Once you've recorded a round or two and are ready to watch and study your ShotKam videos, this is how we suggest you do so. ( 6)12, 1384–1397 (2007).These tutorials will show you how to watch your ShotKam videos on a computer using a third party media player called VLC.

Finally, we evaluate the effectiveness of SDRA by means of Monte Carlo analysis in several scenarios, involving mixed Voice over IP (VoIP) and Best Effort (BE) MSs with varied modulations, with different sub-carrier permutations and frequency re-use plans. Allocation is carried out by means of the Sample Data Region Allocation algorithm (SDRA), which also supports Hybrid Automatic Repeat Request (H-ARQ), an optional feature of IEEE 802.16e. the definition of the position and shape of the data regions according to a set of scheduled grants, from the QoS requirements of connections. We then propose a modular framework to solve the frame allocation problem, which decouples the constraints of data region allocation into the MAC frame, i.e. Through a detailed analysis of the standard, we show that the latter is an overly complex task. ![]() We refer to the process of defining the content of map messages as frame allocation. This is done on a frame-by-frame basis by defining the content of map messages, which advertise the position and shape of data regions reserved for transmission to/from MSs. The Base Station (BS) is responsible for allocating data into the frames so as to meet the Quality of Service (QoS) guarantees of the Mobile Stations’ (MSs) admitted connections. In OFDMA, the MAC frame extends over two dimensions: time, in units of OFDMA symbols, and frequency, in units of logical sub-channels. To this end, Orthogonal Frequency Division Multiple Access (OFDMA) is specified as the air interface. The IEEE 802.16e standard specifies a connection-oriented centralized Medium Access Control (MAC) protocol, based on Time Division Multiple Access (TDMA), which adds mobility support defined by the IEEE 802.16 standard for fixed broadband wireless access.
