VIDEO SIGNAL PROCESSING DEVICE AND VIDEO SIGNAL PROCESSING METHOD

WIPO Patent Application WO/2011/114633

A1

Disclosed is a video signal processing device (100) for processing a video signal in such a way that an output signal is output. The output signal is for an image which has a size that is different from an image displayed by a video signal that is input. The video signal processing device (100) is provided with: a decoder (110) for decoding an encoded video signal and generating a decoded signal; a decoding buffer (111) for connecting to the decoder (110) and storing the decoded signal generated by the decoder (110); a decoded signal modification unit (120) for reading out the decoded signal, which has been modified in such a way that the video effective period within one vertical synchronization period of the decoded signal has the same values as the video effective period within one vertical synchronization period of the output signal, from the decoding buffer (111) as a modified decoded signal, and for outputting the modified decoded signal that is read out; and an NR/IP conversion unit for reducing noise in the modified decoded signal and also for performing IP conversion of the modified decoded signal, by writing the modified decoded signal to memory and reading the modified decoded signal out from memory.
