Do OTA decryption receivers require internet?

We study one of the most difficult variants of the problem when the receivers are state- less. Namely, each user is given a fixed set of keys which cannot be updated through the · lifetime of the system. In particular, they do not change when other users join or leave · the system, or evolve based on the history of past transmissions. Instead, each transmis- sion must be decrypted solely on the base of the fixed initial configuration of each user’s

Takes about 20 minutes to setup for your zip code, then less than 5 minutes nightly to keep the next 2 weeks of program information up to date. Doesn't require a continuous internet connection...will try to update nightly (built-in WiFi) but you can simply force a manual connection every week ...

Another method of pirate decryption that has become popular recently is known as Internet Key Sharing (IKS). This is accomplished by an Ethernet cable hooked to the receiver that allows updated decryption keys to be fed to the unit directly from the internet.

The OTAT feature permits a key to be extracted from an OTAT-capable cryptographic system using a fill device, such as the KYK-13 or KYX-15/KYX-15A and then loaded ("squirted") into another cryptographic system as needed. Alternatively, encryption systems may also be configured to automatically receive ...

ChannelMaster does have a cheaper alternative to a used DVR+, the CM-7004, it has a single tuner, records to a USB stick, is easy to operate, and does not require an Internet service for guide data.

Guide data. A program guide from Gracenote or Zap2it feeds the DVR episode titles, cast info, and schedules 14 days out. Most OTA DVRs need an internet connection for the guide.

And many devices that are authorized to decrypt ATSC 3.0 still need an Internet connection to do so. SiliconDust, the company behind the HDHomeRun network tuners, raised this issue in a filing with the FCC.

The issue surfaced after a filing highlighted that some boxes need an internet connection to decrypt over-the-air signals. If the internet connection is down, those devices may not receive emergency alerts carried on encrypted broadcasts.

One of the reasons for this thread is that these same OTA broadcasters who provide their content unencrypted over the ATSA 1.0 signal, are transmitting the same content over the ATSC 3.0 signal in an encrypted format that none of the current gateway devices can decrypt.
