2.3.2. Exchanging the Transmission Technology

The HDTV signal occupies a bandwidth of about 5-times of a standard SDTV signal
(refer to Picture 4). In order to natively transmit the HDTV signal from the camera
head to the CCU, the appropriate transmission technology has to be carefully
selected.
Looking at the data rates of an HDTV-signal, it becomes obvious that conventional
analogue triax transmission is not able to transmit such a high-performance signal
without compromise. Therefore, Sony has decided to employ fibre and digital triax
transmission as a standard technology for the HDC-system cameras.
