How to use a Motorola DVR
Motorola Customer Premises Equipment (Set-Tops)
About 80% of Comcast's systems are Motorola based.
There are a few series of Motorola set tops.
The low-end Motorola 68k models include the DCT-1700, 1800, and 2000. Due to the limited memory and processing power, these models have a reduction in amount of guide data that is stored in memory. While they can still support simple ITV applications, the local area will need to employ guide filters to these set tops that prevent them from loading a full set of guide listings. Also ITV transparency elements are not available, as well as video scaling. The general performance (navigation and channel changing) is much slower. These set tops are SD capable ONLY. Back in the early days of HD, a Motorola HDD-200 sidecar box could be connected to the data port on DCT-2000's to enable HD decoding.
The mid-range Motorola MIPS-32 models include the DCT-2500, DCT-700, DCH-70, DCH-100, DCH-200. These models are noticeably faster than the older 68k models. They support video scaling, which means you will see the current channel scaled down to fit in the upper right corner of the guide. These set tops are SD capable ONLY.
The high-end Motorola MIPS-64 models encompass a larger subset of equipment:
DCT-5100 Original HD cable box (DVI Interface)
DCT-6200 Widely used HD cable box (DVI Interface)
DCT-6208 Single Tuner HD DVR (DVI Interface) (80GB)
DCT-6412/6416 Dual Tuner HD DVR (DVI Interface, except for Phase 3 revision which has HDMI) (120GB/160GB)
DCT-3412/3416 digital-only Dual Tuner HD DVR with HDMI (120GB/160GB)
DCH-6412/6416 CableCARD Dual Tuner HD DVR with HDMI (120GB/160GB)
DCH-3412/3416 CableCARD digital-only Dual Tuner Cablecard DVR HD DVR with HDMI (120GB/160GB)
DCX-100 MPEG4 compatible SD digital-only cable box with 1GHz tuning (M Models support MoCA) and CableCARD
DCX-700 Small Form Factor MPEG4 compatible HD digital-only box with 1GHz tuning (M Models support MoCA) and CableCARD
DCX-3200 MPEG4 compatible HD digital-only box with 1GHz tuning (M Models support MoCA) and CableCARD
DCX-3400 MPEG4 compatible digital-only dual-tuner HD DVR with 1GHz tuning (M Models support MoCA) and CableCARD
DCX-3501 (AKA RNG200N) MPEG4 compatible digital-only dual-tuner HD DVR with 1GHz tuning (M Models support MoCA) and CableCARD
The latest DCX models have the most available memory and processing and can be configured with as much as 512MB RAM, and 500GB Hard Drive (DCX-3501). The DCX-3x00 series also allows native HD resolution pass-through, video sharpness post processing, and can decode Dolby Digital Plus. The DCX models also run much cooler than their DCH / DCT cousins. All i-Guide and Interactive TV features will work on the MIPS-64 based boxes.
The Motorola naming scheme is as follows:
DCT series - integrated security (no CableCARD slot)
DCH series - separable security (CableCARD pre-installed)
DCX series - separable security (CableCARD pre-installed), Advanced functions (Processor, Memory, MoCA, MPEG4, Dolby Digital Plus, 1GHz Tuning)
QIP series - integrated security (no CableCARD slot), similar to DCX series with MoCA and IPTV functionality paired with traditional QAM tuning. This series is only used for Verizon FIOS.
