PC-Based Encoder/Decoder
This PC-based unit is the latest encoder/decoder from our laboratories, utilizing the most advanced technology in video/audio encoding/decoding, hard disk record and TCP/IP.

Physical description 

• Max 64 video in (PAL, NTSC)
• Max 64 audio in (linear in)
• 1 line in (for voice talk)
• 1 10/100/1000M Ethernet
• support Up to 42 Hard Drives IDE/SATA/SCSI/RAID
• 1 RS-485 for keyboard, 1 RS-485 for PTZ control
• 1 RS-232
• 1 USB
• 1 VGA
• 19-inch case (450mm*450mm*95mm) (optional larger case for systems above 32 channels)

Function :

The PC based encoder/decoder adopts a high performance Windows Embedded XP real-time multi-tasking operating system and hyperthreading CPU, to perfectly implement all the functions needed to build a broadcast IPTV system.

Compression function:

• Support maximum 64 channels video in. Each channel can be compressed independently in 25F/S (PAL) or 30F/S (NTSC), using H.264 algorithm. Both variable bit-rate and variable frame rate are supported.
• Support max 64 channels audio in. Each channel can be compressed independently, using an OggVorbis audio standard with MP3 quality. The output bit-rate is 16 kbps.
• The output video and audio streams are integrated to generate the synchronized H.264 stream. Video and audio coincide with each other from beginning to end when the stream is played back.
• Supports following resolution on every channel:
  PAL:4CIF (704*576), DCIF(528*384), 2CIF(704*288),CIF(352*288), QCIF(176*144);
  NTSC: 4CIF (704*480), DCIF(528*320), 2CIF(704*240),CIF(352*240), QCIF(176*120)
• Supports position configurable OSD & LOGO. Supports watermark.

Network Functions:

• Supports TCP/IP (ARP, RARP, IP, ODP, TCP, PPP, PPPoE, DHCP, SNMP, etc).
• Supports broad-band transmission (ADSL, etc).
• Supports narrow-band transmission (PSTN, etc).
• Streams of one or more channels, Encoder/Decoder's running state can be accessed through network.
• Encoder/Decoder's parameters can be set through the network.
• Supports remote control of Pan/Tilt/Zoom Cameras.
• Streams can be recorded in a remote host PC .
• Files in the Encoder/Decoder can be downloaded to or remotely played in a remote host PC.
• Supports remote upgrading.
• PC hosts can gain direct control of the Encoder/Decoder's RS-232 or RS-485 port.
• Supports voice talk between host in broadcast center (back end) and Encoder/Decoder's (front end)
• Supports embedded web server. Browser can be used to access Net DVR.

Storage Functions:

• Won't lose frames when switch record files
• Supports hard disk sleep mode.
• Supports FAT32 file system. 
• Supports HDD smart
• Supports cyclic and non-cyclic record mode.
• Supports network access storage (NAS). 
• Supports USB flash disk, USB hard disk, USB CDRW for backup.

Preview & Playback Functions:

• Supports Monitor; Supports VGA;
• Switch quickly in preview mode;
• Supports partial zone sheltering;
• Supports local file Play and time play, support play fast, play slow, pause, play frame one by one, etc;
• Supports OSD, LOGO

PTZ control:

• Supports Pan-Tilt-Zoom control and Preset through front, keyboard and network;
• Supports most popular camera protocol.
• Ability to customize new camera protocol.
