Abstract:
A video and audio signal editing and transmitting apparatus comprising:a compilation unit which has a first storage means having a storage capacity in a range of several weeks to several months, receives video signals serving as video stock and audio signals corresponding to the video signals, which has an encoder that compresses and encodes the received video and audio signals and multiplexed packets of the compressed and encoded video and audio signals and code data in the form of code data packets, and which has a record controller that performs predetermined editing on the compressed and encoded video and audio signals and code data from the encoder to obtain a signal storage format for staggered playback of multiple channels, stores the edited results in the signal storage format in the first storage means, and transmits the compressed and encoded video and audio signals stored in the first storage means in accordance with a first transmission request;a play-out unit which has a second storage means having a capacity in a range of several days to several weeks and third storage means constituting an on-line storage for temporarily storing the compressed and encoded video and audio signals and having a substantially smaller storage capacity than the storage capacity of the second storage means, receives the compressed and encoded video and audio signals transmitted from the compilation unit, initially stores the compressed and encoded video and audio signals received by the play-out unit in the second storage means, routes the compressed and encoded video and audio signals from the second storage means to the third storage means, reads and reproduces the compressed and encoded video and audio signals from the second storage means for feeding to the third storage means in accordance with a second transmission request, and which has code data insertion circuits for inserting the code data packets from the record controller into the reproduced compressed and encoded video and audio signals prior to transmission, and transmits the reproduced compressed and encoded video and audio signals from the third storage means; anda transmission unit which transmits the reproduced compressed and encoded video and audio signals transmitted from the play-out unit to subscribers according to a broadcast program.
