发明名称 Signal recording apparatus and method and signal reproduction apparatus and method
摘要 A free space detection section (105) detects a free space of a recording medium (104). A recording capacity calculation section (106) calculates a recording capacity necessary for recording a program in the form of a first encoded signal (TS101) on the recording medium (104). A signal control section (107,500) for comparing the free space detected by the free space detection section (105) and the recording capacity calculated by the recording capacity calculation section (106). A signal selection section (102) selects at least one of the first encoded signal (TS101) and a second encoded signal (TS102) according to a result of the comparison by the signal control section (107,500). A recording section (103) records the encoded signal selected by the signal selection section (102) on the recording medium (104). The first encoded signal (TS101) is obtained by compressively encoding the program at a first compression ratio. The second encoded signal (TS102) is obtained by compressively encoding the program at a second compression ratio which is higher than the first compression ratio. <IMAGE>
