Hewlett-Packard is rolling out a host of new video collaboration technologies, unveiling its additions in the middle of a week that has seen more than its share of communications announcements from top-tier vendors.

Cisco Systems, kicking off its Collaboration 2010 Summit Nov. 15, introduced its efforts to integrate its visual communications technologies with a new desktop virtualization effort. At the same time, Cisco officials announced that they were video-enabling all of their endpoints and rolling out new TelePresence offerings.

Microsoft Nov. 17 took the wraps off Lync 2010, the latest iteration of its Office Communications software suite that is the company’s latest push into the highly competitive UC (unified communications) market. Along the way, a number of other vendors, including telepresence vendor Polycom, announced support for Microsoft’s offering.

Smaller vedors also are working to gain traction in the space. Mitel Nov. 15 introduced its Freedom architecture , a cloud-based solution designed to bring an array of communications capabilities to enterprises, and such supporting offerings as Mitel AnyWhere, desktop virtualization integration with VMware View, and expanded UC support for Google Android, Research In Motion and Apple devices.

Now comes HP, which on Nov. 17 rolled out software offerings that will enable enterprises to bring high-definition video communications anywhere. It will allow businesses that have gotten used to the high-quality immersive experience of HP’s Halo telepresence products to get a similar one through their desktops or other devices, according to Darren Podrabsky, marketing manager for HP’s Visual Collaboration business.
