Part I

(10 points) Define the following concepts:

Ripping

Frame-rate

Color-depth

Bitmap resolution

Sampling rate

(10 points) How much space is required to store 1 hour of fidelity music if the height of each high-fidelity sound sample is 16 bits, and the sampling rate is 44.1 kHz? Show how you calculated the answer.

(10 points) In a two-column table, indicate the differences between bitmap and vector graphics.

(5 points) Pick a color in RGB color system and represent the color in decimal, binary, and hexadecimal. For instance, a color with decimal representation (0,255,255) has hex representation (00FFFF) and binary representation (0000 0000 1111 1111 1111 1111).

(5 points) Explain how many bits are used to represent a color in a True-color format? How many different color values are represented in True-Color format. Include your calculation.

1 6- (10 points) What is the storage needed to store one video frame with 720x486 resolution in True-color format? If frame rate is 32 fps, how much data is required for one minute of the video?

(10 points) Show the RLE for the following image data. Remember that pixels are scanned in a zigzag fashion.

(5 points) First show the scanned values in a vector/array.

(5 points) Then provide the RLE.

9	9	9	9	9	8	8	8
9	9	9	1	1	1	1	1
3	2	3	3	3	2	2	2
0	0	255	255	255	0	0	0
66	66	66	66	255	255	255	255
5	5	5	5	6	6	6	6
5	5	5	6	6	6	6	6
6	6	6	6	6	6	6	6

(5 points) Explain the difference between lossy and lossless image compression with examples of image file format that suppport each category.

(5 points) what is the difference between speech synthesis and voice recognition technology? What type of audio format supports speech synthesis?
