Abstract

A contents reproduction apparatus has a contents buffer, a contents reproduction unit, a navigation function unit that provides guide in a route to a destination, an output switching unit that selects first audio data outputted from the contents reproduction unit or second audio data outputted from the navigation function unit and outputs the selected audio data to outside, and a streaming control unit that sets a buffer size that is a target value of the data amount of contents data to be accumulated in the contents buffer and controls the contents reproduction unit and the output switching unit. When the data amount of contents data accumulated in the contents buffer is less than the buffer size, a reproduction operation of the contents reproduction unit is stopped in a period in which the second audio data are outputted to outside.

Claims9

Dependent claims

A contents reproduction apparatus that is mounted on a movable object and reproduces content data streamed by wireless transmission, the contents reproduction apparatus comprising:

a content buffer that accumulates the content data;
a content decoder that reproduces the content data stored in the content buffer;
a route navigator that determines a route from a current position to a destination of the movable object;
an output audio-data selector that switches between outputting first audio data from the content decoder to an output speaker and outputting second audio data from the route navigator to the output speaker;
and
a controller configured to set or adjust a buffer size of the content buffer based on information about the route determined by the route navigator and a moving speed of the movable object,
wherein when the output audio-data selector is switched to output the second audio data from the route navigator to the output speaker, if an amount of content data accumulated in the content buffer is less than the buffer size set by the controller, the controller stops the content decoder from reproducing the content data stored in the content buffer while the second audio data is being output to the output speaker.
