Method and system for backward recording
It is provided a method for backward recording in a device having a time-shift function, including: launching the time-shift function, when a user select one program, to record the program on a time-shift buffer; receiving an instruction to record a scene backward within the program being viewed by a user: acquiring information on the program from EIT(Event Information Table); determining a type of the program on the basis of the information; setting a duration of the backward recording dependent on the type of the program; and copying a data, which is stored in the time-shift buffer and corresponds to the duration backward from the time of receiving the instruction, in a storage of the device.
1. A method of storing data, the method comprising:
upon selection of a broadcast channel in a device for reception of broadcast channels, automatically storing of data from said broadcast channel received by said device in a first memory while said selected broadcast channel is being received;
receiving an instruction to store, in a second memory, a previously received part of an event on said selected broadcast channel;
obtaining, in response to the instruction to store, a duration of the previously received part to store in the second memory, said duration being dependent on an event type of said event on said selected broadcast channel when receiving the instruction, said event type being obtained from service information related to the selected broadcast channel; and
selectively, in response to the instruction to store, copying a portion of the data from the first memory to the second memory, an end of the portion corresponding to a time of receiving the instruction and a beginning of the portion corresponding to the duration backward from the time of receiving the instruction.
2. The method according to claim 1 , wherein the instruction is received through a recording button.
3. The method according to claim 1 , wherein the service information comprises an Event Information Table.
4. The method according to claim 1 , further comprising receiving an instruction to playback the data stored in the second memory via a recording playback button.
5. A device for storing data, comprising:
a first memory;
a second memory;
a processor configured to:
upon selection of a broadcast channel in a device for reception of broadcast channels, automatically store data from said broadcast channel received by said device in said first memory while said selected broadcast channel is being received;
receive an instruction to record, in said second memory, a previously received part of an event on said selected broadcast channel;
obtain, in response to the instruction to record, a duration of the previously received part to record in the second memory, said duration being dependent on an event type of said event on said selected broadcast channel when receiving the instruction, said event type being obtained from service information related to the selected broadcast channel; and
selectively, in response to the instruction to record, copy a portion of the data from the first memory to the second memory, an end of the portion corresponding to a time of receiving the instruction and a beginning of the portion corresponding to the duration backward from the time of receiving the instruction.
6. The device according to claim 5 , further comprising a user input module comprising a recording button, the processor being further configured to receive the instruction through the recording button.
7. The device according to claim 5 , wherein the processor is further configured to obtain the event type from an Event Information Table comprised in said service information.
8. The device according to claim 5 , wherein the processor is further configured to receive an instruction to playback the data stored in the second memory via a recording playback button.
9. A computer program product for a programmable apparatus, the computer program product comprising a sequence of instructions for implementing the method according to claim 1 , when loaded into and executed by the programmable apparatus.
10. A non-transitory computer-readable medium comprising a computer program product recorded thereon and capable of being run by a processor, including program code instructions for implementing the method according to claim 1 .
