Techlogg: Chip vendor Intel has moved another step forward in its bid to grab some of the lucrative consumer electronics market for digital TV devices with the release of its first dual digital TV demodulator chip.
The chip can extract audio and video data from two digital TV channels at the same time and is expect to see use in a range of devices from personal video recorders (PVRs) through to integrated digital televisions as well as PC-based TV tuner cards.
It will enable users to watch one digital TV channel while recording another. The integration of two demodulators onto the one chip means consumer electronics device manufacturers will be able to make smaller products and due to the new chips’ low power consumption, portable handheld devices are not out of the question.
The CE 6250 dual-channel demodulator and the higher-performance CE 6251 diversity-enabled dual-channel demodulator chips consume less than 280-milliwatts (280mW) of power during standard operation. The CE 6251’s diversity function allows it to use two antennas to better pick out the broadcast signal from a digital TV station.
