RT-AV Station is 19″ rack device comprised of processing unit (PC computer) and RT-AV100 A/V grabber device. Depending on use-case, RT-AV Station is available in 2 options:

  • RT-AV110 – Standalone general purpose test station with audio and video acquisition capability suitable for STB/DVD/Blu-ray testing. This test station is perfect match for use-cases in which captured signal is processed offline. Some of example use-cases are functional testing, head-end monitoring and production line testing.
  • RT-AV140 – Standalone embedded PQM (Picture Quality Measurement) test station for real-time signal artifact detection of audio and video signals up to 1080p30 (1080i60). Station is aimed for deployment in non-referent systems for detection of blocking, packet loss, black screen and other video artifacts. Test results are available over network using Simple Network Management Protocol (SNMP).

Artifact detection

RT-AV140 station comes with PQM Embedded application which performs real-time analysis of the live signal, registers and shows all detected artifacts in an easy to understand, graphical way. Developer section of the site provides detailed description of each audio or video artifact that may be captured within BBT platform. Some of important artifact detected in live signal are also listed here:

  • Packet loss and blocking artifact detection related to error in signal transportation media or MPEG2 compression.
  • Image absence which is defined as zero temporal activity and zero spatial activity for a specified period of time when a known moving video output should be present.
  • Blurring which is defined as a loss of image sharpness on a static image which persists for a specified number of video frames.
  • Ringing which is defined as a high frequency noise near edges.
  • Field loss which is defined as “interlace-like” artifacts.



Connectors Go to top

RT-AV110 device contains wide variety of analog and digital, SD and HD video connectors, coupled with analog and digital audio connectors for maximal connectivity. Besides connectors, there are two LEDs indicating network connection (LINK) and presence of a signal on selected video/audio interface (STATUS). RT-AV110 has the following connectors:

connectors_pack_HDMI 2 x HDMI input Type A:Two type A receptacle HDMI connectors are provided for two HDMI inputs. Use HDMI wherever possible for the best quality 10-bit uncompressed video input, capture and output. If peripheral equipment has a variety of outputs, look to see if it has either HDMI output or SDI output, and use it where possible. Most today’s equipment that offers HD material provides HDMI (Blu-ray players, HD cameras, DTV’s, etc.). HDMI supports both standard and high definition video. Simply connect standard HDMI cable to RT-AV110’s HDMI connectors.
connectors_pack_Composite video 2 x Composite (CVBS):BNC connectors support composite NTSC or PAL input and output. Connect an NTSC or PAL composite video cable from a VTR, Camera, or other source to the Composite In BNC. Composite video signals are A/D (input) and D/A (output) converted (10-bit). RT-AV110’s high quality analog RCA type connector can be used for NTSC/PAL capture of composite video. Composite supports standard definition video. Simply connect an RCA cable to RT-AV110’s yellow composite RCA connector.
connectors_pack_Analog audio input 3.5mm 2 x Analog stereo audio input on 3.5mm TRS jack:RT-AV100/101 includes dedicated connectors for analog audio capture using 3.5 TRS jack connectors. Use this input when connecting RTAV110 to DVD players, TV’s, etc. Simply connect standard stereo audio cables to RT-AV110’s audio connectors.
connectors_pack_S-PDIF coaxial 2 x S/PDIF coaxial (RCA):Coaxial RCA connector provides access to digital audio. A common use for the S/PDIF interface is to carry compressed digital audio as defined by the standard IEC 61937. This mode is used to connect output of a device such as DVD player to a home-theater receiver that supports Dolby Digital or DTS surround sound. Another common use is to carry uncompressed digital audio from a device such as CD player to a receiver. Simply connect standard digital audio cables to RT-AV110’s RCA audio connector.
connectors_pack_S-PDIF optical 2 x S/PDIF optical (TOSLINK):TOSLINK connector provides access to digital audio. A common use for the S/PDIF interface is to carry compressed digital audio as defined by the standard IEC 61937. This mode is used to connect output of a device such as DVD player to a home-theater receiver that supports Dolby Digital or DTS surround sound. Another common use is to carry uncompressed digital audio from a device such as CD player to a receiver. Simply connect standard digital audio cables to RT-AV110’s TOSLINK audio connector.
connectors_pack_A-V Multi in Multi A/V input (SCART, Component, S-video):RT-AV110 includes Multi AV (Mini Delta Ribbon) for connection with different standard video and audio outputs (SCART, YPbPr, RGB, S-Video, etc.). Besides the capturing of video and audio content, over these specially designed cables (break out cables) we are able to measure some electric values (voltages on SCART pin 8 and 16, etc.). Simply connect break out cables (Figure 2) to the RT-AV100/101’s Multi AV connector.
connectors_pack_LNB in-out F type LNB in/out: F-type connector:RT-AV110 antenna F connectors connect to RF input/output of a STB. That connection enables measurement of some electric values (LNB voltages, loop through voltage, etc.). Simply connect RF input/output of a STB to the RT-AV110 antenna F connectors.
connectors_pack_Ethernet Ethernet connector:Standard RJ-45 LAN connector is used for connecting RT-AV110 to a local network. Ethernet connection is used for either streaming of live video from a capture device in reduced resolution, transferring snapshot frames in original resolution or streaming of audio data captured from any of the audio sources. Besides capturing purposes, Ethernet connection is used for a firmware update of the device, and network configuration (like static IP addresses or usage of the DHCP). Simply connect network cable to RTAV110 dedicated Ethernet connector placed on the back panel.
connectors_pack_Analog audio input 2.5mm 2.5mm stereo jack for remote controller (IR dongle):2.5mm stereo connector is used for connecting IR dongle remote controller emulator (Figure 3). It is a control device used only for transmission of infrared remote commands. Simply connect 2.5mm stereo connector of IR dongle remote controller to RTAV110 dedicated input placed on the back panel.
