Problems solved by technology

The index table is used to confirm the position of the data stream when the audio and video files are fast forwarded or rewinded. The time required to index the table and store it in the memory is the cause of the delay in the initial time from when the command to reproduce the specified audio and video is issued to when the related audio and video are heard / watched

Abstract

This invention relates to a sound and image regenerating method in a radio streaming-media system, which sets an index list about loaded and regenerated sound and images, when a sound and data flow file of image files sent by a sending device are received and processed by a receiving device of sound and images and the index list must be used when passing through the user interface, it judges if the index list is in the storage, if not, the sound and image receiving device will utilize a radio interface device to apply for the index list to the sending device and receives it and deals with the event with the list, so when sound and image files are regenerated, the initial time from issuing the regeneration order to the time watching / listening to the related sound and images is shortened.

Description

technical field [0001] The present invention relates to a method for reproducing sound and video in a wireless streaming media system, which is as a method for sending specified sound and video files wirelessly by a sound and video file sending device, and the sound and video file receiving device reads the above-mentioned files A method of reproducing sound and video in a wireless streaming system (Wireless Streaming) that receives and outputs through a screen and a speaker. Background technique [0002] With the development of communication technology, Bluetooth, Wireless Fidelity (WiFi: Wireless Fidelity), Ultra Wide Band (UWB: Ultra Wide Band) systems, and Wireless Local Area Network (WLAN) are wireless interfaces for short-distance communication. Devices are developed in large numbers. [0003] With the development of communication technology, the transmission speed of the wireless interface equipment is continuously accelerated, reaching the level of fully transmittin...
