    • A system that incorporates teachings of the present disclosure may include, for example, a system having a controller that increasing a first quality of first media content to achieve an adjusted quality, by adjusting a number of first encoded video portions, first encoded audio portions or both allocated to a presentation of first video and first audio of the first media content. A digital stream having a total bandwidth includes the first media content and second media content. A second quality of the second media content is decreased, by decreasing a number of encoded video portions, encoded audio portions or both allocated to a presentation of second video and second audio of the second media content, while maintaining consistency in the total bandwidth of the digital stream. Other embodiments are disclosed.

    • A system that incorporates teachings of the present disclosure may include, for example, a system having a controller that receives an indication of a resolution preference for presenting first media content received in a digital stream, wherein the digital stream comprises the first media content and second media content, and wherein the digital stream has a bandwidth limit. The controller, responsive to receiving the first media content adjusts a first resolution of the first media content to achieve an adjusted resolution. The controller also adjusts a second resolution of the second media content to offset, at least in part, the adjusted resolution, wherein the first resolution and the second resolution are adjusted without exceeding the bandwidth limit of the digital stream. Other embodiments are disclosed.
