Video Inputs and Outputs
Video Inputs
The PIX 240i accepts SDI or HDMI video; the PIX 220i only accepts HDMI video. Both recorders will
accept either high-definition or standard-definition rates.
PIX recorders do not accept analog video signals. See the specifications section for a complete list of sup-
ported frame rates.
HDMI
The PIX 220i and PIX 240i accept HDMI version 1.4a video and audio. Supported video resolutions
and rates are listed in the specifications section. PIX recorders accept up to 10 bit, 4:4:4 video over
HDMI. Two-channel digital audio embedded in the HDMI stream (32 kHz – 192 kHz) is always re-
sampled to 48 kHz when connected to a PIX recorder.
720p30/29.97, 720p25, and 720p24/23.976 are not supported on the HDMI input or the HDMI output.
HDCP copy protection prevents direct digital-to-digital copying of copyrighted material. Protected
DVDs, Blue-Rays and streaming content with HDCP encryption is not valid content and will be ignored
by the PIX recorder.
SDI
The SDI input on the PIX 240i accepts video with embedded audio (up to eight channels) and em-
bedded SMPTE timecode. This connection accepts digital video up to 12-bit, with up to 4:4:4 color
sampling. Unlike the HDMI interface, which auto-negotiates rates between devices, what comes out
of a camera’s SDI output is received by the PIX recorder with no auto-negotiation or sample rate
conversion.
The PIX 240i supports 3G-SDI single link, but not dual-link HD-SDI.
Timecode over SDI is not available when recording in standard definition
Video Outputs
The video outputs on the PIX recorders contain incoming video when idle and while recording;
during playback they contain the playback video. Both HDMI and SDI outputs are active simul-
taneously on the PIX 240i. This allows for conversion from SDI-to-HDMI and HDMI-to-SDI. The
video stream contains embedded audio (up to eight tracks) as defined by the Setup Menu option
Audio
Audio Input
. Both the SDI and HDMI outputs contain the same embedded audio.
Except during playback, the resolution and frame rate of the output stream is configured in the
Setup Menu option
Video
File Resolution/Rate
. During playback, the resolution and frame rate of
the output stream is determined by the playing video file.
The HDMI outputs of the PIX recorder use the HDMI 1.3a protocol. HDMI output signal is always
10-bit, 4:2:2.
