High definition video can be delivered at a rate of 30 frames per second (fps) where each frame has a resolution of $1920 \times 1080$ pixels using 24 bits per pixel. Can an uncompressed video stream of this format be sent over a USB 1.1 serial port? USB 2.0 serial port? USB 3.0 serial port? (Note: The maximum speeds of USB $1.1,$ USB $2.0,$ and USB 3.0 serial ports are $12 \mathrm{Mbps}, 480 \mathrm{Mbps},$ and $5 \mathrm{Gbps}$ respectively.

Key Concepts

Interface Bandwidth and USB Standards

This concept involves understanding the data transfer limitations and maximum speeds of various communication interfaces, such as USB 1.1, USB 2.0, and USB 3.0. Recognizing the bandwidth specifications of these interfaces is key when determining whether they can support high data rate applications like uncompressed high-definition video streaming.

Frame Rate and Data Rate Calculation

This concept pertains to determining the overall data rate of a video stream by multiplying the data per frame by the number of frames per second. Calculating the video data rate is crucial to assessing if a given communication interface can handle the bandwidth required by the uncompressed video.

Digital Video Resolution and Color Depth

This concept involves understanding how frame resolution and color depth determine the amount of data in each video frame. The resolution (number of pixels) combined with the number of bits used per pixel yields the total amount of data per frame, which is essential for calculating the overall data rate of the video stream.

0:00 Hello.

00:02 So in this problem we have a very high definition video that is running at 30 frames per second.

00:12 And the resolution of this video is 120 multiplied by 180, which is we call nowadays the high definition.

00:24 Okay.

00:26 So each pixel is represented.

00:29 So a pixel is represented.

00:31 Using 24 bits.

00:35 The question here is, can we stream this video without making any compression over usb 1 .1, a usb version 2 and usb version 3? given that the maximum speed of each is as following.

00:56 The usb 1 .1, the maximum speed of 12 megabit per second, and the usb version 2 streams at maximum of 480 megabit per second.

01:16 And finally, the usb 3 is having an output or a maximum output of 5 gigabit per second.

01:26 So the first thing to do here is we need to know how many bits per second should be streamed in order for this video to be played normally without the user noticing this.

01:41 So in each second we need 30 frames to be represented and we multiply this by the total number of pixels.

01:50 The total number of pixels giving this definition, it's simply as getting the area of rectangle.

01:56 Angle so the resolution here is simply the like the width and height of the video and multiplying these numbers together will give us the number of total pixels so 1 ,920 multiplied by 180 and finally we need to multiply by 24 bits because each of this pixel should contain 24 bit...
