Abstract

A switched input video device has a switched input, video improvement circuitry and/or transcoder circuitry, and a switch for communicating a switched input to at least one of the video improvement circuitry and the transcoder circuitry.

Claims

1. A switched input video device comprising:

a switched input

a video improvement circuit; and

a switch for communicating the switched input to the video improvement circuit, wherein the switch is operable to sense a presence of a signal on the switched input and communicate the switched input to the video improvement circuit in response to the sensed signal,

wherein the video improvement circuit is configured to;

receive a video signal that complies with a standard;

sense one or more blanking portions of the video signal; and

alter the video signal during a portion of the video signal other than the one or more blanking portions, wherein the altered portion of the video signal does not comply with the standard and the alterations improve a characteristic of the video signal.

2. The switched input video device as recited in claim 1, further comprising an internal media player and wherein the switch selects either the Internal medial player or the switched Input.

3. The switched input video device as recited in claim 1, wherein the switch is externally controlled.

4. The switched input video device as recited in claim 1, wherein the switch is remotely controlled.
