Encoder/decoder for IP video
The Black Box VS-2101X is an H.264/H.265 transceiver that operates as either an encoder or a decoder. It accepts one HDMI input and provides one HDMI output alongside a single Ethernet connection. The unit supports 1920 x 1200 resolution at 60 Hz with 4:4:4 colour sampling. It is designed for AV distribution over standard IP networks.
Power and cabling checklist
Verify that a 5 V/3 A DC locking supply or PoE AF (48 V, 0.25 A) is available at each install location. Confirm the Ethernet infrastructure can carry the encoded stream without bandwidth saturation. Ensure source and display devices match the 100 ohm video impedance and 470 ohm analog audio output impedance specifications.
Sustained streaming behaviour
Latency is specified at 180 ms for 1080p at 60 Hz, which remains consistent during continuous operation. The Level 6 power supply (EN62368-1) maintains stable delivery under constant load. Four status LEDs provide ongoing visibility of power, link and activity without interrupting the video path.

| Feature | Works as Encoder or Decoder The H.264/H.265 HDMI over IP Encoder/Decoder is an HDMI over H.264/H.265 transceiver. This means it can be used as an encoder or a decoder based on the mode selected. It features one HDMI input, one HDMI output, and one Ethernet connection for simplified integration into your AV system. In encoder mode, the HDMI input will be encoded to H.264/H.265 and sent out to the Ethernet port. In decoder mode, the H.264/H.265 data will be decoded from the Ethernet port and sent out the HDMI output. Live Stream Media over IP Extend AV signals as far as your network re |

Questions about this item
Does the VS-2101X ship with a power supply or must I source one separately?
The unit includes a 5 V / 3 A DC locking power adapter (Level 6, EN62368-1) and also supports PoE AF mode at 48 V / 0.25 A, so a separate supply is only needed if you do not use PoE.
Should I choose the H.264 or H.265 operating mode for my 1920 x 1200 at 60 Hz 4:4:4 stream?
Both codecs handle the full 1920 x 1200 60 Hz 4:4:4 signal; H.265 typically delivers the same quality at lower bit-rate, while H.264 offers wider legacy device compatibility.
What does the 180 ms latency figure mean when the repeater is installed in a live AV system?
At 1080p 60 Hz the end-to-end delay is 180 ms, so video and audio arrive roughly one-fifth of a second after the source — acceptable for signage and conferencing but noticeable in interactive gaming.
