Seamless Splicing Technology of Transport Streams
Yu Liu · Journal of Tianjin University Science and Technology · 2007
Two seamless splicing methods based on system and elementary level were presented in this paper.The key problems of splicing such as selection of splicing point,synchronization between audio and video,and buffer overflow were also discussed.The system-level-based method has simple arithmetic with fast computed speed,but is not flexible for its high demand of choosing splicing points,while the elementary-level-based method can randomly choose splicing points for its frame-based concept,but it uses transcoding technology which results in complexity of its arithmetic and computation.In our experiments,the output streams using the two methods to splice are all seamless and well compatible with MPEG-2 standard.
