System and method for reducing the service switching time between frequencies in a digital radio

A method for enhancing user experience in a digital radio by reducing the service switching time between frequencies, the method comprising:

• a. uploading a first service channel information and a second service channel information of a plurality of frequencies of a plurality of digital radio stations to a central server;
• b. storing the first service channel and second service channel information of the plurality of digital radio stations in the central server;
• c. fetching or downloading service channel information updates by each radio station of the plurality of digital radio stations from the central server;
• d. sending information channel data as part of a separate data service within the data channel of each frequency from the radio station to a digital radio receiver;
• e. receiving and storing the information channel data of the plurality of frequencies by the receiver;
• and
• f. using the stored channel data information for demodulating and decoding when the user tries to switch to another frequency by the receiver.

A system for enhancing user experience in a digital radio by reducing the service switching time between frequencies, the system comprising:

• a digital radio transmitter to transmit digital data in a digital radio broadcast standard, wherein the digital radio broadcast standard is Digital Radio Mondiale (DRM), the digital radio transmitter comprises:
• a first service channel to carry basic service selection information;
• a second service channel to carry information required for decoding;
• and
• a main service channel to transmit digital audio services and data services including first and second channel information of a plurality of frequencies;
• a central server to store information channel data of a plurality of digital radio stations;
• and
• a digital radio receiver to store the first service channel and the second service channel information of frequencies other than the currently tuned frequency to a receiver internal storage, wherein the receiver is configured to use the stored channel data information for demodulating and decoding when the receiver switches to another frequency,
• wherein the radio station is configured to download the information of the first service channel and the second service channel based on a notification from the central server.
