Multimedia – The MostChallenging Issues

Status

Context and Perspective

Vision

www.bournemouth.ac.uk

• Convergence

1. Data – Web, etc – Obvious Limitations• Web 2 - Search engine per link

2. Voice• VoIP

• Quality of Service

3. Video

• YouTube, BBC I-Player, FaceBook

• Smart Phones - iPhone, Android, etc

• Bandwidth

www.bournemouth.ac.uk

Where are we withMultimedia?

• Convergence - Mobile MM experiencingsevere congestion

• Exponential global demand• 70% of Internet Bandwidth

• YouTube, BBC iPlayer, VOD streaming, P2P Games• Requirement for ‘Always, everywhere’ connectivity

• Wired Infrastructure –> Bandwidth for ‘free’

• 10/100 ‘Fast Ethernet’, Gigabit, Terabit

• 1000Gbps = 1Terabyte/s, 1000Tbps = 1 Petabyte/s

• ‘PetaWeb’, ‘ExaWeb, etc 3

• Future MM Internet Architecture: ‘Petra-Web’

• Local loop will be wireless and mobile• 4G / LTE / 5G …

• Merging of Data, Voice and Video• Access ‘everyone’, ‘anytime’, ‘everywhere’

• Bandwidth and Routing issues

• Content

• Semantic Modelling, ‘Smart’ Technology• ‘Adaptive Multimedia’ = Meta-data + Data-Analytics

Voicu Groza –The Most Challenging Issues in Multimedia - a User Perspective

• Antagonistic interests driven by business policies, politicaldirectives and heterogeneity of classes of users– The Bold BlackBerry is provided with the hardware for running

GPS navigation applications or MM VoIP software (such asSkype), but one cannot use it without permission from aprovider or enterprise, even for the own device.

– Third party applications cannot be developed or run on iPhonewithout Apple’s accept.

– Apple collects credit cards details of all iStore users even thoughone would not download but only free applications!

• Developers of MultiMedia (MM) devices address therequirements of internet or content providers and pay lessattention to users’ needs

• Currently, bandwidth limitation is controlled through plans’prices, by employing QoS tools

Voicu Groza –The Most Challenging Issues in Multimedia - a User Perspective

• MM can improve the interface betweenpatients and health care systems, but cannotreplace professional assistance with virtualMD’s (as some politicians may consider as aviable option).

• Vast majority of users accept mediocresolutions, as long as an acceptablefunctionality is provided

• Middleware system (vendor Beesmart)

• Video on Demand system (vendor Kasenna)

• Encryption system: Real Time Encryption system and Verimatrix system(vendor Verimatrix)

• Database system: Real Application Cluster (vendor Oracle)

• Statistic system (vendor Beesmart)

• Monitoring system (vendor Netvisor)

• Live TV

• Program search, Electronic Program Guide (EPG)

• TV Mosaic, Show TV recommendations

• Video on Demand (additional payment), Show VoD recommendations

• Instant recording (Program recording)

• Additional IPTV services (Radio, Internet, Games, Promotions, Info)

• VoIP options on IPTV (Phone Book, Phone, Caller ID, MWI)

BH Telecom’s IPTV Video receiving Headend

• H.264 (AVC) video compression

• Completely redundant system with automatic backup system

• System uses multicast for real-time content distribution and unicast for VoDcontent

BH Telecom’s Access network

• Primary access network is Copper wire – twisted pair – with ADSL 2+capacity

• Plan in progress for fiber optic cable – Fiber To The Curb solution – newareas of cities already connected with fiber optic

• Wireless access network – 802.11n solution within unlicenced bandwith –for rural areas and small towns – test period passed in heavily populatedarea in the capital city

• Ineternaly developed and deployed Automatic Configuration Server systemfor CPE equipment

• Bootcast servers and File Distribution servers for STBs

• The number of users during the first year of IPTV service in BH Telecom

• The number of purchased movies during the first year of IPTV service in BH Telecom
