Problems solved by technology

However, general computer systems are usually not easy to carry because of their large size. Even notebook computers still have considerable volume and weight. Therefore, users often give up when they need to burn DV videos because they do not have a computer system at hand.
In addition, DV cassettes are not as thin and light as DVD discs. Carrying too many DV cassettes is a burden in terms of space and weight.
This situation will cause great trouble to those who travel long distances or those who do not have a computer system

Embodiment Construction

[0028] The present invention describes a portable audio-visual data burning control device, and the preferred embodiments are described as follows.

[0029] Please refer to FIG. 1 , which shows a schematic diagram of a portable audio-visual data burning control device according to a preferred embodiment of the present invention. The portable audio-visual data recording control device 20 can directly control the external recorder 30 to record audio-visual data in the camcoder 10 in real time without using a computer system. The recording control device 20 includes a first I / O interface 202 , a control unit 204 , an audio / video encoding unit (encoder) 206 and a second I / O interface 208 . The first I / O interface 202 and the second I / O interface 208 are, for example, an IEEE1394 interface or a USB interface, which can support the transmission of large amounts of data.

[0030] The control unit 204 can read the video and audio data recorded by the camcorder 10 through the first I / ...

Abstract

The portable audio-video data burning controller for controlling burning machine includes the first I / O interface, control unit, audio-video coding unit and the second I / O interface. The control unit reads the audio-video data of video camera from the first I / O interface; the audio-video coding unit encodes the read audio-video data into coded data; and the second I / O interface transmits the coded data to the burning machine so as to store the coded data in the optical memory medium.

Description

technical field [0001] The present invention relates to a portable audio-visual data recording control device, and in particular to a recording control device for quickly transcoding DV movies. Background technique [0002] With the advancement of technology, the audio-visual data specifications of camcorders have developed from the early Beta and VHS specifications to the current household (Consumer) digital VCR specifications, that is, DV (Digital Video Camcorders) specifications. And so far, the DV specification for home video recorders has been roughly determined to become the mainstream specification. [0003] Generally known as DV, also known as mini-DV for household use, using 1 / 4 inch (6.35mm) metal evaporation tape. As far as the DV cassette (Cassette) is concerned, DV uses a 10 micron (μm) magnetic track pitch in the standard mode (Standard Playbackmode, SP), and a cassette can record 60 minutes. In the growth mode (Long Playback mode, LP) adopts 6.7 micron magne...
