Implementation in C++ Language of Encoding and Decoding of DSM-CC Protocol in DTV System
Songyu Yu · Jisuanji gongcheng · 2004
By imposing object oriented (OO) method, the paper introduces a regularized mapping rule from pseudo C code of DSM-CC data download protocol syntax to C++ language in DTV transmission and receiving system. Using object oriented programming (OOP) character of C++ language, with the consideration of syntax similarity of DSM-CC protocol stack, this rule can fully employ the idea of polymorphism and inheritance of OOP. With this rule, it gaves an top down C++ implementation of DSMCC. This implementation is highly expansible, compatible for both data carousel (DC) and object carousel (OC), and applicable to both encoding and decoding.
