Ntsc bandwidth compression techniques

Web12 nov. 2024 · Abstract Multimedia data, increasing in the modern era because multimedia are the major source of information. Multimedia data required storage capacity and transmission bandwidth. These factors we need for multimedia compression technique. Uncompressed data required more storage and transmission bandwidth on the other … Webassessing the impact of the so-called modulation compression technique. Modulation compression is a lossless compression technique, considered in O-RAN as a key enabler for low-layer splits allowing a dramatic reduction of the required fronthaul capacity without degradation of the signal quality over the fronthaul interface (see [7, §A.5]).
