US Patent:

7639887, Dec 29, 2009

Filed:

Dec 14, 2004

Appl. No.:

11/011737

Inventors:

Eric J. Roberts - Chandler AZ, US

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06K 9/36
H04N 1/405
G06K 9/46

US Classification:

382252, 358296

Abstract:

In an embodiment, a method includes receiving values of a first pixel and a second pixel of an image at an input processor element of an image signal processor and distributing fractional parts of a number of values from surrounding pixels to the first pixel and the second pixel non-serially using first and second accelerator units, respectively, of the image signal processor. The method further includes assigning output values to the first pixel and the second pixel based on the values of the first pixel and the second pixel and the fractional parts of the number of values from the surrounding pixels using an output processor element of the image signal processor and outputting the output values to an output device that has a color range that is less than a color range of the image using the output processor element.

Abstract:

Mechanisms for managing output of an HDMI source are provided. In accordance with some implementations of the disclosed subject matter, a method for controlling output of an HDMI source is provided, the method comprising: establishing a connection between the HDMI source and an HDMI sink at a first address of a consumer electronic control bus of the HDMI sink; sending a request for an identity of the active source connected to the HDMI sink; monitoring signals on the consumer electronic control bus; receiving a message over the consumer electronic control bus identifying a second address on the consumer electronic control bus different from the first address as an address of an active source; setting a status of the HDMI source as inactive in response to receiving the message; and inhibiting output of video from the HDMI source to the HDMI sink in response to the status being set as inactive.

H04N 21/485

Abstract:

Mechanisms for controlling an audio level of an HDMI audio system are provided, the mechanisms comprising: causing audio data to be presented by an HDMI audio system at a current system volume level; receiving a requested volume level from a second screen device; and controlling a system volume level by: (a) determining the current system volume level; (b) determining a change in volume based on a difference between the requested volume level and the current system volume level; (c) determining a direction in which to cause the system volume level to change; (d) sending a volume control message to the system using a consumer electronic control bus connected to the system indicating whether to increase or decrease the system volume level based on the determined direction of system volume change; and (e) repeating (a)-(d) until the current system volume level reaches a predetermined value.
