1. Field of the Invention
The present invention relates to a video data transmitting apparatus and a video data receiving apparatus used for the transmission of compressed and encoded video data and to a video data transmitting and receiving system using the same.
2. Description of the Related Art
In a video signal transmitting and receiving system for conveying a video signal from a news site to a broadcasting station via a satellite communication line, for example, the video signal is subjected to analog frequency modulation and transmitted at the signal speed, that is, the real time speed, of the video signal at the time of filming as is.
Since the video signal transmitting apparatus and the video signal receiving apparatus do not allow a video recorded using a single-unit video camera-recorder, that is, a camcorder, etc. at the news site to be transmitted at a higher speed, it is often not possible to secure sufficient time for editing the video before broadcasting.
Some apparatuses are therefore designed to transmit the video signal at a higher speed. However, this is costly and it is not always necessary to transmit the signal at a higher speed to allow editing, such as when covering a live sports event.
