Unicode and RTSP...


The HMI now supports Unicode. Unicode is a computing industry standard for the consistent encoding, representation and handling of text expressed in most of the world's writing systems.

Two additions for video camera support have been added.

The first addition is generic MJPEG decoding that should work with all cameras, that support MJPEG via HTTP (Hypertext Transfer Protocol), regardless of ‘manufacture’ embedded data in the header.

The second addition is support for RTSP (Real time streaming protocol). The main reason for adding RTSP support was to add H.264 decoding. The list of supported protocols is too large to list in this blog. Testing of RTSP was performed using H.264 and MJPEG decoding using 4 different video cameras/encoders.


(H.264/MPEG-4 Part 10 or AVC (Advanced Video Coding) is a standard for video compression, and is currently one of the most commonly used formats for the recording, compression, and distribution of high definition video.)
