Title: Data source hand-off in a broadcast-based data dissemination environment
Inventor: COHEN NORMAN H
IPC: H04B7/26
Filed: 2002-06-03
Granted: 2005-06-21
Abstract: A method, system, and apparatus for handing-off data receivers in a broadcast-based data dissemination environment. Data receiver hand-off is carried out between data sources in different data cells broadcasting information of the same category. Furthermore, data cell ranges are based on geographic regions rather than signal strength coverage. Generally, the hand-off process involves acquiring the current receiver location of the data cell range. If the current receiver location is outside the current data cell range, a hand-off controller searches for a new data source encompassing the current receiver location coordinates and having an associated data topic matching the current topic. Once a new data source is found, the hand-off controller subscribes the data receiver to the data source.

Title: Adaptive equalizer method and apparatus for American ATSC system
Inventor: TSUIE YIH-MING
IPC: H04N5/44
Filed: 2002-07-24
Granted: 2005-11-11
Abstract: An adaptive method for sequentially equalizing data sequences, which conforms to the American ATSC standard includes the following steps. Firstly, an adjustment mode for processing one data sequence is determined according to the statistics of equalization errors of the previous data sequence. Secondly, symbols of the data sequence are processed sequentially. For each symbol, an equalized value is obtained using a tap-delay-line filter with reference to a group of parameters. The equalizer coefficients are adjusted using different functions under different adjustment modes. Then, the equalization errors of the data sequence are calculated for determining the adjustment mode and related parameters for processing next data sequence. These steps eliminate inter-symbol interference during multi-path data transmission.
