Final answer:
In UDP-based Internet television transmission, if part of the transmission is lost, it results in temporary video or audio glitches due to lack of packet delivery guarantees in UDP.
Step-by-step explanation:
When part of the transmission is not delivered to the destination in an Internet television transmission using UDP (User Datagram Protocol), the missing data typically results in a temporary loss of quality in the video or audio stream. This might appear as a brief glitch, pixelation, or skipped frames in the case of video, or a momentary drop in audio. Unlike TCP (Transmission Control Protocol), UDP does not guarantee the delivery of packets, nor does it ensure they are received in the correct order. This is acceptable for live streaming services where real-time transmission is more crucial than perfect data integrity. Video streaming services often use UDP because it allows for faster transmission speeds, which is essential for maintaining a smooth viewing experience.
