MediaStack-ATSC/PSIP
   The FCC (Federal Communications Commission) has defined a roadmap to cease analog    transmissions in the not too distant future, driving demand for integrated digital TV receivers.

  Zentek MediaStack-ATSC features:
  -Base configuration certified to the ATSC specification
  -PSI/ATSC-PSIP libraries
  -DSMCC library
  -EIA-708B library
  -CableCARD library
  -Integrated font renderer optimized for the TV screen

MediaStack-OCAP (OpenCable Application Platform)
   MediaStack-OCAP is Zentek's fully compliant CableLabs OCAP commercial implementation that is    architected for easy portability to multiple platforms.
   MediaStack-OCAP was created independently of a specific virtual machine or hardware platform to    ensure portability and interoperability, and to provide customers with multiple vendor options.

 Zentek MediaStack-OCAP features:
  -Fully certified to OCAP specification
  -Designed for easy porting
  -Independent of Java VM or Hardware Platform

MediaStack-EIA 708B
   EIA-708B, the closed caption specification in North America is a key component required in all digital    TVs.

 Zentek MediaStack-708B features:
 -Pre-integrated photo engine (ClearView) to display characters clearly
 -All configurable font styles, sizes and foreground/background colors.
 -Concurrent display of captions in multiple languages

   MediaStack-708B is a modular, portable digital closed captioning solution that conforms to FCC    requirements as well as the ATSC mandatory standard. The integrated solution aims to enhance the    accessibility services that digital television broadcasters and network operators provide to the deaf    and hard-of-hearing population in the United States and Canada.

   MediaStack-708B also incorporates legacy 608 analog caption support and includes the ability to    display closed captioning in multiple languages simultaneously. Viewers can change all available    properties of the displayed text to suit their needs, such as font style, character size, foreground and    background color and edge effect.
   Zentek's commercial implementation of 708B includes an advanced, integrated font engine and    optimized screen display fonts, and its modular structure combines platform-dependent and    independent components for optimum portability.
