In addition, there are four analog SPOT outputs that can be used to monitor live camera inputs. For video record, the TW2880 supports 16-channel real time and non-real time recording with flexible frame rate and resolution over 27MH, 54MHz and 108MHz clocks. The record output ports support BT.656, BT.1120 and BT.601 data formats. Special record modes such as mixed frame and mixed field switching modes are also supported. Record output stream can be in field or frame interleaved format. The playback input ports support BT.656, BT.1120, BT.601 and 16-bit digital RGB data formats. Up to 16 channels of playback video are supported. Other key features of TW2880 include triple 16-bit bitmap OSG windows, font OSD, channel ID encoder/decoder, and motion detector.
