Supports both 720p and 1080p HD formats:
Definition component video. With integrated cable driving
technology, the GV7700 is capable of transmitting compressed
video at 270Mb/s or 540Mb/s, or uncompressed video at
1.485Gb/s or 2.97Gb/s, over 75Ω coaxial cable, or
differentially over 100Ω twisted pair cable.

Support for both 8/10-bit and 16/20-bit BT.1120
compliant video interfaces, with embedded TRS or
external HVF timing
The GV7700 integrates the High Definition Visually Lossless
CODEC (HD-VLC™) technology, which has been developed
specifically to reduce the transmission data rate of HD
video over both coaxial and unshielded twisted pair (UTP)
cable. This is achieved by encoding the HD video, normally
transmitted at a serial data rate of 1.485Gb/s, to the same
rate as Standard Definition (SD) video, at 270Mb/s serial
data rate.
