Some video services require video clips to be delivered to users via server out-dial or "push". This is particularly relevant for specific user requested content and event-triggered and scheduled deliveries.

Some examples include:

	User request via SMS
	User request from a WAP page
	User request from a Web page
	Scheduler triggered requests at pre-determine intervals

Applications that would benefit from this approach include:

	Printed advertisements on newspapers, magazines and outdoor advertisements - interested readers could send a SMS to request a video clip of the product.
	Video Greeting & Dedication applications - users could preview and select video greeting cards from a WAP or Web site and dedicate them to their friends and relatives.
	Organizations such as fan clubs, special interest groups, etc. may schedule to send video updates regularly to their members.

	NANO 3G VIDEO PUSH SERVER
	Nano VPS (Video Push Server) is a generic 3G video call out-dial system. It is a software product that runs on standard Intel server. VPS enables service providers to offer video services that "push" video clips to designated recipients upon receiving a trigger from an external application. VPS is designed to support multiple services on a single server. Each service may have it owns pre-recorded video preambles and end messages. Standard HTTP API allows external application servers such as SMS gateways or schedulers to trigger video out-dial.
