Abstract

Прием множества элементов синтаксиса, которые указывают палитру, которая использовалась для кодирования блока видеоданных, причем множество элементов синтаксиса включает в себя первый элемент синтаксиса, который указывает количество значений палитры для палитры, которые явно сигнализируются в битовом потоке кодированного видеосигнала, причем первый элемент синтаксиса кодируется с использованием одного или более кодов Голомба таким образом, что длина кодированного первого элемента синтаксиса меньше или равна заранее определенному максимальному количеству битов, декодирование множества элементов синтаксиса, включающее в себя декодирование первого элемента синтаксиса с использованием одного или более кодов Голомба, реконструкцию палитры на основании декодированного множества элементов синтаксиса и декодирование блока видеоданных с использованием реконструированной палитры.
