JPEG2000 AllianceWho• a consortium of technology leaders

Goal• JPEG2000 development

into a leading compression standard• JPEG2000 widespread acceptance and deployment

How

• educate and create awareness about the benefits of JPEG2000

• support of the compression standardfor the benefit of the media and video industries

• promote interoperabilitybetween standards and system devices

• promote the development of tools by members and industry peers


About JPEG2000

License free Open standard Lossy and lossless

compression Error Resilient Precise and

adjustable bit rate control

Scalable Low latency

Constant quality through multiple generations

Supports 4K resolution (and greater)

Up to 32-bits per component

Symmetric encode and decode


Mathematically Lossless Compression

• It enables a reduction in storage requirement of, on average, 1:2 while still being able to recover the exact original image information.

• Extremely important feature in fields such as digital archiving, cinema acquisition and medical imaging.

• Unique advantage in comparison to JPEG, MPEG2, MPEG4


Scalability

• JPEG2000 is able to extract multiple versions out of a single compressed file

• This scalability provides– Easy proxy generation– Region of Interest– Bandwidth optimization

and adaptive transmission


Low Latency

• Intra-frame allows every frame to be encoded independently allowing latency of less than 1 frame

• In comparison, inter-frame encoding formats (e.g. MPEG2, MPEG4) need to work with Groups of Pictures (GOP) that require a longer processing time

• Low latency is a critical consideration in many applications


Constant Quality Through Multiple Generations• Successive encoding-decoding passes are

usually required throughout the Broadcast and Digital Cinema post-production processing chain

• JPEG2000 provides a constant image quality throughout the production process

VSF JPEG2000 Activity Group

Mission

• Create a recommendation for standardization of real time transport of JPEG2000 for Contribution over IP Networks

• Real time service encapsulating JPEG2000 compressed video, audio, time codes & closed captioning in a program stream

• Encapsulation into MPEG2TS and the IP/RTP structure for final transport

• Utilize a single RTP stream for video/ audio/ancillary

• CBR & VBR streams supported

• Streams up to 1800Mbps supported

Two solutions/efforts:• MPEG2TS/SMPTE2022

initially thought to be faster to market and with backwards compatibility with legacy MPEG2TS equipment

– Recommendation development is ongoing, must work with JPEG and MPEG to complete a standard

• MXF Wrapping over RTP with RTP/Payload Header & FEC

– VSF work for native uncompressed video should be usable for this effort

– EBU will pursue this activity

What Can I do with JPEG2000 in

Broadcast?

• High-quality compression of contribution video feed

• Studio-to-affiliate video transfer• Intra-studio video • High quality storage and playback of

multiple feeds• Little degradation over many multiple

compression cycles


End-to-end video

• Input contribution HD-SDI format (SMPTE 292)• JPEG2000 in contribution, mastering, mezzanine• Usage models in venue, studio and network• Combine video, audio and metadata for transport

– Video compressed with JPEG2000 – Audio compressed or not, variety of options– Metadata in various forms and formats

What to do with JPEG2000? Networked Video


Multi-viewer Systems: Resolution Scalability

• Features– Encoded sources available on visualization network– Sources are combined in a multi-viewer

• Benefits– Freely combine JPEG 2000 streams– Leverage JPEG 2000 resolution scalability


Desktop Monitoring:Low Latency, High Quality& Resolution Scalability

• Features– Encoded sources available on visualization network– All frames are viewable/editable (intra-frame coding)– A regular PC can decode the video sub-resolutions

• Benefits– Video is being shown at high quality– Resolution can be matched to view size/compute power– Video is being shown at low latency Monitor network sources from desktop !

JPEG2000 as a Preservation Master

• JPEG2000 is fast becoming the defacto standard for preservation quality content archiving

• Media and entertainment companies have been slow to adopt but the opposite is true for archivists

• Limited “interoperability” between typical broadcast devices and “large file sizes” are considered barriersTrue preservation presents different challenges than traditional file based operations in media organizations

Storage Efficiencies

• Archive Package average approx 180Mbps with all target essence formats (preservation, interoperable and proxy)

• Formats can be added/removed depending on specific goals

• A single LTO4 data tape provides:– 800GB of storage capacity– 10 hours of source content Archive Package storage– €30 street price!

• Many goals are simultaneously accomplished:– JPEG2000 for long term content preservation (LOSSLESS!)– MPEG2/DV for broadcast device interoperability– MPEG4/WM9/FLV/etc for proxy browsing/web/mobile
