1. An apparatus that provides an output stream to a display device over a network comprising a radio frequency (RF) transmission channel, the apparatus comprising:

  • an input configured to receive video information comprising television programming from a program source, wherein the video information is selected responsive to control information received from the display device via the network that identifies the selected video information based upon an input received from a viewer at the display device;

    a processing unit configured to encode the selected video information to create a processed stream as the selected video information is received, wherein the processed stream comprises video frames of the selected video information that are encoded for transmission on a plurality of subbands of the RF transmission channel each representing a different resolution of the video frame and each having an error resiliency, and wherein the processing unit is further configured to receive network feedback information comprising information about a characteristic of the RF transmission channel, and to adapt the error resiliencies for the plurality of subbands as the selected video information is received based on the characteristic of the RF transmission channel described in the network feedback information so that the subband representing the lowest resolution of the video frame is more error resilient and higher quality than the subband representing the highest resolution of the video information frame;

    a communications unit configured to manipulate the processed stream to produce an output stream; and

    a wireless transmitter configured to transmit the output stream to the display device via the network.
