摘要
介绍了HD-SDI音频嵌入技术和解嵌技术的理论依据,以及高清晰度演播室视频标准、数字音频包格式和AES/EBU数字音频格式。运用C++语言编程实现了HD-SDI音频数据的解嵌,提取分析了音频数据包编号、音频数据采样值和音频通道状态块。实验结果表明,该软件可以根据用户的需求多样化实现HD-SDI音频解嵌,在广播电视行业中具有广泛的实用价值。
The theoretical basis of HD-SDI audio multiplex and de-multiplexes relates to the high-definition studio video standards, the digital audio packets＇ format protocols and AES/EBU audio format protocols. Using the C ＋ ＋ programming language, the de-multiplex HD-SDI audio is realized. The audio channel status data, digital audio data packets＇ number and bit assignment of channel status are analyzed. The experimental results show that the software has extensively practical application in radio and TV industry.
