A picture of the bed you lie on. It has the pads because there will be plenty of amniotic fluid whether during labor due to your bag of water previously being broken spontaneously, by a doctor/nurse/midwife etc. to speed things along, or just before birth as was the case with our last little guy. I've experienced each of the above scenarios.
Attached to this machine with the paper coming from it will be two wide straps with circular shaped monitors that will be secured around your belly. The monitors check for baby's heart rate and also your contractions. Although not always completely 100% accurate due to your own and your baby's movements, it helps to let your doctor know if the contractions are stressful to baby. This is all recorded on that strip of paper by way of squiggly lines. There will also be a blood pressure cuff hooked up to monitor you.
Your blood pressure readings will be viewable on the computer screen.
You'll likely be given an IV which will have fluids to keep you hydrated along with any meds you may need at the time. If you were diagnosed with Group B strep, they'll want to get in at least two doses of antibiotics before baby arrives. If baby arrives sooner than anticipated, you'll likely end up with a slightly longer hospital stay to make sure things are fine with baby.
Again, since it's likely to be a few hours, there's entertainment for you and whomever may be joining you for your birthing experience. By the time the pain kicks in really good, you're likely to forget that this television even exists. You'll have a remote attached to a cord near your bed which may double as a nurse call device.
