H.264 is the digital video codec specified for the Blu-ray (BD) and High-definition DVD (HD DVD) formats. The H.264 specification, which is also known as the Advanced Video Codec (AVC) specification or MPEG 4-Part 10, delivers two to three times the compression efficiency of solutions such as the MPEG-2 standard, which is used in DVD video. H.264 also delivers high-definition video with six times the resolution of standard definition DVDs.

InterVideo's H.264 codec technology leverages highly advanced algorithms to deliver superior quality and performance on today's personal computers. One of the key new features is the ability to divide the decoding tasks among several hardware cores and hardware threads on both the CPU and the GPU. Using traditional single thread decoding techniques, H.264 with high definition would not be feasible on today's personal computers because much of the overall processing power is unused. InterVideo's H.264 codec partitions the decoding tasks through algorithm and data decomposition into multiple threads to use all the processing power of the dual core and hyper threading technologies from Intel and AMD CPUs, as well as the GPU acceleration from NVIDIA graphics hardware.
