Enhanced trick-play modes for video content that is being streamed to a client from a server are described. In an embodiment, the enhanced trick-play modes are provided with relatively low latency and high quality using trick-play optimization techniques for a streaming environment, avoiding the need to stream the entire contents of the portions through which the viewer is fast forwarding. By employing sophisticated selection criteria of which parts of the content to download at what time, the quality of the playback experience is improved versus that which would conventionally be possible when using a simple sequential frame data download. The streaming client maintains a cache of nearby significant frames, such as nearby key frames, in forward and/or reverse directions of the current playback position, without having to download the entire portions of the video stream in which the significant frames reside. The trick-play modes utilize these frames.

PERFORMING TRICK PLAY FUNCTIONS IN A DIGITAL VIDEO RECORDER WITH EFFICIENT USE OF RESOURCES
Techniques for selecting a picture of a video program for display in accordance with a selected trick play mode of a DVR are described herein. Sometimes, when desired playback speed is faster than normal, a DVR is forced to select some pictures to play and some pictures to skip. Ideally, in order to preserve "smooth" viewing quality, the next picture to be displayed should be temporally close to the currently displayed picture. Since some pictures can take longer to decode than others, accounting for picture decoding costs helps ensure that the best picture can be selected for decoding given playback speed requirements. According to one embodiment of the invention, for each picture of a plurality of pictures in a video data stream, a DVR determines a decoding cost for that picture. Based on the determined costs, the DVR selects a particular picture. The DVR outputs the selected picture for display.
Methods and apparatuses for presenting targeted advertisements to DVR users are described. After a DVR has finished playing a recorded television program, or in response to other specified events, the DVR presents a screen which comprises a "save or delete" menu. In addition to the "save" and "delete" options, the menu additionally comprises other options. Each of these other options may correspond to a separate promotional item. For example, a user's selection of such an option may cause the DVR to display or play an advertisement on the user's television set. Additionally or alternatively, these other options, when selected by a user, may cause the DVR to display a user interface through which the user can actually purchase a product or service. The product or service advertised or offered may be one that was featured or referenced in the television program that the user was just watching.
