What does adoption of PTP-IP make possible? Further, what merits does it have for users?
PTP was used to be connected with USB, PTP-IP can now become to utilize TCP/IP as a PTP transport, and as a result, PTP applications can now be implemented / realized in network and wireless environments.
Merits include, for example, wireless connection of digital cameras and personal computers, and a direct printing function through wireless connection of digital camera and printers.

Is this a standard for image transfer between personal computers and digital cameras?
Yes.
It uses PTP, which is an image transfer protocol that has been widely used from the past with digital cameras. PTP-IP was standardized as a conversion protocol for connecting this PTP to TCP/IP network environments.

Is PTP-IP compatible with the PTP/IP used by some digital camera manufacturers?
As CIPA is not concerned with PTP/IP, please ask the digital camera manufacturers.

Is PTP-IP compatible with MTP (Media Transfer Protocol)?
As MTP is a standard put forward by Microsoft, please ask directly regarding details.

Will the PTP/IP used by manufacturers until now be unified into this PTP-IP in the near future?
The CIPA hope to be unified.

Does PTP-IP utilize any technology that was not already in existence?
Yes. PTP-IP is based on the technology of the PTP and TCP/IP already in existence.It allows multiple simultaneous connections among digital imaging devices, which had not been possible with USB.

Does PTP-IP define transmission using IEEE802.11a/b/g and via Ethernet?
No. PTP-IP does not define transmissions in network environments lower than TCP/IP.

Does PTP-IP define transmission in ad-hoc mode and infrastructure mode?
No. PTP-IP does not define transmissions in network environments lower than TCP/IP.

Does PTP-IP define transmission passing through routers?
No. PTP-IP does not define transmissions in network environments lower than TCP/IP.

Does the CIPA guarantee interoperability with devices of the different manufacturers?
No. The CIPA is not an institution that guaranties interoperability.

Is there any institution that will certify interoperability with devices of the different manufacturers?
No.

Where can I obtain technical information or ask technical questions?
For questions about the outline of the standard, see the White paper available here.
If you have any further questions, ask here.
