    • The method is used for synchronizing a transmitter (1) and a receiver (K0). The transmitter and the receiver operate at a first (f A ) or a third (f B ) clock frequency, respectively. The data generated by the transmitter (1) and the receiver (K 0 ) are transmitted in sections via a transmission link. The transmission link is operated in both directions at a second clock frequency (f prot ). The method comprises a step of clock synchronization between the transmitter and the receiver. To this end, an equalization method is used in which a transmission path (TXP) and a receiver path (RXP) respectively perform a clock cycle counting method, which comprises the following steps: the duration of a FRAME_VALID signal (DV), indicating a particular data transmission phase, in clock cycles of the first or the second clock frequency is ascertained in the transmission path; the duration of the FRAME_VALID signal (FV), indicating a particular data transmission phase, in clock cycles of the third or the second clock frequency is ascertained using a second counter (Z1', Z2') in the receiver path; the clock cycle numbers (ΔTX, ΔRX) respectively ascertained by the two counters are compared; the frequency difference between the operating clock (CLK_SRC) of the transmitter (1) and the operating clock (CLK_DEST) of the receiver (2) is equalized on the basis of the comparison result.
    • 该方法用于同步发射机(1)和接收机(K0)。 发射机和接收机分别以第一(fA)或第三(fB)时钟频率工作。 由发送器(1)和接收器(K0)生成的数据通过传输链路以部分的形式发送。 传输链路以第二个时钟频率(fprot)在两个方向上工作。 该方法包括发射机和接收机之间的时钟同步的步骤。 为此,使用均衡方法,其中传输路径(TXP)和接收机路径(RXP)分别执行时钟周期计数方法,其包括以下步骤:FRAME_VALID信号(DV)的持续时间,指示 在传输路径中确定在第一或第二时钟频率的时钟周期中的特定数据传输相位; 在第三或第二时钟频率的时钟周期中指示特定数据传输阶段的FRAME_VALID信号(FV)的持续时间使用接收机路径中的第二计数器(Z1',Z2')来确定; 分别由两个计数器确定的时钟周期数(?TX,?RX)进行比较; 基于比较结果,均衡发送器(1)的工作时钟(CLK_SRC)与接收器(2)的工作时钟(CLK_DEST)之间的频率差。

    • The encoding and decoding of HOA signals using Singular Value Decomposition includes forming (11) based on sound source direction values and an Ambisonics order corresponding ket vectors (|Υ(Ω5))) of spherical harmonics and an encoder mode matrix (Ξ 0χS ).
