They are created by decoding the previous frame in the sequence and then using that information to create a new frame. This process is called motion compensation, and it allows for a significant reduction in the amount of data that needs to be transmitted or stored.<\/p>\n<p>D-frames are not as high quality as I-frames, or intra-frames, which are created by capturing a new image from the scene. However, they are much smaller than I-frames, which makes them more efficient to transmit or store.<\/p>\n<p>B-frames, or bi-directional frames, are a type of frame that is created using information from both the previous and the next frame in the sequence. They are used to further reduce the amount of data that needs to be transmitted or stored.<\/p>\n<p>The use of D-frames, B-frames, and other types of frames allows for the efficient transmission or storage of video data. This is important for applications such as video streaming, where the amount of data that can be transmitted or stored is limited.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li>Option A: They generate low resolution picture. This is not correct. D-frames do not generate low resolution pictures. They are used to reduce the amount of data that needs to be transmitted or stored, but they do not affect the resolution of the picture.<\/li>\n<li>Option B: Highly compressed technique. This is correct. D-frames are a highly compressed technique that is used to reduce the amount of data that needs to be transmitted or stored.<\/li>\n<li>Option C: They generate high resolution picture. This is not correct. D-frames do not generate high resolution pictures. They are used to reduce the amount of data that needs to be transmitted or stored, but they do not affect the resolution of the picture.<\/li>\n<li>Option D: None of the above. This is not correct. Option B is the correct answer.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;They generate low resolution picture&#8221; option2=&#8221;Highly compressed technique&#8221; option3=&#8221;They generate high resolution picture&#8221; option4=&#8221;None of the above&#8221; correct=&#8221;option4&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[685],"tags":[],"class_list":["post-19506","post","type-post","status-publish","format-standard","hentry","category-information-theory-and-coding","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What is significance of D-frames in video coding A.
