The inventive method comprises steps of receiving an audio signal with spatial information signal, obtaining location information using the number of time slot and parameter of audio signal, establishing a multi-channel audio signal by applying spatial information signal to down-mix signal, and performing a multi-channel array for a multi-channel audio signal in response to the output channel.
Referring to FIG. 4, the syntax relates to ��FramingInfo�� 401 to represent information for a number of parameter sets and information for a timeslot to which a parameter set is applied.
��bsFramingType�� field 403 indicates whether a frame included in the spatial information signal 105 is a fixed frame or a variable frame. The fixed frame means a frame in which a timeslot position to which a parameter set will be applied is previously set. In particular, a position of a timeslot to which a parameter set will be applied is decided according to a preset rule. The variable frame means a frame in which a timeslot position to which a parameter set will be applied is not set yet. So, the variable frame further needs timeslot position information for representing a position of a timeslot to which a parameter set will be applied. In the following description, the ��bsFramingType�� 403 shall be named ��frame identifier�� indicating whether a frame is a fixed frame or a variable frame.
In case of a variable frame, ��bsParamSlot�� field 407 or 411 indicates position information of a timeslot to which a parameter set will be applied. The ��bsParamSlot[0]�� field 407 indicates a position of a timeslot to which a first parameter set will be applied, and the ��bsParamSlot[ps]�� field 411 indicates a position of a timeslot to which a second or subsequent parameter set will be applied. The position of the timeslot to which the first parameter set will be applied is represented as an initial value, and a position of the timeslot to which the second or subsequent parameter set will be applied is represented as a difference value ��bsDiffParamSlot[ps]�� 409, i.e., a difference between ��bsParamSlot[ps]�� and ��bsParamSlot[ps-1]��. In this case, ��ps�� means a parameter set. The first parameter set is represented as ��ps=0��. And, ��ps�� is able to represent value ranging from 0 to a value smaller than the number of total parameter sets.
(i) A timeslot position 407 or 409 to which a parameter set will be applied increases as a ps value increases (bsParamSlot[ps]>bsParamSlot[ps−1]). (ii) For a first parameter set, a maximum value of a timeslot position to which a first parameter set will be applied corresponds to a value resulting from adding 1 to a difference between a timeslot number and a parameter set number and a timeslot position is represented as an information quantity of ��nBitsParamSlot(0)�� 413. (iii) For a second or subsequent parameter set, a timeslot position to which an Nth parameter set will be applied is greater by at least 1 than a timeslot position to which an (N−1)th parameter set will be applied and is even able to have a value resulting from adding a value N to a value resulting from subtracting a parameter set number from a timeslot number. A timeslot position ��bsParamSlot[ps]�� to which a second or subsequent parameter set will be applied is represented as a difference value ��bsDiffParamSlot[ps]�� 409. And, this value is represented as an information quantity of ��nBitsParamSlot[ps]��. So, it is able to find a timeslot position to which a parameter set will be applied using the (i) to (iii).
For instance, if there are ten timeslots included in one spatial frame and if there are three parameter sets, a timeslot position to which a first parameter set (ps=0) will be applied is applicable to a timeslot position resulting from adding 1 to a value resulting from subtracting a total parameter number from a total timeslot number. In particular, the corresponding position is applicable to one of timeslots belonging to a range between 1 to maximum 8. By considering that a timeslot position to which a parameter set will be applied increases according to a parameter set number, it can be understood that timeslot positions to which the remaining two parameter sets are applicable are maximum 9 and 10, respectively. So, the timeslot position 407 to which the first parameter set will be applied needs three bits to indicate 1 to 8, which can be represented as ceil{log2(k−i+1)}. In this case, ��k�� is the number of timeslots and ��i�� is the number of parameters.
If the timeslot position 407 to which the first parameter set will be applied is ��5��, the timeslot position ��bsParamSlot[1]�� to which the second parameter set will be applied should be selected from values between ��5+1=6�� and ��10−3+2=9��. In particular, the timeslot position to which the second parameter set will be applied can be represented as a value resulting from adding a difference value ��bsDiffParamSlot[ps]�� 409 to a value resulting from adding 1 to the timeslot position to which the first parameter set will be applied. So, the difference value 409 is able to correspond to 0 to 3, which can be represented as two bits. For the second or subsequent parameter set, by representing a timeslot position to which a parameter set will be applied as the difference value 409 instead of representing the timeslot position in direct, it is able to reduce the bit number. In the former example, four bits are needed to represent one of 6 to 9 in case of representing the timeslot position in direct. Yet, only two bits are needed to represent a timeslot position as the difference value.
Hence, a position information indicating quantity ��nBitsParamSlot(0)�� or ��nBitsParamSlot(ps)�� 413 or 415 of a timeslot to which a parameter set will be applied can be represented not as a fixed bit number but as a variable bit number.
The audio signal decoding apparatus is able to obtain information for a structure of the upmixing unit by extracting channel configuration information from the configuration information 109 included in the spatial information signal 105. As mentioned in the foregoing description, the channel configuration information is the information indicating a configuration of the upmixing unit included in the audio signal decoding apparatus. The channel configuration information includes an identifier that indicates whether an audio signal passes through the signal converting unit. In particular, the channel configuration information can be represented as a segmenting identifier since the numbers of input and output signals of the signal converting unit are changed in case that a decoded downmix signal passes through the signal converting unit in the upmixing unit. And, the channel configuration information can be represented as a non-segmenting identifier since an input signal of the signal converting unit is outputted intact in case that a decoded downmix signal does not pass through the signal converting unit included in the upmixing unit. In the present invention, the segmenting identifier shall be represented as ��1�� and the non-segmenting identifier shall be represented as ��0��.
In the horizontal method, if an audio signal passes through a signal converting unit, i.e., if channel configuration information is ��1��, whether a lower layer signal outputted via the signal converting unit passes through another signal converting unit is sequentially indicated by the segmenting or non-segmenting identifier. If channel configuration information is ��0��, whether a next audio signal of a same or upper layer passes through a signal converting unit is indicated by the segmenting or non-segmenting identifier.
Since X1 passes through the first signal converting unit, channel configuration information is represented as a segmenting identifier ��1��. Since the channel configuration information is represented by the horizontal method in FIG. 6, if the channel configuration information is represented as the segmenting identifier, whether the two signals 601 and 603 outputted via the first signal converting unit pass through another signal converting units is sequentially represented as a segmenting or non-segmenting identifier.
If channel configuration information is ��0��, whether a next audio signal of a same or upper layer passes through a signal converting unit is represented as a segmenting or non-segmenting identifier. So, channel configuration information is represented for the signal X2 of the upper layer.
The audio signal decoding apparatus is able to include the signal arranging unit 809. The signal arranging unit 809 arranges a plurality of downmix signals according to a preset arrangement to upmix the decoded downmix signal 103. In particular, the signal arranging unit 809 arranges M downmix signals into M�� audio signals in an N-M-N channel configuration.
The position information of the timeslot may be represented as a variable bit number. And the position information may include an initial value and a difference value, wherein the initial value indicates the position information of the timeslot to which a first parameter is applied and wherein the difference value indicates the position information of the timeslot to which a second or subsequent parameter is applied. And the initial value may be represented as a variable bit number decided using at least one of the timeslot number and the parameter number. And the difference value may be represented as a variable bit number decided using at least one of the timeslot number, the parameter number and the position information of the timeslot to which a previous parameter is applied. And the method may further include arranging downmix signal for the downmix signal according to a preset method. And arranging the downmix signal may be performed on the downmix signal entering a signal converting unit upmixing two downmix signals into three signals. And if a header is included in the spatial information signal, the downmix signal arrangement may be to arrange the downmix signal using audio signal arrangement information included in configuration information extracted from the header. And information quantity required for mapping an ith audio signal or for arranging an ith downmix signal may be an minimum integer equal to or greater than log2[(the number of total audio signals or the number of total downmix signals)−(a value of the ��i��)+1]. And the arranging of the multi-channel audio signal may further include arranging the audio signal correspondingly to a speaker.
