Title:
CONTENT TRANSMISSION APPARATUS AND CONTENT TRANSMISSION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/138075
Kind Code:
A1
Abstract:
A content transmission apparatus comprises: a first encryption process means that encrypts, by means of a digital communication interface, a digital content for transmission to a content reception apparatus and encrypts a low-resolution content by means of a first encryption process; a second encryption process means that encrypts a high-resolution content by means of a second encryption process; and a down-conversion means that down-converts the high-resolution content to the low-resolution content. The content transmission apparatus receives, from a digital reception apparatus, information related to an encryption process of the digital reception apparatus. Then, if the digital reception apparatus supports the second encryption process, the content transmission apparatus transmits the high-resolution content as encrypted by the second encryption process means. If the digital reception apparatus does not support the second encryption process, the content transmission apparatus down-converts the high-resolution content and encrypts, by means of the first encryption process, the down-converted content for transmission.
