Description

Interface Summary

Audio	Interface to provide audio stream sources to the MultiTaskerApplication architecture.
BackgroundImage	Interface for providing a series of background images.
Brand	A multitasker interface for a static "Branding" item like tv channel logos or a clock or whatnot.
Console	FUTURE e.g.
LocalOptionProvider	Implement this interface with each of your plugins (BackgroundImage, Audio, or TickerTape) that you also want to have their own options that work nicely with the option system
MultiTaskerApplication.ICallback	Interface for MultiTasker callbacks - uses animation chaining but easier to understand
PollingPopup	FUTURE Interface that will poll regularly and can do a popup on the screen.
TickerTape	Interface to provide instances of TickerTape.TickerTapeSegment (includes a default implementation) for the tickertape across the bottom of the screen in a MultiTaskerApplication.
TickerTape.TickerTapeSegment	The interface for the elements of a tickertape segment
TimedPopup	FUTURE Interface that will do a popup on the screen at a particular time (e.g.

Class Summary

AudioCaptionTicker	TickerTape that attempts to provide a reasonable segment for the currently playing Audio source.
AudioView	Handles URL redirects before using feed as a resource.
BackgroundImageCaptionTicker	TickerTape that attempts to provide a reasonable segment for the currently playing Audio source.
BackgroundView	View that holds the Background of a MultiTaskerApplication, driven by a BackgroundImage implementation.
BrandView
MultiTaskerApplication	Superclass of any applications that want to take advantage of the Multitasker architecture to automatically get configurable audio handling, ticker, background images, etc.
MultiTaskerApplicationFactory	Multitasker Factory - handle local files as streams and automatic reformatting of local images as streams.
MultiTaskerPreferences	Format of preferences definitions: optionKey, "Type[+],Label [options/for/strings]" Which is to say, the value for a key is a string where that starts with its Type (one of the LocalOptionProvider TYPE constants).
TickerTape.TickerTapeSegmentDefault	Default implementation of TickerTapeSegment if you just have 1, 2, or 3 strings you want returned as is.
TickerView	The view that holds the ticker and handles its refresh and animation.
URLProxyFactory	Deprecated. not needed...

Package com.blackledge.david.tivo.multitasker Description

TiVo Multitasker Application Architecture by David Blackledge. Enables a ton of features in your application by simply implementing MultitaskerApplication instead of BApplication. Once done, your application can have a user or application configured:

• TickerTape across the bottom of the screen that uses a variety of sources of information,
• Music playing in the background from a variety of sources,
• Images displayed in the background or used as a screenblanker with images from a variety of sources
• ... more in the future.

Developers can easily implement data source plugins for the various features to provide even more options for the user or application developer to draw on. Multiple data source plugins can be handled at once in round-robin fashion.
Your application also gains a powerful in-app configuration interface accessed via the "slow" button. Both the application and data source plugins can easily configure their own options with specific types and other features, seamlessly integrated into the preferences system. Options can be overridden by the application or it can simply provide specific default values.
The Multitasker Application Architecture also includes many commonly needed features:

• a Factory that can serve content from the local computer's drive
• The factory can serve images (local or remote) resized to fit within TiVo limitations and streamed (Getting around memory issues with ImageResource objects, allowing further multitasking by freeing your application from waiting to transfer the ImageResource definition, and improving display time by allowing the TiVo to handle the streaming while handling other operations simultaneously)
• The factory also supports short mapped proxy URLs to fit within TiVo limitations on URL length.
• Extraction of the actual TiVo's Address for use with e.g. my hmoclient package.
• Abstraction of the non-intuitive "Animation Chaining" concept into a simple Callback architecture.
• configuration-based handling of idle event.
• Utility functions to scale an image input stream.
• Utility functions to pre-handle redirected URLs (TiVo doesn't like them) or to extract multiple URLs from a single URL pointing to a list source (e.g. XML enclosures or shoutcast playlists)
• LIMIT constants for text rendering width/height.
• Standard option definitions for useful values like the Media Key and zip code.
