An Overview of Multimedia Content Protection in Consumer Electronics Devices
An overview of multimedia content protection in consumer electronics devices Ahmet M. Eskicioglu* and Edward J. Delp‡ *Thomson Consumer Electronics Corporate Research 101 W. 103rd Street Indianapolis, Indiana 46290-1102 USA ‡ Video and Image Processing Laboratory (VIPER) School of Electrical and Computer Engineering Purdue University West Lafayette, Indiana 47907-1285 USA ABSTRACT A digital home network is a cluster of digital audio/visual (A/V) devices including set-top boxes, TVs, VCRs, DVD players, and general-purpose computing devices such as personal computers. The network may receive copyrighted digital multimedia content from a number of sources. This content may be broadcast via satellite or terrestrial systems, transmitted by cable operators, or made available as prepackaged media (e.g., a digital tape or a digital video disc). Before releasing their content for distribution, the content owners may require protection by specifying access conditions. Once the content is delivered to the consumer, it moves across home the network until it reaches its destination where it is stored or displayed. A copy protection system is needed to prevent unauthorized access to bit streams in transmission from one A/V device to another or while it is in storage on magnetic or optical media. Recently, two fundamental groups of technologies, encryption and watermarking, have been identified for protecting copyrighted digital multimedia content. This paper is an overview of the work done for protecting content owners’ investment in intellectual property. Keywords: multimedia, copy protection, cryptography, watermarking, consumer electronics, digital television, digital video disc, digital video cassette, home networks. 1. INTRODUCTION In the entertainment world, original multimedia content (e.g., text, audio, video and still images) is made available for consumers through a variety of channels. -

DAT330 – Principles of Digital Audio Cogswell Polytechnical College Spring 2009
DAT330 – Principles of Digital Audio Cogswell Polytechnical College Spring 2009 Week 6 – Class Notes Optical Disc Media: CD and DVD Optical Disc Media Design of Optical Media Most optical storage systems store data across the surface of a flat disc. This allows random access of data, as well as ease of manufacturing replication. Because the data is written and read via optical means, there is no physical contact between the media and the pickup. This ensures long media and pickup life and minimizes damage through head crashes or other failures. In addition, a protective layer can be used to protect the data from damages or contamination. Also, multiple data layers can be places within one substrate. Nonetheless, stored data must undergo both modulation and error correction. Data can be stored either along a spiral or concentric tracks. Most optical disc pickups shine a laser on the medium, and the reflected light is detected by a sensor and decoded to recover the carried data. The medium must have two states so that the change between them varies with the reflected light. Data can be represented as a phase change, polarization change, or change in the intensity of reflected light. The resulting variations picked up from the media can be converted into a varying electrical signal for data recovery. Laser beams, having a short wavelength, allow for high information data density and a high SNR needed for a high bit rate. Optical media must be supported by a sophisticated servo system to provide positioning, tracking, focusing of the pickup, and accurate rotation. -

The document filed by the CSC requested a public hearing/inquiry on the monopolistic business practices of General Instrument Corporation and the distribution and sale to consumers by the General Instrument division of Forstmann Little Corporation of a defective descrambling product which is used by consumers and cable operators to unscramble programming delivered over satellite. As a research and development firm which has spent the past three years developing a universal scrambling system designed to run multiple encryption and decryption processes through one single decoder, we submit that General Instrument has deceived the pUblic, the governments of the united States and Canada, television programmers, hollywood producers, satellite and consumer electronic retailers, and the manufacturers of Integrated Receiver Descramblers in the sales and upgrade programs associated with its videocipher II scrambling system, (exhibit A).

Medress, General Instrument Corporation Elizabeth H. Prodromou, M.I.T., Rapporteur __ ·~~~__~_~~____ This session of the MIT Communications Forum brought together three speakers for a discussion of issues related to direct broadcast satellite technology and services. The idea of direct-to-home satellite television has been around for many years, but it exists in America primarily for those who do not connect to a cable system. However, the possiblity of high power satellites, flat receiver dishes as small as a serving tray, 256 ahannels on one bird and HDTV have created new opportunities for communications that could exceed the potential of cable. Most plans involve the first widespread use of digital video as a consumer item, a fundamental change to television. The speakers in this panel will address the broadcasting plans and technical innovations for new approaches to DBS that are slated to go on- the-air as early as next year. Prof. Andrew Lippman of the MIT Medi Laboratory introduced the speakers, with some summary opening remarks on direct broadcast satellite (DBS) technology. He noted that, while the Communications Forum periodically has held discussions on HDTV, today's discussion was somewhat different than those in the past insofar as the discussion will point to the convergence between many programming and technological developments. -

Hux, 940 F.2d 314 (8th Cir. 1991) In United States v. Hux I the Eighth Circuit concluded that the Wire- tap Law2 did not proscribe the modification of satellite descramblers to 3 receive encrypted programming. On two occasions, an undercover agent requested that the defendant, Austin Jerry Hux, modify a satellite descrambler module* to receive pre- mium pay television channels without the user paying the provider of the program.' Hux performed both of these modifications and received $400 for each.6 A Federal Grand Jury returned a four-count indictment against Hux: two counts of manufacturing an electronic device for the purpose of sur- reptitiously intercepting electronic communications under the Wiretap 1. -
