two kinds of the reproduction process (type "1", "2") method. 在图75中,首先,当重放开始时,对静止画面数据进行存取而存储在静止画面缓冲器147中(步骤S61)。 In FIG 75, first, when the reproduction starts, the still picture data to be accessed is stored in the buffer 147, the still picture (step S61). 此时,在1〜3秒中不重放音频数据而成为无声的状态。 At this time, audio data is not reproduced in 1~3 seconds becomes silent state. 接着,判别是否是类型「1」(步骤S62),在是类型fl」的情况下, 对音频数据进行存取,根据图42(B)所示的时间控制数据信息(SPCIT 一TCDI)几时间控制信息来与静止画面数据同步地进行重放(步骤S63)。 Next, it is determined whether the type is "1" (step S62), in the case of type fl ", the audio data access, according to FIG. 42 (B) shown in the time control data information (SPCIT a TCDI) several times control information synchronized with the still picture data reproduced (step S63). 另一方面,在表示类型「1」的情况下,对音频数据进行存取来进行重放(步骤S64)。 On the other hand, in the case of type represents "1", access to audio data playback (step S64). 在该类型「2」的处理中,如图76所示的那样,当通过使用者指令而产生插入时,解释该指令(步骤S65),根据该指令和静止图片页面控制指令信息(SPPI)来进行静止画面的「进到下一幅」、「返回前一幅」的翻页以及「削去」、「扩大」等重放处理(步骤S66)。 In this process type "2" in FIG. 76 that, when inserted by a user generated command, interprets the command (step S65) shown, according to the command and the still picture page control command information (SPPI) to a still picture of "advance to the next one", "before returning a" page-turning and "slashing", "expand", etc. playback processing (step S66). 在该类型「2」中的静止画面的处理中,不与音频信号保持同步,而不会对音频信号的重放产生影响。 In this type "2" in the still image processing, does not keep pace with the audio signal, without an impact on the reproduction of the audio signal. 下面参照图77、图78来对音频解码器129的变形例进行详细说明。 Referring to FIG 77, FIG 78 modification of the embodiment of the audio decoder 129 will be described in detail. 在该变形例中,追加了取样速率变换器143,首先,音频包有格式分解器141进行分解,接着,有声道分离器142分离为各声道的PCM 数据。 In this modified example, the sampling rate converter 143 is added, first, the audio pack 141 exploded format has decomposed, then there are 142 separate channel separator is a PCM data for each channel. 接着,系统控制器132判断由格式分解器141所分解的音频数据的取样频率fs,在取样频率fs是第一系统的48kHz的情况下,把音频数据从声道分离器142通过开关146、 147原封不动地送给D/A变换器144、 145,另一方面,在取样频率fs是第二系统的44.1kHz的情况下,由取样速率变换器143按图78 (A)所示的那样增加取样为第一系统的48kHz,把该音频数据通过开关146、 147送给D/A变换器144、 145。 Subsequently, the sampling frequency fs by the system controller 132 determines the resolver 141 formats audio data is decomposed, in the case where the sampling frequency fs is 48kHz the first system, the audio data from the channel separator 142 through switch 146, 147 intact to the D / a converter 144, 145, on the other hand, in the case where the sampling frequency fs is 44.1kHz the second system, the sampling rate converter 143 in Figure 78 (a) shown above increase 48kHz sampling a first system, the audio data 146, 147 to the D / a converter 144 through the switch 145. 在第一系统的96kHz的情况下,从声道分离器142通过开关146、 147原封不动地送给D/A变换器44、 45,另一方面,在第二系统的88.2kHz的情况下,由取样速率变换器143按图78 (A)所示的那样增加取样为第一系统的96kHz,并通过开关146、 147送给D/A变换器44、 45。 In the case of the first system of 96kHz, 142 146, 147 intact to the D / A converter from the separator through the channel switch 44, 45, on the other hand, when the second system 88.2kHz , sampled by the sampling rate increase as the converter 143 shown in Figure 78 (a) is the first system 96kHz, and 146, 147 to the D / a converter 44, through the switch 45. 因此,D/A变换器144、 145能够仅由第一系统所构成。 Thus, D / A converters 144, 145 can be formed only by the first system. 而且, D/A变换器144、 145的取样频率fs由系统控制器132进行控制。 Further, D / A converter 144, the sampling frequency fs 145 is controlled by the system controller 132. 取代把取样频率fs从第二系统变换为第一系统,可以如图78 (B) 所示的那样,把第一系统的48kHz、96kHz变换为第二系统的44.1kHz、 88.2kHz。 The substituent conversion sampling frequency fs from the second system to the first system, the second system 78 may be as shown in FIG 44.1kHz (B) as shown, the 48kHz, 96kHz conversion of the first system, 88.2kHz. 而且,多声道信号的各声道,即使在取样频率fs是第一系统的情况下,也能如图78 (C)所示的那样,在某个声道是48kHz的情况下,增加取样为96kHz,而把全部的声道都取得一致为96kHz,来进行D/A变换,由此,来提高重放音质。 Further, each of the channels of the multichannel signal, the sampling frequency fs even in the case where the first system, but also in FIG. 78 (C) as shown in the case of a 48kHz channel, increasing the sampling to 96kHz, and the channels all have to agree to 96kHz, to the D / a conversion, thereby improving playback quality of sound. 下面参照图79、图80来对叠印字幕显示著作权信息的重放装置进行说明。 Referring to FIG 79, FIG 80 to the display of the subtitle copyright information
