* At least 60 channels coming into homes, of which at least 12 would be for public access and municipal uses, such as school programs, televising of government meetings or programs produced by community groups.

* At least 25 channels of a two-way "institutional network" that could be used by hospitals, schools, government agencies and businesses. Individuals probably would be able to link into these channels to get information for a fee.

* At least four channels for residential users to send information, such as for banking, shopping, opinion polling or perhaps voting.

* At least one channel for the hearing-impaired and at least one for the sight-impaired, and an optional visual and aural alarm for the handicapped.

* At least three channels available to be leased by businesses or nonprofit groups, which would decide on programming and could sell ads on those channels.

* An emergency audio override so government officials could make emergency announcements by cable.

* A "lockout" device or code to be provided free to subscribers, so that parents could limit their children's access to certain programs, such as X-rated movies.

* Four studios for individuals and community groups to produce their own programs, under guidelines to be established later.

Bidders could add any other programs or services or capabilities they want to the proposal and could offer sweeteners to the city, such as grants or contributions to public-benefit services.
