Consider a bitmap image with the following specifications and assumptions: Width 1600 Height 1200 pixels Color palette: 24-bit RGB A file header of 54 bytes. a) Compute the size of the image in MB (Mega Bytes) up to 2 decimal places. b) If the image data is saved in an image format that compresses it by 80%, but adds a header of 200 1. bytes, what is the new file size? (Hint: What is compressed: the entire file or just the pixel data?) Consider a video file with the following specifications: Width: 1920 Height: 1080 Frame rate: 60 fps Length: 2 hr 20 mins 2. . . Each frame is stored in 36-bit RGB a) What is the video bit rate per second? b) What is the size of the video file in GB (GigaBytes)? 3. If audio is added to the above video with the following specifications: Sample rate of 44.1 kHz Sampling depth: 16 bits Dolby digital 5.1 surround sound a) What is the audio bit rate per second? b) What is the size of the audio+video file
