Abstract:
1. A data recording method for use in a digital broadcast receiver, comprising: receiving and decoding a digital broadcast in which video data and audio data are transmitted in the form of a transport stream to provide a received transport stream; connecting a first interface of the digital broadcast receiver to a corresponding interface of a recording apparatus; determining information corresponding to a transmission rate of the received transport stream; generating a recording rate setting command on the basis of the information corresponding to the transmission rate, when the transmission rate corresponds to a standard definition rate the recording rate setting command indicates that a recording rate should be set greater than or equal to a first specified value, and when the transmission rate corresponds to a high definition rate the recording rate setting command indicates that the recording rate should be set greater than or equal to a second specified value, the recording rate setting command not being a mode command or a single rate command; and transmitting the recording rate setting command to the recording apparatus through the first interface and the corresponding interface when the connection between the first interface and the corresponding interface is initiated, when a request command is received from the recording apparatus, or periodically after predetermined intervals.
