Network Electronics, who acquired Video Products Group (VPG) of Oxnard California earlier this year and is now known as Network Electronics/VPG is introducing several new modules in the newly combined Company’s Ventura range of advanced products to facilitate the compression, transmission and economical transport of HD signals. The Ventura™ range was developed VPG and targets the telco and broadcast markets.

These product enhancements give Network Electronics/VPG's customers a greater ability to meet the challenges of transporting high definition signals and managing the diverse mix of legacy and emerging signal formats. Their compression and long distance interfaces extend the reach of the Ventura line, while universal conversion capabilities let customers adapt to evolving regulatory requirements in metropolitan area networking.

JPEG 2000 VS901-TE-27 Encoder and VS901-TD-27 Decoder
The new VS901-TE-27 encoder and VS901-TD-27 decoder offers high-quality JPEG 2000 compression of HD-SDI signals, qualifying them for transport over widely deployed 270Mbps networks. These modules also allow HD to be stored on SDI servers and tape decks and to map HD into SONET / SDH and IP networks using VS811 cards.

Key Features

* Artifact-free compression – no blocking, tiling or motion dependence
* Visually lossless compression to a 15:1 compression ratio; near-mathematically lossless compression to a 2.5:1 ratio
* Set compression explicitly or by selecting maximum available transport bandwidth
* Multiplexes audio into the transport stream, either pre-embedded into the HD-SDI signal or by locally embedding from AES interfaces on the encoder
* Separate carriage of VBI information

8-Channel SONET/SDH VS811-SM-48 Multiplexer and VS811-SD-48 De-multiplexer
A new 8-channel SONET/SDH VS811-SM-48 multiplexer and VS811-SD-48 de-multiplexer - a single card solution for the multi-channel transport of 270Mbps signals and HD signals (with JPEG 2000 encoding) is also being debuted at the show. The module facilitates long distance transport of multiple SDI, ASI, SDTI signals and provides for network path diversity via optional dual SFP lasers at the transmit end, and dual SFP receivers with automatic switch-over at the receive end.

Key Features

* Mapping of 8 X 270Mbps onto OC-48c / STM-16c
* Buffered front panel monitor on MUX and DEMUX with channel selector switch to monitor inputs or outputs
* Jitter management restores degraded optical signal quality
* Selectable test pattern generator for each channel: color bars, PLL pathological, equalizer pathological and black field
* Auxiliary RS422 channel
* Small Form-Factor Pluggable (SFP) optics available in 1310, 1550, and any ITU CWDM or DWDM wavelengths

Universal Analog and Digital Video / Audio Adapter for Fiber Optic Transport
Also being introduced is a universal analog and digital video /audio adapter for fiber optic transport. The single card VS551-D-ADC (analog - digital converter and audio embedder) and VS551-D-DAC (digital-analog converter and audio de-embedder) is unique in the industry for its ability to adapt to any professional analog or digital video format.

Key Features

* Multiprotocol video interface to fiber networks
o NTSC / 4X audio (TV-1)
o SD-SDI
o HD-SDI
o DVB-ASI
o ATSC
* SD-SDI at 525 / 625; HD-SDI at 1.4835 / 1.485Gbps
* SFP optics for 1310, 1550, any ITU CWDM or DWDM wavelength
* Jitter management restores degraded optical signal quality
* Up to 4 channels of analog audio or direct-fed AES into SDTI
* Non-intrusive audio monitoring and level adjustment with built-in test signals (transmitter and receiver)
* Compatible with VPG element / network management
