Appeal No. 2002-1162
Application No. 08/683,994
BACKGROUND
Appellants’ invention is directed to a method of
transmitting and receiving compressed television signals that
marks the transmitted signal with position labels at positions
where the transmission of the signal can be resumed after an
interruption. Appellants utilize a transmission strategy in
which a decoder throws away all bits that are delivered by the
network after the “Pause” command has been issued (specification,
page 2). According to Appellants, the server cannot exactly
determine the stream position at the time the pause was affected
at the decoder due to the delay in communication (id.). By
transmitting position labels, decoders can precisely determine
which bits are stored and which ones are to be thrown away after
the “Pause” command is detected wherein the continuation of the
stream involves the request for new bits starting at the
appropriate position label (specification, page 3).
Representative independent claim 1 is reproduced below:
1. A method of transmitting a compressed television
signal, comprising the steps of inserting position labels
into said signal at positions where the transmission of said
signal can be resumed after an interruption, wherein
reproduction of said signal is interrupted upon detection of
a position label after a pause command is received.
