Abstract
An apparatus includes an input circuit, a storage device, a retrieve circuit, a decrypt circuit, and an output circuit. The input circuit is configured to receive packets of encrypted encoded video data from a first network. The storage device is preauthorized by the first network to store the encrypted encoded video data. The retrieve circuit is configured to retrieve the encrypted encoded video data from the storage device for decryption. The decrypt circuit is configured to decrypt the encrypted encoded video data without further authorization. The output circuit is configured to transmit a signal representing the encrypted encoded video data while the retrieve circuit retrieves the encrypted encoded video data from the storage device.
