ABSTRACT

Digital cinema encompasses every aspect of the movie making process,

from production and post-production to distribution and projection. A digitally

produced or digitally converted movie can be distributed to theatres via

satellite, physical media, or fiber optic networks.

The digitized movie is stored by a computer/server which "serves" it to a

digital projector for each screening of the movie. Projectors based on DLP

Cinema® technology are currently installed in over 1,195 theaters in 30

countries worldwide - and remain the first and only commercially available

digital cinema projectors.

Digital technology has already taken over much of the home

entertainment market. It seems strange, then, that the vast majority of

theatrical motion pictures are shot and distributed on celluloid film,just like

they were more than a century ago. Of course, the technology has improved

over the years, but it's still based on the same basic principles.

INTRODUCTION

The reason is simple: Up until recently, nothing could come close to theimage quality of projected film. Digital cinema is simply a new approach to makingand showing movies. The basic idea is to use bits and bytes (strings of 1s and 0s) torecord, transmit and replay images, rather than using chemicals on film.

The main advantage of digital technology (such as a HYPERLINK"http://entertainment.howstuffworks.com/cd.htm" CD ) is that it can store,transmit and retrieve a huge amount of information exactly as it was originallyrecorded.

Digital cinema affects three major areas of movie-making:

Production - how the movie is actually made Distribution - how the movie gets from the production company to movie theatersProjection - how the theatre presents the movie.

INTRODUCTION

• Today piracy is hurting everyone– Films, Music, Software, Pharmaceuticals, Print, Merchandising– any area involving

• The Indian Film Industry with USD 1.75 Billion in revenues loses up to 50% of its revenues to pirates i.e. roughly USD 875 million to piracy.

• Cinema distribution and exhibition business in India carried out almost entirely on celluloid format which leaves it vulnerable to piracy.

• Advancement in duplication technology has made piracy easy, cost effective, speedy and difficult to prevent.

• The only present safeguard against piracy is to physically guard the prints and stringent legal enforcement. Both measures, due to logistical reasons, are difficult to implement.

• However, piracy is essentially a technology problem which has to be combated with technology.

Indian Cinema – The Present Scenario

We Cannot Fight the Pirates

• Piracy the world over has become an industry, technology is allowing it to flourish.

• Film and Music Industry are hit the hardest. Not much headway has been made in filmed entertainment to combat piracy, despite huge efforts.

• The music industry is fighting by policing as well as by market strategies of reducing the rates, in films this is not possible since the cost of tickets and prints is more or less fixed.

• Today the only way to beat pirates is to kill their business model

How do we achieve this?

• The only answer is Digital Cinema• The only answer is Digital Cinema

• Digital Cinema means the transmission and delivery of films to theatres electronically where the image is stored in a computer server and beamed onto the theatre screens.

• It uses Digital Media (fiber optics, satellite transmission, hard disks) instead of analogue media (Prints ).

• Digital Cinema uses digital projectors instead of analogue projectors.

• Hence Digital Cinema by eliminating all physical formats checks Piracy at its roots.

Digital Cinema – Final Frontier of Filmed Entertainment

Digital Cinema – The Only Solution

• Digital Cinema curbs piracy in three ways

– Digital transmission of films to theatres eliminates “en route” content leakage

– Elimination of print cost provides an opportunity for a much wider release, thus taking the content to the viewers before the pirates can do so

– Encrypting the content to protect the copyrights of the producers and distributors

• Wide and economical release of movies through digital cinema is the only option to block the pirates. Widespread release will divert the funds from the pirates back into the cinema value chain

UFO-Anti Piracy at every stage

The following anti piracy features of UFO Moviez ensures that the • The following anti piracy features of UFO Moviez ensures that the content is protected end to end.

– Firstly, conversion into D5 tapes take place at a dedicated media centre with bio-metric access control.

– Secondly, a 192 bit AES encryption system encrypts the film, frame by frame.

– Thirdly, license to play the film is given via Digital Video Broadband Link onto the smart cards installed in the UFO servers.

– Fourthly, transfer of content from server to projector is secured by means of a HDCP cable.

– Lastly, a unique identification code ensures that the source of the movies copied from the UFO theater screen can be easily identified.

Difference between ANALOGUE & DIGITAL VIDEOWhat is analogue video?

Analogue video transmits or stores video data in a continuous wave of redgreen and blue (RGB). each colour’s wave to display changing images at the receiver’send. Since this format involves an unbroken transmission of wave data.. analoguevideo data represents reality better.

Celluloid film onto which pictures and sound are recorded (partially digital)Highly mechanical projectors, many moving partsTried and tested method used for decades

Difference between ANALOGUE & DIGITAL VIDEOWhat is digital video?

Digital video is nothing more than a series of images ,all stored in digital format(ones and zero) that is displayed in quick succession on a screen(such as a computer monitor).

A digital video recorder ,for example, takes analogue signals (light waves )and records them into a digital representation of the analogue dat. So almost all digital video is nothing but a computer’s understanding of analogue video. There are exceptions such as in the case of , say ,games, where there is no analogue data to begin with ,and all the data is created and displayed digitally.

Difference between ANALOGUE & DIGITAL VIDEO

where digital video has the definite upper hand.

Analog’s Disadvantages:

•Distribution - expensive, slow• Film Preparation - labor intensive, error-prone• Inflexible

• Changing venues requires physically moving print• Large lead-time for ordering prints, limited selection of low-risk films

Advantages of digital:

•Picture and sound represented digitally• Stored temporarily at theater on computer hard drive or streamed directly from distributor• Screened with high-res digital projector• Relatively very efficient•

DLP (DIGITAL LIGHT PROCESSING)

In the digital cinema system the DLP can perform main role .now we discussabout the DLP(digital light processing). And how it can be used with in the digitalcinema.

1.A digital projector based on DLP Cinema® technology transfers the digitized imagefile onto three separate optical semiconductors known as DMD chips. Each of thesechips is dedicated to one primary color – red, green, or blue. A DLP Cinema chipcontains a rectangular array of over one million microscopic mirrors.

2. Light from the projector's lamp is reflected off the mirrors and is combined indifferent proportions of red, green and blue, as controlled by the image file, tocreate an array of different colored pixels that make up the projected image. Thinkof the DMD’s as the colored cards held up by an audience in a sports arena tocreate a giant image. Each person holds up a single colored card, yet whencombined, these thousands of cards create a picture. If the card colors are changed,the picture changes too.

3. Each micromirror tilts either toward or away from the light source thousands oftimes per second to reflect the movie onto the screen. These images aresequentially projected onto the screen, recreating the movie in front of you withperfect clarity and a range of more than 35 trillion colors.

The business of digital cinema

In July 2005, after years of evaluating and testing different technologies, thestudio members of Digital Cinema Initiatives,(DCI), a joint venture of Disney, Fox,MGM, Paramount, Sony Pictures Entertainment, Universal and Warner BrothersStudios, published and released to the industry voluntary technical specificationsfor Digital Cinema. These specifications Provide a guideline for technologyproviders ensuring the system’s components are Interoperable and provide a highlevel of security for the content.

In the Fall of 2005, Access Integrated Technologies, Inc. (“AccessIT”) aftersuccessfully negotiating with major Hollywood Studios, contracted Christie DigitalSystems for the supply of an integrated DCI-compliant Digital Cinemasystem. AccessIT created their wholly owned subsidiary, Christie/AIX, an entityresponsible for executing an innovative business plan and administrator for thefirst practical Digital Cinema rollout in the world. Christie/AIX serves as theintermediary between content owners (major studios and independentdistributors)

TECHNOLOGY CREATED PIRACY

TECHNOLOGY WILL KILL PIRACY

Digital cinema the transmission and delivery of films to theaters electronicallywhere the images stored in a computer severs and beamed on to the theaterscreens. It uses digital media like fiber optics, satellite transmission, hard disksinstead of analogue media like prints. Digital cinema uses digital projectors insteadof analogue projectors.

Hence digital cinema eliminating all physical formats checks piracy at its rootsthat will help to the cinema producers and distributors and also it will reduce thecost of film making.So the digital cinema is one of the best transmission for gettingmore profits to the developer also users.
