Patent ID: 8620147

Claim:
A method of receiving media data via a digital data interface of a synchronization apparatus from a source apparatus, the method comprising: generating display-related information about a playback capability of the synchronization apparatus in a data structure transceivable via the digital data interface; inserting information about a compressed data playback capability of the synchronization apparatus into the display-related information; transmitting the display-related information from the synchronization apparatus to the source apparatus via the digital data interface of the synchronization apparatus; receiving the media data from the source apparatus, wherein the source apparatus selects the media data based on the display-related information and generates the media data in a data structure transceivable via the digital data interface; extracting compression-related information about compressed data obtained by compressing raw data, from an ancillary data field of the received media data, wherein ancillary data for the raw data has been inserted into the ancillary data field; extracting the compressed data from the received media data; and decoding the compressed data, by using the compression-related information.
