Abstract

A system (200) and method (300) provide an efficient communication system for distributing digital multimedia/HDTV signals to multimedia units in a cellular pattern. The method includes: 1) using at least a first primary wide area-antenna for, where selected, transmitting a digital multimedia/HDTV signal per frequency allocation over at least a portion of a predetermined reception area, wherein a plurality of patterns of cells tesselates the predetermined reception area; and 2) using cell-site antennas having transmitters, each located in a cell, for, where selected, transmitting, when the primary wide area-antenna is deselected, at least a first preselected digital multimedia/HDTV signal over an area of the cell, for providing the HDTV signal to a plurality of digital receivers in accordance with a predetermined scheme, wherein the digital multimedia/HDTV signal is associated with a predetermined frequency allocation.

B) cell-site antennas having transmitters, each located in a nonATM framework cell, for, where selected, transmitting, when the primary wide-area antenna is deselected, at least a first preselected digital ATV signal over an area of the cell, wherein one of B1-B2;

B1) signals different from at least the first preselected digital ATV signal are transmitted in different cells in the frequency allocation of a single ATV signal; and

B2) at least the first preselected digital ATV signal is transmitted in different cells in the frequency allocation of a single ATV signal;

C) a plurality of ATV/HDTV signal digital receivers, configured for receiving at least a portion of the first digital ATV signal from one of;

the primary wide-area antenna and the cell-site antennas and providing multimedia program selection for the ATV signal in accordance with a predetermined scheme, wherein the ATV signal is associated with a predetermined frequency allocation.

2. The system of claim 1 wherein the at least first digital multimedia signal is a TDMA formatted signal comprised of multiple information sources.

3. The system of claim 2 wherein the receiver selects one of the multiple information sources.

4. The system of claim 1 wherein the portion of the first digital multimedia signal includes one of:

A) the entire first digital multimedia signal; and

B) multiple information sources.

5. The system of claim 1 wherein the wide-area transmitter and cell site transmitters are configured to be responsive to the multimedia program selection requests by the receivers by providing selected multimedia programs in accordance with a predetermined bandwidth scheme.

6. The system of claim 5 wherein the predetermined bandwidth scheme includes:

A) prioritizing the multimedia program selection requests in accordance with a number of multimedia program requests per multimedia program;

B) transmitting a first predetermined number of multimedia programs receiving a highest number of requests using a preselected bandwidth; and

C) transmitting a second predetermined number of multimedia programs receiving fewer requests using at least one other bandwidth that is less than the preselected bandwidth.

7. A bandwidth-efficient, non-Asynchronous Transfer Mode (non-ATM) framework communication system for distribution of wireless high-definition television, HDTV, signals in a cellular pattern, comprising:

A) at least a first primary wide-area antenna having a transmitter located in the reception area, for, where selected, transmitting a HDTV signal per frequency allocation over at least a portion of a predetermined reception area, wherein a plurality of patterns of cells tesselates the predetermined reception area;

B) cell-site antennas having transmitters, each located in a nonATM framework cell, for, where selected, transmitting, when the primary wide-area antenna is deselected, at least a first preselected HDTV signal over an area of the cell, wherein one of B1-B2;

B1) signals different from the at least first preselected HDTV signal are transmitted in different cells in the frequency allocation of a single HDTV signal; and

B2) at least the first preselected digital multimedia signal is transmitted in different cells in the frequency allocation of a single HDTV signal;

C) a plurality of digital ATV/HDTV signal receivers, configured for receiving at least a portion of the first HDTV signal from one of;

the primary wide-area antenna and the cell-site antennas and providing multimedia program selection for the HDTV signal in accordance with a predetermined scheme, wherein the HDTV signal is associated with a predetermined frequency allocation.

8. The system of claim 7 wherein the at least first digital multimedia signal is a time-division multiplexed formatted signal comprised of multiple information sources.

9. The system of claim 8 wherein the receiver selects one of the multiple information sources.

10. The system of claim 7 wherein the portion of the first digital multimedia signal includes one of:

A) the entire first digital multimedia signal; and

B) multiple information sources.

11. The system of claim 7 wherein the wide-area transmitter and cell-site transmitters are configured to be responsive to the multimedia program selection requests by the receivers by providing selected multimedia programs in accordance with a predetermined bandwidth scheme.

12. The system of claim 11 wherein the predetermined bandwidth scheme includes:

A) prioritizing the multimedia program selection requests in accordance with a number of multimedia program requests per multimedia program;

B) transmitting a first predetermined number of multimedia programs receiving a highest number of requests using a preselected bandwidth; and

C) transmitting a second predetermined number of multimedia programs receiving fewer requests using at least one other bandwidth that is less than the preselected bandwidth.

13. A method for broadcasting a digital signal to distribute wireless multimedia/high-definition television in a non-Asynchronous Transfer Mode (non-ATM) framework communication system, HDTV/ATV signals in a cellular pattern, comprising:

A) using at least a first primary wide-area antenna having a transmitter located in the reception area, for, where selected, transmitting a digital multimedia/HDTV/ATV signal per frequency allocation over at least a portion of a predetermined reception area, wherein a plurality of patterns of cells tesselates the predetermined reception area; and

B) using cell-site antennas having transmitters, each located in a non-ATM framework cell, for, where selected, transmitting, when the primary wide-area antenna is deselected, at least a first preselected digital multimedia/HDTV/ATV signal over an area of the cell, wherein one of B1-B2;

B1) signals different from the at least first preselected digital multimedia/HDTV/ATV signal are transmitted in different cells in the frequency allocation of a single digital multimedia/HDTV/ATV signal; and

B2) at least the first preselected digital multimedia/HDTV/ATV signal is transmitted in different cells in the frequency allocation of a single digital multimedia/HDTV/ATV signal;
