# Requirements Deutsche Fassung: [de:requirements](de:requirements) (probably outdated). ### Help We need help(ers) (/volunteers?) to run our setup in each room, mainly to operate cameras but also to operate the video mixer for switching between camera and slides. The organizer is responsible for making these helpers available. See also [ Helfereinführung](HelperIntroduction ) ### AV - The location must have some sort of PA system. Our audio equipment does use XLR outputs, but we do bring adaptors to be able Cinch (RCA) and 3.5mm Mini-Jack if needed. - The location must have some sort of video display. This is usually a projector, but having a large screen also works. Our equipment produces a 1080p ("FullHD") signal via HDMI or SDI. If your display does not support that, please get in contact with us, we have a stockpile of adaptors which we can bring if needed. ### Schedule/Program Our semi-automated editing platform needs the program/schedule in schedule.xml format. These file are produced by the usual conference planning solutions (frab, pretalx, ...) without needing to configure anything. If you want to use pretalx, but don't have the means to run your own instance, you can use [the c3voc pretalx instance](https://pretalx.c3voc.de) or [pretalx hosted](https://pretalx.com). If you don't use any of these tools, we do have some tooling to import spreadsheet files (CSV, ODS, XSLX, Google Docs, ...). See [schedule](schedule) for more details. Of course, building it using your own tools is fine as long as it conforms to the published XSD. ### Network For our systems to work correctly, a wired internet connection is required. We do require IPv4 connectivity, but a NATed connection is fine. Due to the nature of the infrastructure, we cannot provide you with a list of ip addresses we need to connect to. If your network does have restrictions, please ensure we can reach the whole internet on these ports: - **TCP:** 22 (SSH), 80 (HTTP), 443 (HTTPS), 1935 (Stream), 6667 (IRC), 6697 (IRC), 1883 (Mosquitto), 8883 (Mosquitto) - **UDP:** 53 (DNS), 1194 (VPN), 1337 (Stream), 20000-20255 (VPN) - **Optional, additionally for Users:** TCP 143, 587, 993 (Mail), UDP 13337 (VPN), 60000-60100 (Mosh) For streaming to work reliably, an uplink bandwidth of atleast 5mbit/s per room is required. If we do put hardware into more than one room (or if we have a separate office for post-processing), it would be very beneficial to have all the rooms connected to a separate layer 2 segment (separate VLAN is sufficient). We will bring our own router hardware, please do not put a DHCP server in there. ### Design We produce videos in FullHD (1920x1080, 25fps). You should supply us with the following artwork files: - Background image as PNG, optionally as an animation. - **Intro:** This should be either a static PNG or some sort of video which we can use in our generator to create intros. Optionally you can provide us with fully rendered videos for each event/talk that we should provide videos for. - **Outro:** Same as Intro. We can use event/talk-specific intros, but usually we use one conference-wide outro. - When live streaming: - **Break animation:** A looping video that informs the viewers that there's currently no stream running. - Example: - **Break music:** Music that is playing while the break animation is playing. **Must** be royality-free (ideally CC-BY or CC-0) - **design for the live streaming website:** Logo, CSS see and - Some design files for [info-beamer](https://info-beamer.com/) so we can show pretty animations on the projection screens while no talk is running. [Detailed documentation](howto:design-artefakte) ### Insurance The organiser has to pay for potential damage to or loss of the hardware for the duration of the event, including transportation to and from the venue. Since the hardware is relatively expensive, this is usually covered by an event insurance policy. For events within Germany / EU, our equipment is covered by an annual event and equipment insurance framework contract. This policy covers mobile use during events as well as storage and transport, provided certain conditions are met. Should it still be necessary to take out separate insurance, we can provide serial numbers for the hardware upon request. For further details, please refer to [eventhowto#anlieferung_versicherung](eventhowto#anlieferung_versicherung). ### DECT/ Phones (optional) If there is a phone network (Eventphone, microPOC or similar), we need the following extensions and devices: - Office (desk phone): 1561, 1562 - "VOC Helpdesk" (callgroup): 1601 - "VOC Legacy" (redirect to 1601): 1600 - Per hall (replace ''x'' with hall number): - 16x2: "Mixer/ Regie" (desk phone) - optional 16x5: Herald (DECT) - optional 16x1: A/V-Technician (DECT) - optional 16x3: External FoH (DECT or desk phone) This is a simplified version of
