Recording apparatus

Abstract

A recording apparatus performs bit rate conversion on an input stream and records the input stream with additional data such as captions and a weather forecast left therein into a recording medium in consideration of the remaining capacity thereof. A recording apparatus (10) performs bit rate conversion on an input stream including video data, voice data and additional data and records the converted input stream. The recording apparatus (10) comprises a control unit (15) which calculates a target total bit rate which is a target of the input stream on the basis of the recording time of the input stream and the remaining capacity of the recording medium and sets a target bit rate of the video data with respect to the calculated target total bit rate and a transcoder (13) which measures an actual total bit rate of the input stream after starting the bit rate conversion on the basis of the target bit rate of the video data. The control unit (15) adjusts the target bit rate of the video data on the basis of the difference between the actual total bit rate and the target total bit rate so that the input stream including the additional data may fall within the remaining capacity of the recording medium.

Description

technical field [0001] The present invention relates to a recording device, and more specifically, to a recording device having a function of converting the bit rate of an input stream and recording it. Background technique [0002] Among recent high-definition television recorders, there are known recorders capable of recording and reproducing digital broadcasts such as terrestrial digital broadcasts and BS digital broadcasts on HDD (Hard Disk Drive) as they are. In addition to video and audio, these digital broadcasts also include data linked parts such as subtitles and weather forecasts (hereinafter referred to as additional data). [0003] For example, a technique is disclosed in Patent Document 1 for not only recording / reproducing such additional data but also recording / reproducing data broadcasting, broadcasting other than data broadcasting, and having related data other than broadcasting flow. According to this, the data broadcast and the like are recorded by separa...

Problems solved by technology

[0013] However, according to the technology disclosed in the above-mentioned Patent Document 1, although it is possible to save and edit without discarding the additional data, there is a problem that when you want to edit the BD (Blu-ray Disc, Blu-ray Disc) without discarding the additional data or DVD, etc., because the amount of additional data varies for each channel or program, the bit rate cannot be estimated accurately, and recording cannot be performed considering the remaining capacity of the BD or DVD.
