Compression Overview

The goal of compression

lossless compression

When is lossy compression necessary?*

Goal for Improving Compression*

Compression improvement costs*

*Video compression quality is content and application dependent

Compression Overview

Intra-frame = I frame only

Inter-frame compression = Long GOP

long GOP can achieve higher compression ratios

long GOP compression performance is highly content and application dependent

Video CODECs balanced for applications

Image Qality

File Size

Complexity

How good will the

content look?

Will it hold up to further

processing:?

How much storage will I

require?

Will it fit in the pipe?

Will my hardware

encode/decode the

content fast

enough?

The Pie Gets Bigger

As processor speed improves

As storage gets cheaper

As high data rate physical links come into use

As GPU begin to be utilized

With Moore’s law

But Everyone Gets Hungrier

As resolution increases

As “temporal” resolution increases

As more downstream processing is expected

As production teams wish to be mobile

Utilizing WAN and wireless networks

Budgets are shaved

Many different people expect that THEY will get the extra piece from Mr.. Moore

What is AVC?

AVC stands for Advanced Video Coding

ITU-T was standardized it as “H.264”, and ISO standardized as “ISO/IEC 14496-10 MPEG-4 part10 AVC”

AVC is a core technology for all types of encoding applications

AVCHD - High profile AVC implementation supported by Panasonic and Sony

AVC-Intra - applications of AVC high profiles using Intra frame coding

AVC-Ultra are expanded AVC-Intra applications and other high profile applications

The goal of the JVT was to double the compression efficiency of then existing techniques

What does AVC give us Over MPEG 2?

Support for the new “formats”

60p, 444, 2K, 4K

Efficient compression of 10bit or 12bit quantization

Opportunities to trade complexity

For performance

For file size

& AVC – Intra Class 200

What’s New in the AVC toolbox?

Intra-Frame prediction

Variable block sizes, 2x2, 4x4 and 8x8

Integer Transform & Quantization

Improved Inter-frame prediction (long GOP) & motion estimation

Finer motion prediction accuracy

Powerful CAVLC and CABAC entropy encoding

Flexible image slicing optimizes multi-node processing

De-blocking Filters to hide errors

How About H.265??

More prediction tools

More block configurations

More entropy coding

More motion prediction

Heavier processor load

More later…

Intra frame Prediction

Some possible

prediction modes

Best approximation, repeat right

adjacent pixels Errors

Pixel Block Error Image

Variable Size Blocks

Varying block sizes are

chosen to provide best

fit to image data

structure and thus

generate optimal

coefficient data sets.

This creates more

efficient coding.

Motion Vectors

Improved INTER frame Compression

More complex (weighted) referencing More accurate motion vectors

¼ pixel & 1/8 pixel motion vector accuracy

& a variety of block sizes

Motion PREDICTION

What Is Entropy Coding?

More common data strings represented by fewer bits

Morse Code is Entropy Coding

Entropy coding requires knowledge of the statistical behavior of the data

n Context Adaptive Variable Length Coding (CAVLC) changes

the code table to suit the localized image content

~ 25%* improvement over non-adaptive coding (e.g.,

huffman coding)

n Context Adaptive Binary Arithmatic Coding (CABAC) looks

at the entire pictures probability distribution & can provide a

30% compression gain

~ 10%* improvement over CAVLC

*estimated average, real results are content dependent

Advanced Entropy Coding

No Change in Video Quality

Intra Frame CODEC Test

At Higher Bit Rates, AVC

encodes images so

accurately, reducing the bit

depth, reduces the

compression efficiency!

At Higher Data Rates Greater Bit Depth is More efficient!

CODEC Design Example AVC-Intra

A simple, yet powerful example of the

efficiency of AVC-Ultra.

16 channels of HD Long-G 25Mb/s

sent over one Cat-6 Ethernet cable

Small parsing server feeds 16 ToughPad

PCs via Gig-E router to decode 16 channels

of full res HD 4:2:2 10 bit content.

LongG enables the movement of high quality HD

(at “DV Bitrates”) over existing networks while

maintaining network speed.

AVC-LongG uses MXF OP-1b

OP-1a uses simple interleaving of the data;

okay for broadcast, but not easy to search

or manipulate e.g. Jog, Slo-Mo, scrub etc.

OP-1a also requires the entire file to arrive

before it can be played.

OP-1b uses “chunking” where the A/V data

is broken into 2 seconds “stand-alone”

chunks. Chunks can be played and processed

individually, audio is parsed in 2 sec chunks

also greatly easing head seeks / data buffering.

OP-1b can be played after just a few chunks

are cached.. Ideal for RT streaming!

What we should be asking ourselves

Does 4K even need to get into the home to be a factor?

Is 4K a “raster size” a new format or a chance to brake the rigidity of current

live broadcast formats?

Where is video technology growing?

How can we use 4K technology today?

What is stopping 4K from moving to live production?
