Conclusion

Assume 3 GB required for 1 hour of film. 3 GB = 8 x 3 x 109 bits. 1 hour = 36 x 102 seconds Speed of data transfer required = 8 x 3 x 109 bits divided by 36 x 102 seconds Approx speed indicated = 7 Mbit/s In real life, typical video transfer speed is 3.6 Mbit/s Input = the guest selects a film Process = Film is streamed to TV Output1 = Film is viewed Output 2 = Billing instructions are sent to server Storage = RAM memory because it is the fastest memory but when the power is switched off the memory is erased. Network = Rooms are in two groups of 25. The equipment in each room is connected to a fast switch so that the memory can be transferred as quickly as possible Switch is connected to equipment on the ground floor. Cabling from TV to the switch is copper. Cabling from switch to ground floor is fibre optic because it is fast and wires close together do not interfere with each other. ...read more.
