increasing the video quality, the audio quality or a combination thereof of the select media content based on the selection, while decreasing a video quality, an audio or a combination thereof of the other media content in the digital stream, without exceeding the capacity limit.
17. The machine-readable storage device of claim 16, wherein the increasing of the video quality, the audio quality or a combination thereof of the select media content is based on a reallocation of a resolution of the video quality, the audio quality or a combination thereof of the other media content to the select media content.
18. The machine-readable storage device of claim 16, wherein the select media content and the other media content of the digital stream are provided by a broadcast video service, a cable television system, or a satellite television system.

The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A controlled release security locking arrangement for a manhole cover fit into a manhole opening defined by a surrounding enclosure comprising:
a lock body assembly secured to the underside of the manhole cover adjacent a perimeter of said cover and including a latch slide mounted to said lock body selectively movable radially;
an actuator element drivingly engaged with said latch slide and accessible from the top of said manhole cover to enable outward radial movement of said latch slide to position an outer portion thereof to be engageable with a feature on the inside of said enclosure upon upward movement of said cover to prevent removal of said cover; and
a clearance space between said feature and said outer portion of said latch slide to allow limited rise of said manhole cover to create a gas venting gap around said manhole cover in the event of an explosion;
2. The locking arrangement according to claim 1 further including a controlled release mounting of said lock body assembly allowing movement downwardly of said latch slide portion upon application of an upward force on said manhole cover of a predetermined magnitude to create a greater perimeter gap between said manhole cover and said enclosure allowing a staged increased venting of gases from within said enclosure.
3. The locking arrangement according to claim 1 further including a lug mounted to said cover adjacent said perimeter thereof opposite said lock body assembly and having a portion projecting out radially to be engageable with a feature of said enclosure with upward movement of said cover.
4. The locking arrangement according to claim 3 wherein said latching slide and lug portions are spaced below a point where engagement with said enclosure feature occurs with said manhole cover resting on a seat defined in said enclosure, whereby said manhole cover rises up to a limited extent before said engagement occurs to create a perimeter gap and thereafter preventing further upward movement of said cover, whereby gases can flow out through said perimeter gap to reduce the pressure of gases generated in an explosion acting on said manhole cover.
5. The locking arrangement according to claim 2 wherein said controlled release mounting comprises a pivot pin at one end of said lock body generally opposite said latch slide portion and a shear pin engaging said lock body to normally prevent pivoting down of said lock body about said pivot pin until after said shear pin fails at a predetermined upward force exerted on said manhole cover.
6. The locking arrangement according to claim 4 further including a stop limiting said downward pivoting movement of said lock body assembly upon failure of said shear pin so as to allow reengagement of said latch slide portion with said enclosure feature with further lifting of said manhole cover to create a greater perimeter gap through which gases can be vented.
7. The locking arrangement according to claim 6 wherein said stop comprises a secondary shear pin failing at a predetermined upward force exerted thereon by said manhole cover during an explosion in said enclosure to allow free pivoting down of said lock body to an extent allowing said manhole cover to be blown completely free of said enclosure.
8. The locking arrangement according to claim 1 wherein said manhole cover has a perimeter skirt depending from the inside thereof, with a series of scalloped slots contoured to redirect the flow of gases downwardly towards said gap to retard inflow of air in an explosion.
9. The locking arrangement according to claim 1 wherein said actuator element comprises a bolt received in a threaded bore and having an end engaging a cam surface on said latch slide to cause movement in a radially outward direction upon advance of said bolt in said threaded bore.
10. The locking arrangement according to claim 9 wherein said bolt has a head accessible from the top within an opening in said manhole cover.
11. The locking arrangement according to claim 6 wherein a pair of ribs extends across said manhole cover on the underside thereof to stiffen said manhole cover and said lock body is pivotally mounted between said ribs.
12. The locking arrangement according to claim 7 wherein successive slots are canted radially in opposite directions an angle of about 30\xb0-45\xb0.
13. The locking arrangement according to claim 7 wherein said slots are angled downwardly an angle of about 30\xb0-45\xb0.
14. The locking arrangement according to claim 5 wherein a pair of retainer plates are removably attached to the underside of said cover and said lock body assembly to pivotally mounted between said retainer plates.
