Patent ID: 8305496

Claim:
A scaling process system comprising a replay apparatus and a video output apparatus which are connected via a HDMI, wherein each of the video output apparatus and the replay apparatus respectively comprises a between-pixel interpolation method table for deciding a superiority/inferiority of a between-pixel interpolation method which is used when carrying out a scaling process in the scaling process system, wherein the video output apparatus comprises; a request signal transmission device to transmit a request signal for requesting between-pixel interpolation method information which indicates the between-pixel interpolation method which is used when carrying out the scaling process in the replay apparatus to the replay apparatus, a between-pixel interpolation method information receiving device to receive the between-pixel interpolation method information which is returned from the replay apparatus in response to the request signal, a determining device to determine which of between-pixel interpolation method information of the replay apparatus or between-pixel interpolation method information of the video output apparatus is more high-performance based on the between-pixel interpolation method table by comparing the between-pixel interpolation method information of the replay apparatus which is received by the between-pixel interpolation method information receiving device with the between-pixel interpolation method information of the video output apparatus, a deciding device to decide an apparatus in which the between-pixel interpolation method information which is determined as being high-performance by the determining device is stored as an apparatus to be used for the scaling process, and a control device to control the apparatus which is decided by the deciding device so as to carry out the scaling process, and wherein the replay apparatus comprises; a request signal receiving device to receive the request signal which is transmitted by the request signal transmission device of the video output apparatus, and a between-pixel interpolation method information return device to return the between-pixel interpolation method information of the replay apparatus to the video output apparatus in response to the request signal.
