GV7700
The GV7700 is a serial digital video transmitter for High Definition component video. With integrated cable driving technology, the GV7700 is capable of transmitting HD video at a compressed 270Mbps or an uncompressed 1.485Gbps over 75ohm coaxial cable, or differentially over 100ohm twisted pair cable.
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 1.485Gbps, to the same rate as Standard Definition (SD) video, at 270Mbps serial data rate.
At 270Mbps, the effect of cable loss is greatly reduced, resulting in much longer cable transmission. For 75ohm coaxial cable, HD-VLC allows a 1.485Gbps HD signal to be transmitted up to four times the normal reach. In typical video over coaxial installations, when paired with Semtech’s GV7704 HD-VLC receiver, cable distances of up to 500m are possible.
The GV7700 can also be configured to transmit HD video over UTP cable, such as Cat-5e and Cat-6 cable, when HD-VLC encoded at 270Mbps.

In this fifth and final installment of the BlueRiver applications blog series, we’ll look at how two Semtech products lines – Semtech’s BlueRiver® ASIC platform for Pro AV and SDVoE™, and broadcast Serial Digital Interface (SDI) – can enable a unique set of “SDI-over-IP” products and applications.

Whether you are watching an action replay of a baseball game on a giant screen at a stadium, a movie on your large-screen TV or streaming a video on your laptop computer, a high-quality audiovisual (AV) experience is always expected. Ultra-High-Definition Serial Digital Interface (UHD-SDI) and High-Definition Multimedia Interface (HDMI) are two standards for digital AV transmission. UHD-SDI standardizes the transmission of uncompressed and unencrypted digital AV signals over coaxial or fiber optic cables. HDMI is a digital interface for transmitting high-definition, high-speed digital multi-track audio and uncompressed video signals from HDMI-compliant sources to AV displays. Even though they both can transport ultra-high-definition AV signals from a source to a display, HDMI is preferred to connect consumer gadgets such as computers, gaming consoles, Blu-ray/DVD players, televisions, projectors, etc. UHD-SDI is preferred for high-end applications such as professional indoor/outdoor video production and television broadcasts because it supports long-range transmission and a rugged connection with the help of a physical lock mechanism at each end of the cable. UHD-SDI coaxial cable can transfer signals up to 300 feet, whereas HDMI cables struggle with excessive signal degradation even within 50 feet. These two interfaces can be used together via an HDMI-SDI or SDI-HDMI converter. For example, as shown in figure 1, an HDMI display would be used for confidence monitoring of an SDI stream to avoid the need to use specially calibrated SDI-specific displays.
