    摘要: A router fabric for switching real time broadcast video signals in a media processing network includes a logic device configured to route multiple channels of packetized video signals to another network device, a crossbar switch configured to be coupled to a plurality of input/output components and to switch video data of the multiple channels between the logic device and the plurality of input/output components in response to a control instruction, and a controller configured to map routing addresses for each video signal relative to the system clock, and to send the control instruction with the mapping to the crossbar switch and the logic device.

    摘要: A focus assist circuit for a viewfinder, including a video amplifier configured to amplify a video signal, a video gain controller configured to adjust gain of the video amplifier to provide peaking headroom, and a peaking processor configured to adjust the amplified video signal. The focus assist circuitry may facilitate focusing a camera lens by proving peaking headroom for a peaking signal that is combined with an amplified signal. The peaking headroom limits the gain applied to a video signal in order to reduce distortions in the peaks. A user interface may include input controls configured to limit the gain of the of a video amplifier.

    摘要: An image sensor is provided. In one aspect, the image sensor includes a pixel coupled to an output line. The pixel includes a photodiode configured to generate electrical charges in response to light and a supply circuit configured to supply a voltage to the photodiode to keep a voltage of the photodiode at or above a threshold level in an integration time. In another aspect, the pixel includes a supply circuit configured to selectively supply voltage to the photodiode in a first charge holding capacity and a second charge holding capacity.

    摘要: The present aspects relate to techniques of timing synchronization of audio and video (AV) data in a network. In particular, the techniques for a AV master to distribute AV data encoded with one or more time markers to a plurality of processing nodes. The one or more time markers may be indexed to a precision time protocol (PTP) time stamp used as a time reference. In one technique, the nodes extract the time markers to determine an offset value that is applied to a PLL to synchronize AV data packets at a distribution node or a processing node. In another technique the distribution node or the processing node determines the worst case path, which corresponds to a system offset value. The distribution node then reports the system offset value to the AV master, which in turn adjusts the phase based on the report.
