Abstract

In a video processing system, a method and system for a mobile receiver architecture for US Band cellular and VHF/UHF broadcasting are provided. Received channels may be processed in at least one radio frequency front end (RFFE) in a mobile terminal and may comprise at least one of a VHF/UHF broadcast channel and World band cellular channels capable of carrying voice and data. The cellular channels may be WCDMA 1900 or 850 MHz and GSM 1900 or 850 MHz. A single cellular/broadcast radio frequency integrated circuit (RFIC) may be utilized for processing the received channels. In another embodiment, a cellular band RFIC may process the EU band cellular channels and a broadcast RFIC may process the broadcast channel. Moreover, a first RFIC may process the WCDMA channels, a second RFIC may process the GSM channels, and a broadcast RFIC may process the broadcast channel.
