Video signal processing system

A video signal processing system for processing a video data VIN and graphic data DμP, comprising:

• a) a horizontal filter that receives the video data VIN and converts the video data VIN into video pictures formatted with a different number of columns, and provides a horizontally filtered video signal indicative thereof, wherein said horizontal filter buffers individual pixels and/or lines in a first memory device;
• b) a second memory device that receives and stores the graphic data DμP and said horizontal filtered video signal and provides stored signals indicative thereof;
• c) a third memory device that is connected to said second memory, and stores data received from said second memory device;
• and
• d) a mixing and filtering unit that receives said stored graphic data and said stored horizontally filtered video data, vertically filters said stored horizontally filtered video data to convert the video data into video pictures with a different number of lines and provide a vertically filtered signal indicative thereof, and mixes said stored graphic data with said vertically filtered video signal to provide a video output signal VOUT.

A video signal processing system for processing a video data VIN and graphic data DμP, comprising:

• a filter unit, which receives the video data VIN and horizontally and vertically filters the video data VIN to convert the video data VIN into video pictures formated with a different number of columns and/or lines, and provides a filtered video signal indicative thereof, wherein said filter unit buffers individual pixels and/or lines in a first memory device;
• b) a second memory device that receives and stores the graphic data DμP and said filtered video signal and provides stored signals indicative thereof;
• c) a third memory device that is connected to said second memory, and stores data received from said second memory devices;
• and
• d) a mixing unit that receives and mixes said stored graphic data and said stored filtered video data to provide a video output signal VOUT, which represents a superposition of said stored graphic data and said stored filtered video data.
