'Super Hi-Vision' (SHV) is promising as a future form of television. It is an ultra-high definition TV system that has 16 times the number of pixels of HDTV and employs a 22.2 multichannel sound system. It offers superior presence and gives the impression of reality. The information bitrates of the current prototypes range from 24 to 72 Gbit/s, and a fiber optic transmission system is needed to transfer even just one channel. This paper describes the optical transmission technologies that have been developed for SHV inter-equipment connects and links between outdoor sites and broadcasting stations.

We have manufactured a trial 'Digital Packet Video (PV) Link' system for super high-resolution display. 'Digital PV Link' is a new data transmission protocol where the host transfers video data with attributes for only a selected area such as a motion picture window. This protocol handles the video data with an ID, which can be used for handling between plural hosts and plural displays such as multi display. This ID also makes the display to handle plural windows in accordance with different parameter such as scaling factor, color-adjust, and so on. In this protocol, error handling is a key because the video data is transferred only when the host wants to change display data. So, we have examined transmission errors and capability for motion pictures by using this trial system. In this report, we will introduce the concept and the characteristics of 'Digital PV Link,' and the result of examination.
