Abstract: A system and method enable a wireless device to support simultaneously multiple push-to-talk (PTT) communications and interrupt certain PTT communication with higher priority ones. A user subscribes to multiple PTT communication groups and designates one of the groups as the primary group. The wireless device receives and plays PTT communications from the multiple PTT communication groups and interrupts playing of a PTT communication from a non-primary group if a PTT communication is received from the primary PTT communication group.

Abstract: In a digital cinema system, a method for creating a playlist is claimed. At least one image program and at least one audio program is displayed. Each image program comprises encoded data representing image information, and each audio program comprising encoded data representing audio information. Responsive to image programs and audio programs being specified, compatibility of selected image programs and selected audio programs is verifying.

Abstract: The invention provides a method of storing trailer data and feature data on at least one storage medium. The method includes the steps of partitioning each storage medium into first portions and second portions. The compressed trailer data is stored onto at least one of the first portions. The compressed feature data is stored onto at least one of the second portions.

Abstract: In a digital cinema system comprising a decoder and an auditorium manager, where the auditorium manager configured to sequence the presentation of scheduled programs, a method of cueing a theatre automation system is claimed. A cue command is received from the decoder. The cue command is configured to a format acceptable by the theatre automation system. The cue command is then relayed to the theatre automation system.

Abstract: In a digital cinema system comprising a decoder, a theater automation system and an auditorium manager, a method for monitoring playback of a playlist is claimed. An elapsed time and a total time of the playlist are displayed. The theater automation system periodically synchronizes with the decoder to fetch status information from the decoder, which is then displayed.

Abstract: An apparatus for the storage of a first group and a second group of data on at least one storage medium is claimed. The apparatus comprises a storage space allocator configured to partition the first storage medium into a first segment and a second segment. A comparer is configured to compare the space needed to store the first group of data with the amount of space available on the first segment and to compare the space needed to store the second group of data with the amount of space available on the second segment. A separator is configured to separate the first group of data into a first primary portion and a first secondary portion if the space needed to store the first group of data is greater than the amount of space available on the first segment, and to separate the second group of data into a second primary portion and a second secondary portion if the space needed to store the second group of data is greater than the amount of space available on the second segment.
