Abstract: A video transmission system generally consists of three main parts: A video data acquisition unit, transmission networks and play back terminals. The video data acquisition unit is one of the main parts. This paper focuses on an embedded video data acquisition hardware and software design. In the design, a PXA310 is used as a primary processor. The software design is based on an Android operating system. First, the paper briefly introduces the hardware design including overall scheme and the selection of key components. Then, the software design of the video data acquisition unit is introduced more detail, which includes the transplant of an Android operating system and the application software implementations for video data acquisition and processing. The modifications of BLOB boot program, the modifications of the operating system kernel and the NAND FLASH driver transplantation are described in more detail. The description of the video data acquisition software design includes the use of the Android internal class "Mediarecorder", the method of extracting frame data according to 3GP and H.264 protocol, and the use of the socket interface to transmit frame data to a 3G wireless network called TD-SCDMA. The designed acquisition unit has been tested in a video surveillance and monitoring system and the experiment results are given at the end of the paper.

 

Keywords: Networking video monitoring, Android, System transplant, Video data acquisition, H.264, Transmission unit.
