Abstract

Systems and methods for implementing a communication mode for a communication terminal are provided. An embodiment of a method for implementing a communication mode includes receiving a first type of data over a first type of communication channel, determining that the first type of data is subsequently not available over the first type of communication channel, and responsive to determining that the first type of data is subsequently not available over the first type of communication channel, receiving the first type of data over a second type of communication channel.

Claims

1. A method for receiving data comprising:

determining whether an authorization message has been received, the authorization message being configured to indicate whether an interactive connection is authorized;

receiving a configuration message, the configuration message specifying a type of communication mode;

in response to determining that an authorization message was received, determining the type of communication mode specified in the configuration message;

in response to determining the communication mode specified in the configuration message, receiving a first type of data over a first type of communication channel, the first type of data being received separately from the configuration message;

determining that the first type of data is subsequently not available over the first type of communication channel; and

responsive to determining that the first type of data is subsequently not available over the first type of communication channel, receiving the first type of data over a second type of communication channel and searching for the first type of data in the first type of communication channel,

wherein the first type of communication channel carries data that is transmitted in accordance with a first communication protocol, and the second type of communication channel carries data that is transmitted in accordance with a second communication protocol,

wherein the first type of communication channel is different than the second type of communication channel, and

wherein the first communication protocol is different than the second communication protocol.

2. The method of claim 1, further comprising:

subsequent to receiving the first type of data over the second type of communication channel, determining that the first type of data is available over the first type of communication channel; and

responsive to determining that the first type of data is available over the first type of communication channel, receiving the first type of data over the first type of communication channel.

3. The method of claim 1, wherein the first type of data is broadcast data.

4. The method of claim 1, wherein the first type of communication channel is used in accordance with a first communication standard, and the second type of communication channel is used in accordance with a second communication standard.

5. The method of claim 1, wherein the first type of communication channel carries data that is transmitted in a first type of frames, and the second type of communication channel carries data that is transmitted in a second type of frames.

6. The method of claim 1, wherein the first type of communication channel carries data that is transmitted using a first type of modulation scheme, and the second type of communication channel carries data that is transmitted using a second type of modulation scheme.

7. The method of claim 6, wherein the first type of modulation scheme is quadrature amplitude modulation (QAM) and the second type of modulation scheme is quadrature phase shift keying (QPSK).

8. The method of claim 7, wherein the first type of communication channel is used in accordance with a DOCSIS (Data Over Cable Service Interface Specifications) communication standard and the second type of communication channel is used in accordance with a DAVIC (Digital Audio-Visual Council) communication standard.

9. The method of claim 6, wherein the first type of modulation scheme is quadrature phase shift keying (QPSK) and the second type of modulation scheme is quadrature amplitude modulation (QAM).

10. The method of claim 9, wherein the first type of communication channel is used in accordance with a DAVIC (Digital Audio-Visual Council) communication standard and the second type of communication channel is used in accordance with a DOCSIS (Data Over Cable Service Interface Specifications) communication standard.

11. A method for receiving data at a set top terminal (STT), the method comprising:

receiving an authorization message, the authorization message being configured to indicate whether the STT is authorized for an interactive connection;

receiving a first type of data over a first type of communication channel;

determining that the first type of communication channel is subsequently not functional; and

responsive to determining that the first type of communication channel is subsequently not functional, receiving the first type of data over a second type of communication channel until the first type of communication channel is established so that the first type of data can be received over the first type of communication channel,

wherein the first type of communication channel carries data that is transmitted in accordance with a first communication protocol, and the second type of communication channel carries data that is transmitted in accordance with a second communication protocol,

wherein the first type of communication channel is different than the second type of communication channel, and

wherein the first protocol is different than the second protocol.

12. The method of claim 11, further comprising:

subsequent to receiving the first type of data over the second type of communication channel, determining that the first type of communication channel is functional; and

responsive to determining that the first type of communication channel is functional, receiving the first type of data over the first type of communication channel.

13. The method of claim 11, wherein the first type of data is broadcast data.

14. The method of claim 11, wherein the first type of communication channel is used in accordance with a first communication standard, and the second type of communication channel is used in accordance with a second communication standard.

15. The method of claim 11, wherein the first type of communication channel carries data that is transmitted in a first type of frames, and the second type of communication channel carries data that is transmitted in a second type of frames.

17. The method of claim 16, wherein the first type of modulation scheme is quadrature phase shift keying (QPSK) and the second type of modulation scheme is quadrature amplitude modulation (QAM).

18. The method of claim 17, wherein the first type of communication channel is used in accordance with a DAVIC (Digital Audio-Visual Council) communication standard and the second type of communication channel is used in accordance with a DOCSIS (Data Over Cable Service Interface Specifications) communication standard.

19. A method for receiving data comprising:

determining whether an authorization message has been received, the authorization message being configured to indicate whether an interactive connection is authorized;

receiving a configuration message, the configuration message specifying a type of communication mode;

in response to determining that an authorization message was received, determining the type of communication mode specified in the configuration message;

in response to determining the communication mode specified in the configuration message, receiving a first type of data over a first type of communication channel, wherein the received first type of data is received separately from the configuration message;

determining that the first type of data is not available over the first type of communication channel;

responsive to determining that the first type of data is not available over the first type of communication channel, receiving the first type of data over a second type of communication channel;

determining that the first type of data is available over the first type of communication channel;
