ABSTRACT:
Digital video data (such as full motion video and audio) is distributed over a computer network to workstations by an analog video server. The network carries digital network signal traffic. The analog video server retrieves video data from a storage device. The analog video server then decompresses the digital data and converts it into an analog signal. The analog signal is shifted to a bandwidth (such as television channels) that is different from the bandwidth of the network signal traffic, and then combined with the network signal traffic to be distributed over the network. At a workstation, the analog signal is split off of the network signal traffic and provided to a display. Plural workstations can display the same analog signal. Schedules for broadcast times are provided on the network to the workstations. Plural channels in the analog signal bandwidth can be utilized to simultaneously broadcast plural analog signals to the workstations.
