receiving a request from a first one of the plurality of receiver devices for information associated with television programming guide data that is needed by the first receiver device to assemble a complete television programming guide;

unicasting the information to the first receiver device,

wherein the encoding television programming guide data comprises:

encoding programming schedule information comprising a first portion of a television programming guide for transmission over at least first and second ones of the channels, and

encoding information comprising a second portion of the television programming guide, other than the first portion of the television programming guide and other than the programming schedule information, for transmission over at least one channel other than the first and second channels,

wherein the encoding data further 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 the television programming guide; and

transmitting the second portion of the television programming guide at a slower rate than the programming schedule information, wherein the second portion of the television programming guide comprises channel logo information.

9. The method of claim 8 , wherein the dividing the encoded television programming guide data comprises dividing the encoded data over at least four channels.

10. The method of claim 8 , wherein the method is implemented as computer-executable instructions embodied on a computer-readable memory device.

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 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,

wherein the encoding data comprises:

encoding programming schedule information for transmission over at least first and second ones of the channels, and

encoding information other than programming schedule information for transmission over at least one channel other than the first and second channels,

wherein the encoding information other than programming schedule information for transmission over at least one channel other than the first and second channels comprises encoding television station logo information.

12. 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 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,

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, and

wherein the information other than programming 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.

13. 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 program guide data for multicast transmission, and

divide the encoded program guide data into data blocks for transmission over a plurality of channels, wherein when encoding, the first logic is further configured to:

include a sequence number in a header of each data block, the sequence number identifying a relative location of each of the data blocks within a programming guide; and

a first communication interface configured to:

multicast the encoded data over the plurality of channels, and

retransmit the multicasting at predetermined intervals; and
