Abstract: A video streamer aggregates multiple videos into a single video stream for delivery to a client to be displayed. The multiple videos are active to allow motion of the multiple videos to be shown. The multiple videos are part of an electronic program guide. Additional information related to one or more of the videos may be obtained and displayed by the client. One of the videos may be selected to be enlarged and/or have audio from that video played.

Abstract: In some embodiments, a video (e.g. MPEG-2, H.264) transcoder channel pool is used to transcode multiple independent videos (programs) per channel substantially concurrently. A syntactically-unified combined input video stream is assembled by interleaving segments of different input video streams. The combined stream may be a container stream or elementary stream. Each segment includes one or more groups of pictures (GOP). The combined stream includes the payload video data of the input streams in unmodified form, and modified header data characterizing the combined stream as a single video stream. The combined input stream is transcoded using a single transcoder channel/input port to generate a combined output video stream. Multiple independent output video streams are assembled by de-interleaving segments of the combined output video stream according to stored interleaving break identifiers.

Abstract: In some embodiments, a server system composites in real-time, in response to a user video search query, a standard-compliant (e.g. MPEG-4/H.264) SD or HD video stream encoding a rectangular (x-y) composite video preview panel array (grid) of video search results. Each panel/tile in the rectangular panel array displays a temporal section (e.g. the first 90 seconds, looped-back) of a video identified in response to the user query. Generating the composite video panel array in real-time is achieved by compositing the component video panels in the compressed domain, after each panel undergoes a compressed-domain pre-compositing preparation process that facilitates dynamic compositing of the panels into a single video stream. The pre-compositing preparation includes transcoding to a format having a down-scaled common resolution, common GOP structure, and one-slice-per-row slice structure.
