Power Reduction in H.264 /Audio Video Codec: A Survey

H.264/AVC video compression standard provides high coding efficiency, but it has high complexity and consumes more power. This paper explains advantages of H.264 audio video codec and why this H.264 technology should be on the shopping list of every business. Digital video streams, especially at high definition (HD) resolution, represent huge amounts of data. In order to achieve real-time HD resolution over typical Internet connection bandwidths, video compression is required. The amount of compression required to transmit 1080p video over a three megabits per second .As compared to other standards (MPEG, H.261, H.262 and H.263) H.264/Audio video codec standard reduces the power as 50mw to 75mw using partial MB (Macro Block) reordering and lossless frame recompression technique. This power will be further reduced to 25mw to 50mw using pipelining technique as a proposed method.
