It incorporates the latest Silicon Architectures to surpass the barriers inherent in previous-generation approaches. The Selenio SEL-1ENC2 contribution encoder works in both and 8 and 10 bit modes, provides compression of a single video signal — using either the MPEG-2 or H.264 standards — and compression of up to eight streams of audio supporting a variety of common algorithms, as well as the processing of associated VBI, VANC, and Serial Data. The Encoder is built with the latest technology in Compression and provides a high level of compatibility with the Selenio SEL-1DEC2 contribution encoder module and other industry encoders. SEL-1ENC2 and SEL-1DEC2 used in pair can deliver a Low Latency of 250ms guaranteed end to end, making a perfect contribution solution for Interview or sports applications. Optimized for contribution applications — including studio-to-studio post production, stadium, surveillance, or satellite uplinks— the Selenio SEL-1ENC2 contribution encoder delivers a full complement of features in a space- and power-efficient footprint, and resets the standard for simplicity in the H.264 era. The Selenio encoder module supports all popular video formats from standard definition (SD) to high definition (HD) to 1080i. Supported video and audio formats and compression standards can be upgraded in the field, providing a cost-effective expansion path for any facility. Up to eight stereo pairs of audio can be supported, and a variety of audio compression options are available, including Dolby® AC-3 2.0 and 5.1, MPEG-1 Layer 2, AAC-LC stereo and 5.1, HE–AAC stereo and 5.1, and Dolby® E. All audio can be presented to the encoder as embedded on SDI, or as separate AES inputs. Front Module Connectivity. The SEL-1ENC2 encoder application module is interconnected with the two controller modules for SDI/ASI, 100Base-T for control and monitoring and 1000Base-T for data applications. An internal digital reference also is available from each controller. Back Module Connectivity The SEL-1ENC2 encoder application module offers two choices for back module external connectivity — one with HD-BNC electrical connections for input and output, and one with an SFP optical input with HD-BNC outputs. Both back modules provide AES-3 connections by utilizing HD-BNC connectors and a GPI/serial port connector. SDI and ASI interfaces utilize a Belden-type 1505A, 1694A or 1695A cable with HDBNC connectors, and AES-3 interfaces utilize a Belden-type 1855 cable with HD-BNC connectors. A cable removal tool is provided for these types of HD-BNC connections. For optical input connectivity, an SFP receiver can be added to the appropriate back module.
