Based on the fact that the decoding performance behavior of Short-Length LT (SLLT) codes cannot be deduced by the asymptotic analysis, our research team proposed a method that employs a novel performance measurement model and state-of-the-art randomized search algorithm in order to customize the performance of these codes. In this study, our objective is to propose the guideline how to employ the SLLT code customization method to find suitable SLLT codes in rateless coding schemes for different video applications. In order to demonstrate the way how to derive the target performance requirements of customized SLLT post-codes from the decoding performance behavior of corresponding pre-codes and the rate-distortion characteristics of the test video clips, we designed two examples consisting in constructing composite codes suitable for H.264/Advanced Video Coding (AVC) and H.264/ Scalable Video Coding (SVC).
