Embodiment Construction

[0028] The video communication system based on the HDMI interface of the present invention is based on the HDMI interface and an IP network, and utilizes a high-definition video source, a high-definition video signal codec and an HDMI display device to realize collection, transmission and display of high-definition video signals.

[0029] The system is based on the HDMI interface, including a sending end and a receiving end interconnected through an IP network; the sending end obtains the original data of the high-definition video source through the HDMI interface, and encodes the original video data through the high-definition video encoding module and transmits it to the receiving end , the receiving end passes through a video decoding module and post-video processing, and finally outputs to a display device with an HDMI interface for display. The HDMI is an abbreviation of High Definition Multimedia Interface (High Definition Multimedia Interface). The IP network includes a...

Abstract

The system comprises a sending end and a receiving end both connected via an IP network; said sending end gets the original data of the HD video source via HDMI interface, encodes the original video data through a HD video encoder, and transmits the encoded data to the receiving end; said receiving end decodes the received data via a decoder, processes it via a video post processor, and outputs it to a display device with HDMI interface.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an HDMI interface-based video communication system and method integrating high-definition video collection, transmission and display. The system and method are based on HDMI collection and display. Wherein, the HDMI refers to a high definition multimedia interface (High Definition Multimedia Interface). Background technique [0002] High-definition video is an emerging market demand with broad development prospects and huge market capacity. With the rise of high-definition video acquisition equipment (such as high-definition digital cameras, high-definition digital video cameras, etc.), the definition of video images is getting higher and higher. However, in existing multimedia video communication systems, standard-definition video interfaces and common video codec standards are still used to compress high-definition images and videos (such as 1920×1080i or 720p) i...
