IQMDMO SECTION 40b IQMDMOOPS 150403 Version 1 Issue 2 40b.1 IQMDMO MPEG-2 Decoder with MOLE™ Output Module Description The IQMDMO is a full broadcast quality MPEG-2 decoder with MOLE™ output. It supports multi- standard 4:2:2 and 4:2:0 video decoding (up to MP@ML and 4:2:2 Profile@ML) on dual SDI outputs. The decoder accepts both single and multi-program transport streams (SPTS and MPTS) on two selectable Asynchronous Serial Interface (ASI) inputs. Frame-accurate genlocked output synchronization is featured as standard. Audio decoding of MPEG-1 Layer II and direct pass-through of AC-3 streams are supported by up to four unbalanced digital audio outputs. Teletext received to DVB standard EN 300 472 may be inserted into the VBI of the SDI output in accordance with ETS 300 706. Standardized as SMPTE 319M and 327M, MOLE™ Technology enables an MPEG-2 decoder to pass the encoding decisions from the original encoding to any subsequent encoder through the SDI signal. MPEG signals decoded with the IQMDMO can then be manipulated in the same manner as SDI video, allowing edits, wipes, crossfades and digital effects to be performed. It is then possible to re-encode with a MOLE™- compliant encoder using the original coding decisions with no loss of quality. It also enables transcoding to be more transparent and flexible enough to handle any constant or variable bitrate input, with 4:2:2 or 4:2:0 video. The IQMDMO accepts all current standard definition formats used by DVB, ATSC and ARIB. Its reduced size provides a highly cost-effective solution for both single and multi-channel video decoding where space is limited (e.g. OB trucks). Multi-channel capability makes the decoder fully suited for broadcast play-out operations where several MPEG feeds need to be switched and mixed along with uncompressed sources using conventional digital video studio equipment: contribution, distribution, head-end, regional affiliate systems, etc. RollCall remote control and logging system is available as standard, allowing video and audio fault or warning conditions to be reported and logged over RollCall. As standard, a full frame genlocking synchronizer allows the outputs to be locked to an external analogue reference to allow simple installation. Alternatively, the outputs can be locked to the incoming MPEG time reference. The card features four unbalanced digital audio outputs (AES/EBU). The audio circuit is capable of decoding up to four MPEG1 Layer I/II (ISO 13818- 3) simultaneously. It can also pass-through up to four Dolby Digital AC-3 streams (SMPTE 340M). Any of the four AES audio outputs can be selected for embedding into the output video in accordance with SMPTE 272M. The two ASI input interfaces can be configured to automatically select between the two inputs upon input signal loss (e.g. broken cable) as well as automatically invert the ASI input(s) in cases where the ASI signal(s) has become inverted by some external process REAR PANEL VIEW C
