A television set top box (100) includes an A0 interface (110), such as DAVIC (Digital Audio Visual Counsel), which is internally coupled to dual Segmentation and Reassembly (SAR) controllers (113). Within the A0 interface (110), the set top box (100) includes an internal connector and internal Network Interface Module (NIM) (111). An External Reader is affixed to the set top box (100) for reading signals from an external security device, such as an iButton. The set top box (100) also supports IrDA (Infrared Data Association), an infrared based communications protocol, as well as CE (Consumer Electronics)-BUS for household electronics control. The set top box (100) further includes a dedicated infrared (I/R) processor to reduce the functions of a primary processor in the set top box (100). In addition, the set top box (100) includes karaoke input jacks for mixing singers with music. |
