Formatting and Coding the Audio in the DTTR

Recording of the audio and time-code information in the Digital Television Tape Recorder (DTTR) takes place in an environment that is optimised largely for the digital video information, as the audio information from the four audio channels together represents only 2 percent of that of the video channel and even with the necessary overhead added is about 6 percent of the recorded data. In tape area usage the digital audio is 5 percent of the total with cue audio 4 percent and time-code 3 percent. Within these constraints an impressive level of performance can be achieved however in technical quality, operational flexibility and ruggedness by the use of suitable coding, shuffling and error protection.
