after detecting that the client-side computing device is paired to the viewing device, detecting, by the client-side computing device, that the client-side computing device has been unpaired from the viewing device; and in response to detecting that the client-side computing device has been unpaired from the viewing device, executing a remedial action. ## Claims ### Claim 1 A method comprising: detecting, by a client-side digital content delivery device, that a client-side computing device has been unpaired from an authorized viewing device that is separate from the client-side digital content delivery device, wherein the client-side computing device has been paired to the authorized viewing device, via a communication interface between the client-side computing device and the authorized viewing device to cause digital content received from a remote server to be presented on the authorized viewing device; and in response to detecting that the client-side computing device has been unpaired from the authorized viewing device, executing a remedial action; wherein the communication interface is configured to receive a unique identifier associated with the authorized viewing device. ### Claim 2 (depends on 1) The method of claim 1, wherein detecting that the client-side computing device has been unpaired from the authorized viewing device comprises detecting removal of a wired connection between the client-side computing device and the authorized viewing device. ### Claim 3 (depends on 1) The method of claim 1, wherein detecting that the client-side computing device has been unpaired from the authorized viewing device comprises detecting loss of a wireless connection between the client-side computing device and the authorized viewing device. ### Claim 4 (depends on 1) The method of claim 1, wherein the remedial action comprises disabling presentation of the digital content on the client-side computing device. ### Claim 5 (depends on 1) The method of claim 1, comprising determining that the device identifier received from the authorized viewing device matches a recorded device identifier. ### Claim 6 A client-side digital content delivery device comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the client-side digital content delivery device to perform operations including, at least: detecting, by a client-side digital content delivery device, that a client-side computing device has been unpaired from an authorized viewing device that is separate from the client-side digital content delivery device, wherein the client-side computing device has been paired to the authorized viewing device, via a communication interface between the client-side computing device and the authorized viewing device to cause digital content received from a remote server to be presented on the authorized viewing device; and in response to detecting that the client-side computing device has been unpaired from the authorized viewing device, executing a remedial action; wherein the communication interface is configured to receive a unique identifier associated with the authorized viewing device. ### Claim 7 (depends on 6) The client-side digital content delivery device of claim 6, wherein detecting that the client-side computing device has been unpaired from the authorized viewing device comprises detecting removal of a wired connection between the client-side computing device and the authorized viewing device. ### Claim 8 (depends on 6) The client-side digital content delivery device of claim 6, wherein detecting that the client-side computing device has been unpaired from the authorized viewing device comprises detecting loss of a wireless connection between the client-side computing device and the authorized viewing device. ### Claim 9 (depends on 6) The client-side digital content delivery device of claim 6, wherein the remedial action comprises disabling presentation of the digital content on the client-side computing device. ### Claim 10 (depends on 6) The client-side digital content delivery device of claim 6, wherein the memory stores instructions that, when executed by the one or more processors, cause the client-side digital content delivery device to perform operations including determining that the device identifier received from the authorized viewing device matches a recorded device identifier. ### Claim 11 A non-transitory computer-readable medium storing instructions that, when executed by one or more computer processors of a client-side digital content delivery device, cause the client-side digital content delivery device to perform operations comprising, at least: detecting, by a client-side digital content delivery device, that a client-side computing device has been unpaired from an authorized viewing device that is separate from the client-side digital content delivery device, wherein the client-side computing device has been paired to the authorized viewing device, via a communication interface between the client-side computing device and the authorized viewing device to cause digital content received from a remote server to be presented on the authorized viewing device; and in response to detecting that the client-side computing device has been unpaired from the authorized viewing device, executing a remedial action; wherein the communication interface is configured to receive a unique identifier associated with the authorized viewing device. ### Claim 12 (depends on 11) The non-transitory computer-readable medium of claim 11, wherein detecting that the client-side computing device has been unpaired from the authorized viewing device comprises detecting removal of a wired connection between the client-side computing device and the authorized viewing device. ### Claim 13 (depends on 11) The non-transitory computer-readable medium of claim 11, wherein detecting that the client-side computing device has been unpaired from the authorized viewing device comprises detecting loss of a wireless connection between the client-side computing device and the authorized viewing device. ### Claim 14 (depends on 11) The non-transitory computer-readable medium of claim 11, wherein the remedial action comprises disabling presentation of the digital content on the client-side computing device. ### Claim 15 (depends on 11) The non-transitory computer-readable medium of claim 11, wherein the non-transitory computer-readable medium stores instructions that, when executed by one or more computer processors of a client-side digital content delivery device, cause the client-side digital content delivery device to perform operations comprising determining that the device identifier received from the authorized viewing device matches a recorded device identifier.
