Dynamic service aggregation for efficient use of resources in interactive video delivery
To support future interactive information delivery services there is a need to balance individual interactivity with the desire to maximize the number of supported sessions. Currently, few techniques have demonstrated the ability to renegotiate and scale service parameters per session in progress as required to adapt to differing terminal equipment characteristics and network congestion. This paper addresses this problem through the definition of decomposable service groups that permit aggregation of interactivity, terminal characteristics, and levels of service scaling. The proposed approach applies the characteristics of end applications and data storage requirements to the design of a data scaling mechanism.
