Since its introduction, several HD Analog formats have emerged, including: HD-SDI, AHD, HD-CVI and HD-TVI. While all HD Analog options offer the same basic benefits compared to analog or IP, each format features a unique set of capabilities and compatibilities. At this time, there is no “standard” format – or established “winner” – in the HD Analog space. But, it is clear that certain formats are better positioned to succeed – offering clear competitive advantages that translate to significant and measurable benefits for the end user.
