Title:
VIDEO RECORDING APPARATUS
Document Type and Number:
Japanese Patent JP2009159270
Kind Code:
A
Abstract:

To actualize video recording of a digital broadcast with a more simplified structure by selecting the digital broadcast in the case where the broadcast programs of the identical contents is received simultaneously with a video recording apparatus that receives both analog and digital broadcasts.

A DVD recorder 1 includes a receiving unit 2, an encoding unit 3, a recording/reading unit 4, a signal processing unit 5, an output unit 6, a manipulating unit 8, and a control unit 9. The control unit 9 executes the processes 91 to 96. The receiving unit 21 receives both analog and digital broadcast programs and stores respective frames in buffers. The encoding unit 3 includes a read control unit and an encoder. The read control unit controls the read timing from the buffer. The encoder is constituted to output time-series differential images. When the control unit 9 executes the determining process 96, the read control unit alternately reads the analog and digital image signals and outputs the signals to the encoder. The control unit 9 determines whether the analog and digital broadcasts have the identical contents or not from the differential images output from the encoder.
