Abstract

A device may include a communication interface configured to receive programming information from a service provider multicast over multiple channels. The device may also include logic configured to decode the programming information received over the multiple channels, assemble a programming guide based on the decoded programming information and output the programming guide to an output device for display.

Claims

1. A device, comprising:

a communication interface configured to receive programming information from a service provider multicast over a plurality of channels; and

logic configured to;

decode the programming information received over the plurality of channels,

assemble a programming guide based on the decoded programming information, and

output the programming guide to an output device for display.

2. The device of claim 1, wherein the logic is further configured to:

transmit, via the communication interface, a request to the service provider to join a multicast channel, and

determine whether the programming guide is complete before a predetermined time threshold is reached.

3. The device of claim 2, wherein the logic is further configured to:

request, from the service provider, at least a portion of the programming guide when the programming guide is not complete before the predetermined time threshold is reached.

4. The device of claim 1, wherein when assembling the programming guide, the logic is configured to assemble programming information multicast over a plurality of transmission intervals.

5. The device of claim 1, wherein when assembling the programming guide, the logic is further configured to:

identify sequence number information associated with the decoded programming information, and

assemble the programming guide items using the sequence number information.

6. The device of claim 1, wherein the plurality of channels comprises four channels.

7. The device of claim 6, wherein at least two of the channels comprise programming schedule information and at least one of the channels comprises information other than the programming schedule information.

8. The device of claim 1, wherein the logic is further configured to:

perform error detection on the decoded programming information to detect erroneous data blocks, and

identify missing blocks based on sequence number information associated with the decoded programming information.

9. The device of claim 1, wherein the logic is further configured to:

receive an indication that another device located on a same local area network has attempted to join a multicast channel associated with the service provider, and attempt to join the multicast channel in response to the indication.

10. The device of claim 1, wherein the device comprises at least one of a set top box or a device including a cable or television card configured to receive television programming.

11. A method, comprising:

encoding data for multicast transmission to a plurality of receiver devices;

dividing the encoded data for transmission over multiple channels;

multicasting the encoded data over the multiple channels;

retransmitting the multicasting at a predetermined intervals;

receiving a request from at least one receiver device for information associated with the multicast transmission that is needed by the at least one receiver device; and

unicasting the information to the at least one receiver device.

12. The method of claim 11, wherein the encoded data corresponds to television programming guide information.

13. The method of claim 12, wherein the encoding comprises:

including sequence number information in each data block that is to be transmitted, the sequence number information identifying a relative location of each of the data blocks within a programming guide data file.

14. The method of claim 11, wherein the dividing the encoded data comprises dividing the encoded data over at least four channels.

15. The method of claim 14, wherein the encoding data comprises:

encoding programming schedule information for transmission over at least two of the channels, and

encoding information other than programming schedule information for transmission over at least one channel.

16. The method of claim 15, wherein the information other than schedule information comprises television station logo information, the method further comprising:

transmitting the television station logo information at a slower rate than the programming schedule information.

17. The method of claim 11, wherein the method is implemented as computer-executable instructions embodied on a computer-readable memory device.

18. A system, comprising

at least a first device associated with a service provider, the at least a first device comprising:

first logic configured to;

encode data for multicast transmission, and

divide the encoded data into data blocks for transmission over a plurality of channels; and

a first communication interface configured to;

multicast the encoded data over the multiple channels, and

retransmit the multicasting at a predetermined intervals; and

a second device associated with a customer, the second device comprising;

a second communication interface configured to;

receive the encoded data multicast over the plurality of channels; and

second logic configured to;

decode the encoded data,

assemble a programming guide based on the decoded data, and

output the programming guide to an output device for display.

19. The system of claim 18, wherein the second logic is further configured to:

transmit a request, via the second communication interface, to the service provider, for at least a portion of the programming guide when the programming guide is not complete, and

wherein the first logic is configured to transmit, via the first communication interface, the portion of the programming guide to the second device via a unicast transmission.

20. The system of claim 18, wherein the second device comprises at least one of a set top box or a processing device that includes a cable or television card configured to receive television programming.
