    摘要: An audio encoding scheme or a stream that encodes audio and video data is disclosed. The scheme has particular application in mezzanine-level coding in digital television broadcasting. The scheme has a mean effective audio frame length F that equals the video frame length 1/fV over an integral number M video frames, by provision of audio frames variable in length F in a defined sequence where length=F(j) at encoding. The length of the audio frames may be varied by altering the length of overlap between adjacent frames in accordance with an algorithm that repeats after a sequence of M frames. An encoder and a decoder for such a scheme are also disclosed.

    摘要: The invention relates to a system for content selection. A consumer apparatus (101), such as a video recorder, comprises a receiver (103) for receiving content items from a plurality of sources (105, 107, 109, 111). The content items include real-time content items such as TV channels received from broadcast transmitters (105). The content items further include stored content items. The consumer apparatus (101) further comprises a presentation processor (113) which determines an earliest and a latest time of availability for each content item. The available content items are presented in a content set indication, which comprises indications of the earliest and latest times of availability for each content item. A user may select a content item simply by considering the availability times, and need not consider the nature or source of origin of a content item. Hence, an integrated selection list of content items may be provided for content items received from a plurality of various sources.
