Abstract

The disclosure relates to a distribution device and an information device. The distribution device comprises a communication part, a memory part and a controller. The communication part communicates with an external device. The memory part stores a video data. The controller transmits the video data to the external device through the communication part. The controller transmits the video data to the external device based on a request signal from the external device, and the video data includes a predetermined data that is different from the video data.

First claim

What is claimed is:

1. A distribution device, comprising:
a communication part, communicating with an external device;
an encoder;
a memory part, storing a video data; and
a controller, configured to:
receive, from the communication part a request signal from the external device, wherein the request signal comprises a data size of predetermined data and an information of a requested transfer rate, wherein the requested transfer rate is selected by a user from a requested transfer rate menu;
receive, from the communication part the request signal from the external device, wherein the request signal for requesting the video data including the predetermined data having a data size with which a transfer rate of video data becomes greater than or equal to a second threshold value;
add the predetermined data having the data size to the video data, wherein the predetermined data is different from the video data;
transmit the video data to the external device based on the request signal from the external device through the communication part;
transmit the video data including the predetermined data to the external device through the communication part on a basis that a transfer rate of transmitting the video data to the external device becomes less than or equal to a first threshold value; and
transmit the video data without including the predetermined data to the external device through the communication part on a basis that a transfer rate of transmitting the video data to the external device becomes greater than the first threshold value,
wherein the second threshold value is greater than or equal to the first threshold value,
wherein the controller's configured to transmit the video data including the predetermined data having a large data size to the external device through the communication part when the requested transfer rate is low among the requested transfer rate menu, to transmit the video data including the predetermined data having a small data size to the external device when the requested transfer rate is high among the requested transfer rate menu, and to transmit a packet of the video data and a packet of the predetermined data as separate packets to the external device,

wherein the predetermined data is a packet having a data size that is equal to the natural number multiple of the data size of a packet, the data size of the packet comprises a data size of an encoded data received by the encoder,
wherein the natural number's greater than or equal to one,
wherein the controller transmits the video data including the predetermined data to the external device through the communication part on a basis that a transmission of a portion of the plurality of the video data is completed.

2. The distribution device according to claim 1 , wherein
the controller transmits the video data without including the predetermined data to the external device through the communication part when a value of the data size is zero.

3. The distribution device according to claim 1 , wherein
the request signal received from the communication part comprises an information that requests to transmit a plurality of video data, and
the controller transmits the plurality of the video data to the external device through the communication part based on the request signal under a situation that the plurality of the video data is combined.

4. An information device, comprising:
a communication part, communicating with an external device;
an encoder; and
a controller, executing an application that reproduces a video data downloaded from the external device through the communication part,
wherein the controller transmits a request signal to the external device through the communication part under a situation that the application is running in a background, and receives the video data including predetermined data from the external device, wherein the video data including the predetermined data is transmitted from the external device through the communication part on a basis that a transfer rate of transmitting the video data becomes less than or equal to a first threshold value,
the controller transmits the request signal for requesting the video data including the predetermined data having a data size with which a transfer rate of the video data becomes greater than or equal to a second threshold value to the external device through the communication part,
where the request signal received from the communication part comprises a data size of the predetermined data and an information of a requested transfer rate, and the requested transfer rate is selected by a user from a requested transfer rate menu,
wherein the request signal is for requesting the video data including the predetermined data having a data size corresponding to the requested transfer rate,
wherein the controller is configured to transmit the request signal for requesting the video data including the predetermined data having a large data size to the external device through the communication part when the requested transfer rate is low among the requested transfer rate menu, to transmit the request signal for requesting the video data including the predetermined data having a small data size to the external device through the communication part when the requested transfer rate is high among the requested transfer rate menu, to transmit a packet of the video data and a packet of the predetermined data as separate packets to the external device through the communication part, and to transmit the video data without including the predetermined data to the external device through the communication part on a basis that a transfer rate of transmitting the video data to the external device becomes greater than the first threshold value,
wherein the second threshold value is greater than or equal to the first threshold value,
wherein the predetermined data is a packet having a data size that is equal to the natural number multiple of the data size of a packet, the data size of the packet comprises a data size of an encoded data received by the encoder,
wherein the natural number's greater than or equal to one,
wherein the controller transmits the video data including the predetermined data to the external device through the communication part on a basis that a transmission of a portion of the plurality of the video data is completed.

5. The information device according to claim 4 , wherein
the controller transmits the request signal through the communication part in which a value of the data size is set to zero to the external device when requesting the video data without the predetermined data.

6. The information device according to claim 4 , wherein
the controller transmits the request signal through the communication part in which a value of the data size is set to a natural number greater than or equal to one to the external device when requesting the data size including the predetermined data.

7. The information device according to claim 4 , wherein
the controller determines whether the video data or the predetermined data is downloaded for each predetermined data size in the video data downloaded from the external device through the communication part.

8. The information device according to claim 4 , wherein
the controller determines whether the video data or the predetermined data is downloaded based on a portion of data of each predetermined data size in the video data downloaded from the external device through the communication part.

9. The information device according to claim 4 , wherein
the controller converts a format of the video data including the predetermined data downloaded from the external device through the communication part to a reproducible fo
