Enrique Rodriguez, the Microsoft Corp. (Nasdaq: MSFT) exec who joined Cisco Systems Inc. (Nasdaq: CSCO) in 2010 to lead the launch of Videoscape, has resigned, Light Reading Cable has learned.

Cisco didn't give a reason for Rodriquez's departure, which was announced internally on Monday, but multiple sources say he left on his own accord. One industry source said Rodriguez opted to leave amid a power struggle centered on the future direction of Cisco's video division.

Cisco did confirm that it has combined its service provider and enterprise video business under the leadership of Marthin De Beer, the SVP of Cisco's Emerging Business Group.

"We believe this move will spur innovation and synergies across Cisco's end-to-end video portfolio, which spans service provider, enterprise and consumer networks, and enable Cisco and our customers to introduce compelling new video services, applications and experiences with speed and agility," Cisco said, in a statement.

De Beer will also serve as acting GM for Cisco's Service Provider Video Technology Group (SPVTG) as the company seeks Rodriquez's replacement. His successor is expected to report to De Beer.

Rodriguez, who previously handled Microsoft projects such as Mediaroom and Zune, joined Cisco in May 2010 as SVP and GM of Cisco's SPVTG. In January at the Consumer Electronics Show, Cisco unveiled Videoscape, an architecture designed to help MSOs and other service providers deliver video services to TVs, PCs, smartphones, tablets and other IP-connected devices.

It's been trying to win deployments and fleshing out components for it ever since, also viewing Videoscape as another way to help drive set-top sales. In February, Rodriquez identified 2013 as the anticipated "sweet spot" for Videoscape deployments.

Cisco says Rodriguez's departure has no bearing on the company's continued focus on video. (See Chambers Promises a Simpler Cisco.)

"Our commitment to Videoscape doesn't change," the official said.

It's believed that Rodriguez's departure is not directly connected to a broader Cisco reorganization that's resulting in the laying off of 6,500 employees and the sale of its set-top plant in Juarez, Mexico.
