (e.g. listening to a song on a car radio), it is usually difficult to identify this track (with information such as title, interpreter, etc.) to be able to use this information for further actions
(e.g. for buying). One possible way would be to write down the available track information. Of course, this is only feasible if the track ever gets announced or a radio data system displays some information. With the advent of internet play lists a person could also note the time and station to search for the track identifier later at the sender's Internet pages. Both ways are cumbersome and sometimes impractical, for example when driving a car.

    In a couple of years, if digital receivers are becoming more prevailing, this problem could go away through the extensible capabilities of digital receivers with additional application and data functionalities. However, our solutions focus on the conventional, analogue receivers which are not expected to be replaced instantly by digital ones once they are available, since the conventional install base is huge and likely to stay in operation for a number of years. Nevertheless, our solution can also be deployed to any digital receiver.

2. Problem statement

Our solution implements parts or all of the following scenario:
A. Identification of a media track played on a receiver device
B. Transfer and storage of captured identifiers to a service providing instance
C. Mapping of captured identifiers to different representations
D. Application of services to stored identifiers

3. Solutions
A. Identification
The identification can either be done a) by the receiver itself or b) through a device which is separate from the receiver.

    In case a) the receiver will be functionally extended. There is an interface to initiate the capture of a media track identifier, e.g. an input device such as a button. Activating the input device lets the receiver capture the available identification of the currently played media track. This is either data from a data channel (such as RDS in Europe) or the data which is available through the current tuning of the receiver to a specific station (such as frequency, time, date).

    Case b) leaves the receiver unchanged and uses a separate capturing device. Again, this device will either be able to use a data channel providing identification information or it will rely on tuning information. If there is data channel information available, the device needs to know the current station and it requires a user signal at the time the to be captured media track is played. The device can be either local...
