CableWorld MPEG-4 Encoder CW-4411/4412
The MPEG-4 Encoder receives at its input the video signal and the accompanying audio signal, performs their compression according to the H.264 standard and outputs them in SPTS (Single Program Transport Stream) form over both ASI and IP output. The output transport stream includes the most important PSI/SI tables (PAT, PMT, SDT, NIT), thus in simpler systems the encoder can be applied even without using a remultiplexer. The device can receive multiple analogue and digital signal formats: CVBS or S-Video, YPrPb as well as HDMI and SDI.
Baseband analogue video signals (CVBS/S-Video, YPbPr) and uncompressed digital video signals (SDI, HD-SDI, HDMI) have to be digitalized and compressed in order to make them appropriate for digital video broadcasting.
The device processes both analogue and digital video sources, encodes them according to the standard H.264/MPEG-4 AVC, and forwards the 188-byte transport stream packets embedded in UDP/IP or RTP/IP packets through IP network as single-program transport streams. These single-program transport streams are available at the ASI (Asynchronous Serial Interface) outputs, too.
The supported video formats are 1080i, 720p, 576i and 480i with 50, 59.94, and 60 Hz refresh rates. High-resoluton sources can be downscaled to standard-resoluton ones in order to reduce the output data rate. Additonally, standard-resoluton sources can be converted to 96×96 or 128×96 pixel thumbnails for picture-in-picture (PiP) applicatons.
– Analogue video inputs: CVBS or S-Video and YPrPb
– Processing and inserting the data of the vertical blanking interval of the CVBS signal (teletext, VPS, WSS etc.)
– Analogue audio inputs: two-channel asymmetrical or two-channel symmetrical
– Digital audio inputs: HDMI, SD/HD-SDI (with embedded audio)
– One or two double ASI outputs and/or common unicast/multicast IP output
– One or two independent MPEG-4 encoders with SPTS output
– Ten parameter sets (default settings) with one-button selection, with individual modification possibility
– SD (720 × 576 50i, 720 × 480 60i) and HD resolution (max. 1920 × 1080 50i, 1920 × 1080 60i)
– Resolution conversion from HD to SD
– Automatic 100Base-T and 1000Base-T network recognition and display, full-duplex mode
