Chapter 2. iTV Scenarios > Trading Scenarios

2.12. Trading Scenarios

Viewers are given the option to access, through a dedicated trading service, their accounts with an online brokerage firm via an interactive TV application. The application enables trading stocks, checking account balances, and obtaining real-time stock quotes. This type of application can be transmitted with either a live TV program or an advertisement. An interactive stock ticker may also be part of the application.

It is assumed that a channel will carry services provided by a single brokerage firm. The viewer is authenticated before access is granted. The static pages are retrieved from the local receiver's cache, and the dynamic pages are retrieved from the return channel. All financial transactions are secure. Confirmation of transactions arrives through the return channel.
