Advanced Codec


Streambox utilizes two proprietary video codecs, ACT-L3 and ACT-L5.

  • Streambox’s ACT-L3 codec is an advanced video compression technology optimized for interlaced and progressive video and display systems, ensures compatibility with other Streambox products including Standard Definition (SD) products. This is our legacy codec.
  • Streambox ACT-L5 codec allows the streaming of much higher quality video than is available on other platforms.

Both codecs provide higher quality in 4K, UHD, 2K, HD and SD, at a much lower data rate than MPEG and H.265 compression. Both codecs are
adaptable to user-selectable data rate requirements with constant bit rate and variable bit rate modes.

The robust family of Streambox video transport solutions features innovative error correction and bandwidth shaping technologies which manage, control, and mitigate packet loss and correct irregularities common to video delivery over packet-based networks.
