Abstract

A portable media player (2) with an identity, an adaptable information item containing a media list of titles linked to the identity, two networks and an access key linked to the identity are all present in the system. The media list is adapted by providing access to the information item using a communication link with the access key via the second network (10), e.g. Internet. The media player communicates with the first network (8), e.g. mobile phone network, so that the player sends the identity associated with it. The identity received by the first network is used to request the media list from the information item. A media file is then sent to the player via the first network, after which at least one of the titles disappears from the media list.

f

Personal media system

The invention relates to a method and a device for a personal media system, wherein an identifiable media viewer can receive and display a media file from a personal preferred list.

Music is considered as the most popular form of entertainment and as a very effective form of relaxation.

Music and other media can be listened to and / or reproduced in many ways, such as with an MP3 player, a sound system, a portable video / TV set, a walkman or radio. If the listener wants to determine the content of the music himself, the listener needs a carrier on which the music is stored, such as a CD or an MP3 memory card.

15 The radio is still one of the most popular media. The difficulty with this is that you can only listen to the programs broadcast by the different radio stations.

The cellular networks for, for example, mobile telephones are also known. With a mobile telephone it is possible to make contact with the network at any location, the mobile telephone being identified, and to communicate via the network with other devices connected to this network. Data files can also be exchanged with mobile phones.

The communication is digital, 2-channel and takes place on the basis of protocols. The bandwidth with which mobile phones can communicate via the network is limited.

A problem with current systems is that listening to media, such as music, at any location means that the user must bring along a carrier on which his preferences are stored. The capacity of the I carrier is limited, and the content of certain carriers is not | 1 023919_ H easy to adjust to changing preferences. The object of the invention is to provide a system in which a user can listen to his preferences at any location, without carrying those preferences on a carrier. This object is achieved with a method according to claim 1.

According to the invention, the user has a media player with him. This can be connected to a first I network. The first network comprises, for example, the existing cellular networks for mobile telephones. The media viewer is provided with an identity, for example

I a unique name applied to a SIM card or other I

I smart card. The media viewer is provided with a power supply I

so that it can be released. The media player is I

I 15 connectable with a first network. The communication is in I

both directions. The media viewer identifies himself I

I by giving his identity to the network. When I

I the identity is known, the media viewer becomes access I

I given up to the first network. Based on the received I

I identity is coupled to the first network in an I

I looked up memory in a database, a media list that I

I is linked to the relevant identity. The media list I

I contains a number of titles. When the relevant media list I

is found, a title will be selected from the list, I

25 after which a media file that belongs to the title, via the I

first network is sent to the media viewer. The I

media viewer receives the media file and displays it, I

for example, by replacing the sound from the sound file I

to give. The communication takes place in a known manner, I

For example using an I known to the person skilled in the art

protocol. The various conversions, from electronic signal I

to audio signal, are also known to those skilled in the art and I

according to the state of the art in various ways I

f <.

3 take place. Use can be made of analog and / or digital signal processing, both in the networks and in the communication between the media player and the network.

The data file is adapted by means of a communication connection running over a second network. The relevant media list can be adjusted by means of an access key that is related to identity. Titles can be added. The title is related to or refers to a media file. The second network can be, for example, internet, to which the user has access via a PC by means of a modem and other techniques known to those skilled in the art.

According to the method of the invention, a personal media system is formed, wherein the preferred media can be received by the user by means of an identifiable receiver. The user has chosen these media himself by indicating preferences in a database accessible via a second network.

It is advantageous to store the media file in a memory connectable to both networks, preferably via a communication link over the second network, an address being assigned to the media file, and a reference to the address with the title in the media list. included. When a title with an identity is requested from the data file, reference will be made to the media file which can then be read from the memory and sent over the first network to be sent to the user. Different identities may have included the same titles in the relevant media lists 30, with reference to the same address. This saves storage capacity. This system is particularly advantageous when compiling the database of preferences 1023910

Preferably, the data file comprises time data associated with a title, in which a time has been recorded, and the media file of that title at that time is sent via the first network to the media player. This allows the user to specify a time schedule on which certain titles are broadcast. This can be a daily recurring schedule, which is for example adapted to the working hours.

Preferably, the media list is sent to the media viewer and displayed on the media viewer. This allows the user to see on the media viewer what his set preferences are at that time. Preferably a preference is indicated on the media viewer by the user, which is then sent to the first network, received by the first network and whereby a processing takes place which leads to the selected title and the associated media file being listened to on the media viewer, because the media file is sent via the first network. This allows the user to select the title from his favorite list that is currently displayed preferably.

The invention also relates to a system according to claim 8. A media file is received and displayed via a first network, which media file is linked to the preferences of the user included in a data file and indicated via a second network. The connection takes place because the media player and the relevant preferences are linked to the same identity.

Via the second network a data exchange takes place in which, after checking on an access key, which is linked to the identity, a user can adjust the media list for that identity in the data file, by recording or deleting titles. The titles refer to media files stored in memory that are accessed through 1023919

With the system according to the invention, media file is linked to the media list of a specific identity, only transmitted at times when the media player with that identity is switched on and is detected / identified by the first network. After identification, a music file is called up and sent via the processing means. When the connection is broken with the first network, for example due to switching off or loss of reception from the media player, the transmission is stopped.

The identity can preferably be stored on a sim card or other smart card that can be placed in the media display. Such systems are generally known to those skilled in the art.

20 Different techniques are available for communication between the media player and the first network.

Known techniques are frequency division multiplex or FDM, time-divided multiple access or TDMA, and an encryption that takes place near one time in time on one frequency of different calls, and code distribution multiple access or CDMA. With TDMA, the broadcast data is first digitized and then combined into a single digital stream on a single frequency channel. TDMA divides each channel into time sections. At 30 FDM, a single media viewer will use 10 Khz. With TDMA-based D amplifiers or digital amplifiers, three media playback broadcast data can be placed on that single frequency, thereby tripling the __1 02 39 1 9 ^ ____ Η

9 recognized media files in a signal playable on display means. This allows different types of media files to be displayed on the media viewer. The recognition means can distinguish a media file on structure, encryption and so on. Certain media files are only audio signals and the media processing means then only have to provide the speaker with an electronic signal. The recognition means and media processing means may comprise software that can be updated over time, by making new versions available on the first network, and being sent to the media processor. As a result, future format formats of media files can also be used on the "older" media viewer. This makes it possible to keep up to date with the technology, and so that the most efficient conversion technology / shipping technology can always be applied. This automatic updating function can also be used for the connecting means of the media reproducer, so that it can be adapted to new protocols, as long as no new hardware is required for this.
