摘要
分析了视频ES流私有空间的组成方式,提出了一种基于视频ES流私有空间传输业务数据的方法。单一私有空间所能容纳的数据量较小,业务数据需划分成若干较小数据块后再传输,介绍了此数据块的数据结构。最后通过实验模拟从视频播出稳定性和业务数据传输可靠性两方面验证了此方法的可行性,该方法可以作为当前业务数据传输方法的一种补充。
The composition of video elementary stream user data space is analyzed in this paper, then a method of service data transmission based on video elementary stream user data space is proposed. The capacity of single user data space is limited, The service data is divided into some small data blocks before transmission. The data structure of this data block is described. Finally, the feasibility of the method is verified through simulation experiments from the video broadcasting stability and service data transmission reliability. This method can be used as a supplement of current service data transmission method.
