摘要:
A system and method for providing multiple video presentations per audio program. In one aspect, the method comprises (a) assigning a first packet identifier (PID) to a first elementary stream, wherein the first elementary stream comprises video packets corresponding to a high-definition video presentation; (b) assigning a second PID to a second elementary stream, wherein the second elementary stream comprises video packets corresponding to a standard-definition video presentation and the second PID is different than the first PID; (c) assigning a third PID to a third elementary stream, wherein the third elementary stream comprises audio packets corresponding to a selected audio recording, wherein the third PID is different than the second PID; and (d) (1) creating a program map table that includes the first PID, the second PID and the third PID or (2) creating (i) a first program map table that includes the first PID and the third PID and (ii) a second program map table that includes the second PID and the third PID. In this way, the method provides a high-definition and a standard-definition video presentation per a single audio program.
摘要:
A system and method for purchasing broadcast audio and/or video (audio/video) works. According to one embodiment, the system includes a data stream processor that receives a broadcast audio/video data stream and produces from the broadcast audio/video data stream a first audio/video output data stream and a second audio/video output data id stream, wherein the broadcast audio/video data stream contains information corresponding to an audio/video work and the first audio/video output stream is in a format that can be recognized and processed by conventional audio/video reproducing equipment; a storage device that stores data included in the second audio/video output data stream, wherein the data corresponds to the audio/video work; and a user interface that enables a user of the system to input to the system an indication that the user desires to purchase the audio/video work.

A personalized audio system and method that overcomes many of the broadcast-type disadvantages associated with conventional radio stations. According to one embodiment, the personalized audio system includes the following: (1) a user interface that enables a user of the personalized audio system to specify a profile for a personalized audio channel, (2) a sound recording library comprising a plurality of sound recordings, (3) a playlist generator that (a) selects a plurality of sound recording identifiers from a set of sound recording identifiers, wherein each of the plurality of sound recording identifiers identifies a sound recording that matches the profile and that is stored in the library, and that (b) creates a playlist that lists the plurality of sound recording identifiers in a particular order, and (4) a sound recording reproducing device for reproducing the plurality of identified sound recordings according to the particular order in which the sound recording identifiers are listed in the playlist so that the user can listen to the sound recordings. Advantageously, the personalized audio system does not provide the user with a way to determine the plurality of sound recording identifiers prior to the reproducing means reproducing the plurality of sound recordings, and the personalized audio system does not provide the user with a way to directly control which sound recording identifiers in the set are selected by the playlist generator to be included in the plurality of sound recording identifiers.
