Demand-wise check
- 1Concept: on-field decisions referred to the third umpire on a player challenge; limited unsuccessful reviews; 'umpire's call' margin≈35 words
- 2Components: ball tracking (Hawk-Eye, trajectory prediction), Hot Spot (infrared cameras), Snickometer/Real-Time Snicko or UltraEdge (sound), slow-motion replays≈35 words
- 3Silicone tape: Hot Spot detects heat from ball-bat friction; tape on edges may reduce that heat so a faint edge shows no mark≈35 words
- 4Limitation: prediction error in ball tracking, cost, uneven use across series≈35 words

Where marks usually go
- Not explaining the infrared principle behind Hot Spot
- Listing components without what each detects
Draw this
- Labelled diagram: infrared camera → heat mark on bat → third umpire screen
