Abstract
1. Способ кодирования аудиосигнала, причем способ содержит: ! определение количества временных интервалов и количества наборов параметров, причем наборы параметров включают в себя один или несколько параметров; ! создание информации, указывающей положение по меньшей мере одного временного интервала в упорядоченном наборе временных интервалов, для которого применяется набор параметров; ! кодирование аудиосигнала в виде битового потока, включающего в себя кадр, причем кадр включает в себя упорядоченный набор временных интервалов; и ! вставку переменного количества бит в битовый поток, которые представляют положение временного интервала в упорядоченном наборе временных интервалов, где переменное количество бит определяется положением временного интервала. ! 2. Способ декодирования аудиосигнала, содержащий: ! прием битового потока, представляющего аудиосигнал, причем битовый поток имеет кадр; ! определение количества временных интервалов и количества наборов параметров из битового потока, причем наборы параметров включают в себя один или несколько параметров; ! определение информации о положении из битового потока, причем информация о положении указывает положение временного интервала в упорядоченном наборе временных интервалов, для которого применяется набор параметров, где упорядоченный набор временных интервалов включен в кадр; и ! декодирование аудиосигнала на основе количества временных интервалов, количества наборов параметров и информации о положении, ! где информацию о положении представляют переменным количеством бит на основе положения временного интервала. ! 3. Способ по п.2, в котором перем�1. A method of encoding an audio signal, the method comprising:! determining the number of time intervals and the number of parameter sets, the parameter sets including one or more parameters; ! creating information indicating the position of at least one time interval in an ordered set of time intervals for which a set of parameters is applied; ! encoding an audio signal in the form of a bit stream including a frame, the frame including an ordered set of time slots; and! insertion of a variable number of bits into the bitstream, which represent the position of a time interval in an ordered set of time intervals, where the variable number of bits is determined by the position of the time interval. ! 2. A method for decoding an audio signal, comprising:! receiving a bit stream representing an audio signal, the bit stream having a frame; ! determining the number of time slots and the number of parameter sets from the bitstream, the parameter sets including one or more parameters; ! determining position information from the bitstream, wherein the position information indicates a position of a time interval in an ordered set of time intervals for which a set of parameters is applied where an ordered set of time intervals is included in the frame; and! decoding an audio signal based on the number of time slots, the number of parameter sets and position information,! where the position information is represented by a variable number of bits based on the position of the time interval. ! 3. The method according to claim 2, in which
