In one embodiment, a system comprises a processor to retrieve a first data element including a value Xand Y, provide a hash function for use with a hash table having buckets, the hash function having a first and second input that in combination map to one of the buckets wherein the first input is in a range of X-values having X-value sub-ranges, the second input is in a range of Y-values having Y-value sub-ranges, different combinations of the X-value sub-ranges and the Y-value sub-ranges map using the hash function to different buckets, and input the value Xand Yinto the hash function yielding an output which is indicative of a first bucket of the hash-table. Related apparatus and methods are also described.

Storing and retrieval heuristics

A method for facilitating multiple recordings via a single tuner includes isolating data packets associated with recording candidate media assets from at least two broadcast data streams, generating at least one broadcast recording data stream from a subset of the isolated data packets, broadcasting the at least one broadcast recording data stream in parallel with the at least two broadcast data streams, where the broadcast recording data stream is broadcast via at least one dedicated broadcast 'recording' device, and the at least two broadcast data streams are broadcast via other broadcast devices, storing remaining data packets not included in the isolated data packets in broadband data segments, and transmitting the broadband data segments via an IP connection to facilitate reassembly of partially recorded the media assets, where the partially recorded media assets were recorded from the broadcast recording stream. Related methods and apparatus are also disclosed.

System and method for simultaneously recording multiple media assets using a single tuner

In one embodiment, a system includes a processor to retrieve, from a memory, data of a video frame, the data including measurements of luminance, each of the measurements of luminance being associated with a different entry in a matrix, calculate a weighted average luminance value Ly for the measurements of luminance weighted according to a row position of the one measurement of luminance in the matrix, calculate a weighted average luminance value Lx for the measurements of luminance weighted according to a column position of the one measurement of luminance in the matrix, and create a video signature, S, of the video frame, the video signature, S, including the weighted average luminance value Ly and the weighted average luminance value Lx. Related apparatus and methods are also described.
