Definitions

• the present invention relates to a video recording device comprising a time shifting unit.
• the broadcast signal received by means of a receiver is stored on a main memory by being recorded by user command and can be watched again whenever desired.
• broadcast signal recording feature as well as time shifting feature are present.
• the time shifting unit enabling the realization of the time shifting process records the real time broadcast signal into a volatile memory by the broadcast stop command of the user and enables the user to watch the time-shifted content on the volatile memory when the user desires to resume the program. Since the volatile memory capacity is limited, the data on the volatile memory is deleted when the user returns to the real time broadcast signal.
• video recording devices having a time shifting unit that is continuously active are also present. In these devices, the broadcast signal is continuously recorded in the background. Since the volatile memory is limited once again, the time-shifted content that can be recorded retrospectively is limited to an amount determined by the manufacturer.
• the time-shifted content recorded by means of the time shifting unit is deleted from the volatile memory after a certain time or by the command of the user to shift to the real time broadcast signal, and this content cannot be accessed when desired to be watched later.
• the time shift means records continuously.
• the recording of data in the time shift recording region is stopped, and the recording of data in the permanent recording region is started.
