AP-SVTC2000 Video Transcoder (Video Codec, Video Resolution), RTSP Streaming Server Video Transcoder (H.265->H.264, H.264->H.265)




RTSP video streaming server and recording server is one of main core servers of AddPac Smart VMS software. RTSP video streaming software block is applicable to various application services due to RTSP based structure. Linux based RTSP streaming server software block is embedded with RTSP server and RTSP client. It is a RTSP protocol based which is located between video encoder and video decoder to distribute the HD video bit stream. It can support full HD video stream (for example, Up to 32 channels, output 64 channels).RTSP streaming server is designed to perform RTSP client function in input which receives the video bit stream from HD video encoder (RTSP Server). It performs the RTSP server function in output and designed to transmit the video bit stream to video decoder (RTSP Client) through On-Demand. Transport layer protocol uses TCP protocol as mandatory for the safe packet transmission in input. To cope with various application services in output, it supports the TCP or UDP protocol concurrently as an option. A video DSP based H.264 full HD video decoder and various media players such as VLC, GOM player, AddPac smart TVMS viewer can be RTSP client and perform video streaming transmission service based On-Demand by using RTSP streaming protocol.

AddPac video streaming server is designed by RTSP N:M client and server structure and its extensibility is very powerful. Also, this video streaming server is optimized for large scale CCTV deployment. RTSP video streaming server supports parallel, cascade style connection structure, and this streaming server is applied for various video streaming server topology. Several SLAVE RTSP video streaming servers can be managed by one single MASTER management server. Also each RTSP video streaming server can have a management server independently.

AP-SVTC2000 RTSP streaming sever video transcoder is a special version of AddPac Technology's RTSP video streaming server solution. This AP-SVTC2000 supports video trancoding server (video codec , bit rate) function and RTSP video streaming server function concurrently.  Generally, for example, AddPac ISMS (integrate security management system including CCTV VMS software) software for low bit rate satellite CCTV application supports  H.265 video codec, smart CCTV viewer software for very low satellite bandwidth (128kbps, 256kbps, etc), real-time satellite bit error rate estimation function (RTCP backward channel), satellite network adaptive video bit rate control (picture size, frame rate), real-time satellite network status display, etc.  Normally, recently released highly compressed H.265 video codec requires large performance CPU processing power. Legacy embedded RTSP based video decoders cannot handled H.265 video codec, just only supports H.264 video codec. AddPac CCTV VMS software supports various legacy video decoders, for example, H.264, H.263 video decoders  by using AP-SVTC2000 RTSP based Video Transcoder.
