Problems solved by technology

However, Type C arranges 19 pins in a very small size, which greatly increases the precision requirements of interface manufacturing and increases manufacturing costs. At the same time, dense wiring also reduces the reliability of the interface. In fact, Type C HDMI Connectors have significantly fewer mating cycles than other connectors of similar size, such as Micro Universal Serial Bus (Micro USB) connectors
[0005] In addition, the handheld electronic device itself is small in size, increasing the interface takes up space on the one hand and increases the manufacturing cost on the other hand

Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. First, words and terms in each of the following examples are explained:

[0034] The so-called "handheld electronic device" refers to various electronic devices whose size is suitable for hand-held, including but not limited to: mobile phones, personal digital assistants (Personal Digital Assistant, PDA), tablet computers (Tablet PC), digital cameras, digital video cameras, MP3 / MP4 player.

[0035] The so-called "connector" refers to a component that connects two devices, usually including a socket or plug, and may also include an interface device coupled with the socket or plug. A connector can be a discrete component, or it can be integrated on a handheld electronic device.

[0036] When the following embodiments mention that A and B are "coupled", it means that the electrical signal passing through A and the electrical signal passing thro...

Abstract

The present invention provides a multipurpose connector for multiplexing a headset interface into a high-definition video / audio input interface, including a headset connector, a selecting switch, a high-definition video / audio transceiver, and an audio output module, where the headset connector includes a first audio terminal and a second audio terminal; the audio output module is configured to output an audio signal of the headset; and the selecting switch includes two lines, where when the selecting switch communicates with a first line, the first audio terminal and the second audio terminal are coupled to a pair of differential transmission lines respectively, and the differential transmission lines are configured to transmit high-definition video / audio data output by the high-definition video / audio transceiver; and when the selecting switch communicates with a second line, the first audio terminal is coupled to the audio output module. The present invention further provides a handheld electronic device which includes the foregoing multipurpose connector.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for quality of service configuration. Background technique [0002] Today's handheld electronic devices, such as smart phones, tablet PCs (Tablet PC), etc., generally have high-definition (High Definition, HD) video recording capabilities, and now many high-end smart phones have been able to shoot smooth 1080p resolution HD video. In addition, as high-definition video becomes more and more popular, a large amount of high-definition video is stored on many handheld electronic devices. However, due to the small screen of handheld electronic devices, it is difficult to play high-definition There is an urgent need for a way to output high-definition video to large-screen display devices such as televisions, projectors, and computers (PCs). [0003] High Definition Multimedia Interface (HDMI) is an interface for transmitting uncompressed dig...
