Digital Transition - Scenario Details
The
big question that remains is:
How does your systems fit into this
transition?
Unsure? Below, each
scenario is broken down with an explanation and application. Pick the one that
best fits your situation and click on the title. You will be taken to a page
with a more detailed explanation as well as the specific equipment needed to
implement your unique transitional requirements:
| For Scenario 1: Are you simulcasting digital and analog? See Scenario 8 | |
| Scenario 2: | |
| Explanation: | This system will allow you to receive the local, digital off-air broadcast programming that is available in the market and distribute it through the facility in a format that can be viewed by the existing analog televisions. (See Scenario 10 for conversion to analog at the television) |
| Application: | All of the televisions in the system have analog tuners and cannot receive the digital channel directly. |
| For Scenario 2: Are you simulcasting digital and analog? See Scenario 8 and Scenario 9 | |
| Scenario 3: | |
| Explanation: | This system will allow you to select a few desired digital channels from the local Cable Television Company and distribute it through the facility in a format that can be viewed by the existing analog televisions, |
| Application: | This application assumes that all the TV’s in the system are analog and therefore cannot receive the digital channel directly. |
| Scenario 5: |
Digital Off-Air (8VSB) Reception - Digital CATV (QAM) Viewing |
| Explanation: | It is common for digital televisions to only lock to digital (CATV) signals when the digital television is set or tuned to the “CATV” mode. This creates difficulties for systems/facilities transmitting standard ATSC digital off-air or broadcast 8VSB signals. This solution solves this problem by converting an entire digital off-air channel to a digital (CATV) signal. |
| Application: | This eliminates the problem of having to reprogram the television every time the customer wants to switch between digital CATV and digital off-air channels. |
| For Scenario 5: Are you simulcasting digital and analog? See Scenario 9 | |
| Scenario 6: | |
| Explanation: | The system will allow you to select a few desired digital channels from the local Cable Television Company, and ignore the undesired channels. This system is the digital version of a traditional ‘Cherry Picker’ system. |
| Application: | This is extremely valuable if a large facility only has a 450 MHz distribution network, and the MSO’s digital offering starts at 650 MHz, there is no room for the digital tier without a costly network upgrade. A transcoder can receive the desired high frequency QAM channels and transcode them to available channels within the existing 450 MHz network, delivering the desired CATV QAM channels, while preventing a costly network upgrade. |

| Scenario 8: |
Digital Off-Air (8VSB) Reception - Simulcast Digital Off-Air (8VSB) and Analog Viewing |
| Explanation: | This system is designed as an example of how to deploy Scenario 1 and Scenario 2 to support both analog and digital viewing locations. See the individual solutions for their detailed descriptions and explanations. |
| Application: | The two solutions that we are referring to are Digital Off-Air Reception - Digital Viewing and Digital Off-Air Reception - Analog Viewing. |
| Scenario 9: |
Digital Off-Air (8VSB) Reception - Simulcast Digital CATV (QAM) and Analog Viewing |
| Explanation: | This system is designed as an example of how to deploy Scenario 2 and Scenario 5 to support both analog and digital viewing locations. See the individual solutions for their detailed descriptions and explanations. |
| Application: | The two solutions that we are referring to are Digital Off-Air Reception - Analog Viewing and Digital Off-Air Reception - Digital Viewing (QAM). |
| Scenario 10 | |
| Explanation: | This system will allow you to receive the local, digital off-air (8VSB) broadcast programming that is available in the market and convert it to analog at the television. (See Scenario 2 for conversion to analog at the headend) |
| Application: | All of the televisions in the home
have analog tuners and cannot receive the digital channel directly. |
