The SEG-2550 is a compact, cost effective video switcher with all the advantages of latesttechnology from Son~ The SEG-2550 has been developed to meet the demandingrequirements of both production switching and complex post production in the studio oredit suite.The SEG-2550 is designed specifically to integrate the *E-FileTM effects memory control andcommunicating interfaces with a computer and an editor: The E-File facility can memorizeall of the special effects data generated by manual controls to be reproduced duringproduction, providing sophisticated programming possibilities.The SEG-2550 complements the versatile video system package using U-matics, cameras,and the BVE-9OQ edit controller for sophisticated program production..E-File is a trade mark of Sony Corporation1. WIDE RANGE SWITCHING CAPABILITY8 video inputs and 4 busEight looping video inputs plus black/white or colorbackgrounds are equipped for three effects modes, MIX,WIPE, and an EXTERNAL KEY with NB bus.wipe is the effect of a horizontal stripe pattern in pairs.Echo WipePairing WipePRESET/PROGRAM busThe Preset (PST)/Program (PGM) bus for the MIXING(dissolve) or TAKE mode, and the preset bus displays theexact result of the next lever movement.Background color and color matteA background color or black/white generator is provided inaddition to 8 video inputs.Desired color background can be created.t .External keyThe external key mode is provided with a key bus, andaccepts signals from color or B/W camera sources.Versatile wipe patterns and controlNine kinds of patterns can be selected directly by pushingthe respective wipe pattern key on the control panel.A total 137 patterns can be selected by inputting therespective wipe pattern numbers. Mosaic patterns suchas 8 x 8 are included. Wipe pattern modifiers, such as thepositioner, the border wipe, softness border edge, andecho/pairing wipe further expand the applications of wipeeffects when used in combination with the wipe patterns.Echo wipe is an effect with a graded mix.

2. DOWNSTREAM KEY FACILITY SEG-2550 is in REM mode and its status can beKeysourceThe downstream keyer (DSK) of the SEG-255O accepts akey source from a B/W camera or from a SMC- TOG Sonymicro-computer.Shadow and edge adjustmentThe shadow of the key signal can be created with narrowor wide adjustment. The edge adjustment of the insertsignal from a B/W cameramakes the key signal clear.Independent color generation for the DSKThe color of the insert source can be selected from thecolor matte generation, B/W or, external source (ex.painted characters with colors generated by the SMC- 7OG.)Preset and ProgramPreset/Program cut in/out mode is provided to preview theresult of the DownstreamNormal/Invertmodekey effects.Normal mode or invert mode can be selected accordingto the white or black key base.3. POST PRODUCTION INTERFACEInterface with a new Edit Controller, theBVE-900The SEG-2550 can be controlled directly from the Sony'snew editing controller, the BVE-900 with a BKE-915(RS-232C interface board). Sony's new protocol, via theRS-232C communication port, enables the SEG-2550 tobe used in a sophisticated post production system withthe BVE-900.There are two remote control modes for SEG-2550: E-Filemode and DIRECT mode. The former provides the editingcontroller with control of E-File operations (will beavailable) and the latter provides the editor with basiccontrol of SEG-2550.Interface with an external computer viaRS-232CThe SEG-255O can be controlledcomputerfrom an externalsuch as the SMC- 7OG via RS-232Ccommunication port. There are following remote controlmodes for SEG-255O: E-File, DIRECl;SAVE (E-File memorytransfer from SEG-255O to computer), and LOAD (E-Filememory transfer from computer to SEG-255O) available tobe programmed.While the SEG-255O is remotelycontrolled by the BVE-9OO or an external computer, thedisplayed.Trigger out connectionThe E-File "TAKE" command can be remotely controlleavia trigger connector from the SMC- 70G and SMW- 7076Q-manager.4. A FULLY INTEGRATED E.File SYSTEMSony's unique E-Filesystemmemoryis an eventfunctionwhich stores all ofthe data from thetransitionseffectsswitcher.andof theThe exact sameeffectscreatedmanually, includingselected video, wipe patterns, setting of switches, etc., arememorized and can be reproduced later. For E-Fileoperations such as memorizing, recalling, and execution,a display monitor is required. All of the data memorizedare displayed in 3 pages in this display. A maximum of 63effect events can be memorized and displayed on theCRI The accumulated transition time of events is limitedto approx. 6 minutes. During rehearsal, all switchingoperations can be memorized beforehand. The storeddata can also be correctedin the EDIT MODE. The E.fileoperation is possible with the SEG-2550 control panel, andalso from the external computer or edit controller via anRS-232C communicationsDSPindication(3 pages)The data is shown by 3pages.

5. OTHER FEATURESIntegral sync generatorThe SEG-2550 has an integral sync generator whichmeets the RS-170A standardare used for the synchronization(NTSC). A black burst signalsof the equipmentconnected to the SEG-2550. If a reference black burstsignal or VBS signal i~ supplied to the gen-lock inputconnector, the SEG-2550 will be synchronized withexternalequipment.Easy SC/H phase adjustmentBoth H and SC/H phase between the SEG-2550 and eachinput 1 through 8 can be individually adjusted byobserving the phase indication pattern displayed on thepreset monitor. Without the need for a waveform monitoror vectorscope, adjustments are quick and easy.H phase adjustmentTally and intercom facilityFour inputs of tally/intercom connectors are equipped toprovide two way communication between the operator ofthe SEG-2550 and camera operator. The tally lamp of thecamera selected will automatically light up.The intercom volume is adjustable from the control panelof the SEG-2550.19-inch rack mountableThe SEG-2550 can be mounted in a 19-inch EIA rack tocomplement your existing studio system. The unit is 7rack units high.Torque adjustableThe torque of the effects levers can be adjusted as theoperator desires.Interface capability with CRK-2000The SEG-2550 can be directly interfaced with theCRK-2000 which provides a chroma keyer input to theSEG-2550.REAR PANEL OF SEG-2550
