Baseline Profile H264 Encoder

Get a Quote

The H264-BP-E silicon intellectual property core is an advanced hardware implementation of the ITU-T H264 Constrained Baseline profile, and supports the real time encoding of video streams up to Profile Level 5.1.

H264-BP-E requires minimal host intervention as it only needs to be programmed once per video sequence. Once programmed, it can encode an arbitrary number of video frames without needing any further intervention or assistance by the host system CPU.

H264-BP-E can accept the uncompressed raw video data in planar, interleaved, or macroblock scan format. It outputs standalone, standard compliant, Annex B NAL byte stream format. No post processing on the output stream, other than saving or transmitting, is required by the host. The output NAL byte stream can be decoded, as is, by any ITU-T H264 compliant decoder that satisfies the level requirements of the stream and conforms to the Constrained Baseline, or higher, ITU-T H264 profile.

The H264-BP-E core implements a simple but yet flexible, requests based, external memory interface with independent read and write data paths. This makes the H264-BP-E independent of memory type supporting, for example, operation with SRAM, SDRAM, DDR, DDR2 and DDR3 types of memory. Glue-less connected external memory controllers are also available. H264-BP-E is designed to be tolerant to memory delays and latencies, which may be present on shared memory system architectures.
