DEUTSCHE TV-PLATTFORM: HYBRID TV - BETTER TV HBBTV AND MUCH, MUCH MORE Deutsche TV Platform (DTVP) was founded more than 25 years ago to introduce and develop digital media tech- nologies based on open standards. Consequently, DTVP was also involved in the introduction of HbbTV. When the HbbTV initiative started at the end of 2008, three of the four participating companies were members of the DTVP: IRT, Philips, SES Astra. Since then, HbbTV has played an important role in the work of DTVP. For example, DTVP did achieve the activation of HbbTV by default on TV sets in Germany; currently, HbbTV 2.0 is the subject of a ded- icated DTVP task force within the Working Group Smart Media. HbbTV is a perfect blueprint for the way DTVP works by promoting the exchange of information and opinions between market participants, stakeholders and social groups, coordinating their various interests. In addition, DTVP informs the public about technological develop- ments and the introduction of new standards. In order to HYBRID BROADCAST BROADBAND TV (OR “HbbTV”) IS A GLOBAL INITIATIVE AIMED achieve these goals, the German TV Platform sets up ded- AT HARMONIZING THE BROADCAST AND BROADBAND DELIVERY OF ENTERTAIN- icated Working Groups (currently: WG Mobile Media, WG Smart Media, WG Ultra HD).

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. -
