GV7704-IBE3

The GV7704 is a quad channel serial digital video receiver for High Definition component video. With integrated high performance cable equalizer technology, the GV7704 is capable of receiving compressed video at 270Mb/s or 540Mb/s, or uncompressed at 1.485Gb/s or 2.97Gb/s, over 75O coaxial cable, or differentially over a 100O twisted pair cable.The GV7704 integrates the High Definition Visually Lossless CODEC (HD-VLC) technology, which has been developed specifically to reduce the transmission data rate of HD video over both coaxial and unshielded twisted pair (UTP) cable. This is achieved by encoding the HD video, normally transmitted at a serial data rate of 1.485Gb/s, to the same rate as Standard Definition (SD) video, at 270Mb/s serial data rate.At 270Mb/s, the effect of cable loss is greatly reduced, resulting in much longer cable transmission. For 75O coaxial cable, cable reach can be extended up to 3x the normal reach when transmitting encoded HD at 270Mb/s. In typical video over coaxial installations, cable distances of up to 550m are possible. Similarly, a 2.97Gb/s 3G signal can be transmitted at 540Mb/s using HD-VLC.The GV7704 can also be configured to receive HD and 3G video over UTP cable, such as Cat-5e and Cat-6 cable, when HD-VLC encoded at 270Mb/s and 540Mb/s, respectively.The device supports the reception of both 8-bit and 10-bit per pixel YCbCr 4:2:2 BT.1120 component digital video.The GV7704 supports direct interfacing of HD video formats conforming to ITU-R BT.709 and BT.1120-6 for 1125-line formats, and SMPTE ST 296 for 750-line formats.The GV7704 supports the extraction of ancillary data from the horizontal blanking of the input video data stream. The GV7704 recognizes data packets formatted in compliance with the HDcctv 2.0 communications protocol.The GV7704 features an audio de-embedding core, which provides the extraction of up to 4 channels of I2S serial digital audio from the ancillary data space of the input video data stream.Packaged
