读取TS

    实现比较简单，读取188字节的数据即可

/* TS包  */class Packet{public:	// ...		// 读取数据    friend std::istream& Operator>>(std::istream& is, Packet& packet)    {		// 读取        is.read(reinterPRet_cast<char*> (&packet), PACKET_SIZE);        packet.good                = (is.gcount() == PACKET_SIZE && packet.sync == PACKET_SYNC);        return is;    }		// ...};
