“…Additionally, this method can reduce power consumption, manufacturing costs, device weight, and transmission delay by removing compression modules. Typical encoder and decoder power consumptions are up to 8 W [5,6]. If there are no compression modules, they can reduce power consumption and can increase running time of portable communication devices used by infantry.…”

“…Then, the system uses the interlaced method in which 1080i * 30 fps = 0.75 Gbps instead of the progressive method. Therefore, this system does not exceed 1 Gbps and can communicate even if the channel condition is not good [5,6]. Increasing the transmission speed of the wireless network makes the uncompressed video streams transferrable for the multimedia services [7][8][9][10][11][12][13].…”

Under unpredictable wireless communication environments such as a battlefield, uncompressed video data is easy to restore and more effective to decipher than compressed video data when there are lots of errors in the received data. This paper proposes a wireless uncompressed video transmission system to ensure image quality even under a low signal to noise ratio (SNR). It utilizes a method of transmitting data asymmetrically on the basis of the image information in the wireless communication system using multiple antennas. The proposed algorithm is applied to the IEEE 802.11ac system and can improve about 5dB in terms of the peak signal to noise ratio under the SNR environment of 10 dB or less compared to an existing algorithm. From the simulation results, the proposed method is very suitable for wireless video surveillance systems that should provide video streams with a certain level of quality even under severe conditions.

“…Implementation of H.264/AVC encoder, however, requires enormous computational complexity. Several encoder LSIs have already been developed [2] [3] and achieved real-time encoding. Software-based HD quality (1280 x 720 pixels, 30 frames per second) real-time encoders are also developed [4], however, Full-HD quality (1920 x 1080 pixels, 30 frames per second) ones are still few.…”

This paper describes a software-based H.264/AVC HDTV real-time interactive CODEC architecture (named RISCA264-HD) using parallel processing. The RISCA264-HD consists of multiple high-speed encoder/decoder cores, an IP communication part, and an error recovery controller with FEC. It provides Full-HD quality (1920 x 1080 pixels, 29.97 frames per second) using parallel encoding, natural interactive conversation with low delay of less than 165 ms, and smooth visual communication free from macro block noises. This software with a home television and a home digital video camera achieves HDTV-quality bidirectional video communication via commercially IP broadband network.
