Included are formulas for converting SMPTE ST 12-1 time address values and MPEG-2 PCR time base values to local wall clock time, and formulas for converting SMPTE ST 12-1 time address values directly to\/from MPEG-2 PCR time base values. Local wall clock time conversion formulas are useful for converting between different frame rates of SMPTE ST 12-1 time code; e.g., a 24-fps SMPTE time code running at 23.976 fps could be converted to true time and then to a 29.97 drop frame SMPTE time code value. Finally, a discussion of how ST 12-1 time code may be carried within the coded video structures of both MPEG-2 and MPEG-4 AVC is provided.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>SMPTE Engineering Guideline &#8211; Conversion of Time Values between SMPTE ST 12-1 Time Code, MPEG-2 PCR Time Base and Absolute Time<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/smpte\/\"><b>SMPTE<\/b><\/a><\/td>\n<td>2016-08-10<\/td>\n<td>20<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":686775,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[637,646,2684],"product_tag":[],"class_list":{"0":"post-686765","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-33-160-01","7":"product_cat-33-170","8":"product_cat-smpte","10":"first","11":"instock","12":"sold-individually","13":"shipping-taxable","14":"purchasable","15":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/686765","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/686775"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=686765"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=686765"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=686765"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
