Here is some data on the new XD10 player:
"The DTS XD10 Media Player is a digital playback system used in cinemas that is designed to deliver 10 channels of superior quality digital audio and video for alternate media, and to provide cinema subtitling, closed captions, and narration. It is a dual system with reference to film sound in that the digital audio data is recorded on DVD/CD-ROM discs that are loaded onto a hard drive in the unit. Proprietary DTS timecode is used to synchronize the sound and picture and is printed onto the release print from the soundtrack negative.
DTS timecode assures not only accurate sound and picture synchronization, but is keyed with a unique serial number to assure films are run with the correct digital audio track. To further ensure fail-safe operation, the XD10 performs automatic error detection. If errors are detected, the XD10 automatically pulses the cinema processor to the proper analog sound format. The timecode is printed between the picture and optical sound track The optical sound track is used for backup and is still available for theaters not yet upgrade to DTS digital resulting in a single inventory of prints. When playing DTS formatted film in DTS digital, the XD10 automatically starts; stops, and tracks film breaks and changeovers.
The XD10 provides left, center, right, left-center, right-center, left-back surround, left surround, right-back surround, right surround, and subwoofer channels. The XD10 is capable of playing back DTS digital sound in 5.1, 6.0, 8-track, and 10-track. It must be connected to a cinema processor capable of managing the desired channel configuration.
The XD10 allows for storage of up to 30 complete film sound tracks loaded on its hard drive. Once the hard drive reaches capacity, obsolete titles are easily deleted allowing new titles to be downloaded. After the title information is downloaded, the projectionist may select what playback is desired.
Software updating the XD10 is easily done with a downloadable system disc. Hardware options are available to expand the XD10 functionality: - the addition of video board for the Video Option - the addition a second audio board to expand the number of audio channel outputs to 20 - the addition board for CSP (subtitles/captions) and Narration Options - the addition of an AES/EBU digital output board.
DTS encoded material is available in two digital sound formats: Standard (APTX100) and Coherent Acoustics. - Material recorded in standard digital audio at a 44.1K sample rate with APTX100 digital audio data compression (4:1) providing 8 audio channels plus 2 auxiliary channels. - Material recorded with Coherent Acoustics encoding is scalable, and allows for lossless compression if desired, as well as 96/24. Coherent Acoustics provides for 10 audio channels, plus 2 auxiliary channels. The auxiliary channels will not be phase coherent with the main output channels. The audio used in conjunction with the video will be Coherent Acoustics PCM 48/24 and will be compatible to standard DVD recordings
The XD10’s internal hard drive is used as the film sound signal source and two DVD drives are used to download title/film digital sound information to the hard drive. When DTS cinema discs are placed in the DVD drives, the XD10 automatically downloads the first reel (in approximately 30 seconds). The balance of the reels are then downloaded. The downloading process only needs to be performed once, from that point on, playback is automatic."
Let me know if you have any questions.
