About Visionary Solutions PacketAV

Visionary Solutions PacketAV is a JPEG 2000-based AV-over-IP platform that pioneered 4K 4:4:4 distribution over standard 1 GbE networks.

PacketAV transmitters and receivers carry 4K60 4:4:4 with low latency using JPEG 2000, the frame-independent wavelet codec. That makes it a popular backbone for broadcast, enterprise and government AV distribution.

The bitrate is the raw signal divided by the JPEG 2000 ratio (≈8:1 here). A 1080p30 4:4:4 source is about 1.49 Gbps raw and roughly 187 Mbps compressed, so one 1 GbE link carries a few streams.

Worked example

A 1080p30 4:2:0 signal is 746.5 Mbps raw; PacketAV’s JPEG 2000 codec compresses it about 8:1, so the stream is about 93.3 Mbps on the network.

Frequently asked questions

What codec does PacketAV use?

JPEG 2000, chosen for low latency, 4:4:4 colour and frame-independent compression.

Does PacketAV do 4K 4:4:4 over 1 GbE?

Yes — that is its signature: full 4K colour on a single 1 GbE link thanks to the compression.

PacketAV vs SDVoE?

PacketAV runs on 1 GbE with JPEG 2000; SDVoE runs on 10 GbE with a lower-ratio codec for near-lossless quality.

What is the difference between raw and stream bitrate?

Raw is the uncompressed signal (width × height × frame rate × bits per pixel); stream is what the codec actually puts on the wire after compression. The compression ratio is raw ÷ stream.

What do 4:4:4, 4:2:2 and 4:2:0 mean?

They describe chroma subsampling — how much colour detail is kept relative to brightness. 4:4:4 keeps full colour (3× bit depth per pixel), 4:2:2 keeps two-thirds, and 4:2:0 keeps half (1.5×).
