Editing Picture Transfer Protocol (section)

==Version 1.11==
'''PTP v1.11 (ISO 15740:2013)''' is a minor revision to '''PTP v1.1'''  '''(ISO 15740:2008).'''  Both the 2008 and 2013 versions of PTP are fully backward-compatible with PTP v1.0 '''(ISO 15740:2005)''', and offer optional performance, compatibility, and feature enhancements including:
* A mechanism for handling streaming content
* A mechanism to support multiple vendor extension sets
* Support for objects larger than the 4GiB size limit set by PTP v1.0, by requiring 64 bits (8 bytes) for object size
* Support for retrieval of ''ObjectHandles'' in enumerated chunks. This may reduce long response times for some devices that possess large numbers of objects
* Support for arbitrary resizing prior to image transmission (responder scaling). In PTP v1.0, image sizes might be requested in full-resolution or thumbnail size only
* Support for arrays of datasets. This can be used to reduce the number of required transactions necessary for device characterization from being a function of the number of objects on the device down to one
* A fast file characterization operation that exploits dataset arrays to request, in a single transaction, only the minimum data required to characterize a typical filesystem
* A new standard ''ObjectFormatCode'' to support the [[Digital Negative (file format)|Digital Negative (DNG)]] file format
