Abstract: Disclosed are a method for informing a user of video receiving delay and a broadcast receiving apparatus thereof. The method includes separating a video signal from a received broadcast signal, and decoding and storing the video signal; determining if a video signal corresponding to the first frame of video is completely decoded, after a certain amount of time from the beginning of receiving the broadcast signal; and processing to display information on video receiving delay, if it is determined that the video signal corresponding to the first frame of the video is not completely decoded. When audio is normally output but corresponding video is not output yet at the beginning of receiving music broadcast, a user will be informed of the video receiving delay. Accordingly, the user can recognize that video will be output soon and will not think that the broadcast receiving apparatus is malfunctioning.

Abstract: A fly-back pulse width adjustment circuit and a method for adjusting the width of a fly-back pulse which are applied to a video signal processing unit realized as one chip are provided. The fly-back pulse width adjustment circuit is built into a video signal processing unit including a video amplifier, an on screen display unit, and a horizontal/vertical synchronous signal processing unit within the video signal processing unit realized as one chip. Moreover the fly-back pulse width adjustment circuit includes a pulse shaping unit which shapes the fly-back pulse received from the outside via an input terminal and then applies the shaped fly-back pulse to the horizontal/vertical synchronous signal processing unit, and a pulse-width adjustment unit which adjusts the width of the shaped fly-back pulse in response to a predetermined control signal, generates the horizontal blank signal having a different occurrence time from the result of the adjustment in response to a selection signal, and applies the horizontal blank signal to the video amplifier and the on screen display unit. The fly-back pulse width adjustment circuit which is provided as external components of a chip is designed to have a simple structure, and consequently it is possible to build the fly-back pulse width adjustment circuit into a video signal processing unit realized as one chip. Moreover, the width of a fly-back pulse can be adjusted by control of a microcontroller or a microcomputer, thereby applying the fly-back pulse width adjustment circuit to various monitors. In addition, the fly-back pulse width adjustment circuit can input the fly-back pulse via one terminal without an external circuit. Therefore it is easy to manufacture a printed circuit substrate with use of the fly-back pulse width adjustment circuit.
