The H264-HP-E core from Alma Technologies is an advanced and self-contained ITU-T H.264 High profiles hardware encoder. This core is available in Intra-only [IDR], Light Motion Estimation [LME] and Full Motion Estimation [FME] prediction engine configurations. It supports real time encoding of both single and multiple 4:2:0 and 4:2:2 video streams, in 8-, 10- or 12-bit per component color depth, up to Profile Level 5.2. Encoding in the Constrained Baseline and Main profiles is also supported.

The encoder accepts the uncompressed video data in planar, interleaved, or macroblock scan format. It outputs standalone, standard compliant, Annex B NAL byte stream. No post processing on the output stream, other than (for example) storing, muxing or transmitting, is required. The output NAL byte stream can be decoded, as is, by any ITU-T H.264 compliant decoder that satisfies the Level requirements of the stream and conforms to the corresponding ITU-T H.264 profile.
