TV-HTML - (Television Hypertext Markup Language) – (TV-HTML been folded into Cablevision's ETV App work and now is associated with OpenCable Platform (Tru2way). See OpenCable Platform, Tru2way, Ocap.) - TV-HTML is a HTML computer language (code) used for web pages viewed using a TV display. Some adaptations go into effect depending on the situation.  Other important factors include the resolution of the television screen, text size and the limits on the processing power of the set-top box (or related device). The aim of this type of HTML is/was to make the viewer unaware and unhindered by differences between the web they're used to seeing on the Internet, and the Internet they experience using TV-HTML. In this situation, network operators for the most part don't just want to bring the web to television viewers, but want to enhance the television viewing experience by incorporating the web and HTML, primarily with HTML 4.0 and above.
  There are various differences between regular and TV HTML. For instance a HTML "markup" is needed that will transfer a user from a web document to a specific TV channel: <gochannel tvref="7"> </a>. ("Mark up" is a part of the HTML code that consists of the characters that show up within the HTML brackets markers, <>, and controls how characters appear to people looking at the web site through a browser.)  The term "TV-HTML" was first used by Viewcall (which was later bought out by NetChannel, which was later bought out by AOL for incorporation into their former Web TV service AOLTV®.)
   In many cases standard web-authoring software such as Macromedia Dreamweaver, Adobe PageMill and Microsoft Frontpage can be used for producing TV-HTML enhanced content, but to produce interactive TV graphics one usually needs an image editor like Adobe Photoshop or Paint Shop Pro (as of 2003.) But that depends on how much and what type of enhancement are necessary. www.w3.org/TV
