Période

September, 2011

Canada

The donor and her sisters purchased this converter for their mother on August 30, 2011. The donor’s mother found that the picture on screen would fairly often become digitized (large pixels; garbled, partially blackened, jumpy and/or frozen image) and that she had to frequently adjust the “rabbit ears” on top of her television set to obtain a better picture. This is more symptomatic of issues with the antenna’s age, size, and/or gain more than it is indicative of any quality or functionality issues with the converter. Nonetheless, this constant adjustment proved to be very difficult for the owner, who is in her eighties. After using this product for a week, she abandoned it in favour of digital cable service from Rogers. The object was donated to the Museum shortly after. (From Acquisition Worksheet, in Supp. Info.)

Fonction

This object is used in order to convert incoming digital television signals into analogue signals so that they may be received by analogue television receivers. It also prepares the signal to be compatible in terms of frame rates and resolution. (From Acquisition Worksheet, in Supp. Info.)

Technique

Since 2005, various countries worldwide have been gradually making a transition away from broadcasting analogue television signals. A transition to digital signals will allow the vacated frequency spectra formerly used by analog transmission to be reused for other communications purposes. Canada’s transition was completed by August 31, 2011. The CBC is permitted to use some analogue signals until August 31, 2012, when the Canadian transition will be officially complete. A converter such as this one enables incoming digital broadcast signals to be displayed on existing analogue receivers. It not only converts the signal from digital to analogue, but also alters the resolution and frame rates so that they are compatible for display on analogue television sets.
