Appeal No. 2004-0913
Application No. 08/940,760
BACKGROUND
The invention relates to improving data transfer performance over
communications networks. The invention uses a set of transcoding techniques to
encode (or compress) the data and a set of error control schemes to correct errors
occurring during transmission. The selection of particular sets of transcoding and error
control schemes may be based on the data type (e.g., voice, video, or text) of the data
being transmitted. Representative claim 1 is reproduced below.
1. A method for transmitting data over a communications network, the
method comprising the steps of:
determining a data type for the data;
selecting a transcoding technique and an error control scheme to format
the data based on the data type;
encoding the data using the selected transcoding technique; and
applying the selected error control scheme to the encoded data, the
selected error control scheme adding error control information to the encoded
data.
The examiner relies on the following references:
Bresalier et al. (Bresalier) 5,513,181 Apr. 30, 1996
Suzuki et al. (Suzuki) 6,202,188 B1 Mar. 13, 2001
(filed Jul. 2, 1997)
Claims 1-3 and 5-36 stand rejected under 35 U.S.C. § 103 as being unpatentable
over Bresalier and Suzuki.
