<p>A TS encoder for encoding video and audio signals in units of fields is provided. A transport stream (TS) encoding method for receiving an MPEG elementary stream and generating a transport stream includes the steps of (a) generating a packetized elementary stream (PES) header in units of fields of the elementary stream, (b) generating a PES header valid period signal for denoting the valid period of the PES header generated in the step (a) in units of fields, (c) recording the PES header generated in the step (a) and the elementary stream in synchronization with the PES header valid period signal generated in the step (b), (d) generating a TS header period signal for denoting a period in which the TS header is to be recorded, (e) reading the PES header generated in the step (a) and the elementary stream in synchronization with the TS header period signal generated in the step (d), and (f) generating the TS packet by adding the TS header to the PES header read in the step (a) and to the elementary stream, according to the timing at which the TS header is to be recorded.</p> |
