Abstract
Abstract A terminal for use in a multi-point video conference system that includes a plurality of terminals connected to each other via a network, the terminal includes a compressor for packetizing video data inputted from a video camera, and outputting packetized data to the network. A decompressor receives a plurality of packets transmitted from other terminals via the network in a time sharing manner, and decompresses the received packets in an order of reception. The decompressor outputs decompressed video information. A plurality of storage elements store the decompressed video information in a frame unit. The contents stored in the storage elements are displayed on a display. A switch changes over the contents of the storage elements to supply the display.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
78 words
A television broadcasting method comprising: compressing and multiplexing signals from a plurality of channels over a single carrier frequency; transmitting the multiplexed signals; receiving the multiplexed signals; demultiplexing the received signals and separating the received signals into time-sequential channel-discrete packets; storing said time-sequential channel-discrete packets for a predetermined period of time; selecting a desired channel; decompressing and reconstructing those packets discrete to the selected channel; and displaying the reconstructed signals of the selected channel on a real-time basis.
Claim 2
Dependent Claim
78 words
