In practice, this ideal is not quite achievable due to errors during the read process. Error correction coding (ECC) is one approach to overcoming the problem. Nevertheless, even a powerful ECC method will fail for some error conditions. A second approach for uncorrectable errors is concealment. For good concealment of video data, each erroneous or unknown pixel to be concealed should be surrounded by a sufficient number of good neighboring pixels.", "abstract$meta": { "confidence": "high", "note": "Backfilled from SMPTE canonical repository (smpte-canonical-audit/canonicalLibrary.*.json)", "originalValue": null, "source": "parsed", "updated": "2026-07-08T00:35:38.133Z", "version": "smpte-canonical-repo@v1" }, "authors": [ { "affiliation": "Ampex Corporation Redwood City, CA 94063", "bio": "Richard Brush has been senior engineer at Ampex Corp.
