While XM has thousands of satellite repeaters worldwide, the number of XM terrestrial repeaters has dropped dramatically. Today, a typical city has 20 or more of these stations transmitting on the same frequencies as the satellites. The only difference between these stations and the satellites is their location and frequency. XM makes it easy to find them and use them to your advantage. It also gives you a comprehensive list of all the XM terrestrial repeaters.
In order to maximize the value of the XM approach, the audio channels used in XM are digitally compressed using the CT-aacPlus and AMBE codecs from Coding Technologies. The content is then preprocessed with Neural Audio processors, which are optimized for the aacPlus codec. After pre-processing, the audio is stored in Dalet audio library systems using 384 kbit/s MPEG-1 Layer II. Upon broadcasting, the content is further processed and packaged with additional metadata.
The XM philosophy is built on the constant flow of X-data and O-data. Effective adherence to XM requires companies to capture, analyze, and interpret this data. While each of these two types of data is valuable on its own, the combination of the two helps companies get deeper insights. The following are some common challenges faced by XM implementations: These can range from data silos to poor collaboration. Fortunately, SAP has developed a cloud-native platform to help businesses harness the power of XM.
