HD-SDI Inputs and Outputs
The Imagestore HDTV inputs accept serial HD-SDI video streams
conforming to the following standards:
♦ 1920 x 1080i/59.94 Hz SMPTE 274M 1998
♦ 1920 x 1080i/50 Hz SMPTE 274M 1998
♦ 1280 x 720/59.94 Hz SMPTE 296M 2001
♦ 1280 x 720/50 Hz SMPTE 296M 2001
through screened 75Ω BNC connectors. There is a Return Loss of < -15dB,
over the range 5MHz to 1500MHz. Each input circuit is provided with
automatic adaptive equalisation circuitry suitable for cable lengths of at least
80 metres (of Belden 8281 or equivalent coaxial cable).
Both HD-SDI outputs are to the same data structure and physical standard as
the inputs and provide output amplitudes of 800mV (± 10%).
Imagestore HDTV will delay the video path by no more than one line,
excluding any in-circuit DVE delay.
Power Requirements
Imagestore accepts power from a 110V or 230V, 60Hz or 50Hz, AC mains
supply. The mains supply input fuse is a T2A5 (2.5Amp Anti-surge) and
should always be replaced with a fuse of the same rating.
Interfaces
The Imagestore employs five types of control and image interfaces and a
summary of these is given in the following table.
