Abstract
Abstract Video information records are recorded in a small capacity memory included in a tape cassette under the control of a system controller supplied with date information from a calendar circuit, clock information from a clock circuit, place information from a GPS (global positioning system) circuit, and scene setting information from a scene setting switch of an operation unit (such as a video camera). When video information is recorded by using the date information, for example, the system controller uses that date information as well as date information previously stored in the memory to process the just-recorded video information record.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
144 words
A video information recording method for recording video information packets each having its contents composed of at least a recording starting track number, a recording ending track number and event information, comprising the steps of: comparing said event information contained in two previously recorded video information packets prior to recording a newly supplied video information packet; combining said two previously recorded video information packets into a common packet if the compared event information differs by less than a predetermined amount; replacing the contents of a first of said two previously recorded video information packets with the contents of said common packet; and recording the contents of said newly supplied video information packet in place of the contents of a second of said two previously recorded video information packets if it is determined that the compared event information differs by less than the predetermined amount.
