FREQUENTLY ASKED QUESTIONS
Q: Is there an HD-SDI video output of the Motorola Satellite Receivers with embedded audio?
Q: Can we have additional splicers?
A. Additional splicers will be made available for the station to purchase. In some cases, a "Zone Splicer" can be provided (an alterative to a complete Splicer Rack Insert) to feed either a 'satellite' transmitter (hyphenated markets) or to provide 'zone' feeds to a cable head end. Stations should first contact their Affiliate Relations representative for further details.
Q: Will the Network provide AFD flags on the network HD stream?
A. The FOX Network is currently inserting AFD (Automatic Format Descriptor) codes (Both 1010 and 1011) into the HD video stream. The AFD is used to determine the type of formatting for the SD downconvert, either 'letterbox' or 'center cut'.
Q: Will there be a way to connect the new Cisco 24 port switch to our Local Area Network (LAN)?
A. The DSR 6000 Satellite radios do not have an HD-SDI output. However USSI should have connected the Tandberg TT1280 receiver/decoder to the C receiver. This provides baseband decoding to 720p59.94 and has both embedded audio and AES audio. This output can be utilized for non-programmatic feeds (promos, news cut ins, etc). Affiliates can also supply their own decoder/downconverter or alternatively provide a downconverter.
A. The access to the FOX Ethernet Switches is strictly limited to specific functionalities. The unused ports are locked down. The FOX Ethernet Switches should not be connected to your internal LAN systems. The connections that will be allowed are:
(2) connections for the IP decoders used to preview the FOX Net Signal
(2) connections to the ROSA PC supplied by FOX.
(1) EAS/Weather alert interface for sending alert messages and graphic files to the Cisco DCM6000's.
(1) Gig E connection to the C receiver for delivery of promo files.
Q: Can I use the extra RF ports?
A. Yes, there are (8) outs for every input. FOX will be using (4) outputs and reserves (1) output, thus a total of (5) outputs/input. Therefore, (3) outputs remain available for station use. They provide unity gain. Please do not connect 18 VDC to the F-connectors. While we have DC blocked on the outputs, why stress the system?
Q: Can I have more than one HD service through the splicer?
A. While the splicer is capable of passing multiple program streams, the ATSC bit rate of 19.39Mb/s cannot support more than one HD program.
Q: Since the Cisco Splicing System will generate the PSIP tables, how is this going interact with our current PSIP system? We have the Triveni GuideBuilder for our primary. Other stations are using the Thales Pearl, DTV Innovations and others?
A. The DCM9000 will capture the local PSIP tables, store them, and then carousel them on the output side. This is how the Thales Pearl operates as well as some Triveni Guidebuilder systems. The PSIP_Update process will update the tables as cached in the DCM9000 Splicer, based on the information in the PSIP_Update message (Content Advisory, rc_descriptor, cc info). These messages will only affect network programs. In summary the PSIP output of the DCM9000 should appear the same as the input PSIP along with the network updates, if present.
Q: You specify (2) 20A services in the Fox Rack? I have one circuit feeding the rack as originally required which I feed a Powerware 2000 W UPS (I removed the Liebert 1,00W UPS as it didn't have enough to power the rack after adding the Fox I-Pump and 4th receiver). Are you just referring to the 2 power strips feeding off the back of the UPS?
A. The calculated load of the receiver insert and the Splicer insert is close to 1600 watts. Using a single 20 amp service, and rating a circuit breaker for 80% continuous load equates to 1920 watts. While one 20 amp circuit is mathematically sufficient, two allows a greater margin during the extremely rare full power up condition.
Q: We are only feeding one ASI stream from master control for HD and SD to the rack. Is this what is referred to as MUX A?
A. Yes. If you only have a 'single thread' DTV chain, we will employ the Grass Valley ASI DA's to provide the additional copies.
Q: How do we add a secondary DTV channel into our local multiplex?
A. It will be helpful to write down all the program information (PMT PID value, Video PID value, Audio PID values, Virtual Channel, etc). Contact email@example.com and indicate you want to add a secondary channel. FYI, in order to fit the SD in your multiplex, the video bit rate should be 3.5Mb/s or less. We suggest using 540x480 or 480x480 resolution. The FOX HD program allows for up to (2) SD channels during prime time programming but during sports programming only (1) SD.
Q: Why can't we upload our logo or download software updates from the FOX ftp site?
A. The process has been simplified. Send a properly named .png file to firstname.lastname@example.org. The .bmp graphics format is no longer in use. Make sure to identify if the submitted logo is a Branding logo (bug) or a Legal ID. For complete logo instructions, see the tab at the top of this page or go here.
