1. A removable transcoding device configured to be inserted into a television receiver that is operated by a television viewer, the removable transcoding device comprising:

  • a host interface configured to be directly inserted into the host device to thereby physically and electrically couple the removable transcoding device to the television receiver and to facilitate electronic communication between the removable transcoding device and the television receiver; and

    a processor disposed within the removable transcoding device, wherein the processor is configured to receive a first encrypted stream from the television receiver that is physically coupled to the removable transcoding device via the host interface, wherein the first encrypted stream comprises a media stream in a first format, and wherein the processor is further configured to decrypt the first encrypted stream, to transcode the media stream from the first format to a second format different from the first format that is routable on a communications network, to encrypt the transcoded media stream in the second format to generate a second encrypted stream, and to provide the second encrypted stream to the television receiver via the host interface to thereby allow the television receiver to securely forward the second encrypted stream over the communication network to a remote device, wherein the remote device is operated by the same television viewer that operates the television receiver, and wherein the second encrypted stream is transmitted to the remote device via the communication network without the television receiver decrypting the second encrypted stream, and wherein the processor is further configured to receive an instruction from the remote device via the host interface, and to direct the television receiver to adapt the first encrypted stream in response to the instruction received from the remote device;

    wherein the processor establishes a first secure session with the television receiver and a second secure session with the remote device, and wherein the first secure session transports the first encrypted media stream from the television receiver to the removable transcoding device and control instructions from the removable transcoding device to the television receiver via the host interface, and wherein the second secure session transports the instruction from the remote device to the removable transcoding device and the second encrypted stream from the removable transcoding device to the remote device, and wherein the processor is further configured to establish a first key with the television receiver for the first secure session and to establish a second key with the remote device for the second secure session.
