Due to an editing error, an article in Sunday's editions of The Post gave the wrong name for an executive of the Arlington TeleCommunications Corp. His name is John D. Evans.

Starting Wednesday, some Arlington television viewers may curl up on the living room sofa to watch the Atlanta Braves play baseball - on an Atlanta TV station.

On subsequent days, they can also watch a premiere movie called "Embryo" starring Rock Hudson, or check up on the weather forecast, or compare grocery prices in the local supermarkets.

These and other services are part of a new 32-channel television system, the first major system in the metropolitan area, scheduled for inauguration Tuesday.

Officials of Arlington Telecommunications Corp. (ARTEC), which owns the $7 million system, said between 10 to 15 miles of Cable will be in place on utility poles in the Clarendon and Lyon Village areas of Arlington by that time.

About 30 homes have signed up for the service, they said.

John D. Davis. ARTEC's chief operating officer, said that the county-wide network of cable - 360 miles of it - will be completed in 18 to 20 months.

Cable television, which transmits pictures by coaxial cable instead of between antennas, was originally popular in rural areas that had poor reception. In recent years, however, it has started to appear in urban areas because it can offer clear pictures and special services such as sports events and first-run movies without commercial interruption.

ARTEC's Metrocable service will provide subscribers with all Washington commercial stations. All Baltimore commercial stations, four educational stations, Atlanta's WTCG owned by Atlanta Braves owner Ted Turner, a family channel including religious programming and events from Madison Square Garden, and automated information channels including radar weather and a local comparative shopping guide. It also includes Home Box Office, which provides until movies and sports events without commericals.

ATREC also provides two channels for the county government, four for the county schools and one for the public.

This premium service costs $16.90 a month, but county residents may also subscribe to the Metrocable II service, which does not include the Home Box Office features, for $7.95. The installation charge is $14.95.

The push for cable television began more than eight years ago in Arlington when the county received authority from the General Assembly to grant franchises for the service. The County Board approved a cable television ordinance in 1971 and selected ARTEC from a field of five applicants to install the system in 1973. The Federal Communications Commission approved ARTEC's application in 1975.

Under terms of the ordinance the service was supposed to begin within two years of FCC approval, but ARTEC ran into problems financing its operation and received an extension until Tuesday to begin service.

Reston and Gaithersburg each have cable television systems, but they are smaller systems than the one planned for Arlington.

Alexandria, which once shelved the idea of cable television, adopted an ordinance last month and is expected to award a franchise within six to eight months.

Montgomery County has been wrestling with the idea for several years and has scheduled another meeting on a cable television bill in August. Prince George's County has adopted a cable television ordinance and expects to award a franchise in about a year.

In the District prospects of a cable system have been slowed by the expense involved in putting the cables underground. The council has considered a bill, however, that would authorize a franchise operation and is expected to take final action on it this fall.
