The present invention relates to a content playback apparatus based on a stop time prediction and a content playback method using the same.

In many cases, when the vehicle is driven, the vehicle stands by for a predetermined period of time depending on road conditions such as intersections and congestion zones. Especially, in case of commuting time in big cities, it takes a lot of time compared to the number of stopping time combined.

In addition, there is an inconvenience that the driver must select the content by operating the on-vehicle device and play the selected content in order to view the desired content. In addition, when viewing the contents while driving, the driver is concentrated in watching the contents and does not concentrate on the driving.

Therefore, the driver does not effectively utilize the stopping time that takes much time, and has difficulty in effectively consuming the desired contents.

The present invention proposes a content playback apparatus based on a stop time prediction capable of predicting a predicted stop time and selecting content, and reproducing the content during an actual stop time, and a content playback method using the same.

The step of calculating the estimated time of waiting may include a step of determining an estimated time interval for stopping based on the intersection information or the time constant congestion period information and calculating the estimated time of the stop by summing the time intervals of the estimated congestion period .

The step of calculating the estimated stopping time may further include correcting the estimated stopping time using at least one of commuting time information, day of week information, weather information, and presence / absence of an accident section.

The selecting of the content to be reproduced may include selecting a content whose reproduction time is closest to the estimated expected time from the contents in the reproduction list.

The step of playing the content may include playing the content at a normal speed while the vehicle is stationary, stopping the playback when the vehicle is running, . ≪ / RTI >

The selecting of the content to be reproduced may include selecting a content based on a user's preference in a playlist and selecting a content that can be reproduced within a predetermined speed.

Wherein the step of reproducing the content includes dividing the total reproduction time of the selected content by the estimated expected time to determine a reproduction speed and sequentially reproducing the content each time the vehicle stops at the determined reproduction speed .

The content playback apparatus according to the present invention includes a calculating unit for calculating a path to a destination and calculating a predicted time to a destination, a content selecting unit for selecting content to be played back during the estimated time, And controlling the playback of the selected content during a stopping time while driving to a destination.

The calculating unit may include a stop estimated section determining unit for determining a stop estimated section based on the intersection information or the steady-state congestion period information, a stop estimated time calculating unit for calculating the estimated stop time by adding up the stop- And a correction unit for correcting the estimated time of stopping using at least one of commute time information, day of the week information, weather information, and presence / absence of an accident zone.

The content selection unit may select contents to be reproduced in cooperation with a cloud server or a user terminal.

The control unit may control the content selection unit to select a content having a playback time shorter than the estimated expected time out of contents in the play list and to continuously play the content at a normal speed each time the vehicle stops.

Wherein the control unit selects a content having a playback time longer than the estimated expected time among the contents in the play list and determines a playback speed by dividing the playback time of the selected content by the estimated expected time, It is possible to control the content to be reproduced every time the vehicle stops.
