1 You can install and use Cisco Unified Videoconferencing Desktop Conference Client on computers using the Microsoft Windows and Mac. For the Mac OS, Cisco Unified Videoconferencing Desktop supports limited functionality allowing users to watch webcasts and recordings but not to participate in live meetings. 2 Used for streaming on Mac OS X operating systems.

In a Desktop client, a CPU auto-detect mechanism is used to define whether this client is capable of performing interactive conferencing using a high definition or standard definition service, and at what rate the client can send and receive video.

The CPU estimation is based on the number of physical cores available on the client computer and is performed using this formula:

EstimatedCPU = NumberPhysicalCore x SpeedOfEachCore

Desktop uses the EstimatedCPU value to define what frame rate to allow for each resolution. shows framerates that Desktop sends to clients.
