Abstract:
1. A video signal processing apparatus comprising: a receiving portion that receives a broadcast signal from a cable television station; a first resolution conversion portion, connected to the receiving portion, that selectively converts a resolution of a video signal based on said broadcast signal to both low definition and high definition; a first analog video output portion, directly connected to said first resolution conversion portion that outputs an analog video signal, a resolution of which is converted by said first resolution conversion portion, to a display; a second resolution conversion portion that converts the resolution of said video signal based on said broadcast signal to only low definition, and outputs the converted low definition to the display, wherein the second resolution conversion portion is separate from the first resolution conversion portion; a digital video output portion includes a High-Definition Multimedia Interface (HDMI) connection portion directly connected to said first resolution conversion portion, the HDMI outputs a digital video signal, a resolution of which is converted by said first resolution conversion portion, to said display; and a control portion that determines whether or not connection between said digital video output portion and said display is in an on-state, the control portion further determines whether the broadcast signal includes a signal for restricting output of the video signal of high definition, wherein said control portion controls said first resolution conversion portion to convert said video signal to said digital video signal of said high definition and controls said digital video output portion to output said digital video signal of said high definition in response to determining by the control portion that the connection between said digital video output portion and said display is in an on-state and said broadcast signal includes the signal for restricting output of said video signal of said high definition and copyright protection function is effective, wherein the signal for restricting output of said video signal of said high definition is included in Copy Control Information (CCI) bits transmitted in the broadcast signal.
