A/V Binloop - Frequently Asked Questions

Q Why is my video glitching and/or drifting out of sync with the audio?
A In the Binloop, the audio sample rate of the video file AND the Binloop must match. If they do not, audio does not play at the correct rate. This results in a severe loss of A/V sync, and possibility glitching in the video. The solution is to configure the Binloop to the same sample rate as the video files. All video files must therefore be encoded with the same sample rate.
   
Q Why doesn't the RGB output work with my display? I'm not getting any picture, or the picture is abnormal. 
A Even though the RGB output of the Binloop is an HD-15 connector, it is NOT a VGA output. It is a 480i component video output that operates in one of two colorspace modes: RGsB (RGB /w sync on green) or YPbPr. YPbPr is by far the most common colorspace used in modern displays, and is the 'default' colorspace of the Binloop's component video outputs.
   
Q What is the difference between the Play command and the SPlay (Synchronous Play) command?  
A The simple answer is that 'Play' is not intended for applications where you want to synchronize multiple channels of video. To the Binloop, a 'Play' command means "Play this file as soon as possible". An SPlay means "Play this file at a consistent time after I send the command". For the Video Binloop and Digital Binloop, this consistent amount of time is 16 frames by default. It's important to mention that the 'Play' command that is available for the SMPTE trigger interface of the Binloop Config software is actually an SPlay in disguise.
   
Q I want to play a video with Dolby 5.1 audio. Where does the Binloop output digital audio? 
A The digital audio outputs are available on the connector labeled AES/EBU. Each reproducer has a (-) and a (+) output on this connector. When wiring to a standard RCA coax digital audio cable, the (-) should be wired to the shield and the (+) should be wired to the tip. When playing a video with 2-channel MPEG audio, this output generates a S/PDIF signal. When playing a video with Dolby Digital Audio, the analog outputs of the Binloop are silent and this connector outputs an AC3 signal that must be fed to a Dolby Digital decoder/receiver.  
   
Q What's the best way to control the Binloop using an AMX, Crestron, or other 3rd party control system? 
A Using the Pioneer/AMI ASCII protocol on the 'Show Control' RS-232 port or via Ethernet on UDP port 2638. If you are using RS-232, a NULL cable is required and the settings are 9600-8-n-1. See the Binloop manual for a complete list of commands.
   
Q What's the best way to play 2 or more channels in sync? 
A First, assign the channels to a group using the Binloop Config software or front-panel interface. Name the video files that will be playing in sync with the exact same file number and copy them to each channel's compact flash card. Using either the Serial, Ethernet, or Timecode control interface, send a Synchronous Play command to the group in which the channels are assigned. 
   
Q What's the difference between the Video Binloop and the Digital Binloop?
A There is only one difference, and it is regarding uncompressed audio file playback (WAV, AIF, etc.). The Video Binloop supports uncompressed audio files up to 16-bit 48kHz. The Digital Binloop allows for higher quality playback up to 24-bit 96kHz. Both products are identical in every other way. They both play MPEG2 video, they both support the CobraNet option, etc.
