ABSTRACT:
A packet transmitting apparatus for transmitting a content protected with a content protection technique such as DTCP in the form of packets which are widely used, such as IP packets, and for providing diverse EPG information is provided. Metadata of an A/V stream is utilized to control the output mode, encryption mode, and/or addition of an encryption information header of contents such as video, audio, and data contained in the stream (407). This secures interconnection compatibility between a packet transmitting apparatus and a packet receiving apparatus while maintaining secrecy (414). When a content received through digital television broadcasting is used as an A/V stream, a channel is selected from a full transport stream which is received through broadcasting (409) so as to extract and form a partial transport stream for use (410). EPG information can be selected not only from SI information contained in a digital broadcasting signal but from a plurality of information sources, such as EPG-dedicated channels and the Internet (412).
