Embodiment 1

[0045][Example configuration of content distribution system]

[0046] figure 1 An example configuration of a content distribution system practiced as one embodiment of the invention is shown. The content distribution system includes a content distribution server 30 , and content reproduction terminals 40 - 1 to 40 - n connected to the content distribution server 30 via the Internet 20 . Hereinafter, the content reproduction terminals 40-1 to 40-n are simply referred to as the content reproduction terminal 40 unless otherwise noted.

[0047] The content distribution server 30 stores video content shot in a top-down manner to accommodate the entire space of the imaging object (sports event, concert, etc.). This video content is shot using one or more high-resolution (4000×2000 pixels or higher) video cameras typified by super high-definition (SHV) cameras.

[0048] The content distribution server 30 converts the resolution of the stored high-resolution video content into a pr...

Abstract

The present invention relates to a content transmitting device, a content transmitting method, a content reproducing device, a content reproducing method program, and a content distribution system configured to allow a user to view video content in any image frame desired by the user. The content transmission device according to the first aspect of the present invention has a holding section configured to hold high-resolution video content; a reception section configured to receive image frame information transmitted from the content reproduction device; a calculation section configured to The image frame information calculates a cutout range; a cutout section configured to cut out the calculated cutout range from the held high-resolution video content; and a transmission section configured to send a given image frame composed of a cutout result to The content is sent to the content reproduction device. The present invention is applicable to Internet-based content distribution systems.

Description

technical field [0001] The present invention relates to a content transmitting device, a content transmitting method, a content reproducing device, a content reproducing method, a program and a content distribution system, and in particular to a content transmitting device configured to allow a user to view content in any desired image frame of the content reproducing device, a content reproducing device, and a content reproducing method. Transmission method, content reproducing device, content reproducing method, program, and content distribution system. Background technique [0002] For example, with prior art video content distribution services typified by television broadcasting and Internet-supported video-on-demand systems, viewers can watch video content only in image frames produced by the broadcaster. [0003] It should be noted that video content based on packaged media such as DVD (Digital Versatile Disc) and BD (Blu-ray Disc) includes content in which sports even...
