Abstract
The invention provides an effective means that realizes a long-hour recording and multi-channel simultaneous recording of TV broadcast programs without sacrificing the picture quality in reproduction. The invention also enhances user-friendliness in recording multiple channels. The invention provides a transcoder for the digital broadcast, utilizes program information during recording, and adaptively controls the recording bit rate in correspondence with the maximum transfer rate of a record medium.
Claims18
A recording apparatus that records video and audio signals, comprising:
- an aspect ratio detection module that detects aspect ratios of inputted video and audio signals, and
- a control module that controls recording of the video and audio signals by a bit rate corresponding to a detection by the aspect ratio detection module.
A recording apparatus that records video and audio signals, comprising:
- a resolution detection module that detects resolutions of inputted video and audio signals, and
- a control module that controls recording of the video and audio signals by a bit rate corresponding to a detection by the resolution detection module.
A digital recorder that records digital broadcast programs, comprising:
- a detection module that detects bit rates of the digital broadcast programs,
- a user setting module that a user sets recording bit rates in recording the digital broadcast programs,
- wherein a bit rate detected by the detection module and a bit rate set by the user setting module are compared, and when the bit rate detected by the detection module is lower, the program is recorded with a digital broadcast bit rate.
A digital recorder that records digital broadcast programs, comprising:
- a detection module that detects bit rates of the digital broadcast programs,
- a program type recognition module that recognizes program types of the programs,
- a bit rate setting module that sets recording bit rates to each of the program types corresponding to recognitions by the program type recognition module,
- wherein a bit rate detected by the detection module and a bit rate set by the bit rate setting module are compared, and when the bit rate detected by the detection module is lower, the program is recorded with a digital broadcast bit rate.
A digital recorder that records digital broadcast programs, comprising:
- a user setting module that a user sets recording bit rates in recording the digital broadcast programs, wherein:
- the programs of which recording the user designates explicitly are recorded with recording bit rates set by the user setting module, and
- the programs of which recording the user does not designate explicitly are recorded with lower bit rates than the recording bit rates set by the user setting module.
A digital recorder that records digital broadcast programs, comprising:
- plural trans-code modules having a first output part that outputs with bit rates of the digital broadcast programs, and a second output part that outputs with lower bit rates than the bit rates of the digital broadcast programs.
A recording apparatus comprising:
- a reception part that receives modulated data,
- a demodulation part that demodulates data received by the reception part,
- a demultiplexing part that extracts desired data from data demodulated by the demodulation part,
- a control part that performs a control corresponding to attribute information of data extracted by the demultiplexing part,
- a coding part that trans-codes the data on the basis of the control of the control part, and
- a recording part that records data trans-coded by the coding part.
A digital recorder that records digital broadcast programs, comprising:
- a recording module that records the digital broadcast programs,
- an erasing module that erases programs recorded by the recording module, and
- a control module that controls to erase the recorded programs on the basis of attribute information of the programs recorded by the recording module.
- wherein the programs that the control module controls to erase are recorded with lower bit rates than those of the programs that the control module does not control to erase.
A recording apparatus that records video signals, comprising:
- an aspect ratio detection module that detects aspect ratios of inputted video signals, and
- a control module that controls recording of the video signals by a bit rate corresponding to a detection by the aspect ratio detection module.
A recording apparatus that records video signals, comprising:
- a resolution detection module that detects resolutions of inputted video signals, and
- a control module that controls recording of the video signals by a bit rate corresponding to a detection by the resolution detection module.
