Core Technology and Standards
InterStream, as an Industry Association, defines the standards necessary to implement the ISTP and ISML technologies required to enable a high quality hyperlinked video transmission system, by ISPs, content providers, network equipment vendors, and others who wish to deliver a high quality streaming experience over existing network infrastructure.
The Media Grid represents a new approach to hosting information on the Internet. Under the current paradigm, a business or individual as a customer may choose web hosting services from a number of providers. With the nature of the HTTP protocol, and best-effort nature of the Internet, a customer chooses a provider who may use a single server with its own IP address. More sophisticated Web Hosting services may use technologies such as Dynamic DNS to create resilient higher performance multi-server hosting systems. Similarly, CDN operators use proprietary mechanisms to distribute content closer "to the edge" of the network improving resiliency, performance and reducing bandwidth costs. Single server locations cannot possilbly offer the required service levels for a video on demand services. Therefore, InterStream has created a "Media Grid" to span the backend Internet and offer higher performance streaming services.
InterStream's MediaGrid approach and architecture uses existing network infrastructure with a minimal investment and changeover required by Internet Service Providers (ISPs) or others to adopt its system. Two primary technologies comprise the system:
The MediaGrid provides three key advantages over existing video Internet standards and infrastructure:
