NO.
For a SD NTSC Analog TV - yes you do.
If the DVR has a tuner, you might have to switch it to antenna from cable. If it has no tuner you might need a converter box.

An "SD card" is a Secure Digital memory card.
For most people, their old antenna will work just fine. Don't let the people at the electronics store fool you, there is no such thing as an "HD antenna." There is nothing special that needs to be done to an antenna to receive HD signals. In fact, many of the antennas that are being marketed as "HD antennas" are inferior UHF-only antennas that receive a smaller set of signals than your old antenna. However, some people who were barely receiving an analog signal may need to buy a better antenna. Also, if the location of the digital transmitter has changed or the signal strength of the TV station has changed, you may need to re-aim or replace your old antenna. Simply plug the old antenna into the converter box and then plug the converter box into your old TV where the antenna used to go and you will be fine. The converter box will tune in a digital station (some digital stations are HD, some are not) and convert the digital signal into an old-fashioned analog standard definition signal and feed it into your old analog TV. You will not be able to watch shows in HD on your old analog TV, but you will be able to watch a version of the HD broadcast that has been converted into Standard Definition (SD) for you. You will be able to watch all of the digital stations including the HD ones but you will see them in Standard Definition. Standard Definition is 480i. Digital to Analog converter boxes receive all tv transmissions of 1080P , 1080i , 720P , 480P , 480i and coverts them ALL to 480i to watch on a standard definition NTSC Analog TV.
A CF to SD converter is a small device that allows data to be transferred between CompactFlash (CF) and Secure Digital (SD) memory cards. It works by physically adapting the connection interface of the CF card to fit into the slot of an SD card reader or device. This enables the data stored on the CF card to be read and transferred using the SD card reader or device, making it easier to access and manage data across different types of memory cards.
Yes. Digital signal are sent to the cable or satellite box and then converted to a usable signal for you TV RF, or vidio via RCA jacks. The SD stands for STANDARD DEF> NOT HIGH DEF. so your picture is still good digital but not HIGH Def.
Secure Digital
SD
To transfer data between different types of memory cards using an SD to CF converter, simply insert the SD card into the converter and then insert the converter into the CF card slot on your device. The data can then be transferred between the two memory cards as needed.
SD stands for secure digital, one type of memory card. SDA stands for Secure Digital Association, a standards cooperative.
