Description
[technical field]
The utility model relates to a kind of mobile unit, is specifically related to a kind of vehicle-mounted no dish multimedia recreation mobile unit based on embedded microprocessor.
[background technology]
Existing vehicle-carrying DVD navigator is also to connect a GPS navigation plate on the basis of original vehicle-carrying DVD disc player on the DVD mainboard, plays the equipment that can DVD playing back can realize the GPS navigation function again.If do not consider the navigation feature of this vehicle-carrying DVD navigator, with regard to amusement function, when DVD playing back, read the audio, video data of DVD laser disc by the DVD shaven head, add the video decoding chip processing video data by single-chip microcomputer, by the OSD processing menu operation and the menu demonstration of video decoding chip.Single-chip microcomputer and video decoding chip processing video data limited in one's ability, the high definition 3D video data of high compression ratio can't be handled, and the figure of OSD display menu is single, and dull coloring is being done exercises when electing simultaneously, and response speed is also very slow.
On the other hand, the DVD shaven head is that collection physics, optics, machinery and an electronics are the product of one, and cost is very high, and vehicle-carrying DVD is because temperature and vibrations simultaneously, and the DVD shaven head is easy to that there was a mechanical failure, causes reading dish.
Because defining the volume of DVD drive, the bulk factor of DVD dish case and DVD CD can not narrow down to very little scope simultaneously, as a kind ofly be convenient for carrying, low-cost storage medium, it has the unrivaled advantage of other data storage mediums at present, but because the DVD CD damages easily, and its memory space is little, and along with the continuous development of new memory technology, it becomes and more and more is not suitable for the needs of later vehicle mounted guidance amusement equipment.

Solid state hard disc (SSD) is the hard disk made from solid-state electronic storage chip array, because solid state hard disc does not have the rotating media of common hard disk, thereby shock resistance is splendid, working temperature is very wide simultaneously, the electronic hard disc of extended temperature can be operated in-45 ℃～+ 85 ℃, just can remedy above-mentioned said problem on the vehicle mounted guidance amusement equipment so it is applied in.
But solid state hard disc carries easily not as good as CD, and the interface of the data read of solid state hard disc is also very complicated, so solid state hard disc basically can not be as the careless replacing of CD, carry, such situation is difficult to obtain upgrade with regard to having caused the audio-video document in the vehicle mounted guidance amusement equipment, want the words upgraded also can only an external memory device to copy in the solid state hard disc audio-video document in this memory device to storage to upgrade original data file, like this just very inconvenient.
In sum, present technology has following shortcoming at least:
1. to add the video decoding chip video decoding capability not strong for single-chip microcomputer, can't realize the broadcast of high compression ratio video format;
2. menu operation interface figure is simple, and dull coloring is operated dumb simultaneously.
3.DVD CD-ROM device and micro harddisk use on mobile unit easily and damage;
4. the audio-visual video data on the mobile unit can't in time obtain upgrading;
