The TdPCT 16i/20io-BMD is a hardware interface, software programmable, that provides contact closure inputs and outputs for use in conjunction with Blackmagic Design (BMD) Videohub video routers and/or ATEM Constellation video switchers.
The input section transmits switching commands to a Videohub router or ATEM switcher following the closure of momentary external contacts, memorizing the order of contact closure by means of a First In Last Out (FILO) stack, so as to subsequently restore the routing states in the reverse order of contact closure. It is specifically designed to be used for broadcast camera colour matching & technical control – a feature sometimes referred to as “Touchdown Preview” (when using dedicated contact buttons), while other times “Joystick Preview” or “Joystick Override” (when using the iris control lever contact closure mechanism).
The output section receives the actual status of an ATEM switcher and closes relay contacts in accordance with the video source selection on the PGM and/or PVW bus. It is therefore suitable for situations where a broadcast equipment requires a simple contact closure for its own tally system.
Unlike the Blackmagic Design GPI & Tally interface, both sections can coexist and can operate simultaneously and independently of each other and the output section can be configured to follow a combination of PGM (red) and PVW (green) tallies for where such use is preferred.
Note: the input section always use the Blackmagic Videohub Ethernet Protocol and so – when referring to ATEM switchers – it can only work in conjunction with those ATEM models that have also implemented the Videohub protocol, such as the Constellation series.
Just another software control panel for some * of the Blackmagic Design ATEM video switcher models. Although such thing may seem strange considering the existence of the original, powerful and freely available software control panel from BMD, surprisingly, in my particular use case, there were several reasons why I preferred to build this version of the program – but limited to just basic video sources switching.
* Currently supported models are ATEM SDI, ATEM Television Studio, ATEM Television Studio HD, ATEM 1 M/E Production Studio 4K and ATEM 1 M/E Constellation.
Current Streamstar Live Sports Production And Streaming Solutions have no built-in hardware interfacing solution for “standard” broadcast camera tally light. Such an interfacing means a contact closure for the corresponding on-air camera, via GPI port connected to that camera CCU (or any other GPI-based camera tally solution). Perhaps not such a big issue for the way some studios or broadcasters are working today, but possibly a true problem for those who really need it.
The VifuLens is an interface designed with the aim to provide remote control for B4-mount broadcast lenses and PT(Z) head, using VISCA commands sent over a TCP network. It comprises of a microcomputer connected to the LAN, an analog interface that connects directly to the zoom, focus and iris (ZFI) connectors of the lenses and a RS-232 serial port that connects to the pan and tilt head (PT(Z)). While originally designed for Fujinon broadcast lenses and PTZOptics broadcast pan & tilt head combination, it can be adapted to other scenarios as well.
I started developing this hardware interface and its related software within a specific project I worked on, where a system consisting of several Micro Studio Camera 4K cameras, MTF B4 lens adapters, ZA17x7.6BERD-S6 lenses and PT-610 / PT-BRDCSTR-P PTZ heads had to be installed. The interface turned out to be a necessity, because the PTZ head controller model, which was specifically requested for that project, has been originally designed to connect to remote lens control of compact camcorders, not to independent B4-mount broadcast lenses type which usually equips ENG or EFP cameras.
Year 2026 edit: the PT-610 broadcast pan & tilt head has been discontinued by PTZOptics, lately it was still available from the VHD company and, ultimately, it most likely became a defunct/no-longer-manufactured product. Maybe (?) a good substitute might be the PTR-15 4K Robotic Pan Tilt Head from Datavideo , although I didn’t tried it myself and I also find a bit funny the “4K” claim on a – supposedly – passive video path on such a type of product (but, well, it could be related to the quality of the BNC connectors and the ~half-meter long internal coax cable).
Ever wanted to put the 808 Pureview on a tripod and take a picture of yourself while standing at some distance from the camera ? Now this can be done even more easily than with the built‑in self‑timer !
Notes:
This article refers to Symbian^3 based Nokia mobile phones, in particular 808 PureView and N8 models.
The solution provided here is most suitable when the mobile phone is used in conjunction with a tripod, not with a selfie stick.
The solution provided here is based on a third‑party application installed on phone, used in conjunction with a Bluetooth remote control originally designed to be used with Apple devices; other particular Bluetooth remote controls may work as well, in case they happen to use the same key codes. Feel free to experiment !
It happens that I have an ASUS R700 GPS device. Although a good piece of hardware, ASUS has dropped the software support for it, leaving the users only with map updates possibility from Naviextras web site, but even this one only until 1 May 2016, the date from which map updates support for this device has also been dropped.
The original ASUS GO GPS application provided with the R700 was from the beginning (and remained) a sort of beta version of the Nav N Go iGO GPS application, with poor or broken automatic map overview in 3D mode, occasional software crashes and skipping full support for possibly additional map features on newer map versions. The latest software update from ASUS site occurred in 2008.
