• 8x8 transforms which more effectively compress images containing
areas of high correlation
These compression algorithms demand higher computation requirements,
which are offered with the dedicated hardware available in Scopia

Solution components. Using H.264 High Profile in videoconferencing
requires that both the sender and receiver's endpoints support it. This is
different from SVC which is an adaptive technology working to improve
quality even when only one side supports the standard.
H.320 H.320 is a protocol for defining videoconferencing over ISDN networks.
H.323 H.323 is a widespread set of protocols governing the communication
between endpoints in videoconferences and point-to-point calls. It defines
the call signaling, control, media flow, and bandwidth regulation.
H.323 Alias See Alias on page 49.
H.350 H.350 is the protocol used to enhance LDAP user databases to add video
endpoint information for users and groups.
H.460 H.460 enhances the standard H.323 protocol to manage firewall/NAT
traversal, employing ITU-T standards. Endpoints which are already H.460
compliant can communicate directly with the PathFinder server, where the
endpoint acts as an H.460 client to the PathFinder server which acts as an
H.460 server.
HD A HD ready device describes its high definition resolution capabilities of
720p, a video resolution of 1280 x 720 pixels.
High Availability High availability is a state where you ensure better service and less
downtime by deploying additional servers. There are several strategies for
achieving high availability, including deployment of redundant servers
managed by load balancing systems.
High Definition See HD on page 54.
High Profile See H.264 High Profile on page 53.
HTTP The Hypertext Transfer Protocol (HTTP) is an application protocol for
distributed, collaborative, hypermedia information systems. HTTP is the
foundation of data communication for the World Wide Web.
Hypertext is structured text that uses logical links (hyperlinks) between
nodes containing text. HTTP is the protocol to exchange or transfer
hypertext.
HTTPS HTTPS is the secured version of the standard web browser protocol HTTP.
It secures communication between a web browser and a web server
through authentication of the web site and encrypting communication
