从China供应商批发进口8in1 Mpeg-2/H.264 Sd Encoder — FOB条款

The STHD-5708 from Chengdu Sighton Technology is a 1U rackmount encoder that processes eight channels of standard-definition video simultaneously, outputting multiplexed transport streams over both ASI and IP interfaces. Each channel accepts composite video (CVBS) and unbalanced audio inputs, with the unit performing real-time MPEG-2 or H.264 video encoding alongside MPEG-1 Layer II audio encoding. The encoder supports both PAL and NTSC analogue formats, making it suitable for legacy video infrastructure in regions with mixed broadcast standards.

Physical connectivity comprises eight CVBS video inputs (BNC), eight pairs of unbalanced audio inputs, and one ASI input (BNC) for external transport stream multiplexing. Output interfaces include ASI (BNC) and IP (TS over UDP, supporting both multicast and unicast distribution). Control is available via front-panel LCD with keyboard, or remotely through Ethernet-based network management software. The high channel density in a single rack unit is achieved through integrated encoding silicon rather than discrete per-channel modules, which reduces per-channel cost but requires buyers to confirm thermal management in densely packed racks.

Primary applications include cable TV digital head-end systems, satellite digital TV broadcasting uplinks, and terrestrial digital TV transmitter sites. The unit also suits hotel or campus IPTV systems where multiple SD channels must be encoded and streamed to a LAN. Chengdu Sighton Technology positions the STHD-5708 as a cost-sensitive option for budget-conscious operators, though the source description's claim of lowest cost per channel should be validated against specific channel count and licensing requirements. Buyers should confirm with Chengdu Sighton Technology whether MPEG-2 and H.264 licensing fees are included in the hardware price or billed separately.

Chengdu Sighton Technology Co.,Ltd is located in Chengdu, Sichuan Province, China, a city with growing presence in electronics and telecommunications manufacturing though less concentrated than coastal hubs. The trust tier is marked as harbour, with zero response rate and zero average response hours recorded, indicating no response history is available. The supplier address data is minimal, with repeated country entries suggesting incomplete profile verification rather than multiple locations.

The company specialises in broadcast and telecommunications equipment, with this STHD-5708 encoder representing a focused product for digital TV infrastructure. No employee count, factory size, revenue figures, or client references are stated in the source material. The supplier claims cost-effective design and breakthrough pricing, but buyers should request independent verification of these assertions. Chengdu Sighton Technology does not list ISO certification numbers, patent holdings, or R&D staff qualifications in the available data.
