Default ISTP Portals
When a user provides ISTP with an unrecognized URL or prefix, or intends to go to an unspecified home page, ISTP redirects the browser to the default portal. This approach can be monetized by the operators of these portals. Default behaviors for a system which a user, or customer, accesses often capture useful information about how the system is being used as well as provide a convenient way for people to interact with the system. Examples of these include default home pages set by browsers, search engines for mis-typed domain names in browser address bar, and default search engine behaviors for mis-spelled or mis-typed words. By enabling default portals, InterStream helps users to more easily find content on the network while offering the portal operators the opportunity to offer highly relevant content to those same users.
Monetizable Defaults for Operators, End-User Convenience
Obviously a default home page such as the one Firefox uses with Google (see article) offers a revenue opportunity for the company providing the service. Notably, Verisign attempted to offer a similar service for mis-typed DNS queries with more disastrous results. They were not able to capture the incremental revenue browser providers, such as Microsoft's Internet Explorer has been able to capture with their mis-typed DNS queries in the address bar. The Business Week article referenced (or linked) in the last sentence describes the Internet's infrastructure as "archaic". Perhaps, a better description would be that ICANN did not anticipate the natural tension which would occur between browser makers and the primary DNS operator, Verisign. Regardless of who can best monetize the default behaviors of a system in the DNS and HTML browser systems, ISTP offers a clean slate for capturing a customer's behavior and enabling a revenue opportunity for the provider of the media grid without the bureacracy and political restrictions of a body such as ICANN.
By enabling a useful default for the customer, or end-user, ISTP also provides a revenue opportunity to the operator of the default ISTP Portal. According to Georgia Tech, approximately 25% of all web sites are accessed directly from the address bar. In a recent Wall Street Journal article, they pointed out that roughly 15% of all web site access are due to mis-typed domain names and URLs. Most certainly, a significant percentage of web sites are accidently accessed or a more useful default could be offered to the customer. ISTP's design has been designed to support a useful default behavior which monetarily benefits the grid operator, not the browser provider. In addition, the InterStream asociation has considered the implications of this approach and acted accordingly to support it.
The ISTP default portal supports unique lexicographic conventions. Specifically, key phrases may be reserved in the portal name such that regular expressions may be used to match portal names for a given string after istp://. If the key phrase should refer to "adult content", then the client shall be redirected to an alternative "adult portal". The key phrases have been identified by InterStream's initial member working with the assocation and will cause the redirection of the ISTP client to this alternative portal. As outlined in the governance of ISTP portals, and any content or key words referring to such content will be expected to conform with the "adult portal requirements".
Media Grid providers leveraging their Default Portal
Individual ISTP plugin clients are designed to operate using a pre-defined media grid. As such, ISTP does not provide a selector for the media grid operator within its syntax. Instead, the media grid operator is determined by the client software downloaded into the browser or net-top. The media grid operator, therefore, determines which media grid to use for its streaming and default portal.
Two Types of Default Portals Currently Defined
There are currently two types of default portals currently defined for ISTP, "adult" and "mainstream". Users will be redirected to these default portals if they mistype, or intend to actively go to one of these portals by typing "istp://adult" or "istp://InterStream" into their browser address bar. For default behaviors and a more detailed defintion, please see the Default Portals and Unrecognized Domains section of ISTP & Ordinary URLs.
