Next generation video compression
Requiring only half the bitrate of its predecessor, the new standard – HEVC or H.265 – will significantly reduce the need for bandwidth and expensive, limited spectrum. HEVC (H.265) will enable the launch of new video services and in particular ultra HD television (UHDTV).
State-of-the-art video compression techniques – HEVC/H.265 – can reduce the size of raw video by a factor of about 100 without any noticeable reduction in visual quality. With estimates indicating that compressed real-time video accounts for more than 50 percent of current network traffic, and this figure is set to rise to 90 percent within a few years, HEVC/H.265 will be a welcome relief for network operators.
New services, devices and changing viewing patterns are among the factors contributing to the growth in video traffic as people watch more and more traditional TV and video-streaming services on their mobile devices.
Ericsson has been heavily involved in the standardization of HEVC since it began in 2010, and this Ericsson Review article highlights some of the contributions that have led to the compression efficiency offered by HEVC.

This document provides an overview of MPEG-4, the open media standard for multimedia coding and delivery. MPEG-4 allows for interactive scenes composed of mixed media objects like video, audio, graphics and text. It provides efficient compression and representation of multimedia content across many delivery platforms. MPEG-4 aims to liberate multimedia delivery from proprietary technologies by offering an open standard supported by many industries and vendors.
Bridging the gap between web and television
Some ideas of how to bring the television closer to the web advancements, while preserving its own mission. Additionally, a set of MPEG tools covering aspects such as visual search, multimedia linking and multi-sensory experiences are also introduced.
Media processing in the cloud- what, where and how
The document discusses media processing in future communications networks. It asks what processing will be needed, where it will take place, and how it will be implemented. It argues that most media processing will remain in networks rather than terminals due to bandwidth, battery life, and interoperability considerations. Networks can provide services more efficiently by pooling resources and transcoding media in the cloud rather than relying on individual terminals. Both generic hardware platforms and dedicated DSPs will likely continue to be used for media processing, with DSPs preferred currently for voice and generic platforms gaining ground over time.
The MPEG Extensible Middleware API
The document discusses the MXM API, which provides a simplified interface for accessing MPEG technologies through wrappers and libraries. The MXM API exposes key functionality through various engine classes, standardizing access to features across MPEG-4, MPEG-7, MPEG-21 and other standards. This reduces 11,000+ pages of MPEG specifications down to a 37 page API specification with around 500 standardized methods. The API aims to simplify integration of MPEG technologies while maintaining control at the upper levels and offering sufficient access points.
Mpeg v-awareness event
The document discusses MPEG-V, a new standard for representing multi-sensorial and immersive experiences that combines both physical and informational worlds. It proposes using sensors to capture real-world stimuli and control virtual environments, with MPEG-V defining architectures and data formats to allow bidirectional exchange of information. Example use cases are presented where real-world motions or environmental data could influence and control virtual simulations.
MPEG Technologies and roadmap for Augmented Reality
This is a presentation I did during the 5th ATStandards meeting in Austin, 2012. It contains the MPEG Vision on AR as well as a very short overview of MPEG technologies related to AR

Data Security Using Steganography
While transferring a file from one point to another through Intranet and Internet we need more file secure concepts. Ordinary, file Encryption-Decryption Concepts, which are readily available in java examples are easily captured by middle way itself. So we need more security combination. This project helps to send a file from one place to another in a secured manner. Firstly the target file is encrypted and it is embedded into an audio or video or any media file. The resultant file will be protected by a password. This resultant media file is not changed in its original format and it can be run in the player, we can’t find any encrypted data inside it. This format will be sent through net. In the destination point it will be retrieved only by our software and giving the relevant password. So it is highly secured.

Steganography(Presentation)
The document provides an overview of steganography, which is the practice of hiding secret messages within other innocent messages or files. It discusses the differences between steganography and cryptography, various historical uses of steganography, and modern techniques such as hiding messages in digital images, audio, video and network traffic. The document also briefly outlines tools for steganography, challenges in steganalysis, and concludes with references for further information.
Data Security Using Audio Steganography
Steganography is the art and science of writing hidden messages in such a way that no
one, apart from the sender and intended recipient, suspects the existence of the message,
a form of security through obscurity. Steganography works by replacing bits of useless or
unused data in regular computer files (such as graphics, sound, text, HTML, or even
floppy disks ) with bits of different, invisible information. This hidden information can
be plain text, cipher text, or even images.
In a computer-based audio Steganography system, secret messages are embedded in
digital sound. The secret message is embedded by slightly altering the binary sequence of
a sound file. Existing audio Steganography software can embed messages in WAV, AU,
and even MP3 sound files. Embedding secret messages in digital sound is usually a more
difficult process than embedding messages in other media, such as digital images. These
methods range from rather simple algorithms that insert information in the form of signal
noise to more powerful methods that exploit sophisticated signal processing techniques
to hide information.
Steganography
This document provides an overview of steganography, including its definition, history, differences from cryptography, techniques used, and applications. Steganography involves concealing secret messages within ordinary files like images, audio, or video in order to hide the very existence of communication. Common techniques include least significant bit insertion and substitution. While steganography can benefit covert communication, it also enables malicious uses and is vulnerable to steganalysis attacks aimed at detecting hidden messages. The document outlines both advantages and limitations of steganography.
Video Steganography
Steganography is the art and science of sending covert messages such that the existence and nature of such a message is only known by the sender and intended recipient.
Steganography has been practised for thousands of years, but in the last two decades steganography has been introduced to digital media. Digital steganography techniques typically focus on hiding messages inside image and audio files; in comparison, the amount of research into other digital media formats (such as video) is substantially limited.
In this talk we will discuss the history of steganography and the categories of steganographic technique before briefly discussing image and audio steganography and how to build such tools. The main body of our talk will focus on how video files are coded and the steganographic techniques that can be used to hide messages inside video files.
The principles discussed in this talk will be illustrated with live demos.
Audio and video compression
This document discusses various audio compression techniques including:
1. Differential Pulse Code Modulation (DPCM) which encodes differences between samples to reduce bitrate.
2. Third-order predictive DPCM which uses predictions of past 3 samples to improve accuracy over DPCM.
3. Adaptive Differential PCM (ADPCM) which varies the number of bits used based on signal amplitude.
It then covers more advanced techniques like Linear Predictive Coding (LPC) which analyzes perceptual features of audio to further reduce bitrates.

Steganography - The art of hiding data
This document provides an overview of steganography, including:
1) Steganography is the art of hiding information in plain sight so that the very existence of a hidden message is concealed. It works by embedding messages within images, audio, or other files.
2) Modern uses include digital watermarking to identify ownership, hiding sensitive files, and illegitimate uses like corporate espionage, terrorism, and child pornography.
3) Techniques include least significant bit insertion to replace bits in files, injection to directly embed messages, and generating new files from scratch. Detection methods like steganalysis aim to discover hidden information.

Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

Introduction of Cybersecurity with OSS at Code Europe 2024
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
