Question
For the following question, assume that 1GB = 1,000 MB. And remember the difference between Bits and Bytes.
You have been hiking through the arctic with your trusty Siberian Husky "Snowy". All of a sudden you spot a Yeti. You hide behind a snowbank and record a 10 minute video of the yeti with your digital camera. The camera records 4K HDR video at 60fps, at a bitrate of 85Megabits per second. You could be famous! Now you have to get this on social media as quickly as possible. But, since you are in the arctic, your network connectivity is not very fast.
Should you:
- Put the storage medium (a MicroSD card) into the collar of Snowy, and have him deliver it to the nearest hut with an Internet connection (about 7 miles away), where your friends could post the video on your behalf? Siberian Huskies can reach a peak speed of up to 28 mp/h.
- Use the Internet connection of your phone to upload the video (your phone has a transfer rate of about 50Mbps).
- Wait for a scheduled helicopter pickup in 10 minutes and use their onboard Internet connection with a transfer rate of 150Mbps.
Please explain your reasoning step by step.
PLEASE SOLVE THIS ASAP. A different person said C but, isn't A faster? Let me know.

- You are given a text file of size 60 MB, which is to be encrypted using steganography in the low-order bits of each color in an image file. What size image would be required in order to encrypt the entire file? What size would be needed if the file were first compressed to a third of its original size? Give your answer in pixels, and show your calculations. Assume that the images have an aspect ratio of 3:2, for example, 3000 × 2000 pixels.arrow_forward4) An image frame of size 480x7200 pixels. Each pixel is represented by three primary colors red, green, and blue (RGB). Each one of these colors is represented using 8 bits, if we transmit 2000 frames in 8 seconds what is the bit rate for this image?arrow_forwardWhat is a monochrome bitmap? Given a 512 x 512 black-white image, how many bytes are required for its pixel storage?arrow_forward
- A movie was shot in 150 fps. The movie lasted for 30mins. The movie was played in a vertical and horizontal pixel of 720 x 720 respectively. The bit depth for the video was 16 bit. This same video was shot having an audio sampling rate of 44100 Mhz with an audio bit depth of 32bit. The producer of the video decided to test the quality of the audio for the movie with a surround 5.1 channel audio system. audio file size in bits and explain its effect on the video file. ii) Calculate the file size of the video in Megabytes (Mb) iii) Calculate the bit rate of the video file and explain the effect of the value on processing of the file i) Calculate thearrow_forwardNext time you snap a picture, you realize you are capturing millions of pixels into a buffer. The buffer data is read and converted into JPEG in real time. Each pixel in that buffer is an unsigned int (four bytes ): Alpha, Blue, Green, and Red. Let us ignore alpha for now. As you know, a unsigned byte can have a value 0 to 255. In remote sensing jargons, it is called blue channel, green channel, and red channel. Each channel provides valuable information such as, say farm lands, forest fire, drought, landscape, diseases , If a pixel has a value (say in hex) = 0x00a1b1c1 , then 0xc1 is the red pixel, 0xb1 is the green pixel, 0xa1 is the blue and 00 is the alpha. #define RED 1 #define GREEN 2 #define BLUE 3 then, develop a function void calculateSum ( unsigned int *ptr , int count , unsigned char channel , unsigned int *sum, float *average ) { *sum = 0; if (channel == RED ) calculate sum and average for red channel else if (channel == GREEN )…arrow_forwardWe wish to transmit an 8-bit RGBA (red,green,blue,alpha) image with dimensions 1024x1024. How many bits must we transmit to send this image? 2^25 O2^24 O2^27 O None of the provided answers are correct.arrow_forward
- when we view video on a computer the analog video is digitized and stored in the frame buffer of the video frame grabber card.suppose that a vedio is digitized at integer frame rate size 640*480 pixel and bit depth of 24 bit explain why you dont see a flicker effect on your workstation screen when display this video at NTSC frame rate ?arrow_forwardIf we record a song that is one minute long using 16 bits for each sample and is sampled at 44.1 KHz in mono channel, without any metadata or compression, how large would the file be? Express your answer in MB. Show you work. (Note that 1KHz means 1000Hz while 1K means 1024 (and IM means 10242) for capacity calculations.)arrow_forwardSuppose an RGB raster system is to be designed using an 8-inch x 10-inch screen with a resolution of 100 pixels per inch in each direction. If we want to store 12 bits/pixel in the frame buffer, how much storage (in bytes) do we need for the frame buffer?arrow_forward
- Let's say you're interested in transmitting PAL video as a YUV stream. K bits are used to represent each every pixel. What is the minimum bit rate that must be used in order to send this video as: 1. Composite Video. 2. A Video That Is Separated. 3.

Consider a 4 × 4 pixel image with the following brightness values: 15 15 15 15 15 15 13 15 13 13 10 8 10 8 8 3 We will store this image in bits. (a) What is the entropy of this image? What is the number of bits per pixel for the optimum fixed-length coding? This number is our reference for calculating the compression ratio. (b) (c) For this image, what are the average number of bits per pixel and the corresponding compression ratio for the optimum run-length coding? What are the average number of bits per pixel and the corresponding compression ratio for Huffman coding? Compare the compression ratio with that of run-length coding and the entropy.arrow_forward
