Problems solved by technology

However, such a short distance of 50 to 100 meters limits the practical application of such systems
[0006] That is, such a radio VOD system using a high frequency band is considerably limited by the allowable distance between the base station and the mobile terminal
In order to increase the allowable distance, it is necessary to greatly increase the cost of building the system
In addition, since the number of users who can access the system at the same time is limited to 16, it is impossible to meet the needs of users beyond this limit
In addition, due to the use of high frequency bands, it will also increase the operating costs of mobile devices and switches

Embodiment Construction

[0035] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. For the purpose of brevity, some well-known functions or constructions are not described in detail so as not to obscure the understanding of the present invention with unnecessary detail.

[0036] figure 1 A radio VOD system according to an embodiment of the present invention will be explained.

[0037] refer to figure 1 , the first broadcast content server 10 stores and manages video files (ie, a video server), and the second broadcast content server 20 stores and manages audio files (ie, an audio server). A personal computer (PC) 30, which can be connected to PSTN (Public Switched Telephone Network) and / or LAN (Local Area Network) 40 required for remote access, is a server manager.

[0038] The server manager checks the user demand (or selection) list and various reservation states, and transmits the corresponding data list to the first and second con...

Abstract

A radio VOD (Video-On-Demand) system is disclosed. A server provides a video file and an audio file, and a server manager manages the server so as to transmit a video file and an audio file at a user's request. An exchange converts the video file and the audio file provided from the server through a network to the corresponding video and audio signals. A mobile terminal receives the video and audio signals from the exchange through separate channels, and reads only the user requested data from the received video and audio signals. The mobile terminal comprises first and second tuners for separately receiving the video signal and the audio signal, respectively; a signal processor for detecting a video signal and an audio signal, selected by the user, from the video and audio signals received through the first and second tuners; first and second decoders for decoding the video and audio signals detected by the signal processor, respectively; a video display for outputting the decoded video signal; and an audio output device for outputting the decoded audio signal.

Description

technical field [0001] The present invention generally relates to radio VOD (video on demand) systems. Specifically, the present invention relates to a radio VOD system, which can provide various multimedia files through radio communication when required by users. Background technique [0002] State-of-the-art radio VOD systems include a server as an information provider, a network, and an indoor receiver (eg, a set-top box). The server stores video information and related application software that controls the video information, and selectively transmits the video information to the end-user device (ie, set-top box) when requested by the end-user. [0003] For the network of the VOD system, a broadband network is adopted, and video information can be transmitted at a rate of several megabits per second. A set-top box is an indoor receiver installed at the end user, which acts as an end station for a broadband transmission line. The broadband transmission line is the phys...
