Difference between Inter and Intra Frame Compression Last Updated : 24 Nov, 2021 Summarize Comments Improve Suggest changes Share Like Article Like Report In Compression, we reduce the size of our data to achieve high efficiency and easy storage. It is quite cumbersome to transfer files having large size so we need to compress it. Compressed file takes less time for data transmission and reduce the cost of storage. Compression Ratio = B1 / B2 where, B1 = Total Numbers of bits required to represent data before compression B2 = Total Numbers of bits required to represent data after compression There are 2 main types of compression: Inter Frame Compression Intra Frame Compression Difference between Inter and Intra Frame Compression : Inter Frame Compression Intra Frame Compression In this, Data Reduction takes place between the frames. It Exploits redundancy between successive frames.In this, Data Reduction takes place within the frames. It exploits redundancy within the frames.It is also known as Temporal redundancy where the image transition is abruptIt is also known as Spatial redundancy where the image transition is block based.It requires more Processing time because the computer needs to look at several frames.It requires less processing time because the computer is dealing with single frame, A few popular inter frame codec are: H.264-A variant of MPEG-4MPEG-4MPEG-2AVCHD-A variant of H.264 AVCXDCAM-Sony's babyXAVC-Sony's new baby A few popular intra frame codec are: MJPEG-JPEGS bunched togetherProres-Apple's favoriteDN*HD-Avid's babyALL-I-Found in the newer DSLRsCinema DNG-Adobe's baby for raw image sequences.

These devices can include computers, servers, printers, and other hardware. Networks allow for the efficient exchange of data, enabling various applications such as email, file sharing, and internet br 14 min read Difference Between IPv4 and IPv6 IPv4 and IPv6 are two versions of the system that gives devices a unique address on the internet, known as the Internet Protocol (IP). IP is like a set of rules that helps devices send and receive data online.
