[0050] Next, a description will be given of a hybrid type recorder which is an embodiment of the recording apparatus according to the present invention, which can perform dual functions as a DVD recorder and an HD recorder.

[0051] The hybrid type recorder of this embodiment includes an HD, and can temporarily store a plurality of contents in the HD. Among the temporarily stored contents, the contents worthy of permanent storage can be selectively recorded on DVD. Now explaining its structure, the audiovisual content includes at least one VOB (Video Object) and management information on the VOB or VOBs. A VOB is a program stream obtained by alternately multiplexing a video stream and an audio stream. As described above, each VOB includes management information. However, describing the processing of management information would make the description too complicated. Therefore, in the following description, for the sake of brevity, management information will not be considere...

Embodiment 2

[0096] Embodiment 2 concerns selection of content to be re-encoded. As described above, re-encoding is a series of processes of decoding one content and then encoding the decoded content again, which requires actual reproduction time. The actual reproduction time refers to the time it takes to actually reproduce the content. That is, when it takes one hour to reproduce the content, it takes one hour to re-encode the content stored in HD and then record it to DVD. Since this is a very time-consuming process, recoding is not an easy option. In consideration of the above, the present embodiment performs scheduling so that the order of contents to be backed up can be determined in such a way as to minimize the time required for re-encoding. The order is determined according to the priority assigned to each content, ie, first priority, second priority, and third priority. This first priority is assigned to the content with the highest priority, so that the content can be recorde...

Embodiment 3

[0131] According to the backup processing of Embodiments 1 and 2, several contents are written into a DVD until the DVD is full. However, if several contents are written until the DVD is full, other contents cannot be written to the DVD. That is, there is no remaining space available in the DVD to record content that is scheduled to be broadcast in the future. In consideration of the above-mentioned problems, this embodiment allows the user to reserve free space in the DVD before executing the processing of Embodiments 1 and 2.

[0132] The user designates a free space to be reserved using the free space reserve menu shown in FIG. 13 . Fig. 13 shows an example of the free space reserve menu. The free space reserve menu includes: buttons bn1 and bn2, used to select whether to utilize the byte size or recording time to specify the space to be reserved; column nm1, used to input the numerical value of the specified byte size; column nm2, used to input A numerical value in minu...

Abstract

Disclosed is a recording apparatus for recording a plurality of audio-visual contents stored in a HD to a writable DVD. A drive controller copies at least one of the contents stored in the HD to the DVD. If the available capacity of the DVD left after the copying falls short to copy a remaining content, the remaining content is re-encoded prior to being recorded in the DVD. The bit rate to be allocated to the remaining content upon re-encoding is calculated from the available capacity of the DVD and the reproduction time of the remaining content to be re-encoded.

Description

technical field [0001] The present invention relates to a recording device, a recording program and a recording method, the recording device being, for example, a hybrid recorder which executes, for example, a DVD recorder for DVD (Digital Versatile Disc) and an HD for HD (Hard Disk) Dual function of logger. In particular, the present invention relates to a technical improvement for backing up content recorded in one recording medium in another recording medium. Background technique [0002] Manufacturers of DVD recorders and HD recorders are now vying to develop a better product to take over the home VCR replacement market. Both DVD and HD have their own advantages and disadvantages, and it's hard to say which is better than the other. As a result, consumer electronics manufacturers have begun to commercially introduce hybrid-type recorders that perform dual functions as DVD recorders and HD recorders. [0003] A hybrid type recorder equipped with a large-capacity HD suc...
