     periodic broadcast is a cost-effective solution for large-scale distribution of popular videos. regardless of the number of video requests, this strategy guarantees constant worst service latency to all clients. an essential periodic broadcast method is the client-centric approach (cca), which allows clients to use smaller receiving bandwidth to download broadcast data. an enhanced version, namely cca+, was proposed to yield a shorter waiting time. this work further improves cca+ by leveraging client bandwidth for more efficient video broadcast. the new scheme reduces the broadcast latency by as much as 39 % when compared to cca+ and 78 % when compared to cca. we prove the applicability of this new scheme and provide an analytical evaluation to demonstrate the performance advantage, as compared with particular schemes.
