Description

多规格影音信号传输装置
技术领域
本发明涉及一种影音信号传输装置，特别是涉及一种可以将移动装置与显示装置相连接的多规格影音信号传输装置。
背景技术
近年来由于移动装置的大量普及，使用移动装置观赏或储存多媒体影音信号的需求，也随着大幅增加。目前使用于移动装置的多媒体影音信号的规格，主要有移动高清连接(MHL，Mobile High-Definition Link)以及移动显示接口(MyDP，Mobility DisplayPort)两种，而接口接口(interface port)一般则使用微小通用总线(micro-USB)接口。
另一方面，液晶显示技术的发展，也使得显示装置的价钱大幅降低，应用与拥有的需求也大量增加。然而，现今显示装置的多媒体影音信号接口，大多为19-pin(信号接点19个)的高清晰度多媒体接口(HDMI，High-Definition Multimedia Interface)规格及HDMI接口。若要将移动装置与显示装置的多媒体影音信号双向互传，势必产生信号规格冲突的问题。
为了使不同规格的MHL、MyDP或USB信号可以与HDMI信号轻易的双向互传，一个既可以利用现有移动装置接口与显示装置接口，且成本低廉、轻巧又使用方便的多规格影音信号传输装置便迫切的亟待发明。
发明内容
本发明的目的在于，提供一种多规格影音信号传输装置，可以方便的将移动装置与显示装置相连接，并可以进行多规格信号传送对单一规格信号接收，或单一规格信号传送对多规格信号接收的双向影音信号传输。

本发明的目的及解决其技术问题还可采用以下技术措施进一步实现。
较佳的，前述的多规格影音信号传输装置，其中该第一端口与移动装置信号相连接，且该第二端口与显示装置信号相连接。
较佳的，前述的多规格影音信号传输装置，其中该电路模块固设并信号连接于该显示装置，且该显示装置借由该第一传输线及该第一端口与该移动装置信号相连接。
较佳的，前述的多规格影音信号传输装置，其中该电路模块固设并信号连接于该移动装置，且该移动装置借由该第二传输线及该第二端口与该显示装置信号相连接。
较佳的，前述的多规格影音信号传输装置，其中该显示装置为电视机或显示器或投影装置。
借由上述技术方案，本发明至少具有下列优点及有益效果：
一、使用现有移动装置接口与显示装置接口，不增加额外设备或成本；

为更进一步阐述本发明为达成预定发明目的所采取的技术手段及功效,以下结合附图及较佳实施例，对依据本发明提出的多规格影音信号传输装置其具体实施方式、结构、特征及其功效，详细说明如后。
如图1所示，为实施例一种多规格影音信号传输装置100，其包括有第一端口10，电路模块20，第一传输线30，第二端口40以及第二传输线50。电路模块20以第一传输线30及第二传输线50分别连接第一端口10及第二端口40，第一端口10及第二端口40再分别连接至移动装置60及显示装置70。
如图1及图2所示，第一端口10可以为微型通用串行总线接口(micro-USB port)，第一端口10与移动装置60信号相连接，用以双向传输第一信号，其中第一信号可以为移动高清连接(MHL)信号、移动显示接口(MyDP)信号或通用串行总线(USB)信号。亦即，如图1所示的第一端口10，可以使多种规格的信号通过微型通用串行总线接口(micro-USB port)进行双向传输。
如图2所示，为移动高清连接(MHL)信号、移动显示接口(MyDP)信号或通用串行总线(USB)信号等，皆可以经由第一端口10进行双向传输的实施例示意图。
如图1及图2所示，电路模块20，用以将第一信号转换为第二信号，或将第二信号转换为第一信号，其中第二信号为高清晰度多媒体接口(HDMI)信号。亦即电路模块20是将移动高清连接(MHL)信号、移动显示接口(MyDP)信号或通用串行总线(USB)信号，与高清晰度多媒体接口(HDMI)信号进行规格的互相转换。
又如图1及图2所示，第一传输线30，用以连接第一端口10及电路模块20，移动装置60经由第一端口10及第一传输线30，将移动高清连接(MHL)信号、移动显示接口(MyDP)信号或通用串行总线(USB)信号传送至电路模块20，或自电路模块20接收移动高清连接(MHL)信号、移动显示接口(MyDP)信号或通用串行总线(USB)信号。

再如图1及图2所示，第二传输线50，用以连接电路模块20及第二端口40。亦即，第二传输线50与第二端口40将电路模块20与显示装置70相连结，并进行电路模块20与显示装置70间高清晰度多媒体接口(HDMI)信号的双向传输。
经由如图1及图2所示实施例的多规格影音信号传输装置100，移动装置60可以将多种规格的影音信号传输至具有单一规格信号接口的显示装置70，而具有单一规格信号接口的显示装置70亦可以将影音信号传输至具有多种信号规格接口的移动装置60。也就是说，本实施例的多规格影音信号传输装置100，可以进行多规格信号的传送端与单一规格信号的接收端的双向信号传输，也可以进行单一规格信号的传送端与多规格信号的接收端的双向信号传输。
如图3所示，本实施例为一种多规格影音信号传输装置200，其电路模块20可以固设并信号连接于显示装置70之中。如图3所示多规格影音信号传输装置200的连接方式，显示装置70可以仅借由第一传输线30及第一端口10与移动装置60信号相连接，其在连接线的制造、储存或使用上较为简便。
如图4所示，本实施例为一种多规格影音信号传输装置300，其电路模块20可以固设并信号连接于移动装置60之中。如图4所示多规格影音信号传输装置300的连接方式，移动装置60借由第二传输线50及第二端口40与显示装置70信号相连接，其在连接线的制造、储存或使用上亦有较为简便的优点。
如图1至图4所示的多规格影音信号传输装置100、200或300，其中显示装置70在实际应用上，可以为具有高清晰度多媒体接口接口(HDMIport)的电视机或显示器或投影装置。
以上所述，仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明,任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内,当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例,但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
