Title:
CONTENT TRANSMISSION APPARATUS, CONTENT TRANSMISSION METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/004978
Kind Code:
A1
Abstract:
While limiting the extent of the spread of content by limiting the number of movable generations to a prescribed number, said content is moved to another device. Content-movement control information consisting of movement-count information (move-count) is conveyed between a source device and a sink device, and the sink device manages the received content with move-count decremented by 1. If move-count is still greater than or equal to 1, the content can be moved again with the sink device using the decremented move-count as the control information for the next move, but when move-count becomes 0, further movement is not possible.
