Low Delay Video Streaming on the Internet of Things Using Raspberry Pi
The emerging ITU-T H.264 video coding standard has been developed to achieve significant improvements over the existing standards in the compression performance. Although the basic coding framework of the standard is similar to that of the existing standards, H.264 introduces many new features. The standard is close to completion, and preliminary tests were reported to give satisfactory results. However, thorough performance evaluations by independent parties have yet to come. In this paper, we provide an independent analysis of the coding performance improvement of H.264 over various other existing video coding standards. Our experiments demonstrated that the H.264 standard can achieve 50% coding gain over MPEG-2, 47% coding gain over H.263 baseline, and 24% coding gain over H.263 high profile encoders.
