This H.264 Encoder IP core has been developed to be the highest throughput standards compliant hardware H.264 video compressor.
The IP offers two encoder variants to meet the different targets of features.
The IP include 2 mode.
H264E-I: H.264 encoder compliant with CAVLC 4:4:4 Intra Profile (all frames are keyframes)
The IP core is smaller but yields less compression. It does not require external memory.
H264E-P: H.264 encoder compliant with High 4:4:4 Predictive Profile:
The IP core is larger but offers a significantly better compression.
Both share the same outstanding processing speed of more than 5.2 pixels encoded per cycle.
The data interfaces in the H.264 Encoder IP Core use the AXI industry standard.
The Master I/O data interfaces use an AXI3 bus, forward compatible with AXI4 interconnects.
ITU-R_BT is a digital video encoder with integrated colour-space converter. The encoder accepts 24-bit RGB pixels from sequential odd and even fields. These pixels are then mapped to the YCbCr colour-space and formatted correctly into a BT output stream.
The output of the encoder generates an industry standard ITU-R BT.656 format video stream together with a video_val signal that is asserted with the first valid byte of the output stream.
