Digital media streams are received by a cable set top box (STB 302) from multiple sources, such as cable television and IP (Internet Protocol) sources. The STB includes a standard video tuner and a demodulator/demultiplexer for receiving an encoded media stream from a cable television source. In addition, the STB (Fig.3) includes a modem device and CPU for receiving an encoded media stream from an IP source. The STB further includes a stream selector (304), which selectively receives an encoded media stream from either the video tuner (106) and demodulator/demultiplexer or the modem device (124) and CPU (122), for transmission to a hardware-based decoder (110). |
