(a) There are TWO (2) types of scanning methods in video and films display technology. Name and briefly explain these methods. Distinguish the implementation of each scanning method. [8 marks] (b) A digital video also known as motion picture, can be defined as a sequence of several scenes. Practically, raw digital video without compression is very large, which would have the data rate over than 240 Mbps. Therefore, it needs to be compressed before being distributed to the consumer. There are TWO (2) type of compression algorithm that can be applied for digital video which are intra-frame compression and inter- frame compression. Describe both of it.
