Abstract:

An iTV user interface includes a navigable menu area through which a user can select from among a variety of services and a content display area in which formatted data associated with a selected menu service are displayed to the user. The formatted data is displayed in a rotating or ticker fashion having both a passive mode, in which the formatted data is displayed in a sequence independent of any selection operations by a television viewer, and active mode, in which the formatted data is displayed in a sequence that depends on selection operations by the television viewer. Advertisements and/or promotions may be interspersed among the content items. The navigable menu area and the content display area may be displayed to the viewer at the same time as television programming is displayed on the television.

Abstract:

A method and system for constructing risk parity portfolios wherein the overall portfolio risk is diversified by allocating the risk equally or substantially equally across various portfolio components. The system receives a selection of investments assets, covariance matrix of the assets, and constraints including bounds on the weights of the investment assets. The system optimizes a mathematical formulation that is constrained by the bounds on the weights of the investment assets to generate a solution that is used for constructing a risk parity portfolio having optimal asset allocations that result in a balanced risk contribution.
