Television signal receiver

摘要: PROBLEM TO BE SOLVED: To provide the television signal receiver which is adaptive to a plurality of decoders by using as small numbers external terminals and internal processing circuits possible. SOLUTION: This equipped with decoded discrimination part 10 discriminates whether or not an input decoder 8 can be 8. A output switching 9 selects from 7 that inputted terminal controlled 10. Consequently, while increase in circuit scale suppressed, 5 made effectively unless used, adapted decoders. COPYRIGHT: (C)1997,JPO
