Abstract

Сигналы определения структуры данных (сигналы ОСД) для "супераудиокомпакт-дисков" (САКД) подвергают кодированию без потерь, используя кодирование с формированием кадров, с предсказанием и статистическое кодирование. Помимо эффективно кодированных сигналов на САКД приходится запоминать и большое число параметров, т.е. дополнительную информацию. Чем меньше объем памяти, необходимый для дополнительной информации, тем больше общий выигрыш кодирования. Поэтому способы кодирования применяют и к дополнительной информации с целью сжатия (уменьшения) количества данных дополнительной информации. Кадры можно сегментировать, при этом каждый сегмент имеет свои собственные набор коэффициентов фильтра и таблицу вероятности.Международная заявка была опубликована вместе с отчетом о международном поиске.
