Current Projects

Revision as of 12:18, 21 May 2012 by Sam.nicholson (talk | contribs) (Added the autocue and updates projects, and some status updates)

This should be a listing of current, ongoing Technical and Computing projects that aren't yet complete enough to merit real documentation. Be warned, this is liable to be outdated and should be used for some idea of what's going on. Also worth a look is the Techie Todo List and the Trac Listings for some of the other ongoing projects.

If you're interested in any of these projects or want to get involved, feel free to email the person listed under the Responsible heading, bearing in mind all YSTV email addresses are of the form where another address isn't listed.

External IMAP

Responsible: Alex Williams

Status: Waiting on response from IT Services

Negotiate with IT Services for an external firewall hole, so that YSTV mailboxes can be read using regular clients or phones from off-campus. At present on-campus works, with this running to completion it's probably worth documenting how to set up external YSTV mail.

DNS Delegation

Responsible: Alex Williams

Status: Awaiting a meeting with IT Services

In theory YSTV could administer our own DNS server, and delegate the zone IT Services manage for us to be managed directly, potentially with access to LanDB for updating our own machines.

Continuous Channel/Scheduling Engine

Responsible: Sam Nicholson

Status: Being written (slowly!)

Write a scheduling and automation tool to allow the Scheduler to come up with shows, and autofill idents, trailers and graphical overlays to make us more like a "real" TV channel. Known as Tarantula.

Easter Refurb

Responsible: Chris Wall, Greg Ebdon, Liz Pasoce, Mike Chislett, Sam Nicholson

Status: Waiting on Estates Services

Still known as the Easter Refurb, despite that holiday being long gone, the plan was to repaint both studio and control room, re-carpet both and generally make the place look nicer. Sort of a tech project.

Currently Chris Teeling (ZFM) has provisionally agreed to fix our blinds but put the floor etc on hold for a little while due to the potential to move into a new space. It should be noted this is a very early stage, the idea to move was mooted but nobody has said yes in any way shape or form. The individuals listed above are working on details.

OB Stream/Receive

Responsible: Sam Nicholson/John Caine

Status: Sender works, receiver needs to be more robust

A computer, labelled YSTVOBSTRM is sent out on OBs. When started up it runs a hidden stream back to YSTV, which is "watched" by YSTVOBSTRMRE inside the control room. This is then fed into the Technical:Vision_Path to either be sent directly to the main stream or inserted into a show. The main advantage is the director/Tarantula can switch to the OB source at the right time rather than taking down the stream, enabling a continuous channel, along with allowing OBs to insert into live shows.

Currently the receiver needs to detect if a stream is there or not and keep trying, so as soon as one comes up it starts receiving. This may also fix the Live Link Laptop's problems. The receiver is also underpowered.

Live Link Laptop

Responsible: Sam Nicholson

Status: Needs more stability testing

Fit up a laptop with a capture device and some cabling, and mount in a rucksack. Then, a camera op fires up the laptop, plugs in a camera and mic and we can live insert from anywhere with wifi!

Greg notes we may have significant issues with cooling, may need to customize a spare rucksack supplied by John.

At present it works with the new YSTV laptop, but roaming between wireless APs causes it to go a bit wrong.

New Muxes

Responsible: Michael Chislett

Status: Power supplies need finishing

Build a pair of chainable 8x8 video matrixes,as prototyped for NaSTA 2011. See the history wiki for more.


Responsible: Michael Chislett

Status: Development hell

The mother of all abstraction layers for the video and audio paths. JAAK will essentially be the auto-router, with simple monitoring of gear statuses. Shiny things JAAK will do:

  • Cope with instruction (graphic touch screen apps) such as "patch studio 92 to DaVE 4". JAAK then goes off and finds the most suitable routing path (shortest and non-conflicting with existing paths).
  • Not need a user manual.
  • Poll serial ports for new YVP compatible devices
    • auto-initiate them.
  • Have an advanced command interface, supporting commands such as DO, WHEN & ON. It will also cope with basic logic and events such as time, and whole system I/O events.
  • JAAK will also detects and avoid (it already can) things such as routing loops.

Video Server Recording

Responsible: Sam Nicholson

Status: Works in theory, largely untested

Write a wrapper to start and stop the Video Server recording live shows over the network.

OB Recording

Responsible: Sam Nicholson

Status: Server written, never tested. Client UI design done

Write a similar wrapper to the video server one for recording on OBs using the capture cards, along with a client to provide a director with record/stream controls, matrix controls, a running order and potentially internal IRC in one handy window.

Archive Server

Responsible: None (stalled)

Status: Part working, see

Write an interface to the Archive server to search for items by name or tag, and retrieve them either by download or to a network drive.

Single Sign On

Responsible: Alex Williams

Status: Proposed

Modify the wikis, forums, webmail etc so that if a user is logged into the website, they also maintain that login through the other online services without having to enter more credentials. Also, automatically logging in to the website if your are logged in with your Server account would be good

Software Updates

Responsible: Greg Ebdon/Sam Nicholson

Status: Proposed

Update all the servers to run the latest stable Fedora immediately prior to the summer break, along with updates to the included packages and other software such as this wiki. Currently requires further research as a database upgrade is needed which can be risky and will require some scheduled downtime.


Responsible: Liz Pascoe/Mike Chislett

Status: Proposed

Build an autocue, see the forum thread for more detail.

Document All The Things!

Responsible: Greg Ebdon

Status: In Progress

Basically, write up documentation on everything YSTV does on here. Big project!
