Appeal No. 2003-1373
Application No. 09/430,631
The disclosed invention relates to a method for generating a
transition stream for transitioning from a first transport stream
to a second transport stream in a substantially seamless manner.
Claims 1 and 18 are the only independent claims on appeal, and
they read as follows:
1. A method for generating a transition stream for
transitioning from a first transport stream to a second transport
stream in a substantially seamless1 manner, said method comprising
the steps of:
decoding a portion of said first transport stream including at
least a target out-frame representing a last image frame of said
first transport stream to be presented;
decoding a portion of said second transport stream including
at least a target in-frame representing a first image frame of said
second transport stream to be presented;
processing, using a pixel domain process, at least one of said
decoded image frames2; and
encoding a plurality of said decoded image frames, including
said target out-frame and said target in-frame, to produce said
transition stream.
18. A method for generating a transition stream for
transitioning from a first transport stream to a second transport
stream in a substantially seamless manner, said method comprising
the steps of:
1 A “substantially seamless” manner is not the same as a
“seamless” manner (brief, pages 3, 12 and 13). It is noted that
this phrase is not repeated in the body of the claim.
2 It appears that this step is bypassed since the last step
of this method claim performs an encoding operation on the
decoded image frames.
