    • A digital television system that includes an RF tuner, a transport stream demultiplexer, an audio decoder, a video decoder, a non-persistent memory, and at least one processor. The non-persistent memory is used to store audio and video packetized elementary stream (PES) packets demultiplexed by the transport stream demultiplexer based upon a broadcast signal received and demodulated by the RF tuner. During the process of decoding and presenting audio, video, and audio-video content on a display device of the television system, the at least one processor generates video records corresponding to each video PES packet and audio records corresponding to each audio PES packet. The video and audio records establish a one to one correspondence between each video PES packet and each audio PES packet and permits each video PES packet and each audio PES packet stored in the memory to be located, decoded, and re-displayed on the display device on the television system.
    • 一种包括RF调谐器,传输流解复用器,音频解码器,视频解码器,非持久存储器以及至少一个处理器的数字电视系统。 非持久性存储器用于基于由RF调谐器接收和解调的广播信号来存储由传输流解复用器解复用的音频和视频分组化基本流(PES)分组。 在电视系统的显示装置上解码和呈现音频,视频和音频 - 视频内容的过程中,至少一个处理器产生对应于每个视频PES分组的视频记录和对应于每个音频PES分组的音频记录。 视频和音频记录在每个视频PES分组和每个音频PES分组之间建立一一对应关系,并且允许存储在存储器中的每个视频PES分组和每个音频PES分组被定位,解码和重新显示在显示设备上 在电视系统上。

    • A computer-implemented method and apparatus for embedding hidden data in an audio signal. An audio signal is received in a base domain and then transformed into a non-base domain, such as cepstrum domain or LP residue domain. The statistical mean manipulation is employed on selected transform coefficients to embed hidden data. The introduced distortion is controlled by psychoacoustic model to ensure the imperceptibility of the embedded hidden data. Scrambling techniques can be plugged in to further increase the security of the data hiding system. The present new audio data hiding scheme provides transparent audio quality, sufficient embedding capacity, and high survivability over a wide range of common signal processing attacks.
    • 一种用于将隐藏数据嵌入音频信号中的计算机实现的方法和装置。 在基本域中接收音频信号,然后将其转换成非碱基域,如倒谱域或LP残基域。 在选择的变换系数上采用统计平均值操纵来嵌入隐藏数据。 引入的失真由心理声学模型控制,以确保嵌入式隐藏数据的不可察觉性。 可以插入加扰技术,进一步提高数据隐藏系统的安全性。 现有的新的音频数据隐藏方案提供透明的音频质量,足够的嵌入容量,以及广泛的常见信号处理攻击的高生存能力。
