摘要： A method for focussing a film scanner provides for selecting a plurality of partial regions of the picture to be scanned for the purpose of focus monitoring. During the focussing of one of the selected partial regions, the focussing of the other partial regions is simultaneously monitored. The monitoring is effected for example by simultaneous representation of the partial regions on a monitor screen, and/or by evaluation of the frequency and amplitude conditions of the partial regions. An optimum focal point is set if all the selected partial regions are simultaneously set sharply.

摘要： A method is described for extracting selected time information from a stream of serialized AES digital audio data. A first transition indicative of a first preamble of said stream of serialized AES digital audio data is detected and, upon detection of the transition, a time count initiated. A second transition indicative of a subsequent preamble of said serialized AES digital audio data is subsequently detected and the time count halted. The time separating the first and second transitions is then determined. The separation time, which preferably is determined in the form of a fast clock pulse count, is then transferred to a decoding logic circuit for use in decoding the stream of serialized AES digital audio data.

摘要： A method includes designating at least three storage partitions on at least two logical drives, placing a first storage partition on a first of the logical drives adjacent to a second storage partition on a second of the logical drives separate from the first logical drives, and creating a third partition among both the first and second of the logical drives. The first, second and third partitions are balanced for storage access symmetry such that the drives bear equal storage placement.

摘要： 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.

摘要： A broadcast camera is provided that includes a camera housing having connectable camera housing portions to define a front, middle and rear sections of a camera body. An electronic component is provided in the front section of the camera housing and a power transformer is mounted in the rear section of the camera housing. A duct housing is mounted within the camera housing to form a cooling duct that extends through the camera housing, with a front duct housing that is positioned adjacent to the electronic component and that separates the electronic component from the cooling duct. Moreover, heat sinks extend within the cooling duct in one of the upper, middle and lower front duct sections and are mounted to be in thermal communication with the at least one electronic component. A fan is mounted within the cooling duct to draw air into the cooling duct.

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.

摘要： 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.

摘要： A production system having a first production path, a second production path, and a control system that causes the first production path to generate a show in a first aspect ratio and the second production path to generate the same show in a second aspect ratio. Moreover, the product system can product a show from live material and from archived material. This aspect operates by producing a first show including multiple stories, segmenting the first show, and storing the show segments in an archive. Then, the system produces a second show using live portions as well as show segments retrieved from the archive. The product system can include a media manager that interacts with a server that may be integrated with the production system. The media manager automatically assigns channels/ports of the server when accessing material stored in the server.
