Title
Design and implementation of multiplexing rate control in broadband access network TV transmission system
Abstract
This paper addresses the implementation architecture and protocol procedure of the dedicated broadband access network TV transmission system. According to application-oriented quality of service (QoS), two alternative rate control schemes for multiple DTV programs transmission are proposed collaborating with MPEG-2 system strategy and IP-base network multiplexing mechanism. As to the network bandwidth utilization, a flexible RTF-based synchronization resilience scheme for VBR transport stream (TS) transmission is realized to ensure the performance requirement for MPEG-2 standard. As to the MPEG-2 system strategy, moreover, a parallel VBR transcoding/encoding rate control algorithm for CBR TS transmission could achieve a consistent picture quality for multiple DTV programs under a constrained fixed-rate network bandwidth. For adapting the variable access network bandwidth, the system main control module can flexibly schedule the available rate control scheme for multiple slave service multiplexers. Experimental results demonstrate that the proposed schemes not only improve the traditional TV broadcast adaptation to Internet, but also achieve a more ideal program picture quality constrained by multi-program parallel multiplexing.
