| * <del>s-vid/comp bodge on white hd cam.</del>
| |
| * <del>Fix weird termination issue on the wide cam from York Come Dancing.</del> This seems to be DaVEp169's "5 in". I noticed that If Camera 1 DA is sent to Mux 1,2,3, or 4 and DaVE 1, 2, 3, or 4 is set as an output, the output looks fine. Therefore not a Camera 1 DA termination issue. DaVE 1,2,3,4 in come directly out of DaVE P169 A,B,C,D (ideally, currently DaVE 2 in is permanently set to Camera 2 since DaVE P169 B was unreliable). Since the problem is displayed on the DaVE 1 monitor (attached to DaVE 1 DA) '''''and''' DaVE out it can't be a DaVE 1 DA termination issue.

| I tested this theory thoroughly. Edit 1 DA currently displays colour bars from MAX so I used that. I took three colour bar outputs from Edit 1 DA, and barrelled them to the BNCs which come from cameras 1,2,3 in patch panel 71,72,73. This showed the problem was on Camera 1. Camera 2 is wired up differently from 1 and 3 due to the DaVE P169 B out issue. I swapped over terminators on Camera 1 DA with Camera 2 DA, and DaVE 1 DA wth DaVE 2 DA. In both cases the prblem was still with camera 1.

| | |
| To further confirm theory, from the start I noticed that setting DaVE P169 A out to 7 (Camera 3 DA) and DaVE P169 C out to 5 (Camera 1 DA) caused the problem to be on DaVE's input 3 colour bars, IE from input 5 on DaVE P169. Setting DaVE P169 A out equal to 5 in, and C out equal to 7 in caused the problem to be on DaVE 1 in.
| |
| | |
| I think I can safely say that DaVE P169 is only currently useful as a 7x3 switcher, not an 8x4.
| |
| | |
| Solutions:
| |
| Without rewiring anything we could set up, say, Mux 3 as Camera 1 DA (Mux 1 and 2 go into VT P169 I think, so probably not a good idea to commit them to a camera). We then set DaVE P169 A out to DaVE P169 3 in. So Camera 1 goes to DA, goes to Mux 3, Goes to Dave 3 in, goes to DaVE P169 A out, goes to DaVE 1 in.
| |
| This has the disadvantage of restricting one of the Mux outs.
| |
| | |
| Rewiring DaVE P169 so that DaVE P169 8 in is Camera 1 DA (DaVE P169 in is currently Edit 1 DA, which if needed could be selected on a Mux out). Then output DaVE 8 in to DaVE P169 A out to Dave 1 in.

| I'd be inclined towards the second option since it will be another long-term 'temporary' fix.--[[User:Malcolm.chambers|Malcolm.chambers]] 22:43, 11 November 2009 (UTC)

| '''<u>Important</u>:'''
| |
| | |
| * <del>Look into why DaVE 2 is playing up before monday's practice show.</del> -- Probably similar to old VT P169's problem, It may be repairable by replacing any dodgy capacitors in the power supply, if it is the power supply then it begs the question why is only ONE output unreliable? It's possible, in my opinion, that excessive heat has damaged a component unique to the '2' output. --[[User:Malcolm.chambers|Malcolm.chambers]] 00:18, 1 November 2009 (UTC)
| |
| * <del>Write documentation of video path on this site.</del> Print out 'current' state and blank table for Studio for corrections/changes made since the 'current' state list was updated.
| |
| * Investigate source of high-pitch noise on audio cable from VT PC to sounddesk. I still haven't looked at this.--[[User:Malcolm.chambers|Malcolm.chambers]] 00:18, 1 November 2009 (UTC)
