Documentation Release Note

This guide aims primarily to explain the use of the SMIL 2.0 standard, and the RealNetworks extensions to SMIL 2.0, in RealONE Player. Please note the following about this guide:

• See Chapter 1 for summaries of new SMIL 2.0 features, as well as for information about additional changes to this manual from RealSystem Release 8.
• This guide documents a pre-release product. RealNetworks has attempted to make this guide as thorough and as accurate as possible, but you may find discrepancies between the instructions in this guide and RealONE Player performance. Known issues include the following:

• Secondary windows, which are described in the section "Secondary Media Windows", are currently plain windows that do not include the standard RealONE Player skin.
• Contrary to the information in "Replacing the Source Presentation", a source clip stops, rather than pauses, when another clip replaces it in its media window.
• Push wipe transitions, described in "Fade, Push, and Slide Transition Effects", are not yet functional.

• The following aspects of RealONE Player functionality have not yet been documented:

• How clip and presentation information displays in the RealONE Player user interface. The section "Managing Presentation Information" is a placeholder for this information.
• Support for media markers. The section "Using Media Markers" is a placeholder for this information.
• Support for wallclock timing. The section "Coordinating Clips to an External Clock" is a placeholder for this information.
• The min and max timing attributes. The section "Setting Minimum and Maximum Times" is a placeholder for this information.
• Time manipulations for animations. The section "Manipulating Animation Timing" is a placeholder for this information.
• The skip-content attribute.
• The <metadata> tag.
• The systemComponent and systemRequired attributes for <switch> tags.

• If you experience problems with the Javascript TOC and index, choose Plain HTML Version from the pull-down menu.
• This guide will grow over the next several months to include more information, authoring tips, and samples. Be sure to check for updates frequently.
• Thank you for previewing RealONE Player!
