|
||||
accept analogue video from a wide variety of sources such as
|
||||
broadcast, DVD players, cameras and video cassette recorders, in
|
||||
either NTSC, PAL or HD format and still occasionally SECAM, separate
|
||||
it into its component parts, luminance and chrominance, and output
|
||||
it in some digital video standard, with appropriate embedded timing
|
