Overview: SP-frame is a new picture type of H.264 that can be perfectly reconstructed using one of several reference frames. This paper from HP discusses how this property of SP-frame can be exploited for controlling error propagation caused by packet losses. Hewlett-Packard first illustrates the benefits of the scheme through example. Hewlett-Packard then present results for optimized streaming where PSNR performance of proposed usage of SP-frame is compared to that of P-frames only. Results show that SP frames can noticeably reduce distortion caused by packet losses compare to schemes based on P-frames only.
