    摘要： Methods and systems for processing television signals are disclosed herein, and may comprise decoding a first analog video signal via an integrated circuit comprising circuitry for decoding and processing digital video signals. A second analog video signal may be simultaneously decoded via the integrated circuit. A first video output corresponding to the decoded first analog video signal and a second video output corresponding to the decoded second analog video signal may be simultaneously generating via the integrated circuit. An out-of-band signal corresponding to the decoded first or second analog video signal may be received via the integrated circuit. The received out-of-band signal may be processed via the integrated circuit. The first analog video signal and the second analog video signal may comprise an NTSC signal, a composite signal, an S-video signal, and/or a component signal. The digital video signals may be decoded via the integrated circuit.

    摘要： A single integrated circuit is provided to enable the distribution of voice, video, and/or data services throughout a multimedia distribution network, such as a cable communications network. The single integrated circuit supports both digital and analog television services (e.g., PVR, pay-for-view, EPG, e-commerce, etc.) and computer data services (e.g., telephony, Internet browsing, facsimile, messaging, videoconferencing, etc.). In an embodiment, the single integrated circuit includes three components that constitute a DOCSIS™ compliant cable modem, namely a digital inband demodulator, a digital upstream burst modulator, a media access controller, and a microprocessor. In an embodiment, a digital out-of-band demodulator is also included. In another embodiment, the single integrated circuit integrates front-end and backend set-top box functionality in addition to DOCSIS™ cable modem functionality. The set-top box implementation includes at least a front-end transceiver, a backend video decoder, a media access controller, and a microprocessor.
