Embodiment Construction

[0017] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Referring first to FIG. 1, an operation example of the virtual editing function will be described. In FIG. 1, a video recording / reproducing device 11 has a virtual editing function. The recording / reproducing device 11 has a recording medium, such as a memory device and a hard disk device, which secures areas therein for recording the material storage unit 12 and the material information storage unit 13 . Here, it is assumed that the recording / reproducing device 11 handles MPEG 2 long-GOP data (GOP: 15 frames) as a recording material.

[0019] When an original recording video material (hereinafter referred to as original material: material name ORG 0001) is being input in the material recording, the recording / reproducing device 11 stores the original material in the material storage unit 12, reads out the original material The material informatio...

Abstract

The present invention relates to a method, a sending side device and a receiving side device for transmitting video material. When the sender device (A) receives the transmission instruction for editing material, it reads the editing information from the material information storage unit (A13) according to the name of the editing material instructed to be transmitted and captures the time positions of the start frame and the end frame. At this moment, the device (A) reads the original material from the recording material storage unit (A12), determines that the GOP including the cutting start frame is used as the head GOP and the GOP including the cutting end frame is used as the tail GOP, so as to cut out the GOP that includes both Editorial material of the GOP. The device (A) converts the start frame of edit information into the number of frames from the head of the head GOP, and the end frame into the number of frames from the head of the tail GOP to store the numbers. The device (A) transmits the editing material thus created to the receiving side device (B) in the MPEG 2 long-GOP data format together with the editing information.

Description

technical field [0001] The present invention relates to a method for transmitting video material, a sending-side device for transmitting said video material and a receiving-side device for transmitting said video material, so that video reception on the receiving side The / reproducing device can reproduce a video virtual editing result obtained by reproducing only a part of video material via the video recording / reproducing device on the transmission side using the editing information. Background technique [0002] In general, in video information processing apparatuses, a "virtual editing function" that reproduces only a part of an originally recorded video material (referred to herein as a recording material) by using work information in editing (referred to herein as edit information) in advance has been widely used. . When both the video recording / reproducing device on the sending side and the video recording / reproducing device on the receiving side use the video compre...
