What is the consequence of a high BER for video?

• A. A delayed transmission of sound
• B. A clear video feed
• C. Picture fails
• D. Improved visual quality

Answer: (C)

A high Bit Error Rate (BER) in video transmission indicates that many bits of data are being incorrectly transmitted. When the error rate is high, it leads to a loss of data integrity, which is crucial for delivering a clear and coherent video signal. Consequently, this often results in broken images, blockiness, or complete failure of the picture—a phenomenon often referred to as pixelation or freezing. In video transmissions, a clear and continuous stream of data is essential for creating an enjoyable viewing experience. Therefore, a significant presence of errors can manifest in severe visual disruptions, making the video feed unwatchable. This directly ties into why a high BER will cause problems for video playback, leading to the result of picture failure. The other options portray outcomes that would not arise from a high BER. For instance, delayed sound or improved visual quality would require a stable signal, which is not achievable under high error rates.
