◆ MPEG2 4:2:0/4:2:2 and H.264 4:2:0 encoding ◆ MPEG-1 Layer II, HE-AAC(v1&v2),LC-AAC and AC3 pass-through (for SDI in only) ◆ 2 stereo or 4 mono audio channels ◆ Low latency encoding mode, closed caption support ◆ HD and SD downscale
Overview
ENC3411 has proven itself as the most advanced encoding platform for TV Studio Station,Cable, Satellite, IPTV, Terrestrial or ISDB-Tb applications available today. The hardware platform has been widely deployed for MPEG-2 and MPEG-4 AVC HD broadcasting applications with Two pairs of Audio inputs. The significant advantage in Picture In Picture(PIP) and DVB-ASI Multiplexing. For telcos and other IP-based service providers, the encoder is highly bandwidth efficient MPEG-4 CBR encoding and native IP output make it possible to deliver exciting and competitive HD services. Espically use in Multi-Audio channel MPEG-2 HD 4:2:2 in High-End Cable TV and ISDB-Tb Application.
ENC3411 is the industry’s HD encoder based on ASIC processing technology and provides full 20-30% compression gain over the first generation of DSP-based MPEG-4 HD encoders. Additionally, embedded audio as well as support of closed captions transferred in the HD-SDI and CVBS means efficient routing and simpler back-up system designs. Further more, to the encoding format 4:2:0, also supports 4:2:2 encoding for single channel encoding in contribution applications,
Low resolution outputs – is apable of simultaneously delivering low resolution channels for new applications such as picture-Inpicture (PIP) and ISDB-Tb One Seg application
Native audio encoding – Up to 2 stereo pairs of audio encoding are supported, in formats such as MPEG-1 Layer II, HE-AAC(v1&v2), LC-AAC and AC3 passthrough ( SDI in only) in ultra low bitrate encoding
