Methods and systems provide synchronized sharing of multimedia between multiple devices. The multiple devices may form an ad-hoc network for sharing of multimedia. In an embodiment, group members may have playlist manipulation privileges such as pausing, rewinding, fast forwarding, or adding tracks to the playlist. A system may stream or distribute content according to the shared playlist. Playback may be synchronized for group members so that everyone is exposed to a same part of the content as the same time.

Synchronized playback and control of media

Methods and systems provide for coordinated control between multiple devices of playback of a media track or playlist. The multiple devices may form an ad-hoc network for sharing control of media. A control device may coordinate control of the playlist and facilitate playback of the media at a playback device. Then when the control device leaves the group, a second device in the group will seamlessly become the control device and control playback and playlist coordination. The playback device may also be the control device. The playback advice may be a network-enabled speaker. Where the playback device is separate from the control device, the playback device may maintain sufficient information to operate without a control device until a new control device is selected.

Coordinated control of media playback

A method and apparatus for rendering using band by band depth adjustment preferably begins by recording extents for each object on a page. An extent indicates where color or non-color ink begins and ends on a page. Extent blocks are then created. An extent block is comprised of at least one extent of the same ink type. Next, a band is created for each extent block. The bit depth for each band is adjusted based upon the ink type associated with each extent block. If the ink is black or white, a band having a bit depth of one is created. If the ink is color or gray scale, the bit depth is adjusted to the proper depth for that band. An object or portion of an object is then rendered into a band having the necessary bit depth for that object.
