XVD Professional HD-TX2500 HD/SD Video and Audio Encoder
Proven by broadcast leaders to outperform all other systems.
Achieve robust and reliable HD-SDI 1080i 4:2:2 real-time low-latency feeds over traditional standard definition video microwave/ satellite links or inexpensive IP networks
The HD-TX2500 provides DVB/ASI and IP network output for highly efficient, low-cost live streaming of XVD-HD/SD data packets. Designed for DENG and other live mobile applications, it supports HD-SDI and SD-SDI as input and output (with its associated HD-RX2500 decoder), making it compatible with digital studio and post-production facilities. Users can select from HDTV (1080i or 720p) and SDTV (NTSC or PAL) standards. Compact (80% smaller than conventional HD encoders) and versatile, the HD-TX2500 offers real-time compression of HDTV video at 3-15Mbps and SDTV video at 500 Kbps to 5.0 Mbps, and support 4:2:2 or 4:2:0 chroma format in all resolutions. Stream HD video at SD bitrates, or stream SD video at sub-T1 bit-rates.
The XVD audio/video streaming system consists of the HD-TX2500 Encoder and the HD-RX2500 Decoder. This high-performance system offers increased operational flexibility by providing exceptional quality A/V streaming where bandwidth permits, and high quality A/V streaming where bandwidth is limited. Front panel and web-based command and configuration extend operational flexibility even further.
In addition, the XVD Professional HD-TX2500 is built into the new second generation NewsHound IISM backpack DENG encoder and RF transmitter.

XVD is the world’s most advanced realtime video compression technology. Years of development and field testing supports the XVD codec design, providing much higher performance and efficiency than other block-based real-time video compression systems. XVD’s patented video codec is optimized for the human visual system, and adds several unique features including: Automatic Scene Change Detection; Object Motion Estimation; plus CBR/VBR data rate control to improve video quality at dramatically lower data rates. The XVD audio codec also provides high performance at significantly lower data rates, allowing more audio channels to be carried in any chosen bandwidth.
LOW LATENCY
Enjoy both high performance and encode-decode system latency of only 200-300 milliseconds.
BANDWIDTH EFFICIENT
Provides a competitive alternative to VC1 and AVC at a more affordable price
NO ROYALTIES
Unlike other compression standards, users of XVD products never pay a royalty of any kind.
