Abstract

The invention relates to a combined broadcast and web radio in a portable device. The device is arranged to switch automatically between broadcast radio and web accessed radio in dependence of received signal strength and quality. The device comprises: a radio receiver tunable to broadcast radio frequencies; a web radio interface adapted to access radio stations through a global communications network; a control unit capable of controlling the radio receiver and the web radio interface and adapted to monitor received signal strength on the radio receiver. The control unit is adapted to switch the device from a broadcast radio reception mode to a web radio reception mode, if the monitored received signal strength of the broadcast radio drops below a first limit.

Claims

1. A portable device comprising:

a radio receiver tunable to broadcast radio frequencies;

a web radio interface adapted to access radio stations through a global communications network;

a control unit capable of controlling the radio receiver and the web radio interface and adapted to monitor received signal strength on the radio receiver;

wherein the control unit is adapted to switch the device from a broadcast radio reception mode to a web radio reception mode, if the monitored received signal strength of the broadcast radio drops below a first limit.

2. A portable device according to claim 1, wherein, if the monitored received signal strength drops below said first limit, the control unit is adapted to perform a search for a better broadcast radio channel frequency than an original frequency with a program matching the broadcast radio original frequency, before switching the device from a broadcast radio reception mode to a web radio reception mode.

3. A portable device according to claim 2, further comprising storage means for receiving and storing a list of alternative frequencies;

wherein the control unit is adapted to perform next search using the list of alternative frequencies.

4. A portable device according to claim 3, wherein the control unit is adapted to use a url address for web access in the web radio reception mode, the url being included in the list of alternative frequencies.

5. A portable device according to claim 3, wherein the control unit is adapted to use a url address for web access in the web radio reception mode, the url being included as part of the Radio Text (RT) defined within the RDS standard.

6. A portable device according to claim 1, the control unit is adapted to switch the device from a web radio reception mode to a broadcast radio reception mode, if the monitored received signal strength of the broadcast radio rises above a second limit.

7. A portable device according to claim 1, wherein the control unit is adapted to monitor received signal strength of the global communications network to which the the web radio interface is tuned;

and to switch the device from a web radio reception mode to a broadcast radio reception mode, if the monitored received signal strength of the global communications network drops below a third limit.

8. A portable device according to claim 1, wherein the device is a portable computer, a mobile telephone, a pager, a communicator, a smart phone, or an electronic organiser.
