What is a Digital TV Tuner DVR Cable Box?
advanced menu systems, and high definition channel tuning through the Set Top Box. Though virtually all digital televisions have their own high definition, built-in tuners these days, an HD, set-top box is a more powerful way to tap into your TV’s features and performance, such as Digital Video Recording (DVR). Cable Companies such as Comcast, have an additional feature called, Video On-Demand which allows you to choose from hundreds of programs or movies and watch them when you want to watch them. You will need a set-top box to do this.
The DCT6412 is a Dual-Tuner DVR High Definition Set-top box by Motorola.
Setup of the DCT6412 DVR Cable Box
In order to take full advantage of the features and get the most of the picture and sound quality of the DCT6412 Dual Tuner DVR Cable Box along with your home theatre sound system, you will need either a set of component video cables or HDMI cable, and a digital audio cable. Setup is pretty straight forward. There is only one Coax Input on the back of the DCT6412 Dual Tuner Set Top Box. That is where you will connect the cable coming from your house. Next, you will need to hook the necessary video and audio cables from your DCT6412 Set Top Box to your television and/or stereo system. The HDMI or Component Cables (either of these are sufficient for High Definition Display), plug into the respective video out connectors on the back of the cable box, than to the HDMI or Component in of your television. The HDMI is the preferred cable merely for the fact it is smaller, less bulky and has only one connection. For audio, the Set Top box includes a couple of RCA jacks. Plug the two RCA Audio connectors to the back of your box, then to the audio input jacks of your television. You are now ready to watch and listen to your television without the use of your stereo or home theatre system. If you are going to be using your television as part of a home theatre system, you may still want to have your set top box audio connected directly to the television so you can simply watch the TV without always having to turn on the surround sound. The DCT6412 Cable Box has Optical Audio outputs. Plug your Optical Cable into this and then into one of the inputs of your Surround Sound Receiver. This will allow you to listen to movies or music which are programmed and transmitted in Dolby 5.1 Surround Sound. One other convenient feature is that the front of the unit has a set of video/audio RCA inputs. These can be used for displaying output from an external device such as a camcorder. That is pretty much it for the basic setup of your DCT6412 Cable Box. There are a number of other interesting connections on the unit, but any explanation of what they are for and how they are used is inexplicably absent from any of Motorola’s manuals or documentation. For instance, there are two USB connections; one in front and one in back. There is one firewire connector and one 10/100 Ethernet jack. Also, there is a smart-card slot, which is used by your cable provider for programming your service. I have done some research online and will report on what these mysterious, unknown, undocumented features can and cannot be used for in an upcoming article. Meanwhile, let’s discuss how it all works:
Basic Operation of the DCT6412
The DCT6412 Remote can be programmed to control your Television, DVD or VCR player and your Audio System. Instructions are included for how to do this. I’ve found that the number or channel buttons on the remote are a little bit small and awkard to control; otherwise the remote is adequate and easy enough to learn and use. Press the TV button on the remote, then press the cable button to power on the cable box and change channels on your box. When your Cable box is plugged in for the first time, it will take several minutes for it to find and program all of the station information. Once this is completed, you can view detailed information on any program you are watching by pressing the ‘info’ button. You can use the channel up-down button to change programs, or you can press the ‘okay’ button in the center of the four arrows which are located in the middle of the remote. Pressing the ‘okay’ button makes it possible to browse and scroll through 3 or more channels at a time. When you find the program you want, simply select ‘okay’ once again. You can actually scroll ahead several days in advance to view the programming of any channel you are browsing. If you want a full-screen view of television programming, press the ‘guide’ button. You can press the ‘menu’ button to do a search for your favorite program by category or title. There are also a number of other features that can be setup through the ‘menu’ function: Basic Setup, On-Demand, TV Listings, Search, Parental Control, DVR, Messages, Local Weather, Help, and Pay-Per-View. Each of these menu settings are described in detail in the included DCT6412 user manual. The DCT6412 will support all of the common digital television resolutions; 480i, 480p, 1080i and 720p. There is also a stretch mode which automatically stretches a standard definition program picture to fill the screen of a wide format television. The resolutions you choose depend on the capabilities of your television resolutions, so make sure you know what your TV supports. Note: The box gets very warm. The manual recommends placing it in a well ventilated area: Good advice.
DVR: Digital Video Recording on the DCT6412
Video-On-Demand on the DCT6412
If you want to watch Video On-Demand, press the VOD button. A menu appears with categories such as, Top Picks, Movies & Events, HD On-Demand, TV Entertainment, TV Series, Free Movies, Sports, etc. etc. Comcast advertises that there are thousands of On Demand choices. I have never counted them all, so I’ll take their word for it. The REW, FWD, PAUSE, STOP all work very much the same as the DVR menu. This is one weakness I’ve come to realize about the DCT6412: The interactive response time is very slow. For example, if you want to fast-forward to your favorite scene of a movie or football game, it is a difficult and very slow process getting there. One solution is to use the DVR to record the show first. Navigating a pre-recorded program is much easier and faster.
