As video systems move from analog NTSC to HD digital video, it is also important to move with them accurate time stamping, real time text and graphics insertion capabilities. We will explore some of the tradeoffs and benefits between direct video insertion and data insertion into the SDI metadata. We will explore the impact transmission infrastructure has on time accuracy, positional control and data recovery when transporting HD-SDI video from source to destination. Further some the side effects of compression tools used (e.g. JPEG 2000, MPEG, H.264) to accomplish transport will be discussed.Sponsors
