b) Explain the Motion compensation technique in Video compression.
Step by step
Solved in 2 steps
- Video compression techniques allow for the creation of several copies of a video with varying degrees of quality. To what end are you using this strategy?a) Digital communication has made technology more pleasant in today's environment. Discuss the proposed compression techniques for still images.b) Among the coding schemes available in communication systems, remark on the one that tries to minimize data size.Consider a four-hour film to be displayed on a computer at 24 fps. Each frame is 420 x 270 pixels and a 24-bit RGB color encoding is being used How many bytes will be required to represent the whole film?
- Describe the complete JPEG compression processes with the help of a suitable block diagram illustration. State whether a process or component has contributed toward either a lossless or lossy compression.given me solution in computer science, . A movie was shot in 150 fps. The movie lasted for 30mins. The movie was played in a vertical and horizontal pixel of 720 × 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 systemi) Calculate the 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 fila) Digital communication has made technology more pleasant in today's environment. Discuss the compression strategies for still images that have been proposed.b) Discuss one of the coding schemes available in communication systems that seeks to reduce data size by reducing it.
- (b) Mention the key difference between I-frames, P-frames and B-frames in MPEG-2 video compression. (c) Mention two psychological phenomena that have been exploited in JPEG compression.What is the size of an uncompressed 10-second video clip (in full color) if it is filmed in slow motion (120 frames per second) at HD (1,280 x 720 pixels) resolution? What will the size be if it is filmed at 30 frames per second?Suppose 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?
- Digital communication has made technology more tolerable in today's environment, for the following reasons: a) Discuss the many compression techniques for still images that have been proposed.b) Among the coding schemes available in communication systems, remark on the one that tries to reduce data size by decreasing the amount of data that is sent.Compression techniques can be used to make many copies of a video with varied qualities. In a few phrases, explain what this is for.2. If we ignore the audio data in a video file, a video file is just a collection of many individual frames (i.e., images). What is the main reason that a video file can achieve a much higher compression ratio than a file that contains a single image file?
