it is said that they do not broadcast in hd video in an attempt to increase dvd sales , or because they are planning to release the hd remastered versions again after the widespread adoption of next-generation dvd , and the broadcasting of videos which have been intentionally degraded is a method frequently used by tbs (and its subsidiary , bs-i ) (on the other hand , works produced by mainichi broadcasting system , inc . (mbs ) and chubu-nippon broadcasting co ., ltd . (cbc ), which are affiliates of tbs , have been broadcast in the hd master versions in recent years ). HDのまま放送しないのはDVDの売り上げ増や、次世代DVDが普及した後にHDリマスター版で再び売り出す事を狙ったものと言われており、故意に画質を落とし放送するのはTBS(および子会社のBS-i)で多用される手法である(その一方で系列局の毎日放送(MBS)や中部日本放送(CBC)制作作品では近年になってHDマスターでの放映を実施している)。
