Abstract: A broadcast receiver 200 includes a receiver/decoder 210. The receiver 200 receives a broadcast channel selected by a user from a plurality of broadcast channels available in a broadcast network The receiver makes signals broadcast via the selected channel available to the user. User input means 230 enable the user to specify a user interest profile 400 based on at least one category of preference 410, 420, 430. An installer 220 install of all channels available in the broadcast network only those channels that meets the user interest profile 400.

Abstract: A broadcast receiver 300 includes a tuner/decoder 310 for tuning into a broadcast digital transport streams. The tuner/decoder 310 can also extract at least one service from the transport stream. A service includes one or more selectively receivable service components. An example of a service component type is a program (hereinafter “Xlets”) that is executable by the processor 320 of the broadcast receiver. The processor 320 is programmed to present to a user a guide with Xlets available for receipt. The processor 320 also enables the user to select at least one of the presented Xlets. In response to a user selection, the processor 320 causes the tuner/decoder 310 to tune into the transport stream that carries the selected Xlet, and to extract the selected Xlet.
