Video source produces 620 480 images, interlaced at a field rate of 59.94 hz and full color (24 bpp). you first convert the video to 4: 2: 2 color format representation. • what compression rate do you need to achieve to send this video over a 1.5 mbps line? • what if you started with 4: 1: 1 color (rather than 4: 2: 2 color)?

Write a method named addall that could be placed inside the hashintset class. this method accepts another hashintset as a parameter and adds all elements from that set into the current set, if they are not already present. for example, if a set s1 contains [1, 2, 3] and another set s2 contains [1, 7, 3, 9], the call of s1.addall(s2); would change s1 to store [1, 2, 3, 7, 9] in some order. you are allowed to call methods on your set and/or the other set. do not modify the set passed in. this method should run in o(n) time where n is the number of elements in the parameter set passed in.
