About this product: This book explains the fundamentals of digital rights management systems including identifying, tracking, authorizing and restricting access to digital media. You will learn how DRM systems help to protect and enforce copyrights, patents, trademarks, and other forms of intellectual property. Digital assets can take various forms including audio, data and digital video. You will discover how it is possible to provide simple access to authorized users (paying customers) and how to restrict access to unauthorized users. Digital media content must be uniquely identified. The common identification codes that may be assigned to digital media include ISBN (books), ISSN (magazines), DOI (multimedia) and watermarks. You will learn that DRM systems may include a DRM controller, digital asset manager and DRM packager that allow DRM systems to receive requests for digital assets, to find and retrieve the assets and to packages (encode) to protect the assets during delivery and use. Digital assets can be monitored and tracked using a variety of information including their distribution addresses (IP address) and through unique identifying characteristics of the digital media such as the use of digital watermarks. Protocols and standards can be used to define rights elements of digital media and services. Some of the DRM languages covered in this book include XrML, SDMI, XCML, ORDL, RDF, REL and others. You will discover how authentication works without the need to transfer secret keys through communication systems. The basic encryption processes are described along with introduction on some of the ways to use and implement encryption. The common DRM threats including hacking and ripping methods are explained along with ways to reduce the risk of decoding and copying of digital media by unauthorized people. Some of the most important topics featured are: . Fundamentals of DRM Systems . Copyright, Patents, Trademarks and Intellectual Property . Audio, Data and Video Digital Assets . Media Identification Options . Digital Content Distribution . Managing, Tracking and Restricting Digital assets . Tracking and Digital Watermarks . Protocols and Standards . Authentication and Encryption . Common Hacking Methods
About this product: Digital rights management (DRM) is a set of business models and technologies that allows media companies to protect their intellectual property -- and profit in the online world. Cowritten by DRM pioneer William Rosenblatt, this lucid primer outlines the state of DRM today for media executives and IT decision-makers, covering business models (such as subscriptions), core technologies (watermarking, encryption, authentication), standards (such as XrML), vendors, and more.
About this product: Describes the frequency bands used for broadcasting below 30 MHz: Low frequency (LF) band - from 148,5 kHz to 283,5 kHz, in ITU Region 1 [1]* only; Medium frequency (MF) band - from 526,5 kHz to 1 606,5 kHz, in ITU Regions 1 [1] and 3 [1] and from 525 kHz to 1 705 kHz in ITU Region 2 [1]; High frequency (HF) bands - a set of individual broadcasting bands in the frequency range 2,3 MHz to 27 MHz, generally available on a Worldwide basis. These bands offer unique propagation capabilities that permit the achievement of: Large coverage areas, whose size and location may be dependent upon the time of day, season of the year or period in the (approximately) 11 year sunspot cycle; Portable and mobile reception with relatively little impairment caused by the environment surrounding the receiver.
About this product: This survey is focussed on consumer attitudes towards usage restrictions that are imposed by DRM. Survey respondents comprised 405 online users in the United Kingdom spanning the age band 15 to 65 years, each of whom said they had a collection of digital music. Key Topics: Most annoying usage restriction; Increase in digital expenditure if DRM removed; Propensity to share digital vs. CD albums; Changes needed to just buy digital music; Music album expenditure - all formats; Reasons for not adopting digital music. Please Note: This report is sold as GSL
About this product: The Drawing Requirements Manual contains instructions for the preparation of engineering drawings and models based on ASME Y14.100, ASME Y14.5M-1994, ASME Y14.41-2003, and many other standards and specifications for commercial applications, along with information on MIL-DTL-31000 for Department of Defense (DoD) and other government applications. Simply put the Drawing Requirements Manual explains the information contained in these standards and specifications, provides information on to how apply the applicable rules/techniques, clarifies the material in the applicable standards, and finally one of its most valuable features - adds additional rules and requirements where needed.
The new 11th Edition of the Drawing Requirements Manual has been revised so that the information with in it aligns with the current revisions of the many standards it covers, and aligns with current and forthcoming trends in the industry. This is all highlighted by the new Section 26 on 3D Solid Modeling and Using Digital Data and Annotated Models as Design Deliverables. The new Section 26 of the DRM 11th Edition includes a an inclusive interpretation of ASME Y14.41-2003, containing additional material not found or addressed in ASME Y14.41-2003, techniques for 3D application not listed or inadequately addressed in the standard, and the realities of the workplace demanding additional guidance beyond the material in ASME Y14.41-2003 or anywhere else.
About this product: Provides visual examples of acceptability requirements, defects and conditions found in through-hole solder joints on electronic assemblies.
