9/4/07 Pat Cook, CTV, came out to assist tracing problems with the control room equipment. <br />Documentation of the video signal flow is from May 2006 and pre-dates the additional <br />equipment installed by Alpha Video. <br />• We traced signal flow to be able to include the new equipment in the documentation. Mr. <br />Cook is updating the flow chart and will have it by September 20. <br />• Confirmed that the phase of the video delay line coming from the Compix CG was <br />correct. The color of graphics was the same whether the CG was brought up directly as a <br />source or accessed via the downstream keyer. <br />• The right side of the 6x1 switcher was unterminated, leading to too high video levels. Mr. <br />Cook will find terminators at CTV and get them to the Cable Television Coordinator to <br />install. <br />• The right side of the frame synchronizer was unresponsive, possibly stuck in a remote <br />mode without the controller available. The Cable Television Coordinator will contact <br />Alpha Video for service. <br />• There appear to be three video delays. The updated flow chart is needed to identify the <br />function of the other two delays and then the phase should be correctly adjusted. <br />During the Cable Committee meeting, Committee members commented that the projector color <br />looked better. During the City Council Work Session, Councilmember Stigney mentioned that <br />the projected image still looked green. <br /> <br />9/12/07 Chuck Pearce, DS Productions, came with a loaner Sanyo projector and took out the <br />City’s ViewSonic projector to send for service. The Crestron controller will not be able to switch <br />input sources from the control room, but the remote control may be used in the chamber to <br />switch between laptop (Computer 1) and program (Video). The Sanyo projector has a slightly <br />different apparent color from the ViewSonic projector, but still overall greenish tint on video. <br /> <br />9/18/07 The Cable Television Coordinator began calibrating the television monitors in the <br />control room. <br />• Calibrated Preview, Camera 1, Camera 2, and Camera 3 monitors to color bars. <br />• Unable to find video controls for the Program monitor. They might need to be accessed <br />through a remote which is currently missing. The cover may need to be removed to <br />access them. Searched the manufacturers web site for documentation on the monitor, but <br />they did not have manuals online for models that old. The calibration is currently off and <br />color bars have a large hue shift. When watching video, there is a large green cast. <br />• The Live Channel monitor only has an RF input, so need an adaptor to get the test signal <br />from the video switcher to the Live Channel monitor to be able to calibrate. <br />• Attempted to calibrate the Test monitor, but the hue control did not have enough range to <br />make color bars look right. Suspect related to the unidentified video delay lines. <br /> <br />9/19/07 The Cable Television Coordinator used the camcorder’s internal color bar generator to <br />record color bars onto tape. <br />• Routed the Sony DCV-30 deck to Input 3 on the Test monitor and played the recording of <br />color bars. Bars looked correct on Test monitor Input 3 coming from the tape. <br />• This indicates that the monitor was correctly calibrated the previous day, and the signal <br />coming in to the monitor from the video switcher has a problem.
