Signal Processing (SP) is one of the most extensive research areas at IBM. Our work is concentrated around the theory and application of filtering, coding, transmitting, estimating, detecting, analyzing, recognizing, synthesizing, recording, and reproducing signals by digital or analog devices or techniques. The term "signal" includes audio, video, speech, image, communication, geophysical, sonar, radar, medical, musical, and other signals.
IBM has made significant contributions in these areas from signal compression, analysis to secure delivery and transmission, and has participated in many of the major video and audio signal compression standardization activities such as JPEG, MPEG-2, MPEG-4, and MPEG-7. IBM also has several industry-leading products in this area such as ViaVoice, MPEG-2 encoder chips, Set-top box chips, TransNote and IBM Microdrive.
