Conferencing
Types of Conferences
 Ad hoc Conference
– Impromptu meetings, they are not scheduled beforehand ,nor require an administrator to
initiate them. Suitable for smaller, on-the-fly, meetings. A point-to-point call escalated to a
multipoint call is considered ad hoc.
 Rendezvous Conference
– Also called meet-me/permanent/static conferences, requires endpoints to dial in to a predetermined number. Often used for recurring meetings which involve different endpoints each
time.
 Scheduled Conference
– Provides a guarantee that endpoints and multipoint resources will be available at a certain
time. Endpoints join manually or are automatically connected by the multipoint resource.

Why do I need Conductor?
 Support for TelePresence Server
 Improvements to logging
 Support for direct integration with CUCM
 Limited TMS scheduling support
 SIP B2BUA puts Conductor in the signaling path
Why add another box?
Allows CUCM multipoint resources
to be shared for both ad hoc and
rendezvous conferences

Emergaing Video Technologies
H.265 or HEVC ( High Efficency Video Coding)


Higher compression efficiency
– Half the bandwidth for the same quality,
compared to H.264
– HD for everyone, everywhere: 720p30 <
500kbps
Higher resolutions: UHD 8k, 4k, 120 Hz
– H.264 Level 5.2: 4k (2160p) 60 Hz, 0.5
Gpixels/s
– H.265 Level 6.2: 8k (4320p) 120 Hz, 4.2
Gpixels/s (8x pixel rate)

Low complexity options
– Enables simpler decoders (mobiles)
– Tiles for memory bandwidth reduction

Backward compatibility
– H.264 base layer with H.265
enhancement layers

New target applications
Screen content (Class F test streams)
Still pictures (half the size of JPEG)
Parallel processing
Exploit multi-core hardware and reduce
latency
2D Tiles vs. 1D Slices, Dependent
Slices, and Wavefronts
Deblocking filter and CABAC entropy
coding are parallel-friendly
Cisco Public
Scalable Video Coding
 Encode a high fidelity source using multiple layers of increasing fidelity
Base Layer with lowest fidelity
360p 30Hz 0.5Mb/s
Spatial Enhancement Layer to increase resolution
720p 30Hz 1.0Mb/s
Temporal Enhancement Layer to increase frame rate 720p 60Hz 1.5Mb/s
Quality Enhancement Layer to increase bit rate
720p 60Hz 2.0Mb/s
 Main motivation is scalable conference servers
– Switching vs. transcoding, trading flexibility for scale and speed
 Other benefits include rate adaptation and error resilience
 Drawbacks include interoperability and lower coding efficiency
