Ref design rolls for MPEG-4 network video servers

Video proCESsing IC company AverLogic Technologies Corp. has announced its latest MPEG-4 network video server reference design. This product leverages the company's MPEG-4 A/V encoding capability to stream real-time video over the Internet, enabling system designers to quickly develop a network video server or IP network camera. It can support video encoding up to 704 x 480 (704 x 576 for PAL video) resolution with MPEG-4 compression technology. Audio encoding supports stereo audio input or mono voice input with MPEG-1 layer II standard.

"Today's IP video streaming users are demanding extensive functionality, such as remote monitoring or recording, high-quality video streaming over existing IP networks, for example through more efficient compression technologies." says Kyle Chang, CEO of AverLogic Technologies. "AverLogic's MPEG-4 network video server reference design digitizes and compresses video and audio, and then transmits the compressed video and audio with TCP/IP protocol through Ethernet, Power Line or Wi-Fi, which allows high performance and fully configurable MPEG-4 compression. This solution enables applications for sending A/V over long distances, such as surveillance IP camera, network video server, Sony location free-like video device, SlingBox-like device, and so on."

"The MPEG-4 network video server reference design consists of RCA A/V connectors that can be connected to VCR, DV/V8 camcorder, surveillance camera, DVD player, TV STB and other video equipment," Chang continued. "The video encoder formats support MPEG-4 simple profile, variable or constant bit rate (VBR/CBR), programmable GOP size of I and IP, adjustable frame rate and picture resolution, etc. It supports up to 30fps for NTSC and 25fps for PAL, and variable resolution from QCIF to D1."

"Meanwhile, the application program provides preview with recording function, and playback functions that run in Web Browser by ActiveX technology. The network protocol supports TCP/IP, ARP, ICMP, HTTP, DHCP, DDNS, PPPoE, NTP and UPnP. The reference design is a mature solution that helps customers to introduce their end products in the market quickly," Chang added.
