Video coding

Video coding

Long history in standards development in:

ITU-T since mid-1980s (H.261): Video Coding Experts Group (VCEG) = Q6/16

ISO/IEC/JTC1 since early 1990s (MPEG-1): SC29/WG11 MPEG video coding ad hoc group

Joint work

1994  1998+: H.262/MPEG-2 Video

2001  2009: JVT: Joint Video Team

H.264 | ISO/IEC 14496-10 (MPEG4-AVC )

2010  … : JCT on video coding

Beyond H.264/AVC (new generation of video compression technology with substantially higher compression capability)

First outcomes expected 2012

Still image coding

Still image coding

Long history in standards development since mid-1980s:

ITU-T: Video Coding Experts Group (VCEG) = Q6/16 (started in CCITT SG VIII)

ISO/IEC/JTC1: SC29/WG1 (started in ISO TC97 SC2 WG8)

Joint work

1986: creation of JPEG, Joint (CCITT/ISO) Photographic Expert Group for cont. tone color image coding

1988: creation of JBIG Joint (CCITT/ISO) Bi-level Image Group for b/w image compression and coding

Many Common or Twin texts: T.8x & T.8xx series

JPEG, JPEG2000, JPEG-XR


Speech and audio coding

Speech and audio coding

Long history in standards development:

ITU-T since early 1970 (G.711): currently in Q10/16 (mainly), Q9/16, Q8/16

ISO/IEC/JTC1 since mid-1980s (MPEG-1 = ISO/IEC 11172): SC29/WG11 MPEG audio coding ad hoc group

Past work

ITU-T focus on speech codecs (Narrow band and wideband) for conversational applications

ISO/IEC/JTC1: focus on audio codecs (with greater audio bandwidths) for broadcast applications

Recent and ongoing work

ITU-T: audio bandwidth increase (superwideband, fullband), wider range of audio contents (such as mixed content, music, etc), enhancement of existing ITU-T codecs (more flexibility in bit rate/ audio bandwidths, adaptation to "modern" networks)

ISO/IEC JTC1: target lower delay codecs


Advanced multimedia system

Advanced Multimedia System

Q12/16 is working on Advanced Multimedia System (AMS), a new multimedia system for NGN and other packet-based networks

AMS will enable a union of physically separate devices, like a desk phone, mobile phone, or LCD panel on the wall

AMS will enable multiple applications to work together to deliver a rich communication experience

It is a project from the same multimedia communications experts group that created H.320, H.323, H.324, etc.

Work items: system architecture, terminal architecture, network facilities, signaling, etc.

Networked aspects of identification nid tag based id

Networked aspects of identification (NID) / tag-based ID

NID related work since 2006 under Q21/16 and Q22/16

Focused on tag-based ID triggered MM services and applications

Good foundation laid:

F.771: Service description and requirements for multimedia information access triggered by tag-based identification  

H.621: Architecture of a system for multimedia information access triggered by tag-based identification  

Ongoing work—two major methods accommodated to achieve maximum harmonization

ID schemes

ID resolution methods

Effective liaison work

ITU-T: JCA-NID,SG13 & SG17

ISO/IEC JTC1

JTC 1/SC 6 (OID resolution) & JTC1/SC31/WG6 (RFID)

11


Usn applications services

USN Applications & Services

Q25/16 is working on ubiquitous sensor network (USN) applications and services

Service description and requirements for USN middleware

An architectural framework for USN middleware services

Functional profiles of USN applications and services

A sensor information description language

Application interfaces among USN middleware entities

An identification scheme for USN elements including sensor nodes

Also covering Internet of Things aspects

F.744 with framework for USN middleware already approved, other Recommendations expected 2012

Msatc

MSATC*

In recognition of strong needs to better support video-centric multimedia services using DPI-based** technologies,Q22/16 started this work in early 2008.

DPI is employed to provide awareness of different MM service traffic to enable:

Better QoS

Management and regulation

Accurate billing

Labeling and suppression of harmful information(e.g. porn)

Services requirements and description work on F.MSATC is ongoing

Plans to start of approval process at next SG16 meeting

MSATC has potential applications in HN

Possible relation with other SGs

DPI work in SG13

* MSATC = Multimedia Service Awareness and Traffic Control** DPI = Deep Packet Inspection


Visual surveillance vs

Visual Surveillance (VS)

In a broad sense, visual surveillance can be viewed as a specific class of machine-to- machine applications

Joint Q21/16 and Q22/16 work since 2008

Telco-oriented visual surveillance is studied

Large scale system support

Convergence with other MM services e.g. IPTV

Completed deliverables

Framework for VS services in F.743

Architecture for VS services in H.626

Potential application in home networking
