Cable television return link system with high data-rate side-band communication channels
TLDR
In this article, a control logic circuit (227) and multiplexor (231) are configured to monitor a fullness level of the RF data memory device (223-1, 220-2) and maintenance data memory (229).Abstract:
The CATV digital return link system includes return path transmitters, intermediate hubs and a headend hub coupled to each other via a network of fiber optics cables. A pair of data-in multiplexors (221-1, 221-2) process the latched data from latches (220-1, 220-2), the 16-bit data words from the data-in multiplexors (221-1, 221-2) are then forwarded to a pair of data memory devices (223-1, 223-2). A control logic circuit (227) of the signal processing logic (204) is configured to generate read and write addresses for the various memory devices. The control logic circuit (227) and multiplexor (231) are configured to monitor a fullness level of the RF data memory device (223-1) and maintenance data memory (229).read more

Networked subscriber television distribution
TL;DR: In this article, a master device interactively distributes a television signal to a remote device for remote display with low latency between a user input and a TV signal change, where the master device can control the remote device with a remote controller.
Patent
Minimizing channel change time for ip video
TL;DR: In this paper, the channel changing delay can be minimized by caching video packets for the most likely next channel in a buffer in anticipation of a television subscriber changing channels and/or by having an adaptable buffer length in the set top box.
