Abstract: Various techniques for receiving broadcast at a mobile broadcast receiver are described. In an aspect, the broadcast receiver provides user notification and/or automatically launches an application based on user preferences. In another aspect, the broadcast receiver improves channel switching time by predicting future channel selection based on real-time monitoring of user inputs. In another aspect, the broadcast receiver supports drag-and-drop user interface. In another aspect, the broadcast receiver provides additional information associated with a selected broadcast stream. In another aspect, the broadcast receiver processes a broadcast stream and sends output data to an external device for further processing and/or display. In another aspect, the broadcast receiver simultaneously displays live content and stored content. In another aspect, the broadcast receiver simultaneously receives multiple broadcast streams for displayed on one or more display units. In another aspect, the broadcast receiver collects user statistics and sends the statistics to a network entity.

Abstract: Transceivers implemented with a combination of super-heterodyne and zero intermediate frequency (ZIF) topologies are disclosed. In an exemplary design, an apparatus includes a frequency conversion circuit and a local oscillator (LO) generator. The LO generator generates a first LO signal and a second LO signal. The frequency conversion circuit performs frequency conversion (i) between intermediate frequency (IF) and baseband, based on the first LO signal, for an IF signal and (ii) between radio frequency (RF) and baseband, based on the second LO signal, for an RF signal. The frequency conversion circuit may perform frequency downconversion (i) from IF to baseband for a super-heterodyne receiver and (ii) from RF to baseband for a ZIF receiver. Alternatively or additionally, the frequency conversion circuit may perform frequency upconversion (i) from baseband to IF for a super-heterodyne transmitter and (ii) from baseband to RF for a ZIF transmitter.
