Home cinema system devices
A television and a home cinema device work together in various embodiments to render an audio signal including at least a left channel, a right channel and a center channel. The left and right channels are rendered by left and right speakers coupled to the home cinema device, while the center channel is rendered by the left and right speakers of the television. The television can receive the audio signal, decode and render the center channel and send the audio, possibly reencoded left and right channels, to the home cinema device. The television can also send the audio to the home cinema device the returns the, possibly reencoded, center channel for rendering on the television. Alternatively, the home cinema device can receive the audio signal and provide the possibly reencoded center channel to the television. In an alternative, the center channel can be rendered by a soundbar coupled to the television.
1. A television configured for connection to a sound rendering device, the television comprising:
a decoder configured to:
decode a first audio signal comprising at least a left channel, a right channel and a center channel; and
provide a decoded center channel for rendering on first speakers; and
an encoder for encoding a decoded left channel and a decoded right channel to obtain a second audio signal for output to the sound rendering device for rendering sound on second speakers.
2. The television of claim 1 , further comprising a digital sound processor unit for sound processing of audio channels to be provided to the first speakers.
3. The television of claim 1 , wherein the first speakers comprise internal left and right speakers of the television.
