Abstract

A computing device and method for providing a user interface for summarizing and presenting information regarding dynamic provisioning and deployment of media processing resources, in a manner that is easy and intuitive and analogizes well to conventional physical media processing deployment. Users are not required to understand hypervisor configuration or virtual machine deployment, or switch through various layers and screens to find configuration information or controls, a process that may be particularly slow, complex, and difficult to learn, particularly for media and broadcast engineers unfamiliar with virtualization technologies. Instead, the present user interface improves efficiency of use of the computing environment for media processing, by providing deployment information in a format similar to physical processing deployment. Furthermore, because the user interface lends itself to intuitive monitoring and use, users may more accurately and efficiently deploy and undeploy processing resources, reducing overall system processing requirements, cost, and power consumption.

A system is provided for partial matching of settings across cameras. The system includes a camera setting controller that controls control elements of a target camera for capturing video content of a scene. Moreover, a transfer module detects a request to transfer settings from a reference camera to the target camera and a look determiner determines a look of a scene of the video content being captured by the at least one target camera. The transfer module retrieves the control elements of the reference camera and related image capture control settings that correspond to the obtained image capture control settings of the at least one target camera. The transfer module then transfers the image capture control settings of the control elements from the reference camera to the target camera, such that the settings are applied to the target camera to modify the capturing of video content of the scene.

Abstract

A media stream receiver is provided for scalable physical layer flow of packetized media streams. The media stream receiver replicates the processing block in time, rather than in hardware, through the use of a single shared memory and pointer alignment calculations, which combines multiple buffering stages as the single, shared memory buffer to offer redundancy and alignment, while acting as a receiver buffer to account for packet delay variations. By doing so the media stream receiver can perform a vertical interval switch between received media streams.

Abstract

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.

Abstract

A system and method is provided for performing lossless switching in a redundant multicast network. An exemplary method includes receiving a primary media stream and a redundant media stream over different forwarding network paths by network ports of a receiver communicatively coupled to an A/V device. Furthermore, the receiver outputs media data of the media streams to the A/V device to be presented thereon. In response to a control signal to switch the receiver to a new primary media stream, the method disconnected either the primary ort the redundant media streams from the respective network port of the receiver receiving that stream. Furthermore, the method includes controlling the disconnected network port to receive the new primary media stream and then outputting media data of the new primary media stream to the A/V device to be presented thereon.

Abstract

A computing device and method for providing a user interface for summarizing and presenting information regarding dynamic provisioning and deployment of media processing resources, in a manner that is easy and intuitive and analogizes well to conventional physical media processing deployment. Users are not required to understand hypervisor configuration or virtual machine deployment, or switch through various layers and screens to find configuration information or controls, a process that may be particularly slow, complex, and difficult to learn, particularly for media and broadcast engineers unfamiliar with virtualization technologies. Instead, the present user interface improves efficiency of use of the computing environment for media processing, by providing deployment information in a format similar to physical processing deployment. Furthermore, because the user interface lends itself to intuitive monitoring and use, users may more accurately and efficiently deploy and undeploy processing resources, reducing overall system processing requirements, cost, and power consumption.

Abstract

A system and method is provided for performing high dynamic range digital double sampling. More particularly, a CMOS image sensor is provided that includes a pixel array with each pixel sampling both dark and bright values for digital double sampling. After the sampled signals are digitized, a mean dark value is determined and each dark value is further fed to a lookup table that generates an output value taking into account whether the pixel has been saturated. In over exposed conditions, the lookup table will generate a negative value output to eliminate image artifacts. All three values are fed to adder logic circuit that subtracts the mean dark value and the lookup table output from the bright value. This resulting output is fed to a video viewer.

Abstract

A system and method that splices an initial 3D LUT for imaging format conversion into a plurality of smaller LUTs that can be stored in separate RAMs. During operation, the upper 5-bits serve as index values of each component of an incoming GBR pixel and are used to determine which of the smaller RAMs contain the correct index values for the pixel data. Specifically, a first index value can be derived from the incoming GBR pixel data and used to lookup all sub-cube vertices corresponding to the incoming pixel and the corresponding RAMs. After determining the correct RAMs, a predetermined algorithm for each given RAM is applied to find the normalized RAM look-up addresses and identify the correct data for the exemplary imaging format conversion process.

Abstract

An image processor is provided for correcting brightness of saturated pixels of a captured image. The image processor can include a pixel saturation determiner that whether one or more pixels in an image sensor have been saturated by comparing pixel brightness levels of the pixels to a predetermined saturation threshold. Moreover, the image processor includes an image enhancer that generates a corrected image without artifacts due to the saturated pixel(s) by replacing the pixel brightness of the saturated pixel(s) with a pixel correction value that is based on a pixel brightness of one or more unsaturated pixel in the image sensor.

Abstract

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.

Abstract

A system and method is provided for performing high dynamic range digital double sampling. More particularly, a CMOS image sensor is provided that includes a pixel array with each pixel sampling both dark and bright values for digital double sampling. After the sampled signals are digitized, a mean dark value is determined and each dark value is further fed to a lookup table that generates an output value taking into account whether the pixel has been saturated. In over exposed conditions, the lookup table will generate a negative value output to eliminate image artifacts. All three values are fed to adder logic circuit that subtracts the mean dark value and the lookup table output from the bright value. This resulting output is fed to a video viewer.

Abstract

A media stream receiver is provided for scalable physical layer flow of packetized media streams. The media stream receiver replicates the processing block in time, rather than in hardware, through the use of a single shared memory and pointer alignment calculations, which combines multiple buffering stages as the single, shared memory buffer to offer redundancy and alignment, while acting as a receiver buffer to account for packet delay variations. By doing so the media stream receiver can perform a vertical interval switch between received media streams.

Abstract

An IP router capable of isochronous switching of a packetized media stream. According to an example, the IP router parses the RTP header within an incoming IP datagram to extract the RTP time stamp, which provides a time value for a unique IP Flow. By inspecting the header, the IP router can switch the flow at the point in time that the RTP time stamp value changes, or matches a target value. In one aspect, the IP router looks for the change in the RTP time stamp value and performs the switch based on the detected change. In another aspect, the IP router performs the switch at a specified time stamp value that can be unique to a group of signals or based on a common “sync” value published to all the ports of the IP router.

Abstract

A computing device and method for providing a user interface for summarizing and presenting information regarding dynamic provisioning and deployment of media processing resources, in a manner that is easy and intuitive and analogizes well to conventional physical media processing deployment. Users are not required to understand hypervisor configuration or virtual machine deployment, or switch through various layers and screens to find configuration information or controls, a process that may be particularly slow, complex, and difficult to learn, particularly for media and broadcast engineers unfamiliar with virtualization technologies. Instead, the present user interface improves efficiency of use of the computing environment for media processing, by providing deployment information in a format similar to physical processing deployment. Furthermore, because the user interface lends itself to intuitive monitoring and use, users may more accurately and efficiently deploy and undeploy processing resources, reducing overall system processing requirements, cost, and power consumption.

An IP router capable of isochronous switching of a packetized media stream. According to an example, the IP router parses the RTP header within an incoming IP datagram to extract the RTP time stamp, which provides a time value for a unique IP Flow. By inspecting the header, the IP router can switch the flow at the point in time that the RTP time stamp value changes, or matches a target value. In one aspect, the IP router looks for the change in the RTP time stamp value and performs the switch based on the detected change. In another aspect, the IP router performs the switch at a specified time stamp value that can be unique to a group of signals or based on a common “sync” value published to all the ports of the IP router.

Abstract

A system and method is provided for performing high dynamic range digital double sampling. More particularly, a CMOS image sensor is provided that includes a pixel array with each pixel sampling both dark and bright values for digital double sampling. After the sampled signals are digitized, a mean dark value is determined and each dark value is further fed to a lookup table that generates an output value taking into account whether the pixel has been saturated. In over exposed conditions, the lookup table will generate a negative value output to eliminate image artifacts. All three values are fed to adder logic circuit that subtracts the mean dark value and the lookup table output from the bright value. This resulting output is fed to a video viewer.

Abstract

A camera using a CMOS image sensor based on a shared pixel array technology avails both high definition (HD) and ultra-high definition (UHD) resolution mode formats. Dynamic pixel management allows for both sequential and binned timing formats of pixel signals using switched capacitor noise reduction techniques. When UHD resolution mode is selected, noise can be reduced using both digital double sampling (DDS) or differential digital double sampling (dDDS), and when HD resolution mode is selected noise can be reduced using DDS. Additionally, both rolling shutter and global shutter modes can be selected when HD resolution mode is selected.

Abstract

A media stream receiver is provided for scalable physical layer flow of packetized media streams. The media stream receiver replicates the processing block in time, rather than in hardware, through the use of a single shared memory and pointer alignment calculations, which combines multiple buffering stages as the single, shared memory buffer to offer redundancy and alignment, while acting as a receiver buffer to account for packet delay variations. By doing so the media stream receiver can perform a vertical interval switch between received media streams.

Abstract

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.

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.

Abstract

A method and system for providing access to and control of parameters within a scenegraph includes redefining components or nodes' semantic within a scenegraph. The set of components or nodes (depending on the scenegraph structure) are required to enable access from the Application User Interface to selected scenegraph information. In one embodiment, a user interface is generated for controlling the scenegraph parameters. In addition, constraints can be implemented that allow or disallow access to certain scenegraph parameters and restrict their range of values.

Abstract

A pointer controlling apparatus, a control method, and a pointer controlling program are provided which can protect a button from erroneous operation without interrupting the operational flow or using excessive display area. The pointer controlling apparatus permits a pointer to move into a predetermined region after a predetermined period of time has elapsed from a point in time when the pointer comes into contact with a boundary line of the predetermined region. Accordingly, the predetermined area can be securely protected from a point in time at which the pointer comes into contact with the boundary line of the predetermined region for the predetermined amount of time. Furthermore, since the pointer is permitted to enter the predetermined region immediately after the predetermined time has elapsed, the predetermined region can be protected without interrupting the operational flow, and without using an excess of a display region.
