Overview

From four (4) to eight (8) VDC cards can be inserted into a 1U server, depending on the server motherboard and chassis design

The Video Content Delivery card (VDC card) provides high capacity video content processing for x86 based servers. The VDC card is a half-length, single-slot width, full-height card, which -- combined with the card's low power consumption of less than 50W -- allows up to 8 cards in a 1U server depending on the server motherboard, riser card, and chassis design. For example in Signalogic's lab, we are developing a video content delivery server that uses a Supermicro motherboard and chassis to run 4 cards (see picture at right).

The VDC card provides both (i) basic API functions including video transcoding, conferencing, audio codecs, and encryption, and also (ii) user-defined functions implemented as OpenMP marked acceleration of arbitrary C/C++ source code sections. A list of supported functions is given below.

The acceleration capability is supported by CIM software, which includes resource management to efficiently allocate API functions and concurrent threads to the 32 cores. Combining CIM acceleration with user-callable APIs gives the VDC card greater flexibility. Additional advantages of this approach include:

• Compatibility with existing x86 implementations (i.e. avoiding time and expense of porting to an API based approach)
• Reduced long-term maintenance
• Open source standards compliance
• From a programming perspective, viewing all cores in the server -- both x86 and CIM -- as similar; i.e. a truly heterogeneous CPU architecture. This avoids changes in standard Linux based code development and maintains consistent day-to-day build procedures

The 1 GbE network interface on the VDC card supports IP/UDP/RTP streaming and is visible to all 32 cores on the card.

The VDC card is supported by SigIMS software, an extension of Kamailio (OpenSER) and rtpproxy.

H.264 SD (or 4CIF), 30 fps	2	B

NOTES

¹ 32 cores total for one card (8 cores per CPU, 4 CPUs per card). Number of cards in a server depends on several factors, including server enclosure / form-factor, type of PCIe slots, and power supply capacity.

Tech Support

Signalogic's engineering staff maintains, operates, and tests the Video Content Delivery card in the company's in-house lab. Customers can submit technical questions via e-mail, phone, or Skype chat.

Signalogic engineers are experts in server-based and embedded system development. Unlike retailers and distributors who offer video-related products, Signalogic performs contract development using video delivery devices, and uses these devices in the company's in-house labs on an everyday basis. Also Signalogic is a member of TI's third-party developer's program. This level of tech support is a distinct advantage of purchasing video content delivery products from Signalogic.
