KR950028527A - APPARATUS AND METHOD FOR FASTING THE PLAY - Google Patents

Abstract

The present invention relates to a jump device and method using an MPEG bit stream format suitable for fast playing an image according to a user's command. The present invention relates to a case where a bit stream is continuously read from an arbitrary position in a conventional jump operation. Although it is easy to generate an error such as a memory overflow without finding information to be performed and a continuous bit stream is required, the present invention also uses the I-screen start address by randomly accessing the I-screen according to the jump instruction. By controlling jumps, analysis of bit streams is skipped, memory overflow in the system that can occur during jumps is prevented, system malfunctions are prevented, and a series of screens starting with every I-screen By controlling the occurrence of jumps, unnecessary actions such as system reset and warm-up can be avoided. It is to improve the above drawbacks.

Claims (4)

A system decoder (1) for receiving a bit stream according to an MPEG and decoding a private-stream; an address decoder (2) for receiving a signal from the system decoder (1) to decode an I-screen start address; A storage unit (3) for storing an I-screen start address of the decoder (2); an input unit (4) for the user to selectively enter commands including play, stop, and jump; and the input unit (4) Message control unit 5 for receiving the signal of the control unit to perform the corresponding mode according to the user's command; connected between the message control unit 5 and the storage unit 3 according to the user's selected mode execution A first switching unit 6 for switching; and a second switching unit 7 for selectively switching according to the mode of the message control unit 5; the second switching unit 7 and a system decoupling; A video decoder 10 connected between (1) to decode the video signal from the system decoder 1 and to execute the mode in accordance with the switching of the second switching unit 7; An audio decoder 8 for receiving a signal and decoding an audio signal; and an MPEG bit stream format including a clock control unit 9 for receiving a signal from the system decoder 1 and controlling a clock for controlling a system. Jump device using the. The jump device according to claim 1, wherein the first switching unit (6) uses the MPEG bit stream format to switch according to a jump or normal mode of the message control unit (5). The jump device according to claim 1, wherein the second switching unit (7) selectively switches according to a jump or normal mode of the message control unit (5). If there is a jump command, the current I-screen start address is set as the previous I-screen start address from the current position, and the next I-screen start address is set to the I-screen start address closest to the position selected according to the jump command. Defining steps 21-23; and if the current I-screen start address is different from the next I-screen start address, performing a fast play according to a jump instruction with the current position as the next position (24-26). Using the MPEG bit stream format comprising steps 24 and 27 for normal play to be performed when the current I-screen start address and the next I-screen start address are the same. Jump way. ※ Note: The disclosure is based on the initial application.
