Patent number: 6927805Abstract: A television receiver intended to decrease the number of expensive SAW filters to achieve low cost and a compact design. A trap circuit is interposed between a mixer and a SAW filter. During reception of a television signal, one of the trap frequencies at which the trap circuit responds is set to a video intermediate frequency on a television channel adjoining above an intermediate frequency band or a nearby frequency. The other trap frequency is set to a sound intermediate frequency on the adjoining television channel or a nearby frequency. During reception of an FM broadcast signal, the frequency of the FM broadcast signal is converted into a color subcarrier frequency on the intermediate frequency band or a nearby frequency.

Patent number: 6919929Abstract: A method and system for interfacing video and graphics data. Specifically, the present invention discloses a method and system for displaying video and graphics data of different formats and image frequencies onto the same display line. A master device that is continually streaming data of a first media type to a display at a certain image rate requests data from a source device one line at a time. The incoming line of data is sent to a FIFO buffer. A mixer associated with the master device then aligns the incoming data to the same format and image rate used for displaying the first media type. The incoming data is then displayed simultaneously on the same line with the data of the first media type. As viewed as an image, windows of video and/or graphics data are shown on a display.Type: GrantFiled: March 29, 2001Date of Patent: July 19, 2005Assignee: National Semiconductor CorporationInventors: Franco Iacobelli, Vikram Shrivastava
