The decoding of the first data (BD data) by the decoder 12b is interrupted, and the mixing of the first sound (parent screen sound) and the second sound (child screen sound) is cancelled.

  Next, in step S3, it is determined whether or not the second data is input from the analog voice. If it is determined in step S3 that the second data is input from the analog voice, the process proceeds to step S5. Specifically, when the second data is input from the first analog AV device 3g (see FIG. 1) or the second analog AV device 3h (see FIG. 1), the first audio ADC 2a (see FIG. 1) or Since it is converted into digital audio by the second audio ADC 2b (see FIG. 1), there is no need for decoding by the second decoder 12b. On the other hand, if it is not determined in step S3 that the second data has been input from the analog voice, the process proceeds to step S4, and decoding of the second data is started using the second decoder 12b. Specifically, when the second data is input from the smartphone 3i, the first digital AV device 3e, or the second digital AV device 3f via the Ethernet (registered trademark) 3d, data decoding is started.

  Next, in step S5, the first sound (parent screen sound) is output from the 5.1ch output unit 16, and the sound (eg, USB sound) as the second decoded data is output from the 2ch output unit 18. Thereafter, the playback automatic switching process from PinP playback is terminated.

  Next, with reference to FIG. 1 and FIG. 12, the detection process of the 2nd data (data transmitted from the smart phone 3i) in step S1 in the reproduction | regeneration automatic switching process of FIG. 11 is demonstrated.

  In step S111, it is determined whether or not the second data transmitted from the smartphone 3i as the DMC (see FIG. 1) is detected. In step S111, this determination is repeated until the second data transmitted from the smartphone 3i is detected. When the second data transmitted from the smartphone 3i is detected, the second data detection process is terminated.

In step S121, this determination is repeated until second data transmitted from the first digital AV device 3e or the second digital AV device 3f is detected, and transmitted from the first digital AV device 3e or the second digital AV device 3f. When the detected second data is detected, the input of the second data ends the detection process. Note that whether or not the second data transmitted from the first digital AV device 3e or the second digital AV device 3f has been detected is determined every 20 milliseconds until the second data transmitted from the digital audio is detected. To be done.

  Next, the second data (analog voice) detection process in step S1 in the automatic playback switching process of FIG. 11 will be described with reference to FIGS.

Specifically, it is determined whether the second data input from the first analog AV device 3g to the first audio ADC 2a or the second data input from the second analog AV device 3h to the second audio ADC 2b is detected. Is done. In step S131, this determination is repeated until the second data is detected in the first audio ADC 2a or the second audio ADC 2b. When the second data is detected in the first audio ADC 2a or the second audio ADC 2b, the second data is detected. The detection process is terminated. Note that whether or not the second data transmitted from the first audio ADC 2a or the second audio ADC 2b is detected is determined every 20 milliseconds until the second data transmitted from the analog audio is detected.

  Next, in step S23, it is determined whether or not an analog voice is input. If it is determined in step S23 that an analog sound has been input, the process proceeds to step S25. Specifically, when the second data is input from the first analog AV device 3g (see FIG. 1) or the second analog AV device 3h (see FIG. 1), the first audio ADC 2a or the second audio ADC 2b Since it is converted to digital audio, there is no need to perform decoding.

  If it is not determined in step S23 that the second data has been input from the analog voice, the process proceeds to step S24, where data decoding is started. Specifically, when the second data is input from the smartphone 3i, the first digital AV device 3e, or the second digital AV device 3f via the Ethernet (registered trademark) 3d, data decoding is started.

  Next, in step S25, the first audio and the audio as the second decoded data are output according to the setting for reproduction (step S21). Specifically, the first audio (parent screen audio) is output from the 5.1ch output unit 16, and the audio (for example, USB audio) as the second decoded data is output from the 2ch output unit 18, or The first audio is output from the 2ch output unit 18, and the audio as the second decoded data is output from the 5.1ch output unit 16.

That is, as shown in FIG. 3, a selection screen 205 as to whether to perform two-stream playback is displayed on the display unit 201.

  Next, in step S212, it is determined whether or not there has been a response from the user to perform two-stream playback. In step S212, if it is determined that there is no response to the user to perform 2-stream playback (the 2-stream playback button 205b in FIG. 3 has not been pressed), the manual playback data setting processing ends. . If it is determined that there is a response indicating that 2-stream playback is to be performed (the 2-stream playback button 205b in FIG. 3 has been pressed), the process proceeds to step S213.

  In step S213, an inquiry is made to the user as to whether to manually reproduce the input data. That is, as shown in FIG. 6, a selection screen 206 for manually reproducing is displayed on the display unit 201. Next, if it is determined in step S214 that there is no response for manually reproducing the input data (the manual button 206a in FIG. 6 has not been pressed), the setting process for manually reproduced data is performed. Exit. If it is determined that there is a response to manually reproduce the input data (the manual button 206a in FIG. 6 has been pressed), the process proceeds to step S215.

  In step S215, an inquiry about the source to be manually played is made to the user. That is, as shown in FIG. 7, a selection screen 208 for a source to be played is displayed on the display unit 201. Next, in step S216, it is determined whether a source for manual reproduction has been designated. Specifically, it is determined whether or not any of the sources numbered 1 to 9 on the selection screen 208 in FIG. 7 has been selected by the user. When a response to the effect that the source to be manually played is specified is received, the process proceeds to step S217.
