6-9). As depicted in Figure 1, the system of Yen describes receiving from a transmitter
closed captioning text in an output device such as television monitor 131 (col. 4, lines
14-22) which receives signals from a variety of information sources through a passive
tuner 111 (col. 4, lines 34-36). The output device is further described as a television
monitor and a speaker with such a high resolution screen so as to promote viewing of at
least one primary image and a plurality of secondary images (col. 6, lines 12-15). In
addition to traditional broadcast sources, displayed images of Yen may come from other
passive sources such as closed-captioning and other type of subcarrier embedded into
the broadcast signal (col. 8, lines 25-34). Additionally, Yen provides for crosslinking
each information item from both passive and active information sources so that other
information items may be referenced by multiplexer 120, whether the items are from the
same source or different ones (col. 8, lines 57-61). Among the secondary information
sources, the information items that may be crossed linked are websites displayed in the
broadcast show using a hypertext link displayed in closed caption text or other
annotation information (col. 11, lines 4-16).
As described above, Yen teaches the claimed primary words within the close
captioning text as the hypertext link which appear differently from the secondary words
made of the remaining regular text within the close captioning text. The claimed step of
permitting the user of a remote control to select at least a word is also described by Yen
as the recipient of information selects the particular information using input device 132
