Q: What is XVD's "core technology?"
A: XVD's primary technology base is a highly efficient encoder/decoder ("codec") algorithm designed for several computing platforms, and including a very efficient, low power, small footprint DSP implementation. Q: How is XVD™ technology different than, say, MPEG-2 or MPEG-4? A: Like MPEG, XVD™ technology is a DCT-based codec. Unlike MPEG, XVD™ technology is a proprietary implementation and therefore not subject to MPEG's limitations and constraints. The XVD codec has been proven to be more efficient and delivers superior video and audio at lower data rates, and is especially effective with motion video. The same XVD codec is used for low-bandwidth, SD applications and higher-bandwidth HD applications. Q: What are XVD's products? A: XVD designs, builds, tests and distributes two main product lines based on XVD™ core technology. These product lines are known as " XVD™ Enterprise" and " XVD™ Professional." The XVD™ Professional product line is, as the name implies, directed at the professional digital media industry. XVD™ Professional products support digital input and output in both HD and SD, with transmission over both Ethernet and ASI interfaces. XVD™ Enterprise supports analog SD input and output over Ethernet media. Both provide an efficient, effective platform for streaming real-time audio and video. Several software applications are available to extend the enterprise environment. Q: Who is using XVD's products? A: XVD™ Professional and XVD™ Enterprise products are being used in various applications by major U.S. and global TV networks, as well as independent TV stations. XVD products are also being used in the defense, video surveillance and homeland security arenas. XVD™ technology was initially deployed in Japan, where it found immediate acceptance at the major networks and numerous local TV stations in both HD and SD applications. Q: Will XVD™ technology work over T1 (E1) lines? A: Yes, transmitted audio/video quality at "sub-T1" speeds (1.4 Mbps or less) is acceptable for backhaul and broadcast applications, and has proven to be particularly valuable for remote news gathering and other real-time content acquisition. Q: Will XVD™ technology work over BGAN? A: Yes, XVD™ Enterprise has been tested over "live" BGAN connections at real-time, streaming data-rates of 64, 128, 256 Kbps and in "best effort" 512 Kbps. Q: What is "ProXVD?" A: ProXVD™ combines a basic network analysis tool with a powerful forward error correction (FEC) engine that is similar to ProMPEG, and is equally effective. ProXVD™ allows XVD products to be "fine-tuned" to the characteristics of an IP network for maximum performance and efficiency. Q: What is the latency for an encoded XVD™ technology stream? A: Latency will vary depending on the transmission medium; Ethernet or ASI, and wireless/satellite or Telco link. Total, end-to-end latency (encode/decode) for XVD™ Professional products can be as low as 240 milliseconds, and can be higher if the application requires additional FEC due to network instability. Q: Is the XVD™ ASI stream compatible with transport stream switches and other devices? A: The encoded ASI stream is transported in the user data section of transport stream packets, and will pass through TS switching equipment with no problem. The XVD™ stream contains PID and PCR, but is otherwise not decodable by MPEG equipment. This provides an added level of security for those in need of high security video links. The XVD™ ASI interface is compatible with standard ASI modulators and multiplexers. Q: Can I remotely configure XVD products? A: All XVD products support an elegant web-based user interface that is robust and simple to use. On condition that the XVD product is accessible on a customer’s IP network, a user or technical support person can log in and change settings easily. Access to the configuration interface is account and password protected. XVD™ Professional products have an easy-to-use front panel LCD interface, in addition to the web-based GUI. Q: What is a "NewsHound IISM" A: NewsHound IISM is an innovative, lightweight, battery powered system combining the TX-2000 HD/SD encoder packaged with a 2-Ghz or 7-Ghz microwave transmitter, battery pack and antenna in a durable and comfortable backpack platform. NewsHound IISM is designed to allow news teams unprecedented access to news events in real-time, extending – or even replacing – the satellite truck. News crews can now travel up to 3 miles (5 kms) from the truck to cover a breaking news story at close range where many times a truck cannot enter or access. NewsHound IISM is also finding application in sports and other live event broadcasts, as well as in homeland security, public safety and defense video where there is an operational need for HD or SD wireless cameras. XVD™ technology completely integrates the encode/transmit/receive/decode functions for an end-to-end, easy to deploy solution. Q: How is XVD support? A: XVD is fast gaining a reputation for setting the “gold standard” in customer support and service. XVD is committed to provide best-in-class customer service.
