Techniques and mechanisms for communicating packets of image information, the packets each having a respective format that is defined or otherwise indicated by a camera serial interface standard. In an embodiment, circuitry of a first physical layer (PHY) is operated to facilitate such communication via a lane of an interconnect that is coupled between the first PHY and a second PHY. The PHYs further communicate between each other a packet delimiter sequence between two such packets. In another embodiment, the plurality of packets and the packet delimiter sequence are communicated after a transition of one PHY from a relatively low power state, and prior to any subsequent transition of that PHY back to the relatively low power state. The camera serial interface standard specifies or otherwise indicates a protocol whereby a transition to such a low power state is performed between the respective communications of any two successive packets.

Device, apparatus and system to reduce current leakage during differential communications

In one example, a system for transmitting encrypted data includes a processor to select a virtual channel to be encrypted between an application processor and an image sensor during an initialization process. The processor can also transmit a virtual channel command corresponding to the selected virtual channel to the image sensor. The processor can also poll a register in the image sensor to verify the image sensor has stored an encryption key corresponding to the selected virtual channel and detect image data from the image sensor via the virtual channel, the image data encrypted with the encryption key.

Transmission of encrypted image data

In one example, a system for modifying transmission of image data includes a processor to detect a camera management command to transmit to an image sensor via a camera serial interface link. The processor can also transmit the camera management command to the image sensor via the camera serial interface link, and receive image data from the image sensor via the camera serial interface link.
