  • Patent number: 11165998
    Abstract: 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.

  • Patent number: 8204217
    Abstract: 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.

  • Publication number: 20110035768
    Abstract: The present invention relates to a server and a client for providing parental control of media content and methods thereof. In order to achieve a more flexible service deployment of the parental control, the parental control is implemented in the service consumption period according to the present invention. The operator can then offer content services which do not require a specific service order. The server sends a message to the client indicating that a parental control verification code is required in response to a request of a content during the consumption phase. A parental control verification code such as a PIN code is then inserted in a field in an authentication field originally intended for a password for authenticating the user. Thereby, parental control can be achieved even if a specific service order is not performed.
