KPIC will cease analog transimission on Channel 4 on June 12, 2009 and only broadcast in digital on channel 19. The KPIC digital signal may not be available in all the same areas as the analog signal. For specific information about your geographic location, click here for the FCC digital signal mapping tool.

The transmission and reception of Digital TV significantly enhances visual resolution, color, noise reduction and supports high fidelity multi-channel audio reproduction. There are several digital formats, ranging from converted analog material having a 4:3 aspect ratio (width / height of the picture), to a wide screen 16:9 aspect ratio. The 4:3 digital signal utilizes some 300,000 individual pixels to construct an image. The 16:9 digital signal has two formats. The first, constructs the image with 720 horizontal lines and 920,000 pixels. The second constructs the image with 1080 horizontal lines and 2,073,000 pixels. The higher number of pixels yields higher visual resolution.

KPIC is now simultaneously broadcasting it’s daily programming digitally. Transmissions have an aspect ratio of 4:3, and facilitate the enhancements described above.

To view KPIC-DT, reception of UHF channel 19 is required, which in some instances will require the use of an outdoor antenna. The latter may be any commercially available type. A critical aspect of the installation is that the antenna is aimed at our transmitter on Rose Mt. in Roseburg. Also, the connecting cable from antenna to TV must be in good condition Digital transmission is very different from analog. If a viewer has a consistent picture, it should be digitally correct. There is no visible ghosting or noise, such as may have been seen with a marginal analog signal. However, if the received digital signal is of inadequate strength, reception may vary from perfect to none. This is called the digital "cliff effect" and may be helped with careful attention to the receiving antenna and cable connected to the TV. It is not recommended that splitters be installed unless they are of professional quality, and there is adequate signal received in order to accommodate the 50% loss incurred in splitting the signal.
