Abstract

In an aspect, a method and a system are provided to improve data transmission. In an aspect, the transmitted data is broadcasted. Data is compiled on reported factors that cause data transmission errors and predictions are compiled on unreported factors that cause data transmission errors. In an aspect, the data transmission error factors include regional factors including terrain, environmental factors including weather, atmospheric conditions, sunspot activity and season, radio frequency propagation including Keplerian elements, and retransmission factors. In an aspect, data error correction is employed based on the reported factors and on the predicted factors.

Claims

1. A method comprising:

compiling data on reported factors that cause data transmission errors;

predicting unreported factors that can cause data transmission errors;

transmitting the data to be transmitted to at least one receiver.

2. The method as in claim 1, wherein the compiling data on the reported factors and on the unreported factors comprises collecting data that can effect data transmission on a path to the at least one receiver, and collecting data on at least one of regional data, environmental data, atmospheric data, sunspot activity and season, radio frequency propagation data, and retransmission factors.

3. The method as in claim 1, wherein the compiling data on reported factors comprises at least one of continuously collecting data and collecting data at predetermined events that can effect data transmission.

4. The method as in claim 1, wherein the predicting unreported factors comprises at least one of continuously predicting and predicting at predetermined events that can effect data transmission.

5. The method as in claim 1, wherein the employing error correction comprises employing at least one of forward error correction and carouselling, and adjusting at least one of bandwidth and Quality Of Service (QOS).

6. The method as in claim 1, wherein the employing error correction comprises dynamically adjusting error correction.

7. The method as in claim 1, wherein the transmitting comprises broadcasting data.

8. The method of claim 1, wherein the transmitting the data comprises utilizing at least one of wireless conventional ground terrestrial transmission, digital television (DTV) connection, analog and digital cable television (CATV), satellite connection, direct broadcast satellite system (DBS), wide area network (WAN) connection, and formats chosen by the Advanced Television Systems Committee (ATSC) and the National Television Standards Committee (NTSC).

9. An apparatus comprising:

an error correction engine to compile data on reported factors that cause data transmission errors, predict and compile unreported factors that can cause data transmission errors, and employ error correction on data to be transmitted, based on at least one of the data on the reported factors and the unreported factors; and

a transmitter, coupled to the error correction engine, to transmit the data to be transmitted to at least one receiver.

10.
