The Heidi Game

For the internet radio game show sometimes referred to as GSN Live, see. GSN Live Presented by Country of origin United States Original language(s) English Production Running time 3 hours (until September 12, 2008; since October 12, 2009) 6 hours (September 15, 2008 - October 9, 2009) Release Original network Original release February 25, 2008 ( 2008-02-25) – July 29, 2011 ( 2011-07-29) GSN Live is an American live show on that premiered on February 25, 2008 at noon and officially ended its 3-year run on July 29, 2011. The last 'live' edition aired May 13, 2011. It lasted three hours in between regular GSN programming and featured games that viewers played to win prizes over the phone, highlights from Classic game shows, interviews, behind-the-scenes views of GSN, and celebrity appearances.

It was formerly hosted in two shifts. The first shift, from noon to 3 PM ET was hosted by (with until August 11, 2009). Hosted the 3 PM to 6 PM ET segment. Was Roggin's co-host from September 15, 2008 to November 28, 2008 and Roggin co-hosted the 3 hours with rotating guest hosts until was chosen to replace Packard on May 26, 2009, the same day the current set was introduced and when it was hosted by three people. Fred Roggin left GSN Live on July 2, 2009, Alfonso Ribeiro left GSN Live on August 11, 2009, Debra Skelton left GSN Live on January 2010, and Heidi Bohay left the show in April 2010, making currently the sole host. The show was executive produced by Burt Dubrow until March 6, 2009, and is currently produced by John Berkson, Gary Green, and Laura Slobin.

The sound mixer was Mike Dooley. Budget cuts implemented by the new GSN executive regime are causing the almost weekly dismissals of production staff members from the show. Due to these cuts the show was cut from six hours to three hours and now runs from 3 PM to 6 PM ET. The staff was cut by 7 effective December 30, 2009, leaving the future of the show in question. The show has run for three hours daily, 12 PM to 3 PM ET from its debut until September 12, 2008 and since October 12, 2009 from 3 PM to 6 PM ET. The hosts for the three-hour show were and. On September 15, 2008, it expanded to six hours daily and ran from 12 PM to 6 PM ET until October 9, 2009.

GSN Live was on hiatus for the week of May 18 to May 25, 2009 to transition to a new set, and returned on May 26, 2009. Contents. Format The interactive games on GSN Live are interspersed during regular programming for a short time when commercials would normally run. Games are introduced at the beginning of an hour and played by a caller near the end of the hour.

There is only one player for each game. Entries can be made on the internet or over the phone, both having an equal chance of selection.

Every individual who logs on or calls to enter, whether they are chosen to play on the air live or not, is entered into a 'Weekly Prize Bonanza' drawing for which a single prize is awarded once a week. Prizes in the first three weeks included a vacation package, diamond watches, and a cruise. (Currently, the prize is awarded monthly.) In addition, all contestants who play on-air are currently awarded 2,500 'Oodles,' (5,000 on 'Winner Wednesday' shows) an offered to GSN website users. At the beginning of March, the show introduced another way home viewers can win called 'Steal These Wheels'. All contestants chosen to play live on the air were entered into a drawing for a new, which was awarded on the first day of April. Generally, during the final segment of the show, the hosts presented three keys with labels showing the first names and towns of that day's players, then placed them into a glass tumbler, referred to as a 'hopper'.

The hosts had a running gag that the car was parked in host Fred Roggin's parking spot, thus making the spot unavailable for his own car. GSN Live logo from February 2008 – May 2009 On April 1, 2008, a name was pulled from the hopper, and the PT Cruiser was awarded to a male contestant living in. Host Heidi Bohay then surprised viewers by announcing that 'Steal These Wheels' would continue for a second month, with a being the prize.

During the final week of March, regular host Fred Roggin took a one-week vacation. In his absence, game show legend and celebrity emcee took his place. Regularly, throughout the week, Martindale made jokes centering on Roggin's absence, such as finding a wallet full of cash tucked inside the host chair and revealing to the audience that Fred was not on vacation, but was, in fact, on the run from the police. While Fred was in Beijing, China for 's Olympic coverage, several hosts filled in, including Martindale, and. The hosts have increasingly taken a light-hearted approach to the show's material, gently poking fun at the classic game shows on the GSN schedule and their sometimes anachronistic elements, the network itself, and each other.

RIP version 1 (v1) is defined in RFC 1058 and is widely deployed in small to medium-sized intranets. RIP v1 Message Format RIP messages are encapsulated in a User Datagram Protocol (UDP) datagram sent from the router interface IP address and UDP port 520 to the subnet broadcast IP address. The RIP v1 message consists of a 4-byte RIP header and up to 25 RIP routes.

The maximum size of the RIP message is 504 bytes. With the 8-byte UDP header, the maximum size of the RIP message is a 512-byte IP payload. Figure 3.8 illustrates the RIP v1 message format. Figure 3.8 RIP Version 1 Message Format Command A 1-byte field containing either 0x01 or 0x02. 0x01 indicates a RIP request for all (a General RIP Request) or part of the routing tables of neighboring routers. 0x02 indicates a RIP response consisting of all or part of a neighboring router's routing table. A RIP response can be sent in response to a RIP request or as the periodic or triggered update message.

Version A 1-byte field set to the value of 0x01 for RIP v1. Family Identifier A 2-byte field identifying the protocol family. This is set to the value of 0x00-02 to indicate the IP protocol family. IP Address A 4-byte field set to the IP network ID which can be a class-based network ID, a subnetted network ID (advertised only within the subnetted network), an IP address (for a host route), or 0.0.0.0 (for the default route). For a General RIP Request, the IP Address is set to 0.0.0.0. Metric A 4-byte field for the number of hops to the IP network that must be a value from 1 to 16. The metric is set to 16 in a General RIP Request or to indicate that the network is unreachable in a RIP response (announcement).

Problems with RIP v1 RIP v1 was designed in 1988 to suit the dynamic routing needs of LAN technology–based IP internetworks. Shared access LAN technologies like Ethernet and Token Ring support Media Access Control (MAC)–level broadcasting where a single packet can be received and processed by multiple network nodes. However, in modern internetworks, the use of MAC-level broadcasts is undesirable because all nodes must process all broadcasts. RIP v1 was also designed in a time when the Internet was still using network IDs based on the Internet address classes. Today, however, the use of Classless Inter-Domain Routing (CIDR) and variable length subnetting is almost required to conserve IP addresses. Broadcasted RIP Announcements All RIP v1 route announcements are addressed to the IP subnet (all host bits are set to 1) and MAC-level broadcast. Non-RIP hosts also receive RIP announcements.

For large or very large RIP internetworks, the amount of broadcast traffic on each subnet can become significant. While producing additional broadcast traffic, the broadcast nature of RIP v1 also permits the use of Silent RIP. A Silent RIP computer processes RIP announcements but does not announce its own routes. Silent RIP could be enabled on non-router hosts to produce a routing table with as much detail as the RIP routers. With more detailed routes in the routing table, a Silent RIP host can make better routing decisions. Subnet Mask Not Announced with Route RIP v1 was designed for class-based IP internetworks where the network ID can be determined from the values of the first 3 bits of the IP address in the RIP route. Because the subnet mask is not included with the route, the RIP router must determine the network ID based on a limited set of information.

For each route in a RIP v1 message, the RIP v1 router performs the following process:. If the network ID fits the address classes (Class A, Class B, or Class C), the default class-based subnet mask is assumed.

If the network ID does not fit the address class, then:. If the network ID fits the subnet mask of the interface on which it is received, the subnet mask of the interface on which it was received is assumed. If the network ID does not fit the subnet mask of the interface on which it is received, the network ID is assumed to be a host route with the subnet mask 255.255.255.255. As a result of the assumptions listed previously, supernetted routes might be interpreted as a single network ID rather than the range of network IDs that they are designed to represent and subnet routes advertised outside of the network ID being subnetted might be interpreted as host routes.

As a mechanism for supporting subnetted environments, RIP v1 routers do not advertise the subnets of a subnetted class-based network ID outside the subnetted region of the IP internetwork. However, because only the class-based network ID is being advertised outside the subnetted environment, subnets of a network ID in a RIP v1 environment must be contiguous. If subnets of an IP network ID are noncontiguous, known as disjointed subnets, the class-based network ID is announced by separate RIP v1 routers in different parts of the internetwork. As a result, IP traffic can be forwarded to the wrong network.
