LaserCube solves audio/video synchronization issues for Defense Connect Web conferencing
LaserCube solves Defense Connect Web conferencing audio/video synchronization issues over distance
Adobe™ Defense Connect is a popular web conferencing application used by the military intelligence community. Cubix LaserCube with PCI Express (PCIe) bus extension technology solves the audio / video synchronization (sync) problems with web conferencing applications that are running on blade PCs, typically using thin client desktops.
LaserCubes and thin client desktop appliances provide similar benefits. Both allow the data storage and processing hardware components to be locked up in the data center for better security. Both provide small desk footprints, with reduced noise and heat in the work areas.
For web conferencing, trying to send bi-directional audio and video using thin client IP packets to the desktops creates a choppy disjointed effect where sound and picture become out of sync and distorted. This is most noticeable with two-way (watch & move / listen & speak) Web conferencing using applications like Adobe™ Connect® Pro or Defense Connect.
The technical reason is simple. Thin clients compress and packetize video changes and audio for the thin-client server. Thin-client server un-compresses and un-packetizes the video changes and audio, and then re-compresses and re-packetizes it for the recipient’s thin-client server. Thin-client server un-compresses and un-packetizes the video changes and audio, and then re-compresses and re-packetizes it for the receiving thin client. The packetized traffic moves as best it can across collision-based, enterprise media, but the transmitting server may have to re-transmit several times, which means that video and audio become separated and are often no longer synchronized. The more participants you add to a Web conference means that many more opportunities for delays—and that much more out of sync are video and audio.

LaserCubes, by contrast, provide a no-compromise approach to delivering graphics and sound over distance with no delays that adversely affect audio and video output such as mouse jerkiness, loss of resolution, choppy fragmented video output, and sound that is not synchronized with video.
Like networked PCs, LaserCubes have NVIDIA graphics processing units (GPUs) with embedded high-density (HD) audio. The GPU synchronizes video and audio, and then the host computer packetizes it together as network traffic for the recipient, who receives synchronized video and audio. Thanks to the PCIe bus link, audio and video controllers in the LaserCube desktop appliance are local to the users directly connected to LaserBlade PCs that send uncompressed, synchronized audio and video packets.
LaserBlade and LaserCube together are the perfect solution for secure web conferencing applications.
