Scheduling is YSTV's way of making the [[Computing:WebStream|web stream]] show programming while we're out of the studio - i.e. broadcasting non-live material over the stream in the style of a traditional TV station. It can be used to make YSTV have 24/7 output, and repeat programmes at different times of day for different audiences. It's the origin of the [[hist:Scheduling Managers|Scheduling Manager]] position on the committee, and used to cause many headaches deciding the schedule. | |||
Due to software breakage and incompleteness, YSTV hasn't broadcast from a schedule since 2010. | |||

The main scheduling hardware is provided by the Hedco network mux - the NetMux. | The main scheduling hardware is provided by the Hedco network mux - the NetMux. | ||
This provides two 16 input, single output video muxes, and the same for stereo audio. Currently both video boards are fed from the same video sources from the distribution amplifier. Audio comes from the NetMuxBreakout, and currently only uses the campus network audio layer to feed both stream and network outputs via the compressor. For more details of the wiring see NetMuxWiring. | This provides two 16 input, single output video muxes, and the same for stereo audio.

The network mux is controlled over a serial port from the custom NetMuxController built by Rob. This has a series of preset manual settings (to send live shows, vidserv, clock and inform to net / stream) and the Obey switch that gives the computer control system authority over the system. To cut other sources to net, use the mux front panel (for how, see the NetMux page). | The network mux is controlled over a serial port from the custom NetMuxController built by Rob.

The desk controller is plugged into a USB port on the old office PC which is now used to run SpiDer - the heart of the network control system. This accepts command requests from all the possible control sources (a command line interface and SchedSeven currently), and sets the highest priority requests onto the hardware. | The desk controller is plugged into a USB port on the old office PC which is now used to run [[SpiDer]] - the heart of the network control system.

The firmware within the NetMuxController is currently being updated to move away from using serial emulation over USB to communicating using a lower level access to the USB and a custom protocol. This custom protocol is defined in SpiderUSBProtocol. | The firmware within the NetMuxController is currently being updated to move away from using serial emulation over USB to communicating using a lower level access to the USB and a custom protocol.
