The VC-4 video streams can be dependent on any base layer video streams such as SMPTE ST 421 (SMPTE VC-1), ITU-T H.262 (MPEG-2), ISO\/IEC 14496-2 (MPEG-4 Part 2) or ITU-T H.264 (MPEG-4 AVC), etc. The storage format for VC-4 shall be extended from a particular file format which encapsulates a base layer video stream on which the VC-4 shall be depedent. The following file formats derived from ISO Base Media File format shall be extensible from this specification but are not limited to these: \u2022 MP4 file format (ISO\/IEC 14496-14) \u2022 AVC file format (ISO\/IEC 14496-15) \u2022 SMPTE VC-1 file format (SMPTE RP 2025) \u2014 The file format for storage of VC-4 content uses the existing capability of the ISO base media file format. In addition, the following new extensions to support new features of VC-4 codec are specified: \u2022 VC-4 Sample: a newly defined sample including a subset of enhancement layers or all enhancement layers of a picture. \u2022 VC-4 Extractor: a structure to enable efficient extraction of bitstream segment units from samples in other tracks instead of containing duplicate media data.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>SMPTE Recommended Practice &#8211; VC-4 Bitstream Storage in the ISO Base Media File Format<\/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>2011-11-09<\/td>\n<td>14<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":687051,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[637,646,2684],"product_tag":[],"class_list":{"0":"post-687039","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\/687039","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\/687051"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=687039"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=687039"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=687039"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
