Cable Television Operators (CTO) receives broadcast signals that are transmitted over the air under the Advanced Television System Committee (ATSC) standard in the form of 8VSB signals in digital format. The CTO converts, encrypts, and compresses the signals to either analog or QAM, IP, or other digital signal standards (QAM*), and transmits these signals through the cable plant or streaming video services to their customers. The QAM* signals lose video quality when they are encrypted and compressed to be sent through the cable plant or streamed. The local channels are broadcasted as digital off-air signals and are intercepted in the form of 8VSB signals. These 8VSB signals are converted into clear QAM* signal shown in FIG. 1. The clear QAM* signals have a higher video quality due to no encryption and compression. The clear and encrypted QAM* signals are combined and inserted into the video providers equipment (DVR, etc.) at the customer's premises shown in FIG. 2. Customers are allowed to use existing interface and channel guide with the subscribed network in addition to the off-air digital signals.
