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 pre-determined 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?

14

Support for TelePresence Server

Support for direct integration with CUCM

SIP B2BUA puts Conductor in the signaling path

Why add another box?

Improvements to logging

Limited TMS scheduling support

Allows CUCM multipoint resources

to be shared for both ad hoc and

rendezvous conferences

Advanced features like

optimized resources on the

TS are possible

Central point of

management for all

conferencing needs

TelePresence and traditional UC (telephony and SD video) all collapsed on a converged UC Manager cluster. Former TANDBERG endpoints predominantly still on VCS Control

Full native any-to-any interoperability between all endpoints and bridges. Ad hoc bridges under Conductor on UCM, scheduled bridges still on VCS Control

Product functional overlap diminished; roles clarified but not all consolidation fully realized yet

Homogenized dial plans: both numeric and alphanumeric now fully supported across most of the portfolio

Provisioning, management, monitoring coming together – Prime Collaboration growing in functionality

Feature and User Experience consistency across the portfolio getting better and better

New compelling solutions like WebEx-enabled TelePresence

Architectural Evolution 1st Half CY 2014

18

All endpoints and infrastructure collapsed onto a converged UC Manager call control with Expressway (C&E) for Remote & Mobile Access to UCM, B2B and WebEx/Cloud-enabled TelePresence connectivity and 3rd-party interworking

Multiparty bridging for audio and video, for all types of conferences now trunked through UC Manager (TMS scheduled resources still separate from Conductor ad hoc resources)

Jabber now available on Windows, Mac, iOS and Android using Expressway for VPN-less access to UC Manager and related UC services (directories, presence, visual voicemail)

Video now a table-stakes feature: infused in a growing number of applications like Cloud-enabled TelePresence, Unity messaging, Contact Center with new enabling technologies like Jabber Guest and WebRTC, H.265 and Scalable Video Coding (SVC)

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


Scalable Video Coding

Encode a high fidelity source using multiple layers of increasing fidelity

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

25

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


Spatial Scalability

Supported in H.264 SVC (Annex G)

Planned in H.265 SHVC (in progress)

H.265 SHVC will support a base layer of

H.265 HEVC or H.264 AVC

Drawbacks: interoperability, bandwidth overhead

MediaSense


MediaSense

Video on Hold (VoH)

In UC Manager, MediaSense server(s) can be defined as Video on Hold resources and assigned to Media Resource Groups and used with Native Hunt Groups queuing

Video in Queue (ViQ)

In UCCE, MediaSense server can be defined as Video on Hold and Video in Queue servers and integrate into the Finesse agent desktop

When a caller is in queue waiting for an agent

When an agent places a customer on hold

Video Greetings

In Unity Connection, MediaSense server(s) can be defined as storage/playback servers

When a call is forwarded (busy / no answer) to Unity voicemail caller will now “see” your voicemail greeting

Recording of video messages is planned for a future release

Video On Hold, Video in Queue and Video Greetings in Unity Connection Voicemail
