Description

Technical Field

[0001] The present invention belongs to the technical field of smart glasses charging cases, and specifically relates to a smart glasses charging case with wireless HDMI video transmission function. Background Art

[0002] Smart glasses are wearable intelligent devices integrating advanced sensors, display screens, processors, and communication modules. They look like ordinary glasses but have powerful functions. They can superimpose virtual information in the user's field of vision to achieve an augmented reality (AR) experience, such as real-time display of navigation routes, translation of foreign language menus, marking of surrounding object information, etc.; some also support voice interaction and gesture control, allowing users to complete command input without manual operation; at the same time, they can be connected to devices such as mobile phones and computers to receive notifications, messages, and even make video calls. Smart glasses bring innovative applications to multiple fields such as medical care, industry, education, and entertainment, greatly improving the efficiency of information acquisition and the convenience of interaction, and are gradually becoming a powerful assistant in people's work and life.

[0003] Traditional smart glasses mainly rely on wired connection methods to achieve HDMI video transmission. Usually, they need to use external devices such as mobile phones to transmit signals through physical data cables. This connection method has significant usage limitations, mainly reflected in the fixed position between devices caused by physical cables, which restricts the operating freedom of smart glasses in mobile scenarios. At the same time, frequent plugging and unplugging of interfaces easily cause connection stability problems, and the audio and video transmission functions cannot be synchronized during device charging. Existing wireless transmission solutions mostly use general wireless protocols for video forwarding, and there are problems such as insufficient bandwidth to support the transmission of high-resolution and high-frame-rate videos in the HDMI 2.1 standard, loss of color depth and color gamut information during the encoding and decoding process, and inaccurate separation accuracy of audio signals resulting in channel positioning deviation. In particular, it is impossible to achieve hardware coordination of charging and wireless audio and video transmission within a single device; in addition, current charging case products only have a single function of electrical energy supply, and their functions are very single, so they need to be improved.

[0045] Through the collaborative innovation of OFDM modulation and TSN technology, anti-interference transmission of HDMI audio signals is achieved in the 60GHz high-frequency band. Combining the combined application of adaptive frequency hopping and AAC3.0 codec, the end-to-end transmission delay is greatly reduced while maintaining CD-level sound quality.
