Abstract

A content transmission apparatus includes: a retaining section adapted to retain a high-definition video image content; a reception section adapted to receive picture frame information transmitted from a content reproduction apparatus; a calculation section adapted to calculate a cutout range based on the received picture frame information; a cutout section adapted to cut out the calculated cutout range from the retained high-definition video image content; and a signaling section adapted to signal an arbitrary picture frame content configured from a result of the cutout to the content reproduction apparatus.

Claims

1. A content transmission apparatus, comprising:

a retaining section adapted to retain a high-definition video image content;

a reception section adapted to receive picture frame information transmitted from a content reproduction apparatus;

a calculation section adapted to calculate a cutout range based on the received picture frame information;

a cutout section adapted to cut out the calculated cutout range from the retained high-definition video image content; and

a signaling section adapted to signal an arbitrary picture frame content configured from a result of the cutout to the content reproduction apparatus.

2. The content transmission apparatus according to claim 1, wherein said calculation section calculates the cutout range for each frame based on the received picture frame information, and

said cutout section cuts out the cutout range calculated for each frame from each frame of the retained high-definition video image content.

3. The content transmission apparatus according to claim 2, further comprising:

a conversion section adapted to convert the definition of the retained high-definition video image content into a full picture frame content; and

wherein

said signaling section delivers the produced full picture frame content.

4. The content transmission apparatus according to claim 2, wherein the picture frame information includes an initial position of the cutout range and a moving amount per unit time.

5. The content transmission apparatus according to claim 4, wherein the picture frame information further includes an enlarging or reducing amount of the cutout range per unit time.

6. A content transmission method for a content transmission apparatus, comprising:

receiving picture frame information transmitted from a content reproduction apparatus;

calculating a cutout range based on the received picture frame information;

cutting out the calculated cutout range from a retained high-definition video image content; and

signaling an arbitrary picture frame content configured from a result of the cutout to the content reproduction apparatus,

carried out by the content transmission apparatus.

7. A program for causing a computer to function as:

a retaining section adapted to retain a high-definition video image content;

a reception section adapted to receive picture frame information transmitted from a content reproduction apparatus;

a calculation section adapted to calculate a cutout range based on the received picture frame information;

a cutout section adapted to cut out the calculated cutout range from the retained high-definition video image content; and

a signaling section adapted to signal an arbitrary picture frame content configured from a result of the cutout to the content reproduction apparatus.

8. A content reproduction apparatus, comprising:

an operation inputting section adapted to input an operation of a user for designating an arbitrary cutout range on a screen of a video image content;

a production section adapted to produce picture frame information based on the inputted operation;

a transmission section adapted to transmit the produced picture frame information to a content transmission apparatus; and

a reception section adapted to receive an arbitrary picture frame content which is signaled from the content transmission apparatus in response to the transmitted picture frame information and whose cutout range designated by the user is cut out from the video image content.

9. The content reproduction apparatus according to claim 8, further comprising:

a conversion section adapted to convert the definition of the received arbitrary picture frame content.

10. The content reproduction apparatus according to claim 9, wherein the picture frame information includes an initial position of the cutout range and a moving amount per unit time.

11. The content reproduction apparatus according to claim 10, wherein the picture frame information further includes an enlarging or reducing amount of the cutout range per unit time.

12. A content reproduction method for a content reproduction apparatus, comprising:

inputting an operation of a user for designating an arbitrary cutout range on a screen of a video image content;

producing picture frame information based on the inputted operation;

transmitting the produced picture frame information to a content transmission apparatus; and

receiving an arbitrary picture frame content which is signaled from the content transmission apparatus in response to the transmitted picture frame information and whose cutout range designated by the user is cut out from the video image content,

carried out by the content reproduction apparatus.

13. A program for causing a computer to function as:

an operation inputting section adapted to input an operation of a user for designating an arbitrary cutout range on a screen of a video image content;

a production section adapted to produce picture frame information based on the inputted operation;

a transmission section adapted to transmit the produced picture frame information to a content transmission apparatus; and

a reception section adapted to receive an arbitrary picture frame content which is signaled from the content transmission apparatus in response to the transmitted picture frame information and whose cutout range designated by the user is cut out from the video image content.

14. A content delivery system configured from a content transmission apparatus and a content reproduction apparatus, the content transmission apparatus including

a retaining section adapted to retain a high-definition video image content,

a reception section adapted to receive picture frame information transmitted from a content reproduction apparatus,

a calculation section adapted to calculate a cutout range based on the received picture frame information,

a cutout section adapted to cut out the calculated cutout range from the retained high-definition video image content, and

a signaling section adapted to signal an arbitrary picture frame content configured from a result of the cutout to the content reproduction apparatus,

the content reproduction apparatus including

an operation inputting section adapted to input an operation of a user for designating an arbitrary cutout range on a screen of a video image content,

a production section adapted to produce picture frame information based on the inputted operation,

a transmission section adapted to transmit the produced picture frame information to the content transmission apparatus, and

a reception section adapted to receive the arbitrary picture frame content signaled from the content transmission apparatus in response to the transmitted picture frame information.
