Claims
- 1. A video storage and communication device used for a video information communication system to distribute video data to a terminal set connected with a communication channel, the communication device comprising:a first video storage portion for storing a first coded video data; a video generating portion for generating a second coded video data different from the first coded video data by re-encoding the first coded video data; a second video storage portion for storing the second coded video data generated by the video-generating portion, wherein said first and second video storage portions are separate and distinct from one another; a video-reproduction control portion for selecting the first coded video data stored in the first video storage portion or the second coded video data stored in the second video storage portion; and a transmitting portion for transmitting the first coded video data or the second coded video data selected by the video-reproduction control portion over the communication channel, wherein the first coded data and the second coded data are separate from and independent of one another.
- 2. A video storage and communication device according to claim 1, wherein the video-generating portion generates the second coded video data having a reduced number of video frames as compared with the first coded video data.
- 3. A video storage and communication device according to claim 2, wherein the video-generating portion includes a video restoring portion for decoding the first coded video data and a re-encoding portion for only intraframely encoding the video-data decoded by the video restoring portion.
- 4. A video storage and communication device according to claim 2, wherein the video-generating portion includes a video restoring portion for decoding the first coded video data and a re-encoding portion for interframely encoding the video-data decoded by the video restoring portion.
- 5. A video storage and communication device according to claim 2, wherein the video-generating portion includes a video restoring portion for decoding the first coded video data and a re-encoding portion for still picture encoding the video-data decoded by the video restoring portion.
- 6. A video storage and communication device used for a video information communication system to distribute video data to a terminal set connected with a communication channel, the communication device comprising:a receiving portion for receiving a coded video data over the communication channel; a video generating portion for generating a coded video data to be stored by re-encoding the received coded video data replacing frames of the received coded video data with a corresponding re-encoded frame at an arbitrary interval; a video storage portion for storing the coded video data generated by the video generating portion; a video-reproduction control portion for reading the coded video data from the video storage portion; and a transmitting portion for transmitting the coded video data read out by the video-reproduction control portion over the communication channel.
- 7. A video storage and communication device according to claim 6, wherein the video generating portion includes a restoring portion for decoding the coded video data and re-encoding portion for only intraframely encoding the video-data decoded by the restoring portion.
- 8. A video storage and communication device according to claim 6, wherein the video generating portion includes a restoring portion for decoding the coded video data and a re-encoding portion for still picture encoding the video-data decoded by the restoring portion.
