Abstract
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.
