- | Another pain point of the current setup is, that we carry a vast amount of items (about 240) to be prepared of basically any lecture room setup, which we have seen in the past years. | + | ==== Goals ==== |
- | But most of the time, the same hardware is connected in the same way, e.g. at the lectern to have slides or the infobeamer on the hall projector. | + | |
- | So the idea is to put the hardware, which is connected the same way basically every time, in their own modules instead | + | High-level goals of the project are: |
- | This would also reduce the time to pack and check everything after the event and might reduce the amount of lost or broken items. | + | |
- | Original Ideas, see https:// | + | * Optimize buildup and tear-down time by reducing the number of indivdiual items |
+ | * Items should be grouped into modules in which the devices are pre-connected | ||
+ | * This reduces wear and tear on connectors, the chance to loose things and the amount of items to track | ||
+ | * The focus should be on the " | ||
+ | * Those use " | ||
+ | * These events usually have too little experience VOC people available | ||
+ | * Big events like Congress and Camp are special, so don't optimize for that! | ||

- | [[howto: | + | |
- | This needs to be extended to incorporate new ideas like using a proper device for the VPN at the hall as well as the upcoming tally lights, which are powered by PoE. | + | |
- | {{drawio> | + | The main purpose of the VOC case is to provide a video stream and recording of lectures: |
+ | |||
+ | * Inputs: | ||
+ | * Slides and speaker laptop audio (stereo) | ||
+ | * 1-3 cameras | ||
+ | * 3-4 microphones for native language | ||
+ | * (optional) 1 translation track (mono) | ||
+ | * (optional) additional video sources on stage | ||
+ | * (Infobeamer) | ||
+ | * Outputs: | ||
+ | * Finished video signal on disk and stream | ||
+ | * Signal for the projector (slides/ Infobeamer/ additional camera) | ||
+ | * Audio-mix for the hall (native audio) | ||
+ | |||
+ | So the recommended signal flow looks like this: {{drawio> | ||
+ | |||
+ | Additional requirements include: | ||
+ | |||
+ | * It shall be possible to " | ||
+ | * Use patch panels where possible to reduce the risk of broken connectors on the devices themselves | ||
+ | * Group items by their place in the hall | ||

+ | ===== Discussions ===== | ||
+ | |||
+ | This section contains information why certain aspects of the setup are defined as described above. | ||
+ | |||
+ | ==== Phones in each Case/ Intercom ==== | ||
+ | |||
+ | At first we wanted to include a second phone in each case, so that we can have a VOC office even when the "regie box" was not shipped to the event. | ||
+ | But we identified some issues with this concept: | ||
+ | |||
+ | * Telephones only provide a benefit, if somebody is near the office phone all the time | ||
+ | * This is probably not the case on small events with only 1-2 lecture rooms and the VOC people will be around in the venue | ||
+ | * An alternative would be to have some DECTs and an RFP in each case. But the handsets would need to arrive charged, somebody has to set it up, etc. | ||
+ | * So this is a lot of effort for diminishing returns and on bigger events there' | ||
+ | * Intercom will be much more useful even on small events | ||
+ | * Better take the space for the phones to have some intercom | ||
+ | * A wired intercom limited to each hall would be enough | ||
+ | |||
+ | ==== Power Input ==== | ||
+ | |||
+ | * Cables attached to the units are a hassle to store properly | ||
+ | * So use PowerCon sockets on the units and store cables separately | ||
+ | * PowerCON TRUE1 TOP vs " | ||
+ | * The new TRUE1 TOP seems like the way to go, *but* the " | ||
+ | * So use the " | ||
+ | |||
+ | ==== Cameras ==== | ||
+ | |||
+ | See above for requirements (most notable a decent motorized zoom range). | ||
+ | |||
+ | * Something like a BMD Studio Camera would remove the need for a preview monitor | ||
+ | * But this would need a separate lens, which needs to be transported properly | ||
+ | * BMD Studio Camera: Has MFT mount with limited choice of suitable lenses | ||
+ | * BMD Ursa: Quite big, transport with lens attached is probably a bad idea -> not suitable for " | ||
+ | * So we're at a camcorder again b/c: | ||
+ | * Single unit | ||
+ | * Easy to operate for new people | ||
+ | * Can also be used handheld quite easily (as a camera on stage) | ||
+ | * Decision: JVC GY-HC500E | ||

- | Options/ Variants: | ||
- | * Use a 4x XLR via CAT 7 cable for the audio between lectern box and audio mixer | ||
- | * Replace the DI box at the lectern by connecting the speaker laptop to the ATEM Mini. The we need an SDI audio de-embedded to get the HDMI or audio jack track to the audio mixing console | ||
- | * Reduces the XLR runs to 2x XLR to the PA | ||
- | * Would need additional XLR cables, if the encoder is placed at the front |
