Abstract: This application relates to systems and methods for recovering data in multimedia file segments. A communication device may receive a multimedia file segment that includes damaged data. The communication device may replace the damaged data with dummy data to reconstruct the multimedia file segment. The communication device may then play the reconstructed multimedia file segment. Thus, by replacing the damaged data with dummy data, the communication device may play a multimedia file segment even when part of the segment may be damaged.

Abstract: Systems, methods, and receiver devices enable broadcasters with restricted content license areas (e.g., Designated Market Areas (“DMAs”) to distribute content via Over the Top (“OTT”) IP networks. Embodiments enable client reporting and authentication as well as broadcast content encryption. In an embodiment, information from the client may be reported back to the broadcasters, such as a view history/use report. In an embodiment, hand off between DMAs may be enabled. In an embodiment, local advertisement insertion in network content may be enabled. Embodiments may enable Multicast-Broadcast Single Frequency Network (“MBSFN”) operation across DMA boundaries.

Abstract: Techniques for sending and receiving broadcast information are described. In an aspect, broadcast metadata may be generated for broadcast information and may include location and time criteria used by terminals to filter the broadcast information. Each location and time criterion may include (i) a location criterion given by a target location and a presence or absence requirement and (ii) a time criterion given by a time period in which the location criterion applies. A terminal may receive the broadcast metadata prior to or with the broadcast information, obtain location and time criteria from the broadcast metadata, and filter the broadcast information based on the location and time criteria. The terminal may evaluate each location and time criterion by determining its location within a specified time period and determining whether its location is within or outside a specified target location, as indicated by the presence or absence requirement.
