Abstract: An information embedded method is used with a broadcast source and a broadcast signal receiver using a unidirectional transmission medium. The information embedded method includes steps of: storing information-push files in the broadcast signal receiver during a first time period; the broadcast source delivering broadcast signals to the broadcast signal receiver through the unidirectional transmission medium during a second time period posterior to the first time period; and the broadcast signal receiver selecting one of the information-push files according to a predetermined rule and combining the broadcast signals and information content of the selected information-push file to form an information embedded program. An information embedded system includes the broadcast source and the broadcast signal receiver.

Abstract: A signal analysis system is provided that includes master DSP circuitry, slave DSP circuitry, a LVDS bus, wherein the LVDS bus couples the master DSP circuitry to the slave DSP circuitry, and a USB interface, wherein the USB interface is coupled to the master DSP circuit.
