Terminal apparatus, content transmission method, content transmission program, and content playback system

1. A terminal apparatus comprising:

a first communication section configured to transmit command information, for changing a mode of the in-vehicle apparatus, to an in-vehicle apparatus capable of playing back a content, wherein the command information is transmitted by way of a gateway apparatus, wherein the gateway apparatus is configured to perform communication with the in-vehicle apparatus through a CAN bus;

a second communication section configured to transmit content data to the in-vehicle apparatus; and

a state determination section configured to determine whether the in-vehicle apparatus has been changed to a mode for playing back the content data.

2. The terminal apparatus according to claim 1 , wherein the command information changes the in-vehicle apparatus to a mode for playing back the content data.

3. The terminal apparatus according to claim 1 , wherein the state determination section is configured to determine whether a mode of the in-vehicle apparatus has been changed by monitoring communication of the in-vehicle apparatus on the CAN bus by way of the gateway apparatus.

4. The terminal apparatus according to claim 1 , wherein the first communication section is configured to perform communication with the gateway apparatus through wireless communication.

5. The terminal apparatus according to claim 1 , wherein the second communication section is configured to perform communication with the in-vehicle apparatus through wireless communication.

6. The terminal apparatus according to claim 1 , further comprising an equalizer setting determination section configured to determine setting of an equalizer when input sound is analyzed and the content data is played back,

wherein the first communication section is configured to transmit equalizer setting information determined by the equalizer setting determination section to the in-vehicle apparatus by way of the gateway apparatus.

7. The terminal apparatus according to claim 6 , further comprising a microphone configured to input sound, wherein the equalizer setting determination section is configured to analyze the sound input from the microphone, and determine the equalizer setting.

8. The terminal apparatus according to claim 6 , wherein the equalizer setting determination section is configured to analyze the content data, and determine the equalizer setting.

9. A method of transmitting a content, the method comprising:

in a terminal apparatus:

by way of a gateway apparatus configured to perform communication with an in-vehicle apparatus capable of playing back the content through a CAN bus, transmitting command information, for changing a mode of the in-vehicle apparatus, to the in-vehicle apparatus;

transmitting content data to the in-vehicle apparatus; and

determining whether the in-vehicle apparatus has been changed to a mode for playing back the content data.

10. A non-transitory computer-readable storage medium having stored thereon, a set of computer-executable instructions that when executed by a computer causes the computer to perform steps comprising:

by way of a gateway apparatus configured to perform communication with an in-vehicle apparatus capable of playing back a content through a CAN bus, transmitting command information, for changing a mode of the in-vehicle apparatus, to the in-vehicle apparatus;

transmitting content data to the in-vehicle apparatus; and

determining whether the in-vehicle apparatus has been changed to a mode for playing back the content data.

11. A content playback system comprising:

a terminal apparatus including

a first communication section configured to transmit command information for changing a mode of an in-vehicle apparatus capable of playing back a content, wherein the command information is transmitted by way of a gateway apparatus, wherein the gateway apparatus is configured to perform communication with the in-vehicle apparatus through a CAN bus,

a second communication section configured to transmit content data to the in-vehicle apparatus, and

a state determination section configured to determine whether the in-vehicle apparatus has been changed to a mode for playing back the content data;

the gateway apparatus configured to transmit the command information from the terminal apparatus to the in-vehicle apparatus; and

the in-vehicle apparatus configured to play back the content data transmitted from the terminal apparatus.

12. The terminal apparatus according to claim 1 , wherein in an event the state determination section determines that the mode of the in-vehicle apparatus has not changed, the state determination unit is configured to continuously determine the change in the mode of the in-vehicle apparatus for a predetermined time period.

13. The terminal apparatus according to claim 12 , wherein in an event the state determination section is configured to determine that the mode of the in-vehicle apparatus has not changed within the predetermined time period, the terminal apparatus is configured to notify an error message.
