A broadcast signal transmission method comprises outputting an RoHC channel that includes one or more RoHC streams and a signaling table that includes information related to header compression by performing header compression for Internet Protocol (IP) packets, which include broadcast data, in accordance with an adaptation mode, a header of each IP packet including an IP header and a User Datagram Protocol (UDP) header, generating at least one first link layer packet that includes the RoHC channel and generating at least one second link layer packet that includes the signaling table, and physical layer processing the at least one first link layer packet and the at least one second link layer packet and transmitting through one or more Physical Layer Pipes (PLPs), wherein the signaling table includes adaptation mode information indicating the adaptation mode, and each RoHC stream in the RoHC channel includes RoHC packets.

A process for modifying wireless data compression for a wireless electronic device includes displaying an application for modifying data compression on a display of the electronic device. The process further includes receiving a request from a user to modify a current data compression with a new data compression through an input device, evaluating the requested new data compression request in view of predetermined information of the user with a processor, and updating the wireless data compression with the new data compression after the evaluation with the processor.

Aspects of the subject technology relate to systems and methods for optimizing telemetry schemes with a constant insensible group delay. Systems and methods are provided for receiving an acquisition including compressed data and dummy data from a downhole logging system, determining a prior decompressor queue size based on the acquisition for a plurality of time intervals, determining a decompressor data size based on the acquisition for the plurality of time intervals, and determining a delay where the prior decompressor queue size is continuously greater than or equal to the decompressor data size for the plurality of time intervals.

Various examples and schemes pertaining to simple Ethernet header compression are described. A first network node transmits a first packet with a full header to a second network node. The first network node determines whether a header compression context for the full header has been established by the second network node. In response to determining that the header compression context for the full header has been established by the second network node, the first network node transmits a second packet with a compressed header to the second network node. In response to determining that the header compression context for the full header has not been established by the second network node, the first network node transmits the second packet or a third packet with the full header to the second network node.
