Table schema:
CREATE TABLE table_name_47 (broadcasts__tv__1 INTEGER, series VARCHAR, us_release_date VARCHAR)

Question: What is the sum of Broadcasts (TV) 1, when Series is "3 4", and when US Release Date is "27 December 2006"?
SQL: SELECT SUM(broadcasts__tv__1) FROM table_name_47 WHERE series = "3 4" AND us_release_date = "27 december 2006"
