SLING MEDIA, INC., Foster City, CA 2008 – Present

Senior Software Engineer (Embedded Software group) Key Projects:

• Brought up system hardware and adapted u-boot on custom made board based on ARM processor TI OMAP 4470. Update firmware (used AAdvark over I2C). Write test utilities to read data from devices on board (GPS, Accelerometer) over I2C bus.

• Brought up custom-made board based on xc4200 (multimedia processor has main MIPS processor and two ARC 750D processors all simultaneously running their own real time operating systems).

• Developed and optimized Sling player for system with ARM/MIPS processors based on Roku NDK.

• Executed implementation of CVP-2 (new DLNA standard) in SlingBox.,Developed and supported STB simulator to run load test for Dish Remote Access. Developed and supported a part of the DRA (Dish Remote Access) project. Implemented synchronization via MySQL. Integrated SlingBox technology into new EchoStar STB

(worked on new API, ported part of existing gcode from SlingBox system to EchoStar Boxes) to make it more compatible to a new environment.

• Performed combining EchoStar 922S STB and Sling Media (Da Vinci TI chip) technology. Sling box connected with main board by RS232 and TSI (Transport Stream Interface). Uboot loaded on to Sling box over RS233 and after booting, the rest of the firmware is loaded over TSI (Transport Stream Interface). Accomplishments:

• Created first generation of product allowing consumers to access programs available on their home TVs from PCs or cell phones. (Best Product in Home Video category at Consumer Electronics Show 2009).

• Developed and deployed the prototype server for supporting Real Time Messaging Protocol (RTMP) that enables viewing of prerecorded HD content over LAN on any home device using Macromedia Flash Player. VADIM GRIGORIEV 916-***-**** actpnu@r.postjobfree.com
