Embodiment

[0493] Example: Streaming Interface

[0494] Some accessories can support IP streaming between themselves and the controller. As in the IP camera embodiment above, real-time media streaming is an option, but other types of data streaming may also be supported. For example, TCP or UDP streaming may be supported. In some embodiments, the attachment may be required to stream all data in encrypted form. For example, for TCP streams, TLS-PSK (ChaCha20 / Poly1305) can be used, while for UDP streams, DTLS-PSK (ChaCha20 / Poly1305) can be used. In some embodiments, the implementation of IP streaming may be similar to the IP camera service embodiment described above. Alternative implementations are also possible. Embodiments will now be described.

[0495] Figure 33 An exemplary service definition is shown for an IP streaming service 3301 according to one embodiment of the invention. exist Figure 34 The properties are defined as Streaming Capability Property 3401 , Str...

Abstract

A uniform protocol can facilitate secure, authenticated communication between a controller device and an accessory device that is controlled by the controller. An accessory and a controller can establish a pairing, the existence of which can be verified at a later time and used to create a secure communication session. The accessory can provide an accessory definition record that defines the accessory as a collection of services, each service having one or more characteristics. Within a secure communication session, the controller can interrogate the characteristics to determine accessory state and / or modify the characteristics to instruct the accessory to change its state.
