Abstract
The present disclosure provides a system that can receive a group of channels (at least one of which includes an I-frame) from a DSL network, a memory that can store the I-frames, and a channel change detector that can detect a user's selection of a particular channel. If the memory contains the I-frame corresponding to the particular channel and if an I-frame has not been received from the DSL network, then the system provides the stored I-frame from the memory to the user.
