Alma Technologies H.264 encoders stand out for their true H.264 compression efficiency and the perceptually optimized image quality they offer to the viewer. The ITU-T H.264 recommendation, also known as Advanced Video Coding (AVC), is an in-force video compression standard that was developed in response to the growing need for higher compression of moving pictures. It has been leading video applications to a new era for over 10 years. Alma Technologies invested a great R&D effort to develop expertise and produce a series of H.264 semiconductor IP cores that perform exceptionally well in a very wide variety of application requirements.
A very rich and well balanced H.264 feature set is offered, along with six base configurations and more than five key options to fine-tune each. Our portfolio includes Baseline, Main and High profiles encoders, supporting 4:2:0 and 4:2:2 chroma sampling and up to 12-bit per component color depth.
Our H.264 cores are remarkably easy to operate, ready to encode video right out of the box. They have very simple and comprehensive video data and programming interfaces. They accept uncompressed video data in planar, interleaved, or macroblock scan format and output standalone, standard compliant, Annex B NAL byte-stream.
Using the H.264 Encoder cores is simple via an intuitive interface
The Alma Technologies H.264 cores are designed for easy integration in FPGA and ASIC designs. The input and output data interfaces support streaming and allow the external logic to control the data flow. The external memory interface is simple and flexible, with independent requests, read and write data paths. It is also designed to be tolerant to memory delays and latencies, which may be present in a shared memory system architecture.
Top Image Quality
High Performance & Low Power
Our H.264 encoders are designed to achieve high throughput with low clock frequencies. The cores can fit and process Full HD video in low-cost FPGA device families. For example, Full HD 1080p30 video can be encoded in real time using Altera Cyclone III/IV/V or Xilinx Artix-7 devices. In modern ASIC implementations the cores support 4K UHD with remarkable leakage and dynamic power figures.
