Real-Time Software Implementation of H.264 Baseline Profile Video Encoder for Mobile and Handheld Devices

The new video compression standard, H.264/MPEG-4 AVC, promises better rate-distortion performance and compression efficiency over all its predecessors. However, the computational complexity of the H.264 video codec is increased drastically because of inclusion of many new coding, error-resilience and network friendly tools and techniques, which results in it´s implementation for low-end mobile and hand held devices practically difficult. This paper presents fully optimized H.264 baseline profile video encoder to show its suitability for mobile and hand-held applications. Various algorithmic and implementation techniques to optimize H.264 video encoder at low bit-rates are described. The complexity requirements for H.264 video encoder on various low-end processors are presented
