Abstract
The invention provides a method for updating a program list of a DRM (Digital Rights Management) receiver, in particular relating to the technical field of digital audio brocading. The method comprises the step of a PC (Personal Computer)-DRM program processor is arranged on a PC and sends an instruction, so that a system program information reader can read the program list information released by a broadcast information network from the DRM broadcast information network; a program information analyzer analyzes the program list information released by the broadcast information network, and the analyzed information is stored in a program information storing device; a program information editor manually manage and correct the program information, and a program information display updates and displays the program list information in the program information storing device in real time; the program list is edited and updated on the PC, so that the convenience is improved; and the program list is read from the broadcast network, so that the updating speed is increased. According to the method, the defect that a common radio can not edit the program information conveniently, and the problems that the method that the common radio manually edits and updates the program is not suitable for the updating of the program list of DRM digital audio.
Description
Technical field
The present invention relates to DAB Technology field, especially relate to a kind of method that Fast synchronization upgrades DRM receiver the rendition list.
Background technology
People depend on long wave, medium wave, shortwave amplitude-modulation receiver for a long time, receive lastest news and music program.But due to the intrinsic abominable of this transmission channel, as ionospheric fluctuation, the radio interference of Doppler effect and moment, causes the quality of reception of this type of receiver poor.Because its area coverage transmitted is comparatively large, therefore this emitting-receiving system is still widely adopted.And FM radio receiver is due to its strong interference immunity, so be widely used in local music broadcast, but due to its propagation distance and the availability of frequency spectrum low, so operation costs are higher.
Being proposed by European Broadcasting Union and the standard of the digital radio receiver of below the 30MHz passed through, proposing to solve above problem just.This DRM system adopts advanced audio compression techniques and channel coding technology, orthogonal frequency division modulated technology and real-time characteristic of channel estimating techniques, can in the frequency bandwidth of existing analog AM, and use different DRM mode of operations according to the feature of present channel, realize high efficiency band utilance and jamproof good compromise.Simulation broadcast receiver upgraded the method for the rendition list is in the past so substantially: manually arrange program frequencies, and button is preserved and upgraded program.Because DRM system can accept the expansion of region, broadcasting station, the number of programs that can receive increases greatly.Make to upgrade programme in this way, the slow feature of renewal speed just clearly.In order to address this problem, inventors herein propose a kind of method upgrading the rendition list.This method is editing and updating the rendition list on PC, adds convenience; Adopt and read the rendition list from radio network, improve renewal speed.Solve common broadcast receiver manual editing and upgrade the problem that program method is not suitable for DRM digital audio broadcasting renewal programme.
Dutch royal N.V. Philips' Optical Lamp Ltd., Co discloses the content of " generating the method for TV or broadcast program listing from table of given delivery time " by name in No. 01803518.3 patent, be mainly used for broadcast event or the broadcast program overview program of record: the event selected from program guide for recording forms a list, they are showing with on the screen of timeline, and are presented on the accurate position of this timeline.This makes the order of user to the program in list have one always to see.It is diverse that its object and content and the present invention innovate to overcome technology prejudice.
