目前,MPEG-Ⅱ/DVB的生产技术已日趋成熟。市场上已有多种MPEG-Ⅱ/DVB系统和编解码产品。但在购买时如何确认和检测该产品是否符合标准,尤其是要确定产品对其他MPEG-Ⅱ/DVB产品的兼容性如何,是一件不太容易的事,必须对所购设备进行相应的测试。尤其是兼容性测试并不是简单地连上一试就能判断是否兼容,而是要对双方的编解码器进行复杂和多次调整。要使多家编解码器同时集中在一起已属不易,要使对自己设备有彻底了解的专家和测试专家一起调测更是困难。因
At present, MPEG-Ⅱ / DVB production technology has matured. There are many types of MPEG-II / DVB systems and codecs available on the market. However, it is not easy to confirm and test whether the product meets the standards at the time of purchase. In particular, it is not easy to determine the compatibility of the product with other MPEG-II / DVB products. The purchased equipment must be tested accordingly . In particular, compatibility testing is not a simple test to determine if it is compatible, but to make complex and multiple adjustments to both codecs. It is not easy to bring together multiple codecs at the same time, making it more difficult for experts and test specialists who have a thorough understanding of their devices to commission them together. because
