Abstract (en)

[origin: WO2016097482A1] There are disclosed various methods, apparatuses and computer program products for media encapsulating and decapsulating. A container file according to a first format is received. The container file includes at least one meta data unit, and includes or refers to at least one media data unit, and the container file further includes or refers to a first checksum. Information of a first scope for the first checksum is obtained, wherein the first scope is a subset of the container file and/or the at least one media data unit, the first scope being for processing of the at least one media data unit. A first reproduced checksum is derived from the container file and/or the at least one media data unit on the basis of the first scope. The validity of the data within the first scope is determined on the basis of the first checksum and the first reproduced checksum; and subject to the data within the first scope being valid, the data within the first scope is processed.
