A method of processing television content metadata in a communications system. The services summary region contains an ordered plurality of interactive summary tiles, each summary tile corresponding to a respective service and providing a character or graphical representation of at least one value for an aggregate key performance indicator characterizing the respective service as a whole. An extra feed forward transconductance stage extending from the input port of a first gain stage to the output port of a second gain stage of the amplifier is used in order to cancel one of two non-dominant poles in the transfer function of the amplifier with the additional zero introduced by the extra signal path. Moreover, using a uniform representation with constraints, the techniques make these disparate optimization principles highly cooperative. The WTRUs receive and process the downlink user data based on the downlink control information.
