Abstract

Systems and methods are disclosed for mobile television (TV) devices including collapsible antenna structures that are resistant to breaking. The antenna structure allows for a highly mobile antenna/receiver module that can be attached to a standard computer system through a standardized bus interface, such as a USB (universal serial bus) interface. The collapsible antenna is configured to retract into the body of the mobile TV device, as well as to telescope out and articulate (bend) in any direction. The antenna includes strain relief techniques to avoid breakage, for example, a flexible base telescoping segment. The mobile TV device can also include a printed circuit board including an RF (radio frequency) front-end with a tuner, a digital signal demodulator and decoder and a digital bus interface in a single, highly integrated device.

Claims

1. A mobile television device having a break-resistant antenna, comprising:

a device body;

television tuner and demodulator circuitry positioned within the device body to receive and demodulate television broadcast signals;

a telescoping antenna configured to be positioned within the device body when collapsed and configured to be external to the device body when extended, the telescoping antenna comprising;

a flexible base segment; and

a plurality of additional segments that are coupled to the base segment and are successively larger in diameter to provide telescoping; and

an antenna connection mechanism within the device body coupled to the telescoping antenna and to the television tuner and demodulator circuitry.

2. The mobile television device of claim 1, wherein the television tuner and demodulator circuitry is configured to operate with multiple different television broadcast standards.

3. The mobile television device of claim 1, wherein the connection mechanism is configured to allow the telescoping antenna at least to be moved freely within a plane.

4. The mobile television device of claim 1, wherein the connection mechanism is configured to allow the telescoping antenna at least to be freely rotated.

5. The mobile television device of claim 1, wherein the connection mechanism is configured to allow the telescoping antenna to be moved freely within a plane and to be freely rotated.

6. The mobile television device of claim 1, wherein the base segment for the telescoping antenna is coupled to a connector having a pin hole, wherein the connection mechanism is configured to receive the connector and to secure the connector using a pin inserted into the pin hole, and wherein the connector can freely rotate around the pin to allow the telescoping antenna to move freely within a plane.

7. The mobile television device of claim 1, wherein the connection mechanism comprises a conductive sleeve coupled to the device body and a retaining cylinder positioned within the conductive sleeve, wherein the retaining cylinder is also coupled to the telescoping antenna, and wherein the retaining cylinder can freely rotate within the sleeve to allow the telescoping antenna to be rotated freely.

8. The mobile television device of claim 7, wherein the conductive sleeve is cylindrical with at least one flattened edge.

9. The mobile television device of claim 7, wherein the base segment for the telescoping antenna is coupled to a connector having a pin hole, wherein the retaining cylinder comprises a U-shaped end configured to receive the connector and to secure the connector using a pin inserted into the pin hole, and wherein the connector can freely rotate around the pin to allow the telescoping antenna to move freely within a plane.

10. The mobile television device of claim 1, further comprising a bus interface coupled to the television tuner and demodulator circuitry.

11. The mobile television device of claim 9, wherein the bus interface comprises a universal serial bus (USB) interface.

12. The mobile television device of claim 1, further comprising an auxiliary antenna input within the device body and coupled to the television tuner and demodulator circuitry.

13. The mobile television device of claim 1, wherein the telescoping antenna has a cap configured to fit within a recess in the device body when the telescoping antenna is fully collapsed.

14. The mobile television device of claim 1, wherein the device body comprises a releasable cap configured to cover a bus interface connector.

15. The mobile television device of claim 1, wherein the telescoping antenna is configured to receive UHF frequencies when fully collapsed.

16. A method for receiving television broadcasts with a break-resistant antenna, comprising:

providing a device body coupled to a telescoping antenna;

adjusting the telescoping antenna to receive television broadcasts, the telescoping antenna configured to be positioned within the device body when collapsed and configured to be external to the device body when extended, the telescoping antenna further comprising;

a flexible base segment; and

a plurality additional segments that are coupled to the base segment and are successively larger in diameter to provide telescoping;

receiving and demodulating a television broadcast using the telescoping antenna; and

communicating demodulated television broadcast information to an external device.

17. The method of claim 16, wherein the receiving step can be performed with multiple different broadcast standards.

18. The method of claim 16, wherein the adjusting step further comprises moving the telescoping antenna freely within a plane to position it.

19. The method of claim 16, wherein the adjusting step further comprises freely rotating the telescoping antenna to position it.

20. The method of claim 16, wherein the adjusting step further comprises freely rotating the telescoping antenna and moving the telescoping antenna freely within a plane to position it.
