Abstract

In a video processing system, a method and system for a mobile receiver architecture for European (EU) Band cellular and 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 EU band cellular channels capable of carrying voice and data. The cellular channels may be WCDMA 2100 MHz, GSM 1800 or 900 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 channel, a second RFIC may process the GSM channels, and a broadcast RFIC may process the broadcast channel.
