Abstract

Claims (84)

1. A method comprising:

receiving via a broadcast channel, at a media device, a broadcast media stream transmitted by a broadcast system, and concurrently receiving via a communication channel, at the media device, a service transmission at a timing synchronized with a timeline of contents in the broadcast media stream, the service transmission comprising information about the contents of the broadcast media stream;

detecting at the media device when the information comprises data corresponding to given one or more search parameters; and

4. The method of claim 3 , wherein the search parameters further comprise information about at least one of the following:

name of a program;

name of a music track;

style of a music track;

artist performing in a music track; and

names of albums in which a music track is included.

5. The method of claim 1 , further comprising:

identifying a program or a music track transmitted in the broadcast media stream on the basis of the detection;

performing a frequency transformation on the broadcast media stream;

comparing the frequency transformation with at least one stored frequency transformation to further detect starting and ending times of the program or the music track;

determining to start recording the program or a music track transmitted in the broadcast media stream at a detected starting time;

determining to end the recording at a detected ending time; and

determining to store the recording in a memory of the media device.

6. The method of claim 1 , further comprising:

determining to indicate an ongoing recording process on a display of the media device, wherein the broadcast media stream is transmitted at timing determined independently from a user of the media device.

7. The method of claim 1 , further comprising:

determining to perform a spectral analysis on the received broadcast media stream;

comparing the spectral analysis with at least one stored spectral analysis; and

controlling the recording of the broadcast media stream on the basis of the comparison.

8. The method of claim 1 , further comprising:

determining to perform silence detection on the received broadcast stream; and

controlling the recording of the broadcast media stream on the basis of the detection.

9. A device comprising:

a receiver configured to receive via a broadcast channel a broadcast media stream transmitted by a broadcast system, and concurrently receiving via a communication channel a service transmission at a timing synchronized with a timeline of contents in the broadcast media stream, the service transmission comprising information about the contents of the broadcast media stream;

a memory for storing data; and

a processor connected to the receiver, transceiver and the memory, and configured to detect when the information comprises data corresponding to given one or more search parameters and to determine, independently from a user of the media device, to record the broadcast media stream in the memory on the basis of the detection.

10. The device of claim 9 , further comprising:

a user interface configured to receive the search parameters from a user of the device,

wherein the processor is further configured to determine to store the search parameters in the memory of the device, and the service transmission is received at the media device over a radio interface of a cellular telecommunication system.

11. The device of claim 9 , wherein the processor is further configured to:

detect when a service transmission comprises data corresponding to the search parameters;

identify a program or a music track transmitted in the broadcast media stream on the basis of the detection;

determine to perform a frequency transformation on broadcast media stream;

compare the frequency transformation to at least one stored frequency transformation to detect starting and ending times of the program or the music track;

determine to start recording the program or music track transmitted in the broadcast media stream at a detected starting time;

determine to end recording at a detected ending time; and

determine to store the recording in the memory of the device.

12. The device of claim 9 , wherein the processor is further configured to:

determine to perform spectral analysis on the received broadcast stream;

compare the spectral analysis with at least one stored spectral analysis; and

control the recording of the broadcast media stream on the basis of the comparison.

13. The device of claim 9 , wherein the processor is further configured to:

determine to perform silence detection on the received broadcast stream; and

control the recording of the broadcast media stream on the basis of the detection.

14. The method of claim 1 , further comprising:

initiating recording of the broadcast media stream at the media device; and

stopping the recording without saving if no command to continue is received from a user interface of the media device within a predetermined time period.

15. The method of claim 1 , wherein the service transmission is received at the media device over a radio interface of a cellular telecommunication system.

16. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus to perform at least the following,

receive via a broadcast channel, at a media device, a broadcast media stream transmitted by a broadcast system, and concurrently receive via a communication channel, at the media device, a service transmission at a timing synchronized with a timeline of contents in the broadcast media stream, the service transmission comprising information about the contents of the broadcast media stream;

detect when the information comprises data corresponding to given one or more search parameters; and

determine, independently from a user of the media device, to record the broadcast media stream at the media device on the basis of the detection.

17. The apparatus of claim 16 , wherein the apparatus is further caused to:

receive the search parameters from a user of the apparatus;
