4 Advanced Web Multimedia Web TV Applications Slide 4 of 26 Key Terms you must be able to use If you have mastered this topic, you should be able to use the following terms correctly in your assignments and exams: Web TV

5 Advanced Web Multimedia Web TV Applications Slide 5 of 26 Introduction MSN TV (formerly WebTV) is the name of both a thin client which uses a television for display (rather than a computer monitor), and the online service that supports it. The product and service were developed by WebTV Networks, Inc., a company purchased by Microsoft Corporation and absorbed into MSN (the Microsoft Network). It should be noted that the term web TV is also used concerning TV transmissions over the Internet, usually by streaming.

7 Advanced Web Multimedia Web TV Applications Slide 7 of 26 Introduction The WebTV product is an adapter that allows a television set to be connected to the internet, primarily for web browsing and e- mail. The setup includes a web browser, wired or wireless (i.e. bluetooth) keyboard and connection to the Internet (i.e. using modem, ADSL,). While WebTV does not allow as much functionality as a computer-based browser, it is a low-cost alternative to a traditional computer connection to the Internet.

8 Advanced Web Multimedia Web TV Applications Slide 8 of 26 Features The MSN TV 2 Internet & Media Player features include : –broadband or wireless home network compatibility, –online radio, –the ability to view digital photos on television, –or streaming Windows Media- compatible video and audio content.

9 Advanced Web Multimedia Web TV Applications Slide 9 of 26 Web TV Design Guide Primary Considerations Four primary components must be considered in broadcast design for the Web: The audience, screen size, color usage, and mouseless navigation

10 Advanced Web Multimedia Web TV Applications Slide 10 of 26 Audience: It is important for designers to realise the TV audience's expectation of being entertained. Broadcast designers must incorporate visual as well as textual content, including sound and animation. The TV audience is accustomed to one central focus point, and will be unfamiliar with "scrolling", "linking", "searching", and other functions that are second nature to the Internet's computer culture. TV audience will likely be viewing the screen from 5- 8 feet away, so font sizes will be rendered much differently than on a computer monitor (16-18 pt. fonts) Web TV Design Guide

11 Advanced Web Multimedia Web TV Applications Slide 11 of 26 Screen Size The design area is smaller for TV. The screen will accommodate pages of only 544 pixels wide and 376 pixels high, although the actual dimensions of the screen are somewhat larger. Color Dark backgrounds work better than light ones for TV, and both pure white and pure red should be avoided because they cause distortion. Horizontal rules of one pixel will flicker on a TV screen, so horizontal lines should be at least 2 pixels high. Web TV Design Guide

13 Advanced Web Multimedia Web TV Applications Slide 13 of 26 Navigation Navigation is accomplished using a keyboard, or possibly a remote control unit. Only about a quarter of what appears as a "screenful" of information on a computer will display initially on a television screen. Web TV Design Guide

15 Advanced Web Multimedia Web TV Applications Slide 15 of 26 Web TV Design Application Document Header information is supported, as are comments. The tag is recommended in order to pre- load the next page in a series. Document body...

16 Advanced Web Multimedia Web TV Applications Slide 16 of 26 Web TV Design Application Content Generally, content (text) should be arranged to reduce the need for scrolling. Television audiences appreciate this, especially in the absence of mouse navigation. Table (gradient angle)...

17 Advanced Web Multimedia Web TV Applications Slide 17 of 26 Web TV Design Application Frames Later versions of WebTV support frames - to an extent. However, the "Target" attribute for the tag is not supported, nor are the "Scrolling" or "Noresize" attributes of the tag. The tag is supported and encouraged, but MSIEs floating frames is not. Forms Forms are supported and can use either scripts or "mailto:" as the form handler. However, navigational limitations, and the possible lack of a keyboard, make forms a less than user-friendly web site feature

18 Advanced Web Multimedia Web TV Applications Slide 18 of 26 Web TV Design Application Images Multimedia Sound and animation contribute a great deal to the creation of a more "television-like" experience for the user. The latest version of WebTV supports a wide spectrum of sound and animation, including: wav, aiff, au, MOD, MIDI and GSM, RealAudio 3.0, and MacroMedias Flash 1.0. (In coming months, Flash 2.0 will be supported by both WebTV Classic and WebTV Plus.).

19 Advanced Web Multimedia Web TV Applications Slide 19 of 26 Conclusion The television interface to the Web offers much potential, especially to providers of goods and services. As WebTV's CrossOver Links(TM) become more common, integrating television programming with web site content will greatly enhance the media experience for the viewing audience.
