Abstract: The time until a media decoder is refreshed to produce correct output samples is minimized if an IDR picture is the first picture in a decoding order in each MPE-FEC frame. A system enabling minimization of tune-in delay is described. Aspects of the system include a content encoder for receiving a source signal including first and second bit streams and for encoding the first and second bit streams, the encoded first bit stream including a decoder refresh bit stream and the encoded second bit stream including a media bit stream. A server receives the encoded first and second bit streams and encapsulates the encoded first and second bit streams into packets. An encapsulator then receives the packets and composes a time-sliced multi-protocol encapsultation (MPE) stream by replacing a spliceable picture from the encoded second bit stream.

Abstract translation: 如果IDR图片是每个MPE-FEC帧中的解码顺序中的第一个图片，则媒体解码器被刷新以产生正确的输出样本的时间被最小化。 描述了使调谐延迟最小化的系统。 该系统的各方面包括一种内容编码器，用于接收包括第一和第二比特流的源信号并用于编码第一和第二比特流，编码的第一比特流包括解码器刷新比特流，并且编码的第二比特流包括媒体比特 流。 服务器接收编码的第一和第二比特流并将编码的第一和第二比特流封装成分组。 然后封装器接收分组并且通过从编码的第二比特流中替换可拼接图片来组成时间分片多协议封装（MPE）流。
