A method of determining adjustment of an image pipeline setting comprises determining, by a controller, one or more settings for image data processing in the image pipeline; associating the one or more settings with a tag; transmitting the one or more settings to the image pipeline, wherein the tag is transmitted in association with the one or more settings; transmitting, from the image pipeline to the controller, feedback regarding image data processed with the one or more settings, wherein the tag is transmitted in association with the feedback; and determining, based on the received feedback and the one or more settings associated with the tag, an adjustment of the image pipeline setting.

Methods and apparatus for securely streaming multimedia packets, such as RTP packets, are disclosed, in which the payloads of the packets are shuffled. This reordering is performed using a shuffling function that depends on sequence numbers associated with each of the packets, a pre-determined group size N, and a pre-determined initialization value; in some embodiments this shuffling function comprises a cryptographic hashing function or other one-way function. A receiving device may reverse the shuffling, using a similar shuffling function, if the pre-determined group size N and the pre-determined initialization value are known.
