1. A method of frame thinning by a data processing device coupled to a network, comprising: receiving a message through the network, said message indicating a need to thin streaming media data being sent through the network; assigning a plurality of frame types to the streaming media data, the frame types including at least one known frame type; evaluating priority of streaming media data based on frame type; and sending only selected streaming media data, wherein the message is received at a caching proxy server that sends the selected streaming media data to a client device, the method further comprising performing the following at the caching proxy server: prior to receiving the message, determining based on a data receiving rate or a data processing rate of the client device, that the client device requires frame thinning; checking whether an originating server from which the streaming media data is sent to the caching proxy server supports all frame types required for frame thinning; and responsive to receiving the message, and conditional upon determining that the originating server supports all frame types required for frame thinning, thinning the streaming media data to generate the selected streaming media data.
