Definitions
- the buffer memory 9 is a memory for recording a list of video contents recorded on the video tape 8, and this memory is provided in a cassette that stores the video tape 8.
- the list information in the buffer memory 9 is read / written by the memory read / write rotation 10 and is transmitted / received to / from another device connected to the network 11 via the LAN interface 6.
- FIG. 6 is a conceptual diagram showing the relationship between the network transfer speed during recording, the buffer usage rate, and the tape speed.
- Faster network transfer rates result in faster buffer utilization.
- the signal is recorded by running the video tape. This reduces buffer usage.
- the video tape drops to a certain value, the running of the video tape is stopped, and the running of the video tape is stopped for a certain distance in the opposite direction in preparation for the next recording. The reason why the vehicle travels a certain distance in the reverse direction is to take into account the distance traveled without recording until the vehicle reaches a stable speed.
- the buffer usage rate reaches a certain value, the video tape is run again to achieve a stable speed and then recording is resumed.
- data is recorded while automatically adjusting the running speed of the video tape in accordance with the transmission speed of the network without using an external storage device such as a hard disk device. be able to.
