Digital Sampling to Create a Hybrid Media Feed

Re-present Sub-Project

INTRODUCTION TO PNN

• Create an Application that uses principles
• f sampling to produce an Aesthetic

Response

• Create a Framework for Art Production

OBJECTIVE

FOUNDATION

'What is an artist, basically? He's a collector who wants to establish a collection of his own, making the pictures himself that he likes by other

• people. That's how I begin, and then it turns into something else.'

and… "To copy others is necessary, but to copy oneself is pathetic.”

• Pablo Picasso

Music

• Classical Composers - versions of the

same symphony

• Musique Concrete - music from “found

sound”

– Stockhausen, Cage, Reich

• HipHop

– Sugar Hill Gang - WuTang Clan

Visual Art

• Sculpture of David

– Donatello, Verrocchio, Michelangelo, Bernini

• Cubism

– Braque, Picasso

• Dada and Surrealism

– Ernst, Duchamp

• Contemporary - appropriation

– Levine, Kruger, Prince

• In the visual arts, one of the fundamental changes is the

transition to the digital sampling of imagery. Now the sources of appropriation can be replicated and redistributed without

• degradation. The distribution of imagery is not limited to “one off”

art objects.

Transition to Digital

PREVIOUS WORK

• Art Tools - functional
• Artworks - non-functional

Art Tools: Max/MSP+Jitter

• Cycling74
• When combined

with Jitter, becomes a sampling visual art production tool

• Can create

standalone artworks

Art Tools: Auto-Illustrator

• Signwave UK
• Automatic,

generative graphic tools

• Interface and tool

design idiosyncratic to the programmer.

Artworks: Web Stalker

• Artist - I/O/D
• 1997
• Considered the

first stand- alone Internet art application

• Alternative

Browser

Artworks: Shredder

• Artist - Mark

Napier

• 1998
• Alternative

browser

• Reformats

existing web pages

• Reliant on

traditional web browser

Artworks: Netomat

• Artist - Maciej

Wisniewski

• 1999
• Alternative

Browser

• True standalone

application

• Netomatic (XML)

files

Artworks: combinFormation

• Artist - Andruid Kerne
• 2000
• Recombinant

Information Space

• Dynamism

Artwork: EARTH

• Artist - John Klima
• 2001
• Visualization of

Internet derived information

• Macro to micro

point of view

• Gives form to data

Concepts

• Simulation
• Sampling
• Dynamism
• Cognition
• Digital Rights

Working Process

Working Process

Simulation

• Oliver Grau - Virtual Reality: From Illusion to

Immersion

– Roman frescoes 60 B.C

• Lev Manovich - Language of New Media

– History of the Screen

• Classical
• Dynamic
• Real-time
• Virtual

Simulation - PNN

• Focus

– Environment stripped of superfluous stimuli – Minimize noise

• Situationist International

– Détournment – Dérive

Sampling

• Well established history in visual arts

– Braque, Picasso, Eisenstein

• Semiotics

– Sign composed of Signifier and Signified – Signifier not essentially related to Signified – Meaning is a construct of our culture – Re-contextualized imagery creates new meaning

Sampling - PNN

• PNN will work with these ideas to create an

environment that extracts cultural content and provides the viewer the opportunity to manipulate meaning effects.

Dynamism

• Content that takes advantage of “instant”

connectivity of the Internet

• Combined with navigable space, it becomes

a media type unique to new media

Cognition

• Object-Oriented Models of Cognitive

Processing

– Dynamic process versus procedural

• Story Elaboration

– Many people “complete” stories independent of facts relayed by the news broadcast itself – Meaning created by newsbyte

Digital Rights

• Originated in England

– Means of censorship granted to publishing industry, printing press owners – Rewritten in 1710 as “anti-censorship” law so authors could claim their own work – Rewritten to “encourage public learning”

• U.S. - An Act for the Encouragement of

Learning”

– Expedite the integration of innovation into the public domain – Never intended to control free speech nor contributions to daily dialog of culture

Digital Rights - PNN

• Place the responsibility for DRM in the

hands of the individual as opposed to the programmer or corporations

API

• Java
• JOGL - Java for OpenGL
• QuickTime for Java

Hardware

• Development - Apple

G5 Dual 2Ghz - OSX

• Server - Apple G4

Dual 800 - OSX

Hardware

• Video Capture -

Sony DSR-20 Digital Video Recorder

Hardware

• Boca Labs

TextGrabber GP500 Closed Caption Decoder

Scope

• Project divided into three major

components

– Client Application – Server Application – Website

• M.S. Thesis implements Client application,

PhD work integrates Client/Server/ Distribution - case study of immersive aesthetic experience

Client Application

• Initialization
• Main Window
• Mouse Navigation
• Episode Information and Transcripts
• Episode Video
• Video Search
• Settings and Preferences
• SCREENSHOTS

Server Application

• Video
• Transcripts
• Models

Re-present Sub-Project

Server Application - Schematic

Server Application - Transcripts

Re-present

• A research project that functions as an

independent hypertext artwork, yet exercises ideas and implements methods initiated in the development of PNN.

• Hyper-textual visualization that searches

television news broadcast transcripts, and “Re-presents” the data in a way that affords the viewer the opportunity to come to a “new” understanding.

Indexer Captionator Re-present Client CC Decoder PNN Server Re-present Server

Indexer Captionator

Captionator - Transcripts

• Decode transcripts and save to server.

– Integrate time-code to match text with video – Serial connection to CC Decoder and DV Recorder

Indexer - Reverse Index

• Create searchable index of terms to reside
• n server
• Using Jakarta Lucene

Re-present Client

• Fullscreen Java application
• Uses Jakarta XML-RPC for remote

procedure execution

PNN Server Re-present Server Re-present Client

• Interfaces with Lucene
• Uses Jakarta XML-RPC
• CLI daemon

Re-present Server

Re-present Client PNN Server Re-present Server

Re-present Client Functionality

• Displays Broadcasts, Date and Time

Re-present Client Functionality

• displays temporal location of search term

results

Re-present Client Functionality

• Displays broadcast title and number
• Height of broadcast is related to term

frequency within the transcript

Re-present Client Functionality

• Height of broadcast node is related to term

position within the document

– shorter to front, longer towards rear

Re-present Client Functionality

• Mousing over the broadcast node displays

the phrases containing the search term.

Re-present Demo

EVALUATION

• Art is subjective - individual response

dependent on experience of observer

• Function is objective

– Performance – Bugs

FUTURE WORK

• Integrate WordNet to enable word

interpretation, and expansion of “meanings”

• Implement “stretch text” on phrases
• Implement word expansion, link following
• Improve “visualization” perhaps with

animated node responses

• Develop community - setup open source
• repository. Members could develop their
• wn visualizations of PNN data.
• Develop tactile response

CONCLUSION

• Satisfies Client application goals
• Successfully presents the opportunity for

the manipulation of meaning in the context

• f an aesthetic experience
• Provides framework for art production
