Signal processing and standardization

Because in many instances signal processing is geared to communication, the attitude of the signal processing community regarding standardisation has always been very positive, leading to successful exploitation of its findings in the marketplace. Such standards as A-law/μ-law PCM, Group 3 facsimile, the Compact Disc, G.721, H.261, JPEG, MPEG-1, and MPEG-2 are all fine examples of how the signal processing technology available at a certain point in time was exploited to make successful signal processing standards. The fact that different standards were defined by different is just proof of the strategic value of a standard to favour or limit communications.
