VOSCOM Fiber Optic SDI / DVB-ASI / HD-SDI Transmission series support digital video signals ranging from uncompressed SDI, DVB-ASI or HD-SDI over optical fiber. The Fiber Optic Transmission products can also transmission accompanying signals such as analog audio, digitized AES/EBU audio and control data.
Broadcast-related fiber optic applications will continue to expand with the further development of new and advanced transmission systems. VOSCOM's technology is geared to meet the demands of an ever-growing Video/Audio/Data communication traffic industry.
our fiber optic transmission systems is the source for customers who are increasingly seeking multi-faceted studio broadcast quality capabilities and services. VOSCOM'S advanced technology is reshaping the broadcast industry with the next generation of optical digital transmission.
Serial Digital Interface (SDI), standardized in ITU-R BT.656 and SMPTE 259M, is a digital video interface used for broadcast-grade video. For standard definition applications, as defined by SMPTE 259M, the possible bit rates are 270 Mbps, 360 Mbps, 143 Mbps, and 177 Mbps. 270 Mbps is by far the most commonly used; though the 360 Mbps interface (used for widescreen standard definition) is sometimes encountered. The 143 and 177 Mbps interfaces were intended for transmission of composite-encoded (NTSC or PAL) video digitally, and are now considered obsolete.
DVB-ASI (Digital Video Broadcasting — Asynchronous Serial Interface) is frequently used in satellite transmission, interfacility links, and telephony communications. DVB-ASI is designed to transport MPEG-2 video streams, primarily for television applications, at up to 270 Mbps. The electrical implementation of DVB-ASI is similar to serial digital interface (SDI). DVB-ASI is carried at a 270 Mbps line rate consistent with the SDI clock described in SMPTE 259M.
High Definition Serial Digital Interface (HD-SDI) is standardized in SMPTE 292M and provides a nominal data rate of 1.485 Gbps. For transmission distances greater than 100 meters, copper is not sufficient and fiber is required. Video formats supported are 720p and 1080i. Full 1080p 50/60 Hz formatting is supported by SMPTE 424M. SMPTE 424M is also commonly referred to as 3G-HD.
As with all VOSCOM products, these video devices carry a lifetime warranty. Please give our sales department an E-mail: sales@voscom.com or Feedback with any questions. We would be delighted to contact with you.
